TheByzantine economy was among the most robust economies in the Mediterranean and the world for many centuries.^[1][2]Constantinople was a prime hub in a trading network that at various times extended across nearly all ofEurasia and North Africa. It could be argued that up until the 7th century, theEastern Roman Empire had the most powerful economy in the world.^[a] The Arab conquests, however, would represent a substantial reversal of fortunes contributing to a period of decline and stagnation. The Byzantine state restructured its administrative and fiscal systems, introducing thetheme system, which organized land and military service in a way that ensured both local defense and agricultural productivity. Rural life revived as new lands were brought under cultivation, and local economies became more self-sufficient, reducing dependence on long-distance trade that had been curtailed by the loss of eastern territories. By the 9th and 10th centuries, the empire experienced a notable resurgence: agricultural output increased, population levels rose, and the circulation of coinage expanded once again. However, by the 12th and 13th centuries, the economic balance began to shift. Western maritime republics such as Venice and Genoa gradually overtook Byzantine merchants, largely due to the tax exemptions and trading privileges granted to them under theKomnenian emperors. This process accelerated after theFourth Crusade and the establishment of the Latin Empire, during which Venetian traders gained control over key ports and commercial networks once held by the Byzantines. The Byzantines continued to face economic challenges during thePalaiologan era until itsfall in 1453.

One of the economic foundations of the empire was trade. The state strictly controlled both the internal and the international trade. Constantinople remained the single most important commercial centre of Europe for much of theMedieval era, which it held until theRepublic of Venice slowly began to overtake Byzantine merchants in trade; first through tax exemption under theKomnenoi, then under theLatin Empire.

From 4th to end of 6th century the eastern part of Roman Empire had demographic, economic andagricultural expansion. The climate was opportune for farming. Even in marginal regions rural settlements flourished.^[3] The Arab conquests of the 7th century and subsequent territorial losses disrupted traditional agricultural regions, particularly in Egypt and the Levant, leading to a decline in surplus production and forcing the empire to rely more on Anatolia and the Balkans. During the middle Byzantine period, agricultural recovery occurred alongside political stabilization. Reforms encouraged small-scale farming, irrigation, and improved crop techniques. Large estates still existed, but many peasants gained more autonomy, and the production of olive oil, wine, and cereals expanded to meet both domestic and trade demands.

The 12th century saw the development oftilling andmilling technologies in the West, but there is less evidence for similar Byzantine innovation. Western advances like thewindmill were adopted by the Byzantines, but, unlike the West,Arabic numerals were not yet implemented for double-entry book-keeping. There are illustrations of agricultural implements fromilluminated medieval manuscripts ofHesiod'sWorks and Days including thewheel,mortar,pestle,mallet and some parts forcarts andsoleard plough, but, even centuries later, neither the plough nor wheeled cart were widely in use, possibly because of the nature of thePontic terrain.^[4]

In the late Byzantine period (13th–15th centuries), after the Latin occupation and territorial fragmentation, agriculture faced new challenges. Estates were often overtaxed, and warfare or raids disrupted rural life. Despite this, certain regions, particularly in western Anatolia and parts of Greece, remained productive, supplying local markets and urban centers. Throughout Byzantine history, agriculture remained the foundation of the empire’s economy, adapting to political and environmental pressures while sustaining urban populations, the military, and long-distance trade.

The Eastern Roman economy suffered less from the Barbarian raids that plagued theWestern Roman Empire. UnderDiocletian's reign, theEastern Roman Empire's annual revenue was at 9,400,000solidi, out of a total of 18,000,000solidi for the entire Roman Empire.^[5] These estimates can be compared to the AD 150 annual revenue of 14,500,000solidi and the AD 215 of 22,000,000solidi. By the end ofMarcian's reign, the annual revenue for the Eastern empire was 7,800,000solidi, thus allowing him to amass about 100,000pounds/45tonnes of gold or 7,200,000solidi for the imperial treasury.^[5] Warren Treadgold estimates that during the period from Diocletian to Marcian, the Eastern Empire's population and agriculture declined a bit, but not much. Actually, the few preserved figures show that the largest eastern cities grew somewhat between the 3rd and 5th centuries.^[6] By Marcian's reign the Eastern Empire's difficulties seem to have been easing, and the population had probably begun growing for the first time in centuries.^[7] The period encompassing Anastasius' and the first half of Justinian's reign saw further economic expansion, with state revenues increasing and a decline in land abandonment and complaints of overtaxation. Such growth would also explain the other signs of public and private prosperity at the time, including Justinian's ability to undertake so many costly activities at once.^[8]

