History (500 – 1500)

The Byzantine Foundation (500–700)

The story of medieval gold begins with Byzantium. The Byzantine Empire inherited Rome’s monetary system, centered on the gold solidus—a coin that would prove remarkably stable for over seven centuries. Under Emperor Justinian I (527–565), Byzantine gold financed ambitious military campaigns to reconquer the former Western Roman Empire, with successful expeditions into North Africa, Italy, and southern Spain. The solidus became more than just currency; it represented economic stability in an uncertain age.

Byzantine gold reached far beyond the Mediterranean. Archaeological evidence reveals solidi accumulating in the Baltic region as payment for furs, demonstrating trade networks extending deep into northern Europe’s amber and fur territories. By 600–700, Byzantine gold coins were being hoarded across France, the Low Countries, Scandinavia, Germany, the Balkans, Russia, the Levant, and North Africa, serving as an international standard of value across diverse cultures and economic systems.

The solidus earned such trust that around 800, an Arab merchant’s manual recommended Byzantine gold coins as the safest currency for long-distance trade, noting they could be used “from the lands of the Franks to China” without need for assay or verification. This unmatched international reputation spanning three continents would endure even as Byzantium faced military and economic challenges.

The Islamic Gold Revolution (638–750)

The rise of Islam transformed the medieval gold economy. Arab Muslim forces conquered Byzantine Syria, Palestine, Egypt, and Sassanid Persia between 638 and 642, gaining control of substantial gold reserves and bullion sources. Initially, Islamic authorities continued minting imitative Byzantine-style gold coins, but this transitional period would not last.

In 696–697, Caliph Abd al-Malik ibn Marwan issued the first fully reformed Islamic gold dinar, weighing 4.25 grams (one mithqal) and establishing a new weight standard distinct from the Byzantine solidus. This reform created an independent Islamic monetary system and established the dinar as the gold standard for the Islamic world for the next millennium.

The Umayyad conquest of Visigothic Spain (711–718) brought Islamic gold dinars to the Iberian Peninsula, where Spain became a major Islamic gold coinage producer. Under the Abbasid Caliphate (750–1258), ruling from Baghdad, the gold dinar standard expanded across a vast monetary zone stretching from Spain to Central Asia. During the reign of Caliph Harun al-Rashid (786–809), Islamic gold dinars achieved peak circulation and acceptance, with gold flowing from Africa through trans-Saharan trade routes to North African mints.

Western Europe’s Silver Age (700–1250)

While gold flourished in Byzantium and the Islamic world, Western Europe entered what might be called its “silver age.” Around 700–720, Merovingian Francia produced the last Western European gold coins for over five centuries. Economic changes and lack of gold supplies made gold impractical for everyday commerce in the north and west.

Charlemagne’s major currency reforms of 793–794 established the Carolingian monetary system based on silver, with gold virtually disappearing from Western European minting. His son Louis the Pious (813–840) issued extremely rare Carolingian gold solidi, among the last Byzantine-style gold coins struck in the West, likely serving diplomatic and prestige functions rather than circulating as regular currency.

One remarkable anomaly appeared in 774 when King Offa of Mercia minted a gold coin copying an Abbasid dinar, complete with Arabic inscriptions and the Islamic declaration of faith. This extraordinary coin, possibly intended for trade with the Islamic world or as payment to the papacy, demonstrates how Islamic coinage had become the international model even in distant Anglo-Saxon England.

The Fatimid Ascendancy (909–1171)

The Fatimid Caliphate emerged as a new force in Mediterranean gold markets. Ruling first from Tunisia and later from Egypt, the Fatimids produced exceptionally high-quality gold dinars known for their distinctive “red gold” purity approaching 99%. These became the most widespread and trusted trade coins of the Mediterranean, rivaling and eventually surpassing Byzantine gold in commercial importance.

When Fatimid general Jawhar al-Siqilli conquered Egypt in 969, he immediately began minting extremely pure gold dinars in Cairo to establish monetary authority. Four years later, Caliph al-Mu’izz arrived in Egypt with reportedly one hundred camel-loads of gold bars to establish Fatimid currency dominance. This massive transfer of bullion enabled the Fatimids to flood the market with high-quality dinars and displace competing currencies.

The Fatimid achievement was particularly notable given what was happening to Byzantine gold during the same period.

Byzantine Decline and Crisis (1028–1092)

After seven centuries of monetary stability, Byzantine gold entered a catastrophic decline. Beginning in 1028–1034, Emperor Romanos III Argyros reduced the nomisma’s fineness from the traditional 24 carats. His successor Michael IV (1034–1041), a former moneychanger, took the unprecedented step of significantly debasing the gold solidus—perhaps his background in currency exchange influenced his willingness to break with centuries of monetary tradition.

By 1043, Italian merchants in Constantinople’s markets were rejecting debased Byzantine gold nomismata, demanding payment only in older, full-weight coins. This marked Gresham’s Law in action: “bad money drives out good,” as people hoarded quality coins and spent debased ones.

The Byzantine defeat at Manzikert in 1071 accelerated the crisis. Loss of most of Anatolia drastically reduced imperial tax revenues and gold supplies. By 1071–1078, gold purity had dropped to approximately 14 carats (58% gold) under Michael VII Doukas. Under Nikephoros III Botaneiates (1078–1081), it fell further to approximately 8 carats—barely one-third gold content.

During the first eleven years of Alexios I Komnenos’s reign (1081–1092), Byzantine gold coins ranged from 0 to 8 carats, with some issues essentially copper coins with gold wash. The Byzantine gold currency had reached its nadir.

In 1092, Alexios enacted comprehensive monetary reform, replacing the debased solidus with the hyperpyron (“super-refined”) at 20.5 carats fine gold (approximately 85% pure). While not achieving the ancient solidus’s purity, the hyperpyron restored significant value and confidence, establishing a new three-metal system with gold hyperpyra, electrum trachea, and billon trachea in fixed ratios. However, Byzantine gold would never fully recover its former glory.

The Crusades and Gold (1095–1291)

The Crusades fundamentally reshaped European relationships with gold. When Pope Urban II launched the First Crusade in 1095, he promised both spiritual rewards and material plunder. The subsequent looting of wealthy Byzantine and Islamic cities flooded Western Europe with gold coins, jewelry, and precious objects, providing many knights their first direct contact with substantial quantities of gold.