The wealth of Constantinople can be seen by howJustin I used 3,700 pounds/1.66 tonnes of gold just for celebrating his own consulship. By the end of his reign,Anastasius I had managed to collect for the treasury an amount of 23,000,000solidi or 320,000 pounds/144 tonnes of gold. At the start ofJustinian I's reign, the Emperor had inherited a surplus 28,800,000 from Anastasius I and Justin I.^[9] Before Justinian I's reconquests the state had an annual revenue of 5,000,000solidi, which further increased after his reconquests in 550.^[9] At the height of Justinian's reign in 540 (before the plague), the state revenues of the Byzantine Empire were estimated to be as high as 11.3 million solidi.^[10] Due to the empire's affluence, Justinian was able to undertake costly building projects. The church of the Holy Apostles in Constantinople and the church of Saint John at Ephesus likely cost 1 million solidi each,^[11] and the Perpetual Peace with Persia cost 792,000 solidi.^[11] Nevertheless, Justinian I had little money left towards the end of his reign partly because of theJustinian Plague, and theRoman–Persian Wars (Justinian spent large amounts of money in annual subsidies to theSassanian Empire^[12]), as well as his wars of reconquest in Italy and North Africa, all of which greatly strained the royal treasury. In addition to these expenses, the rebuilding ofHagia Sophia cost 20,000 pounds/9 tonnes of gold.^[13] Subsidies to enemy states were also paid by Justinian's successors:Justin II was forced to pay 80,000 silver coins to theAvars for peace; his wife Sophia paid 45,000solidi toKhosrau I in return for a year's truce,^[14] and thenTiberius II Constantine gave away 7,200 pounds of gold each year for four years, on top of giving away the treasure of Narses and 1,000 centenaria to the poor (allegedly worth 100,000 pounds of gold). The East Roman Empire's aristocratic language ofLatin began to erode and give way to the native language ofGreek starting during theRoman-Persian Great War of 602-628, thesolidus (plural:solidi) would begin to also be known by its Greek name, thenomisma (plural:nomismata).^[15] For all of the financial difficulties the empire faced, the government kept its revenues at a remarkably high level under the circumstances and was able to pay their soldiers. The government would have been functioning at a high level of efficiency to handle its fiscal problems well and avoid financial collapse and bankruptcy.^[16]

TheByzantine-Arab Wars reduced the territory of the Empire to a third in the 7th century and the economy slumped; in 780 the Byzantine Empire's revenues were reduced to only 1,800,000nomismata. From the 8th century onward the Empire's economy improved dramatically. This was a blessing for Byzantium in more than one way; the economy, the administration of gold coinage and the farming of theAnatolian peninsula served to meet the military's constant demands. Since Byzantium was in a constant state of warfare with her neighbours (even if only by raiding) the military required weapons to be manufactured by the bigger cities (such asThessaloniki) whilst the smaller towns were subject to grain, wine and even biscuit requisitions by Imperial officers. Even though the soldiers' pay was minimal, large armies were a considerable strain on Byzantium. But soldiers were paid to serve in the army; they would in time spend the money acquiring their own goods. As a result, the Byzantine economy was self-sufficient, allowing it to thrive in theDark Ages. The success of the Byzantine army was in no small part due to the success of her economy.^[17]

Around 775, theland andhead taxes yielded an estimated 1,600,000nomismata/7.2 tonnes of gold annually for the empire. Commerce during this period slumped, therefore only contributing 200,000nomismata annually. The expenditures of the period were quite large when compared to the annual revenues. Approximately 600,000nomismata went to the payroll of the army annually while other military costs took another 600,000nomismata annually. Supporting theByzantine bureaucracy needed 400,000nomismata. Also, imperial largess cost the treasury 100,000nomismata every year. All of these expenses meant that the Byzantine government had only about 100,000nomismata in surplus revenue each year for treaties, bribes, or gifts.^[18]

Expenses again soared, when a massiveMuslim army invaded the empire in 806, forcingNikephoros I to pay a ransom of 50,000 gold coins and a yearly tribute of 30,000 gold coins.^[19] In order to impress theCaliph of Baghdad,Theophilos distributed 36,000 gold coins to the citizens of Baghdad, and in 838, he was forced to pay 100,000 golddinars to the Caliph. The Byzantine economic recovery in the early 9th century can be seen by the fact that Emperor Theophilos was able to leave 7,000,000nomismata/31.5 tonnes of gold in the imperial treasury for his successor in 842.^[20] After Theophilos' death his wifeTheodora II continued his successful policies and even increased the imperial reserves to 7,848,000nomismata.

Around 850, the land and head taxes yielded an estimated 2,900,000nomismata annually for the empire. Commerce during this period increased dramatically, therefore contributing 400,000nomismata annually. The expenditures of the period were large, but manageable by the treasury. Approximately 1,400,000nomismata went to the payroll of the army annually while other military costs took another 800,000nomismata annually. Supporting the Byzantine bureaucracy needed 500,000nomismata. Also, imperial largess cost the treasury 100,000nomismata every year. All of these expenses meant that the Byzantine government had about 500,000nomismata in surplus revenue each year, much more than in the 8th century.^[18]

Unfortunately under their sonMichael III the reserves dwindled to about 100,000nomismata.^[21] However, under Basil I's prudent economic policies, the state quickly raised 4,300,000nomismata, far more even than the empire's annual revenue of 3,300,000nomismata.^[9]

WhenLiutprand of Cremona was sent as an ambassador to the Byzantine capital in the 940s, he was overwhelmed by the imperial residence, the luxurious meals, and acrobatic entertainment.^[22]

Sviatoslav I was paid 15,000 pounds of gold byNikephoros II to invadeBulgaria in 968.John Tzimiskes received the equivalent to 3,000,000 gold coins from the Muslims of the city of Ecbatana.^[23] By the time ofBasil II's death in 1025, the annual income had increased to 5,900,000 - 7,000,000nomismata, which allowed him to amass a large gold reserve of 14,400,000nomismata (200,000 pounds/90 tonnes of gold) in the treasury for his successor. Even then, Basil II had waived two years' worth of land and hearth taxes, which would have been worth 8 million more nomismata.^[24][25][26] The wealth of the empire at Basil's death was so immense that it impressed the Muslims, such that a late eleventh-century Arab source informs us that “When Basil, son of Romanos, the emperor of Byzantium, died . . . he left ten thousand qintars of gold coins ( 1,000,000 pounds or 72,000,000 gold coins) and jewels worth 54 million dinars.”^[23]Constantine IX was also able to send the Caliph 30 quintars of gold (216,000 nomisma) and 300,000 golddinars.^[27]

Nevertheless, the Byzantine economy went into a long decline until theComnenian Dynasty was able to revive the economy. In the aftermath of theBattle of Manzikert, Alp Arslan at first suggested to EmperorRomanos IV a ransom of 10,000,000 gold coins, but later reduced it to 1,500,000 gold coins with a further 360,000 gold coins annually.^[28]