The Crusades brought tens of thousands of Western Europeans into contact with sophisticated Byzantine and Islamic gold coinage systems far beyond their native economies. After capturing Jerusalem in 1099, crusaders encountered these monetary systems firsthand. The Latin Kingdom of Jerusalem subsequently began minting gold bezants copying Islamic models to facilitate trade and taxation.

Gold played a dramatic role in crusader politics. In 1123, Baldwin II of Jerusalem was ransomed for the enormous sum of 80,000 gold pieces, nearly bankrupting the Latin Kingdom. During the Third Crusade (1189–1192), Richard I of England and Philip II of France transported enormous quantities of gold to finance their armies in the Holy Land.

The most catastrophic episode came in 1204 when the Fourth Crusade, originally intended for Egypt, instead sacked Constantinople—the greatest Christian city. This disaster permanently weakened the Byzantine Empire and dispersed Byzantine gold treasures, relics, and art across Western Europe, including the famous horses of St. Mark’s now in Venice.

The fall of Acre in 1291 eliminated the last major Crusader stronghold in the Holy Land, ending direct European military presence and forcing adaptation to Islamic-controlled gold trade networks. The crusading era had exposed Europe to Eastern gold wealth but ultimately demonstrated that European access to Eastern gold markets depended more on negotiation and trade than military conquest.

West African Gold and Trans-Saharan Trade (1100–1500)

While Europeans fought over Eastern Mediterranean gold, the most important source of medieval gold lay in West Africa. During the 12th century, approximately 60% of gold circulating in Europe originated from West African sources, transported north across the Sahara through trading centers like Sijilmasa. The empires of Mali and Ghana controlled crucial gold-producing regions in Bambuk and Bure.

The Almoravid dynasty (1085–1147), controlling Morocco, Algeria, and southern Spain, produced high-quality gold dinars from West African gold supplies through their control of trans-Saharan trade routes. Their successors, the Almohads (1147–1269), continued this pattern with distinctive square-shaped gold coins.

The most legendary figure in this trade was Mansa Musa, ruler of the Mali Empire. During his famous pilgrimage to Mecca in 1324, his caravan passed through Cairo with an entourage of 60,000 people, including 12,000 slaves, and 80–100 camels carrying gold. His extravagant spending and gift-giving flooded the Egyptian gold market so dramatically that it caused approximately 20–25% devaluation of the gold dinar in Cairo, disrupting the Egyptian economy for about 12 years. Arab chroniclers visiting Cairo 12 years later found residents still discussing Musa’s unprecedented generosity.

The 1375 Catalan Atlas depicted Mansa Musa seated on a throne holding a gold nugget and scepter, spreading knowledge of West African gold wealth to European royal courts. This map inspired Portuguese interest in accessing African gold sources directly by sea, bypassing Muslim intermediaries.

The Return of European Gold Coinage (1252–1500)

In 1252, a revolution occurred: Florence minted the first gold florin, the first European gold coin struck in sufficient quantities since the 8th century to function as regular trade currency rather than merely a prestige object. Weighing 3.5 grams of 24-carat gold, the florin featured Florence’s lily on the obverse and St. John the Baptist on the reverse. Genoa simultaneously introduced the gold genovino at similar specifications, though it never achieved the florin’s international acceptance.

Venice responded in 1284 with the gold ducat, weighing 3.545 grams of 99.47% pure gold—the highest purity achievable through medieval cupellation techniques. When Venice introduced the ducat, the Great Council decreed the death penalty for mint workers who debased the coinage. This draconian law, combined with rigorous quality control, maintained the ducat’s purity for over 500 years, making it more trusted than signed contracts. The ducat’s slightly higher weight and purity, combined with Venice’s vast maritime trade network, eventually made it the Mediterranean’s dominant trade coin.

Other European powers followed. France issued the gold écu under Louis IX in 1266. England’s attempts were more halting—the 1257 gold penny under Henry III failed due to impractical denomination, and various gold coins under Edward III (1327–1377) preceded the successful establishment of the noble and its derivatives. England finally achieved sustained gold coinage success with the gold angel (1465) and the first gold sovereign (1489) under Henry VII.

Hungarian Gold and European Production (1300–1500)

Before the discovery of the Americas, Europe had one major indigenous gold source: Hungary. Hungarian gold mines, particularly in Kremnica (in modern Slovakia) and other locations in the Carpathian Mountains, produced approximately 450,000–500,000 kilograms of gold between 1300 and 1500, with annual output reaching 1,400–2,250 kilograms. From the 1330s until the Spanish conquest of the Americas in the 1490s, this represented approximately 30% of world gold production.

Charles I of Hungary began systematic gold coinage in 1311, exploiting ancient Roman gold mines. Hungarian gold florins, initially called “floreni” after the Florentine model, became known as “forint” and achieved wide international acceptance. This domestic gold production helped sustain European monetary systems during the late medieval period.

The Great Bullion Famine (1457–1464)

Despite these developments, Europe faced severe gold shortages. The Great Bullion Famine of 1457–1464 resulted from multiple factors: increased European trade with Asia drained gold eastward; Atlantic African gold sources hadn’t yet been fully developed; and European mines faced declining yields. The shortage caused severe economic disruption and stimulated the search for new bullion sources.

Mamluk Sultan Barsbay’s 1429 attempt to monopolize pepper trade, demanding payment exclusively in gold dinars, forced European merchants to ship even more gold eastward. A Chinese official visiting Hormuz in 1422 reported seeing bazaars where “gold dinars are piled up like firewood,” describing the enormous quantities flowing through Indian Ocean trade routes between Africa, the Middle East, and Asia—wealth that rarely reached Europe.

Portuguese Exploration and African Gold (1415–1500)

Portugal pioneered the solution to Europe’s gold shortage. Portuguese forces captured Ceuta in Morocco in 1415, initiating systematic exploration of West African coastal gold resources. This marked the beginning of European attempts to bypass trans-Saharan trade controlled by Muslim merchants and access African gold directly.

By 1441, Portuguese reached gold-producing regions directly, establishing trading posts. In 1471, they established São Jorge da Mina (Elmina Castle) on the Gold Coast, securing direct access to West African gold. This fort became the center of Portuguese gold trade, handling hundreds of kilograms annually. The 1479 Treaty of Alcáçovas between Portugal and Spain divided African trade rights, with Portugal securing exclusive access to Gold Coast trade.

By the 1500s, Portuguese traders handled approximately 400–550 kilograms of West African gold annually through their coastal forts. This gold, brought from interior sources by African merchants, enriched Portugal and helped finance the Portuguese maritime empire’s expansion into Asia.

The Fall of Constantinople and Ottoman Gold (1453–1500)

The medieval period’s symbolic end came in 1453 when Ottoman Sultan Mehmed II conquered Constantinople, definitively ending the Byzantine Empire and its millennium-long gold currency tradition. The Ottomans subsequently developed their own gold coinage, the sultani (also called altun), based on Venetian ducats, beginning in 1478. By 1476, a Venetian merchant described seeing Ottoman Sultan Mehmed II’s treasury containing “gold coins stacked higher than a man’s head in rooms the size of churches,” reflecting how Ottoman conquests concentrated vast quantities of gold in Constantinople.

Legacy and Transformation

By 1500, the medieval gold economy stood poised for revolutionary transformation. On the eve of Columbus’s departure in 1491, the Spanish monarchs’ entire annual revenue was approximately 12,500 gold ducats—about 44 kilograms of gold. Within decades, Spanish America would produce this quantity monthly, revolutionizing the global economy.

The medieval period had witnessed gold’s transformation from Byzantine imperial currency to Islamic commercial standard, from crusader plunder to West African trade commodity, and finally to the foundation of renewed European monetary systems. The Venetian ducat and Florentine florin had established standards that would influence coinage for centuries. Hungarian mines and Portuguese African trading posts had demonstrated Europe’s growing capacity to secure its own gold supplies.

Most importantly, these thousand years had created the commercial networks, banking systems, and monetary technologies that would enable the early modern global economy. The quest for gold had connected civilizations, driven exploration, and financed everything from cathedral construction to crusading armies. As Europe stood on the threshold of American conquests, the medieval experience with gold had prepared the institutional and commercial frameworks that would manage—and be transformed by—the unprecedented influx of New World precious metals that lay just ahead.

Chronology

The medieval period witnessed an unprecedented circulation of gold across continents, with the precious metal serving as both currency and symbol of power. Trade routes spanning from Scandinavia to sub-Saharan Africa, from Ireland to China, carried not just gold coins but ideas, technologies, and cultural exchanges that would shape world history:

500-550 CE – Byzantine gold solidi accumulate in the Baltic region as payment for furs, demonstrating the extensive reach of Byzantine trade networks that extended far beyond the Mediterranean world into northern Europe’s amber and fur-producing territories.
527-565 – Emperor Justinian I uses Byzantine gold wealth to fund his ambitious military campaigns aimed at reconquering the former Western Roman Empire, including successful campaigns in North Africa, Italy, and southern Spain. The gold solidus remains the empire’s principal currency for military payments and taxation, maintaining its reputation as the most stable gold coin in circulation.
534-536 – Justinian’s conquest of Vandal North Africa reopens the mint at Carthage, which becomes a major producer of gold solidi until the Arab conquest in 698. Carthage’s gold production significantly contributes to Byzantine gold circulation in the western Mediterranean.
568-572 – Lombard invasion of Italy disrupts Byzantine control of Italian mints, reducing Western gold production. However, Byzantine mints at Ravenna and Rome continue striking solidi, maintaining gold currency circulation in remaining Byzantine territories.
600-700 – Byzantine gold solidi are hoarded across France, the Low Countries, Scandinavia, Germany, the Balkans, Russia, the Levant, and northern Africa, serving as international trade currency and store of wealth. Archaeological finds from this period reveal the solidus’s role as a universal standard of value across diverse cultures and economic systems.
602-610 – Emperor Phocas issues gold solidi depicting the emperor holding a cross on globe, establishing Christian iconography as a permanent feature of Byzantine gold coinage. This innovation reflects the Byzantine Empire’s identity as a Christian state and influences later Islamic decisions to avoid figural imagery on coins.
610-641 – Emperor Heraclius’s wars against Sassanid Persia severely drain Byzantine gold reserves. Despite ultimately defeating Persia, the wars exhaust both empires financially, setting the stage for rapid Arab conquest of both territories in the following decades.
615 – Emperor Heraclius introduces the gold hexagram alongside the gold solidus to finance his expensive wars against Sassanid Persia.
625-629 – During Heraclius’s Persian campaigns, Constantinople itself is besieged by combined Avar and Persian forces. The empire’s survival depends on maintaining gold payments to the army and navy, demonstrating gold currency’s critical strategic importance.
638-642 – Arab Muslim forces conquer Byzantine Syria, Palestine, Egypt, and Sassanid Persia, gaining control of substantial gold reserves and bullion sources. Early Islamic authorities initially continue minting imitative Byzantine-style gold coins with modified imagery.
696-697 – Caliph Abd al-Malik ibn Marwan issues the first fully reformed Islamic gold dinar weighing 4.25 grams (one mithqal), establishing a new weight standard distinct from the Byzantine solidus. This reform creates an independent Islamic monetary system and establishes the dinar as the gold standard for the Islamic world for the next millennium.
ca. 700-720 – Merovingian Francia produces the last Western European gold tremisses (one-third solidi), marking the end of regular gold coinage in Northwestern Europe for over five centuries. Economic changes and lack of gold supplies make gold impractical for everyday commerce.
711-718 – Umayyad forces conquer Visigothic Spain, bringing Islamic gold dinars into circulation on the Iberian Peninsula. Spain becomes a major Islamic gold coinage producer, with mints at Córdoba and other cities.
750-969 – Under Abbasid rule, Jerusalem prospers with significant gold trade as pilgrims and merchants converge on the holy city, though it doesn’t achieve the political or economic status of major Islamic capitals like Baghdad, Damascus, or Cairo.
750-1258 – The Abbasid Caliphate, ruling from Baghdad, maintains the gold dinar standard established by the Umayyads. Abbasid dinars circulate from Spain to Central Asia, creating a vast unified monetary zone.
755 – Frankish King Pepin the Short introduces the denier (penny), marking the decisive shift from gold coinage in northern Europe.
774 – King Offa of Mercia mints a remarkable gold coin copying an Abbasid dinar dated AH 157 (773-774 CE), complete with Arabic inscriptions and the Islamic declaration of faith (shahada). The actual minting date is uncertain but likely occurred after 774, possibly around 786 when Offa made his vow to send annual gold payments to Rome. This extraordinary coin demonstrates the reach of Islamic coinage as a model and may have been intended for trade with the Islamic world or as payment to the papacy. It remains one of the most curious numismatic artifacts of Anglo-Saxon England.
786-809 – Caliph Harun al-Rashid rules during the Abbasid golden age, when Islamic gold dinars achieve peak circulation and acceptance. Gold flows from Africa through trans-Saharan trade routes to North African mints.
793-794 – Charlemagne carries out major currency reform, establishing the Carolingian monetary system. Charlemagne’s monetary reforms dominate European coinage, with gold virtually disappearing from Western European minting for nearly five centuries.
ca. 800 – An Arab merchant’s manual recommends Byzantine gold solidi as the safest currency for long-distance trade, noting they can be used “from the lands of the Franks to China” without need for assay or verification, demonstrating the solidus’s unmatched international reputation spanning three continents.
813-840 – Louis the Pious (Charlemagne’s son) issues extremely rare Carolingian gold solidi, among the last Byzantine-style gold coins struck in the West. These ceremonial pieces likely served diplomatic and prestige functions rather than circulating as regular currency.
827-902 – Aghlabid dynasty in Tunisia strikes high-quality gold dinars and begins the Muslim conquest of Sicily, bringing Islamic gold coinage to the island. Sicily becomes a crucial intersection point between Byzantine, Islamic, and Western European monetary systems.
867-886 – Byzantine Emperor Basil I, founder of the Macedonian dynasty, restores some imperial power and maintains the integrity of the gold nomisma. His reign represents the beginning of Byzantium’s middle Byzantine economic revival.
909-1171 – The Fatimid Caliphate, ruling from Tunisia and later Egypt, produces exceptionally high-quality gold dinars known for their distinctive “red gold” purity (approaching 99%). These become the most widespread and trusted trade coins of the Mediterranean, rivaling and eventually surpassing Byzantine gold in commercial importance.
917 – Byzantine Empress Zoe Karbonopsina reportedly offers the Bulgarian ruler Simeon I an enormous bribe of Byzantine gold solidi to spare Constantinople from siege. Though the bribe fails and Simeon besieges the city anyway, the incident demonstrates how gold served as both diplomatic tool and measure of desperation in medieval statecraft.
929-1031 – The Umayyad Caliphate of Córdoba in Spain reaches its zenith under Abd al-Rahman III and his successors, producing abundant gold dinars from trans-Saharan African gold. Córdoba’s mints rival those of Baghdad and Cairo in output and quality.
945-1055 – The Buyid dynasty controls Baghdad and much of Persia, maintaining gold dinar production while the Abbasid caliphs become figureheads. Buyid gold coins demonstrate continued monetary sophistication in the eastern Islamic world.
946-977 – Gisulf I, Prince of Salerno in southern Italy, mints the gold tari closely imitating Fatimid dinars to facilitate Mediterranean trade. This represents early European recognition that Islamic gold coinage has supplanted Byzantine currency as the Mediterranean’s preferred medium of exchange for major transactions.