In exchange for an alliance,Alexios I sent 360,000 gold coins to EmperorHenry IV.^[29] The wealth of the empire under the Comnenians can be seen by how EmperorManuel I was able to ransom some Latin prisoners from the Muslims for 100,000 dinars, then 150,000 dinars forBohemond III in 1165, 120,000 dinars forRaynald of Châtillon, and 150,000 dinars forBaldwin of Ibelin in 1180.^[30] When Manuel became emperor he ordered 2 gold coins to be given to every householder in Constantinople and 200 pounds of gold (including 200 silver coins annually) to be given to theEastern Orthodox Church.^[31] When his nieceTheodora married KingBaldwin III ofJerusalem in 1157, Manuel gave her a dowry of 100,000 gold coins, 10,000 gold coins for marriage expenses, and presents (jewels and silk garments) which were worth 14,000 gold coins total.^[32] The expense of Manuel's involvement in Italy must have cost the treasury a great deal (probably more than 2,160,000hyperpyra or 30,000 pounds of gold).^[33] Then he also promised to pay 5,000 pounds of gold to thePope and theCuria. During his reign, Manuel bought a very rich jewel (for 62,000 silvermarks) which was used during the coronation of the Latin EmperorBaldwin I.^[34] The main source of the state's wealth in the 12th century was thekommerkion, a customs duty levied at Constantinople on all imports and exports, which was stated to have collected 20,000hyperpyra each day.^[35] This, combined with other sources of income, meant the empire's annual revenue was at 5,600,000hyperpyra in 1150.^[36] Under the Komnenian emperors, many exemptions of trade duties were given to the Italian traders, which meant the loss of about 50,000hyperpyra annually.^[36] A Venetian embassy visited Constantinople in 1184 and an agreement was reached that compensation of 1,500 pounds of gold (or 108,000hyperpyra) would be paid for the losses incurred in 1171.^[37] By the end of Manuel I's reign the amount of money used to maintain the Komnenian imperial family is said to be able to maintain an army of 100,000 men.^[38]

After the demise of the Komnenoi, the Byzantine economy declined under the impact of several factors: the mismanagement under the Angeloi, the dismemberment of the Empire after 1204, the successive territorial losses to the Turks (although the strong economic interaction of Byzantine territories with those lost by the Empire continued), and the Italian expansion in the Mediterranean and theBlack Sea.^[39] WhenIsaac II Angelos became Emperor in 1185, a mob broke into the palace and carried off 1,200 pounds of gold, 3,000 pounds of silver, and 20,000 pounds of bronze coins.^[40] In 1195, Holy Roman EmperorHenry VI forced Byzantine EmperorAlexios III Angelos to pay him a tribute of 1,000 pounds of gold (originally 5,000 pounds of gold) and in 1204 Alexios III took 1,000 pounds of gold (or 72,000hyperpyra) when he fled Constantinople, leaving the treasury empty.^[41] Fires ravaged the northern and central sections of the city, resulting in a steady exodus of residents. The sack of Constantinople by Latin crusaders in 1204 was an economic catastrophe. However, even with the empire at its poorest in 1203, Alexios IV managed to pay 440,000 hyperpyra out of 200,000 silver marks (equivalent to 800,000hyperpyra) to the Crusaders.^[42] The official tally of plunder from Constantinople was about 900,000 silver marks, the equivalent of about 3,600,000hyperpyra or 50,000 pounds/22.5 tonnes of gold, although this figure likely does not include the value of the countless icons and books destroyed, ancient statues melted down (some made in Alexander the Great's time), and the destruction of other cultural artifacts.^[42][43] In 1237, Latin EmperorBaldwin II pawned theCrown of Thorns to a Venetian merchant for 13,134 gold coins.^[44]

By the time the Palaiologoi took power, Italian merchants had come to dominate the trade by sea whilst Turkic incursions prevented any success from trade across roads.Michael VIII Palaiologos strove to restore the capital, but lacked the resources to do so. In 1282, Michael VIII was forced to drain the treasury to pay the enormous bribe of 60,000hyperpyra to KingPeter III of Aragon to invade theKingdom of Sicily.^[45] By 1303, the empire's annual revenue dropped to less than 1,800,000hyperpyra, underAndronikos II Palaiologos. In 1321, only with extreme effort was Andonikos II able to raise revenues to 1,000,000hyperpyra.^[46]