960s – Byzantine Emperor Nikephoros II Phokas introduces the lighter tetarteron gold coin (about 4.05 grams) alongside the full-weight histamenon nomisma (4.45 grams). This two-tier system reflects economic pressures and creates confusion in the marketplace, contributing to declining confidence in Byzantine gold.
969 – Fatimid general Jawhar al-Siqilli conquers Egypt and immediately begins minting extremely pure “red” gold dinars in Cairo to establish Fatimid monetary authority and demonstrate the new dynasty’s legitimacy and wealth.
973 – Caliph al-Mu’izz arrives in Egypt from Tunisia with reportedly one hundred camel-loads of gold bars to establish Fatimid currency dominance in their new Egyptian capital. This massive transfer of bullion enables the Fatimids to flood the market with high-quality dinars and displace competing currencies.
976-1025 – Byzantine Emperor Basil II “Bulgar-Slayer” presides over Byzantium’s final golden age, with the empire controlling substantial territory and maintaining gold nomisma quality. His reign represents the last period of full Byzantine monetary integrity before 11th-century debasement begins.
1023 – Spanish Jewish banker Bonnom produces gold mancusos for Ramon Berenguer I, Count of Barcelona, imitating Islamic dinars. These coins reflect the economic reality that Islamic gold currency is the accepted standard for Mediterranean trade, even among Christian rulers.
1026-1031 – The collapse of the Umayyad Caliphate of Córdoba into competing taifa kingdoms disrupts Spanish gold coinage, though the taifa states continue producing gold dinars, often of reduced weight and quality.
1028-1034 – Byzantine Emperor Romanos III Argyros begins the gradual debasement of the gold nomisma/solidus, reducing its fineness from the traditional 24 carats that had been maintained for seven centuries. This marks the beginning of a catastrophic century-long decline in Byzantine gold currency.
1031-1147 – The Taifa kingdoms of Islamic Spain continue gold coinage, with each petty kingdom minting its own dinars. The fragmentation of political authority leads to variable gold standards and quality.
1034-1041 – Byzantine Emperor Michael IV the Paphlagonian, a former moneychanger before his unexpected rise to imperial power, takes the unprecedented step of significantly debasing the gold solidus. His background in currency exchange may have influenced his willingness to break with centuries of monetary tradition.
1042-1055 – Emperor Constantine IX Monomachos introduces the scyphate (cup-shaped or concave) form for Byzantine gold coins. The exact reason for this distinctive shape remains debated—theories include easier stacking, fraud prevention, or purely aesthetic considerations. The scyphate form becomes characteristic of later Byzantine coinage.
1043 – A contemporary observer notes that debased Byzantine gold nomismata are being rejected by Italian merchants in Constantinople’s markets, who begin demanding payment only in older, full-weight coins. This marks the beginning of Gresham’s Law in action: “bad money drives out good,” as people hoard quality coins and spend debased ones.
1048-1077 – Fatimid Caliph al-Mustansir adopts the elegant three-circle coin type, maintaining the Fatimid tradition of high gold quality even as Byzantine coinage deteriorates. His long reign sees Fatimid dinars reach their peak of international acceptance.
1061-1091 – Norman conquest of Sicily from Muslim rulers establishes a unique trilingual, tri-cultural state where Byzantine, Islamic, and Western European monetary systems coexist. Norman rulers issue gold tari modeled on Islamic dinars alongside Byzantine-style coins.
1071 – Byzantine defeat at the Battle of Manzikert by Seljuk Turks results in loss of most of Anatolia, drastically reducing imperial tax revenues and gold supplies. This military catastrophe accelerates the monetary crisis already beginning under previous emperors.
1071-1078 – The purity of Byzantine gold coins drops precipitously to approximately 14 carats (58% gold, 42% base metal) under Emperor Michael VII Doukas. This dramatic debasement undermines confidence in Byzantine currency and reflects the empire’s severe financial crisis following the disastrous Battle of Manzikert (1071) and subsequent loss of Anatolia.
1078-1081 – Gold purity falls further to approximately 8 carats (33% gold, 67% base metal) under Emperor Nikephoros III Botaneiates, reducing the nomisma to barely one-third gold content. The Byzantine gold currency approaches complete collapse.
1081-1092 – Byzantine gold coins range from 0 to 8 carats during the first eleven years of Alexios I Komnenos’s reign, as the new emperor struggles to stabilize the empire militarily and economically. Some issues are essentially copper coins with gold wash, representing the nadir of Byzantine monetary credibility.
1085-1147 – Almoravid dynasty controls Morocco, Algeria, and southern Spain, producing high-quality gold dinars from West African gold supplies. Almoravid control of trans-Saharan trade routes gives them access to abundant Saharan and sub-Saharan gold.
1092 – Emperor Alexios I Komnenos enacts comprehensive monetary reform, replacing the debased solidus/nomisma with the hyperpyron (“super-refined”) at 20.5 carats fine gold (approximately 85% pure). While not achieving the purity of the ancient solidus, the hyperpyron restores significant value and confidence to Byzantine gold coinage. The reform establishes a new three-metal system with gold hyperpyra, electrum (gold-silver alloy) trachea, and billon trachea in fixed ratios.
1095 – Pope Urban II promises spiritual rewards and material plunder to those joining the First Crusade. The subsequent looting of wealthy Byzantine and Islamic cities floods Western Europe with gold coins, jewelry, and precious objects, providing many knights their first direct contact with substantial quantities of gold.
1096-1099 – The First Crusade brings tens of thousands of Western European knights and soldiers into direct contact with Byzantine and Islamic gold coinage systems, exposing them to monetary sophistication far beyond their native economies. Crusaders marvel at the wealth circulating in gold in the Eastern Mediterranean.
1099 – Crusaders capture Jerusalem and encounter sophisticated Islamic and Byzantine monetary systems based on gold currency. The Latin Kingdom of Jerusalem subsequently begins minting gold bezants (dinars) copying Islamic models to facilitate trade and taxation in their new territories.
1100-1200 – During the 12th century, approximately 60% of gold circulating in Europe originates from West African sources, transported north across the Sahara through Sijilmasa and other trading centers. Mali and Ghana control crucial gold-producing regions in Bambuk and Bure.
1118-1143 – Byzantine Emperor John II Komnenos maintains his father Alexios’s monetary reforms, keeping the hyperpyron at approximately 20.5 carats. His prudent fiscal management sustains Byzantine gold’s restored credibility.
1123 – Baldwin II of Jerusalem is captured by Muslim forces and ransomed for the enormous sum of 80,000 gold pieces (likely bezants/dinars), demonstrating gold’s role in medieval diplomacy and the extreme value placed on royal captives. The ransom nearly bankrupts the Latin Kingdom.
1130-1154 – Roger II of Sicily creates a sophisticated multi-cultural kingdom where gold tari (based on Fatimid dinars), Byzantine hyperpyra, and later Western gold coins circulate simultaneously. Norman Sicily becomes a crucial monetary crossroads.
1142 – Almoravid gold dinar issued by Tashfin ibn ‘Ali in Spain signals the Iberian Muslim rulers’ assertion of independence from the Abbasid Caliphate in Baghdad. By controlling their own currency, the Almoravids claim sovereignty and religious authority in their domains.
1147-1269 – Almohad dynasty replaces the Almoravids in North Africa and Spain, continuing gold dinar production with distinctive square-shaped coins. Almohad control of western trans-Saharan trade routes maintains gold flow from West Africa.