The Byzantine economy had declined so much that by 1343, EmpressAnna of Savoy had to pawn the Byzantinecrown jewels for 30,000 Venetian ducats, which was the equivalent of 60,000hyperpyra.^[47] In 1348, Constantinople had an annual revenue of 30,000hyperpyra while across the Golden Horn in the Genoese colony ofGalata, the annual revenue was 200,000hyperpyra. When EmperorJohn VI Kantakouzenos attempted to rebuild the Byzantine navy, he was only able to raise an inadequate 50,000hyperpyra. The only success during this period was when theRepublic of Genoa agreed to pay a war indemnity of 100,000hyperpyra in 1349. When EmperorJohn V Palaiologos was captured byIvan Alexander in 1366, he was forced to pay a ransom of 180,000florins. In 1370, the empire owedVenice, 25,663hyperpyra (of which only 4,500hyperpyra had so far been paid) for damage done to Venetian property.^[48] In February 1424,Manuel II Palaiologos signed an unfavorable peace treaty with the Ottoman Turks, whereby the Byzantine Empire was forced to pay 300,000 silver coins to the Sultan on annual basis. In 1453, the economy of the Genoan quarter in Constantinople had a revenue almost 7 times greater than that of the whole Empire — not even a shadow of its former self.^[49] EmperorConstantine XI owed Venice 17,163hyperpyra when he died in 1453.^[50]

The exact amount of annual income the Byzantine government received, is a matter of considerable debate, due to the scantness and ambiguous nature of the primary sources. The following table contains approximate estimates.

Byzantine coinage formed the backbone of the empire’s economic system and had a stable monetary structure. Following the reforms of EmperorAnastasius I in 498 CE, the Byzantines developed a sophisticated system based on the goldsolidus (ornomisma), which maintained remarkable consistency in weight and purity for over seven centuries. It circulated far beyond the empire’s borders, throughout Europe, the Middle East, and even into Asia, serving effectively as a reserve currency for much of theMiddle Ages in areas likeEurope and theNear East. Merchants and rulers alike used thesolidus as a standard of value and a store of wealth, and its stability underpinned the empire’s extensive trade networks. Even after later debasements and the introduction of thehyperpyron in the 11th century, Byzantine gold coinage remained influential, symbolizing the fiscal strength and far-reaching economic presence of the Byzantine Empire. By the early 14th century, Byzantine coinage had shifted toward Western European influences. In 1304, the empire introduced thebasilikon, a pure silver coin modelled after the Venetian ducat, signalling the decline of the olderKomnenian monetary system. Later, in 1367, thestavraton became the principal coin, a heavy silver piece worth twice the fine metal content of the last hyperpyron. However, by the late 12th and early 13th centuries—especially after the Fourth Crusade in 1204—the fragmentation of Byzantine territory led to the creation of separate regional and feudal currencies, such as those ofTrebizond,Bulgaria, andSerbia.Venetian coins also began circulating widely within the empire, replacing the once-dominant Byzantine currency. This marked a sharp contrast to earlier centuries, when Byzantine coinage had maintained a virtual monopoly within its borders and was widely used beyond them, reflecting the empire’s former political and economic authority.^[61]

During Byzantine history, supervision of the mints belonged to the Emperor; thus the government controlled, to a certain degree, the money supply.^[b][62]

One of the economic foundations of the empire was trade. Constantinople was located on important east-west and north-south trade routes.Trebizond served as an important port in the eastern trade. Exact trading routes varied over the years with wars and the political situation. Byzantine authorities uniformly taxed both imports and exports at ten percent.

Grain andsilk were two of the most important trade commodities for the empire. TheArab invasions ofEgypt and ofSyria in the 7th century harmed Byzantium's trade and affected grain shipments.^[63]

The Byzantine state usedsilk both as a means of payment and in diplomacy. Raw silk was bought from China and made up into finebrocades andcloth-of-gold that commanded high prices through the world. In the mid-sixth century two monks smuggled silk worms out of China into the empire, and subsequently theoverland silk-trade became less important. AfterJustinian I (r. 527–565) the manufacturing and sale of silk became an imperial monopoly, with processing limited to imperial factories, and product sold to authorized buyers.[64]

Textiles were exported to Egypt, and they also appear in Bulgaria and the West.^[65] The empire had also trading activity throughVenice (as long as Venice formed part of the empire'sExarchate of Ravenna).^[64] In 992 the Emperor Basil II concluded a treaty with theVenetian DogePietro Orseolo II, reducingVenice's custom duties in Constantinople from 30nomismata to 17nomismata in return for the Venetians agreeing to transport Byzantine troops toSouthern Italy in times of war.^[66] During the 11th and 12th centuries Italian traders in the empire operated under privileged conditions, incorporated in treaties and privileges that were granted toAmalfi, Venice,Genoa, andPisa.^[67]

Cities in the Byzantine Empire contained market places, theatres, baths, colonnaded streets, churches, shops, cook shops and workshops as well as other facilities.^[68] Urban life was prosperous,^[69] and there was a vast range of occupations ranging from public and ecclesiastical officials to sausage sellers, barbers and dancers. Prominent among them are merchants and artisans. Manufactures included clothes, linen, leather, shoes, pottery, hardware, glass and purple dye.^[70] People worked gold, stone and marble and produced and sold many food products such as fruits, vegetables, cakes, pastries, bread, fish and drinks. Bankers, carpenters, architects, lawyers, tailors, cleaners, and keepers of shops, taverns and restaurants added to the complement of activities.^[70] As such, cities such as those in Asia Minor flourished.^[71] In most places, the heights of prosperity were reached in the late 5th and early 6th centuries, and the work of Justinian was especially evident in many. However, almost all succumbed to the economic changes and invasions of the 7th century.^[71] The average wage for an unskilled worker in the Byzantine Empire was about 1 nomisma per month or about 10-12 nomisma per year. Skilled workers and the wealthiest workers received considerably more, earning up to 10 and 150 times more respectively.^[1][72]

Agriculture was the main occupation of the empire, and villages and market towns contained the vast majority of the population.^[71] In the cases of Syria and Palestine, well preserved villages and towns reveal a high standard of living and an unexpected degree of wealth, even in remote areas. Nevertheless, rural life was poorer than urban, both materially and culturally. The countryside contained a dense network of prosperous villages, with wheatfields and vineyards, cattle, mules and oxen. Apart from farmers, there were smiths, lime burners and builders as well as teachers, sorcerers, fortune tellers and doctors.^[73] The Byzantines followed a diet characteristic of the medieval Mediterranean world, consisting of grains and legumes, olive oil and wine, dairy goods, fish and various meats, along with fresh produce. Honey served as the main source of sweetness, and poultry supplied both eggs and meat. In regions too cold for olive cultivation, butter took the place of olive oil as the primary fat.^[74]

Mining

The Byzantine Empire inherited the advanced and varied mining practices ofRome, which included extensive mining regions producinggold,silver,copper,iron, and other metals, alongside numerous smaller and even modest-scale operations. Large, state-run mining enterprises functioned alongside privately or collectively leased mines, as well as small-scale mining carried out by peasants as a supplementary source of income. An intricate administrative system oversaw these activities, managing imperial mining operations, imposing specific taxes on land rich in mineral resources, and collecting production dues from miners and others. This bureaucracy ensured that all precious metal output ultimately came under state control. Gold extraction took place in places such as theBalkan territories and along the frontiers ofArmenia. Recent archaeological discoveries have also identified evidence of middle Byzantine mining activity in several locations of northwestern Asia Minor—specifically in the area between theHellespont and theGulf of Adramyttion, near Kinyra on the island ofThasos, and around Peristera. Iron mining operations were likewise conducted in theTaurus Mountains.^[75]