1171 – Compensation of 108,000 hyperpyra (approximately 1,500 pounds or 480 kilograms of gold) agreed between the Byzantine Empire and Venice for Venetian losses following Emperor Manuel I’s arrest of Venetian merchants in Constantinople. This incident severely damages Byzantine-Venetian relations and demonstrates the scale of Venetian commercial interests in the Byzantine capital. The same year, the Fatimid Caliphate ends when Saladin establishes the Ayyubid dynasty in Egypt.
1171-1250 – Ayyubid dynasty in Egypt and Syria maintains gold dinar production, continuing the monetary traditions established by the Fatimids. Ayyubid gold finances resistance to the Crusades.
1187 – Saladin captures Jerusalem from the Crusaders, disrupting European access to Eastern gold trade routes and ending nearly a century of Latin Christian control over the holy city. The fall of Jerusalem shocks Western Europe and triggers the Third Crusade.
1189-1192 – The Third Crusade brings massive gold expenditures from England, France, and the Holy Roman Empire. Richard I of England and Philip II of France transport enormous quantities of gold to finance their armies in the Holy Land.
1200 – Rum Seljuk Turks in Anatolia issue gold dinars depicting Turkish cavalrymen, blending traditional Islamic monetary practice with figural imagery reflecting Central Asian artistic traditions. These coins represent the cultural synthesis occurring in Anatolia between Turkish, Byzantine, and Islamic elements.
1202 – During preparations for the Fourth Crusade, Venice agrees to transport crusader armies for 85,000 marks of silver, equivalent to approximately twice the annual revenue of the Kingdom of France. When crusaders cannot pay, Venice redirects the crusade to sack Constantinople—whose gold treasures more than compensate the debt, making Venice spectacularly wealthy.
1204 – The Fourth Crusade diverts from its intended target of Egypt and instead sacks Constantinople, the greatest Christian city, dispersing Byzantine gold treasures, relics, and art across Western Europe. This catastrophe permanently weakens the Byzantine Empire and floods Europe with gold objects, including the famous horses of St. Mark’s in Venice. The Empire of Nicaea continues Byzantine traditions in exile.
1204-1261 – The Latin Empire of Constantinople issues gold hyperpyra imitating Byzantine types, but with reduced quality and weight. Meanwhile, the Byzantine Empire in exile at Nicaea also strikes gold hyperpyra, gradually debasing them from 20.5 to 18 carats.
1212-1250 – Frederick II, Holy Roman Emperor and King of Sicily, issues gold augustales featuring classical Roman-style imagery. These beautiful coins represent Frederick’s attempt to revive Roman imperial grandeur and establish an independent gold currency in his southern Italian kingdom.
1218-1221 – The Fifth Crusade targets Egypt, attempting to strike at the Islamic world’s economic heart. Though militarily unsuccessful, the crusade demonstrates European understanding that Egyptian gold wealth is key to Muslim power.
1229 – Holy Roman Emperor Frederick II negotiates the temporary return of Jerusalem through diplomacy with Egyptian Sultan al-Kamil rather than military conquest. This peaceful arrangement proves short-lived and demonstrates that European access to Eastern gold markets depends on negotiation rather than force.
1230-1492 – The Nasrid Kingdom of Granada, last Muslim state in Iberia, continues producing gold dinars from African gold, maintaining Islamic monetary traditions in Spain until the Catholic reconquest.
1235 – The Holy Roman Emperor Frederick II mints his gold augustales showing himself wearing a Roman laurel wreath in pure classical style. Islamic rulers are so impressed by the coin’s artistic quality that some mistake it for ancient Roman coinage, believing Frederick has discovered a cache of Julius Caesar’s gold.
1236-1492 – Christian Spanish kingdoms gradually conquer Muslim territories during the Reconquista, gaining control of cities with established mints and access to African gold trade. Castile and Aragon begin developing their own gold coinages.
1244 – Khwarazmian forces, displaced by Mongol invasions, capture Jerusalem and definitively end significant European control over Eastern Mediterranean gold trade routes. The Latin Kingdom of Jerusalem retreats to coastal strongholds, losing access to interior trade networks.
1248-1254 – Louis IX of France (St. Louis) leads the Seventh Crusade to Egypt, financed with massive gold expenditures. His capture and ransom further demonstrates gold’s central role in Crusader warfare and diplomacy.
1250 – European gold circulation remains extremely limited outside Italy and Spain, with goldsmiths constantly recycling existing coins, jewelry, and ecclesiastical objects to obtain precious metal. The scarcity of gold makes it a luxury commodity reserved for the wealthy and powerful.
1250-1517 – Mamluk Sultanate of Egypt and Syria becomes the Mediterranean’s dominant Islamic power, producing abundant gold dinars from African gold trade. Mamluk gold finances their successful resistance to Mongol invasions and Crusader attacks.
1252 – Florence mints the first gold florin weighing 3.5 grams of 24-carat gold (nominally pure/fine gold), revolutionizing European commerce. The florin is the first European gold coin struck in sufficient quantities since the 8th century to function as regular trade currency rather than merely a prestige or ceremonial object. The coin features Florence’s lily (fleur-de-lis) on the obverse and St. John the Baptist on the reverse. Genoa simultaneously introduces the gold genovino at similar specifications to the florin, competing with Florence for monetary dominance in Mediterranean trade. However, the genovino never achieves the international acceptance of the Florentine florin.
1257 – England issues its first gold penny under Henry III, designed primarily for royal alms-giving and religious charitable donations rather than regular commerce. The coin’s impractical denomination (worth 20 pence) and gold ratio problems lead to its quick withdrawal. Only eight examples survive today.
1258 – Mongol conquest of Baghdad ends the Abbasid Caliphate and disrupts traditional gold trade routes. However, Mongol rulers quickly adopt local monetary systems and continue gold dinar production in their territories.
1259-1282 – Michael VIII Palaiologos recaptures Constantinople and restores the Byzantine Empire, but continues debasing the hyperpyron to approximately 15 carats as the empire lacks resources to restore previous gold standards.
1260-1277 – Baybars, Mamluk Sultan of Egypt, defeats Mongols and Crusaders while maintaining strong gold dinar production. Mamluk Egypt becomes the Mediterranean’s gold trading hub.
1266 – France issues the gold écu (shield) under Louis IX (St. Louis) as part of major monetary reform. The écu features royal heraldic imagery and represents French royal ambitions to establish a stable gold currency to rival Italian gold coins.
1280-1337 – Mansa Musa rules the Mali Empire (dates approximate—his birth and exact accession are uncertain), controlling vast West African gold resources in Bambuk, Bure, and other gold-producing regions. Mali becomes the world’s largest gold producer, supplying 60% or more of Europe’s gold through trans-Saharan trade.
1282 – Byzantine Emperor Michael VIII Palaiologos backs the Sicilian Vespers rebellion against French Angevin rule in Sicily, further debasing the hyperpyron to finance this intervention. The gold content falls to approximately 15 carats.
1282-1328 – Byzantine Emperor Andronikos II Palaiologos continues debasing the hyperpyron to approximately 12 carats as civil wars and territorial losses reduce imperial revenues. The hyperpyron’s declining value accelerates preference for Italian gold coins in Byzantine territories.