Glassmaking

During the early Byzantine era, the widespread adoption of glass-blowing revolutionized the glass industry, leading to rapid growth in production and craftsmanship. Glass became an essential material in various aspects of daily and religious life, used not only for windows in churches, where it transformed interior lighting, but also for lamps, tableware, and decorative objects. The artistry of glass even influenced the development of certain ceramic styles that sought to imitate its beauty. Archaeological evidence points to several major centers of glass manufacture and distribution, includingEgypt,Palestine, Transjordan,Sardis,Constantinople, and others. Production flourished across both the eastern Mediterranean and parts of Europe, suggesting a vibrant exchange of techniques and styles between these regions, although the exact nature of their economic and technological connections remains uncertain.^[76]

Textiles

The textile industry was a cornerstone of the Byzantine economy and one of the most vital commercial sectors inherited from antiquity. Production took place in both state controlled and privately owned workshops spread across the empire. Among the most renowned imperial manufacturing centers were the linen factories of Scythopolis, the wool-processing mills of Heraclea inThrace,Kyzikos, andCaesarea, amongst others. The Byzantines primarily worked with wool and linen, though hemp also played a significant role in fabric production. Textiles served a wide range of purposes, from garments and household furnishings to wall hangings and carpets, and their creation required great technical skill. Processes such as spinning, weaving, carding, and dyeing required artisans who possessed specialized expertise and training. These crafts not only met domestic needs but also supported long-distance trade, as fine Byzantine textiles were highly prized throughout the Mediterranean and beyond.^[77]

Metalworking

Metalworking was the most important manufacturing sector in the Byzantine Empire, split into work with base metals and precious metals. Artisans usediron,copper,lead, andtin to make everyday items like nails, tools, utensils, keys, clamps, and weapons in both imperial workshops (Sardis, Concordia...etc) and private workshops, sometimes adding leather or precious metals. Weapons and military clothing were highly admired and influenced neighboring peoples. Gold and silver work required wealthy guilds, as the materials were valuable. Church treasuries and imperial courts showed the empire’s wealth, with luxury items combining gold, gems, pearls, and enamel. The state controlled silver through hallmarks and closely regulated gold, which was the main monetary standard. Goldsmiths often handled money-changing and banking, gaining influence over public funds and taxes, especially underJustinian's reign.^[78]

Other crafts

Archaeological and textual evidence points to the prominence ofwoodworking and related crafts in the Byzantine world. These activities encompassed a broad spectrum of skills, includingcarpentry,shipbuilding and others, all of which were essential to both everyday life and large-scale economic production. Likewise, trades connected to the treatment and use of animal hides were well developed. These includedleatherworking,shoemaking, the manufacture of garments, and others. In addition, artisans were well acquainted with working with bone, ivory, and wax, crafting both practical items and detailed decorative objects.^[79]

Money changers held an important role in the urban economy and were prominent in the popular imagination of city life. Numerous texts and images depict them at their tables, equipped with coin scales and accounting registers, performing money-changing and assaying, verifying the weight and fineness of coins used in transactions. Once authenticated, coins were placed in sealed sacks by the money changers.

They operated shops or iron tables in commercial areas, performing relatively straightforward roles, but they were vital in daily life due to the wide value differences between gold, silver, and copper coins, facilitating small change for purchases and gifts. Because their work involved coinage and money circulation, money changers, while engaged in private business, also held a semi-public role, subject to stricter state oversight and required to respond to summonses regarding minting or the collection of older coins for replacement. There were also loans and partnerships in Byzantium that encouraged investment and other projects, which helps to drive economic growth.^[80][81]

The ByzantineGDP per capita has been estimated by theWorld Bank economistBranko Milanovic to range from $680 to $770 in1990 International Dollars at its peak around 1000 (reign ofBasil II).^[82] This corresponds to a range of $1637 to $1853 in today's dollars. The Byzantine population size at the time is estimated to have been between 12 and 18 million.^[83] This would yield a totalGDP somewhere between $20 and $33 billion in today's terms.