1284 – Venice introduces the gold ducat weighing 3.545 grams of 99.47% pure gold (the highest purity achievable through medieval cupellation techniques), establishing a rival to the Florentine florin. The ducat’s slightly higher weight and purity, combined with Venice’s vast maritime trade network, eventually makes it the Mediterranean’s dominant trade coin. The obverse shows the Doge receiving a banner from St. Mark; the reverse depicts Christ standing in a mandorla (almond-shaped frame) surrounded by stars. When Venice introduces the ducat, the Great Council decrees death penalty for mint workers who debase the coinage. This draconian law, combined with rigorous quality control, maintains the ducat’s purity for over 500 years—an unprecedented achievement in monetary history that makes the Venetian ducat more trusted than signed contracts.
1290 – King Edward I of England expels all Jews from the kingdom, partly to seize their gold and cancel debts. The expelled Jewish financiers take their expertise to France and Italian city-states, inadvertently strengthening Florence and Venice’s dominance in international gold trade and banking.
1291 – Fall of Acre eliminates the last major Crusader stronghold in the Holy Land, ending direct European military presence and forcing adaptation to Islamic-controlled gold trade networks.
1294-1303 – Pope Boniface VIII issues gold florins from the papal mint, acknowledging Florence’s monetary leadership. The papacy’s adoption of Florentine standards demonstrates the florin’s dominance in Italian commerce.
1300-1500 – Hungarian gold mines, particularly in Kremnica (Körmöcbánya) in modern Slovakia and other locations in the Carpathian Mountains, produce approximately 450,000-500,000 kilograms of gold during this two-century period, with annual output reaching approximately 1,400-2,250 kilograms. From the 1330s until the Spanish conquest of the Americas in the 1490s, this represented approximately 30% of world gold production. Hungary becomes medieval Europe’s primary indigenous gold source before New World discoveries.
1307-1332 – Mansa Musa’s reign over Mali Empire brings West African gold production to its medieval peak. Mali controls Timbuktu, Gao, and Djenne, key cities connecting gold-producing regions to trans-Saharan trade routes.
1311 – Charles I (Károly Róbert) of Hungary begins systematic gold coinage exploiting ancient Roman gold mines after consolidating power following the assassination of his rival Amadeus Aba. Hungarian gold florins, initially called “floreni” after the Florentine model, became known as “forint” and achieved wide international acceptance.
1317 – A violent conflict erupts in Florence between rival banking families over control of gold exchange rates. The violence becomes so severe that armed guards must protect the money changers’ tables on the Ponte Vecchio bridge, establishing the tradition of goldsmiths’ shops on Florentine bridges.
1324 – Mansa Musa’s legendary pilgrimage to Mecca passes through Cairo, where his extravagant spending and gift-giving floods the Egyptian gold market. Contemporary Arab chroniclers report that his caravan included 60,000 people, including 12,000 slaves, along with 80-100 camels carrying substantial quantities of gold. His distribution of gold caused approximately 20-25% devaluation of the gold dinar in Cairo, disrupting the Egyptian economy for approximately 12 years. Al-Umari, visiting Cairo 12 years later, found residents still discussing Musa’s unprecedented generosity.
1327-1377 – Edward III of England issues various gold denominations attempting to establish stable English gold coinage. His noble and its derivatives become England’s standard gold coins.
1337-1453 – The Hundred Years’ War between England and France creates massive demand for gold to finance armies, driving both kingdoms to develop more sophisticated gold coinages and seek new bullion sources.
1343 – After the collapse of major Florentine banking houses (Bardi and Peruzzi) due to Edward III of England’s default on massive war loans, approximately 300 Florentine families are bankrupted overnight. The crisis temporarily disrupts gold florin production and sends shockwaves through European financial markets, demonstrating the interconnected nature of medieval international finance.
1344 – England issues the gold leopard (formally called a “double florin”) worth 72 pence (6 shillings), beginning England’s first sustained gold coinage program. The coin features Edward III enthroned with two leopards. However, gold ratio problems lead to its quick replacement by the noble in the same year.
1347-1354 – Byzantine civil war between John V Palaiologos and John VI Kantakouzenos further bankrupts the empire. The last Byzantine gold hyperpyra are struck during this joint reign, ending over a millennium of continuous Roman/Byzantine gold coinage tradition.
1348-1350 – The Black Death devastates Europe and the Mediterranean, disrupting trade networks and gold circulation. Population losses reduce demand for coinage temporarily but eventually concentrate wealth and stimulate economic recovery.
1350-1439 – The Roman Senate (revived as a municipal government in medieval Rome) strikes gold zecchini closely imitating Venetian ducat designs, acknowledging Venice’s monetary supremacy even in the papacy’s own city.
1350s – Byzantine hyperpyron ceases regular circulation as a physical coin, remaining only as an abstract money of account for bookkeeping. Actual transactions increasingly use Venetian ducats, Genoese coins, or debased Byzantine currency. The disappearance of Byzantine gold coinage marks the effective end of Roman monetary tradition stretching back to Constantine I’s solidus (310 CE).
1354 – The Rhenish florin (gulden) is formally established through monetary convention among Rhine valley cities and principalities. Initially matching the Florentine florin at approximately 3.43 grams of gold, the Rhenish florin suffers gradual debasement, declining to 2.76 grams by 1419 as authorities extract profit through repeated reductions in weight and fineness.
1356 – The Golden Bull of Emperor Charles IV, the constitutional document of the Holy Roman Empire, specifies that electors’ payments and ceremonial gifts must be made in gold coins of specific weights. The document includes detailed descriptions of proper gold coinage, reflecting how monetary standards become inseparable from political legitimacy.
1360 – The Treaty of Brétigny between England and France requires France to pay 3 million gold écus (approximately 10 tons of gold) as ransom for King John II of France. The sum is so enormous that France must levy special taxes and melt down church gold to raise it, and full payment takes years, impoverishing the French kingdom.
1369 – Tamerlane (Timur) begins his conquests in Central Asia, eventually controlling territories from Turkey to India. His empire maintains gold coinage traditions inherited from previous Islamic dynasties.
1375 – The Catalan Atlas, produced by Jewish cartographer Abraham Cresques on Majorca for the French crown, depicts Mansa Musa seated on a throne in West Africa holding a gold nugget and scepter. This influential map spreads knowledge of West African gold wealth to European royal courts and inspires Portuguese interest in accessing African gold sources directly by sea.
1380-1422 – French King Charles VI issues gold écus d’or during the Hundred Years’ War to finance military campaigns. The coin features the French royal shield and maintains relatively good quality despite wartime pressures, helping establish French gold currency credibility.
1396 – Battle of Nicopolis sees Ottoman victory over European crusaders, demonstrating Ottoman military superiority. Ottomans begin developing their own gold coinage systems, initially imitating Mamluk and Venetian models.
1401 – The Byzantine Emperor Manuel II Palaiologos embarks on a humiliating journey through Western Europe personally begging for gold subsidies to save Constantinople from Ottoman conquest. European kings treat him with ceremonial respect but offer minimal gold assistance, preferring to let the Byzantine Empire collapse as a buffer against Ottoman expansion.
1402-1405 – Tamerlane defeats the Ottoman Sultan Bayezid I at Ankara, temporarily disrupting Ottoman expansion. Timurid gold coins circulate across Persia and Central Asia.
1415 – Portuguese forces capture Ceuta in Morocco, initiating Portugal’s systematic exploration and exploitation of West African coastal gold resources. This marks the beginning of European attempts to bypass trans-Saharan trade controlled by Muslim merchants and access African gold directly.
1420 – Gold flows from Venice to the Mamluk Sultanate through the Fondaco dei Tedeschi (German trading house in Venice), which serves as a hub for Central European gold flowing to Egypt in exchange for spices, textiles, and other luxury goods from the Indian Ocean trade network.
1422 – A Chinese official visiting Hormuz in the Persian Gulf reports seeing bazaars where “gold dinars are piled up like firewood,” describing the enormous quantities of gold flowing through Indian Ocean trade routes between Africa, the Middle East, and Asia. This wealth rarely reaches Europe, contributing to European gold scarcity.
1429 – The Mamluk Sultan Barsbay attempts to monopolize all pepper trade through Egypt, demanding payment exclusively in gold dinars. This forces European merchants to ship even more gold eastward, accelerating the late medieval bullion shortage and motivating Portuguese exploration for direct African gold access.
1432 – The Papal mint in Rome begins issuing ducats following Venetian standards alongside traditional florins, acknowledging that multiple gold currencies circulate in Italy. The papacy’s adoption of the ducat standard demonstrates Venice’s complete monetary victory over Florence.
1434-1494 – The Medici family dominates Florence, using the city’s banking network and the florin’s international acceptance to become Europe’s premier financiers. Medici banks operate branches throughout Europe, facilitating gold flows and international payments.
1435 – The Florentine florin is restored to its original full weight of 3.5 grams after minor 14th-century reductions caused by fiscal pressures during wars with Milan and Pisa. Florence’s commitment to maintaining gold standard demonstrates the city’s recognition that monetary credibility underpins its commercial dominance.
1441 – Portuguese reach the gold-producing regions of West Africa directly, establishing trading posts. This begins Europe’s direct access to African gold sources, bypassing Muslim intermediaries.
1442-1458 – Alfonso V of Aragon conquers Naples and southern Italy, establishing a Spanish dynasty that issues gold ducats modeled on Venetian types, further spreading ducat standards.
1447 – Pope Nicholas V authorizes Portugal to conquer and enslave non-Christians in West Africa, explicitly linking the papal blessing to Portuguese access to African gold mines. This makes the papacy complicit in the African slave trade in exchange for Portuguese gold flowing to Rome.
1450 – A Florentine merchant’s account book records that a single gold florin can purchase enough grain to feed a family of four for one month, or pay a skilled mason’s wages for one week, providing a glimpse of gold’s immense purchasing power in daily medieval life.
1453 – Ottoman Sultan Mehmed II conquers Constantinople, definitively ending the Byzantine Empire and its millennium-long gold currency tradition stretching back to Constantine the Great’s solidus. The fall of Constantinople sends shockwaves through Christian Europe and marks the final chapter in Roman monetary history. The Ottomans subsequently develop their own gold coinage, the sultani, based on Venetian ducats.
1455 – The printing of the Gutenberg Bible requires investors to advance approximately 300 gold florins—equivalent to three years’ wages for a craftsman. Johannes Gutenberg never fully repays his debts and loses control of his printing press, despite revolutionizing European culture.
1455-1485 – Wars of the Roses in England create demand for gold to finance rival claimants to the throne. Both Yorkist and Lancastrian factions issue gold nobles and related denominations.
1457-1464 – The Great Bullion Famine strikes Europe, causing severe shortage of precious metals for coinage. Increased European trade with Asia drains gold eastward; Atlantic African gold sources haven’t yet been fully developed; and European mines face declining yields. The shortage causes severe economic disruption and stimulates search for new bullion sources.
1465 – England creates the gold rose noble worth 120 pence (10 shillings) featuring a rose on the ship design, and the gold angel worth 80 pence showing Archangel Michael slaying a dragon. The angel becomes England’s standard gold coin for over a century, circulating widely in European trade.
1468 – Charles the Bold, Duke of Burgundy, commissions a 570-page illuminated manuscript paying the artists 800 gold florins. A single page thus costs approximately 1.5 florins—more than a week’s wages for the skilled artisans creating it, demonstrating how gold sustained medieval artistic patronage.
1471 – Portuguese establish São Jorge da Mina (Elmina Castle) on the Gold Coast of West Africa, securing direct access to West African gold. This fort becomes the center of Portuguese gold trade, handling hundreds of kilograms annually.
1476 – A Venetian merchant’s letter describes seeing Ottoman Sultan Mehmed II’s treasury containing “gold coins stacked higher than a man’s head in rooms the size of churches,” reflecting how Ottoman conquests concentrated vast quantities of Byzantine, Islamic, and Eastern European gold in Constantinople.
1478 – Ottoman Sultan Mehmed II introduces the gold sultani (also called altun), modeled on the Venetian ducat, establishing Ottoman gold coinage that will continue until the 20th century.
1479 – Treaty of Alcáçovas between Portugal and Spain divides African trade rights, with Portugal securing exclusive access to Gold Coast trade. This diplomatic agreement ensures Portuguese control of African gold supplies.
1489 – England mints its first gold sovereign under Henry VII, the first English £1 (20 shilling) gold coin. The large, impressive coin features a highly detailed portrait of the king enthroned on the obverse. The sovereign becomes England’s premier gold coin and is revived in 1817, continuing to present day.
1491 – On the eve of Columbus’s departure, the Spanish monarchs Ferdinand and Isabella’s entire annual revenue is approximately 5 million maravedís—roughly equivalent to 12,500 gold ducats, or about 44 kilograms of gold. Within decades, Spanish America will produce this quantity monthly, revolutionizing the global economy.
1500s – Portuguese traders handle approximately 400-550 kilograms of West African gold annually through their coastal forts and trading posts, particularly São Jorge da Mina (Elmina) on the Gold Coast (modern Ghana). This gold, brought from interior sources by African merchants, enriches Portugal and helps finance the Portuguese maritime empire’s expansion into Asia. By 1500, the stage is set for the influx of American gold that will revolutionize European and world monetary systems in the 16th century.

Final Thoughts

The quest for gold drove exploration, sparked conflicts, and ultimately connected diverse cultures in ways that prefigured our modern global economy. As medieval rulers debased their currencies and merchants developed complex exchange systems, they established patterns of international finance that resonate today.

The Middle Ages thus transformed gold from ancient treasure into the foundation of international commerce, leaving a golden legacy that would shape the modern world.
