The Seljuk Economy

From the eleventh to the thirteenth centuries, Seljuk rulers drew income and supplies from farms, herds, towns and trade. The Great Seljuk realm centred on Iran and Iraq and at times extended into Central Asia; the separate Sultanate of Rum governed much of Anatolia, the peninsula between the Black Sea and Mediterranean. Their economies linked rural production to cities and political service, but local water, pasture, routes and currencies shaped how that connection worked.

Fields, water and pasture

Farm work followed a seasonal sequence. Oxen pulled ploughs through fields before sowing. After harvest, farmers carried stalks to a threshing floor and drove a rough sled, the döven, over them to loosen grain from straw. They then tossed the mixture into the air: wind carried off the lighter chaff, while grain fell for collection and storage. Stored grain supplied households between harvests and kept seed for the next planting. In a 1277 account, warehouses in Kayseri held grain; village property deeds also list underground stores.

Water systems extended cultivation into dry regions. A qanat is a gently sloping underground tunnel that brings groundwater to the surface; gravity carries it from the outlet through channels to fields and gardens. Dams and canals diverted river water, while in Anatolia wooden wheels with attached buckets lifted flowing river water into garden channels. These structures required clearing and repair. In the early twelfth century, Chavli Saqao, governor of Fars in southern Iran, repaired dams there; Seljuk rulers also enlarged the dams and canals of the Murghab River, which watered the Merv oasis in present-day Turkmenistan. Maintaining an upstream channel mattered to cultivators downstream.

Fields and herds supplied one another. Livestock provided draft power and manure, as well as meat, milk, wool and skins for town markets. Pastoral groups moved animals to follow grass and water, while farmers relied on settled fields and irrigation. In 1034–35, a group of 700 or 900 Oghuz Turkic pastoralists crossed the Oxus River from Central Asia into Khorasan, northeastern Iran, after the Ghaznavid ruler Masud refused their request to settle under his protection. In western Azerbaijan and the Jazira, Upper Mesopotamia, earlier Oghuz bands encountered Kurdish herders already using the pasture. These clashes arose from competing demands for grazing land that sustained both mobile and settled households. Cultivators, herders and water users worked within these connected seasonal systems.

Town production and exchange

Rural markets linked villages with larger towns. Farmers brought crops and livestock products to nearby markets, while urban workshops turned raw materials into goods for local use and distant sale. In textile workshops, weavers stretched lengthwise yarns on a loom and passed crosswise threads between them to make cloth; changes in the way threads crossed produced different patterns and textures. The Seljuks inherited established commercial networks. Ninth- and tenth-century geographers described Ahvaz, in Khuzestan in southwestern Iran, as a warehouse centre: goods from inland towns were stored there before transfer to Basra in Iraq for sale and export. They described Nishapur in northeastern Iran as a major trade centre linking merchants with routes toward Khwarazm in the lower Oxus region, Ray near modern Tehran, and Gurgan near the Caspian Sea. Nishapur remained one of the empire’s great cities under Sultan Sanjar, while a twelfth-century account reports textiles and luxury goods carried from Isfahan in central Iran to distant markets. These dated descriptions show the older network that Seljuk rulers governed and the continued role of its major cities.

Anatolia’s inland routes connected with ports on two seas. The Sultanate of Rum took Antalya on the Mediterranean in 1207, recovered it in 1215–16 after a revolt, and captured Sinop on the Black Sea in 1214. Around 1221, Sultan Kayqubad I added Alanya, developing its fortified harbour and shipyard. Caravanserais, roadside inns with space for travellers and their animals, supported movement across the plateau between inland markets and ports. The 1220 treaty with Venice made customs and merchant protection more predictable: Venetian traders paid a two-percent duty on the value of most goods, while grain, pearls, precious stones, and worked or unworked gold and silver were exempt. The agreement also set out protection and procedures for shipwrecks and disputes. Trade and port routes in Rum connected Anatolian roads with Black Sea and Mediterranean shipping.

Coinage and payment

Coins provided one way to settle taxes, wages and purchases. The gold dinar could refer to a physical coin or to an accounting amount. In Seljuk Iran, gold dinars were prominent as minting of silver dirham coins declined in the early eleventh century. Gold dinars from the eleventh and twelfth centuries could vary in weight, even when issued at the same mint in the same year. For a large payment recorded in dinars, people could weigh a group of coins against standard weights rather than assume every piece was identical. An account’s amount and the count of coins therefore did not always match one for one.

The Sultanate of Rum followed a different sequence. Early Seljuk rulers in Anatolia issued copper coins, while silver dirham coins appeared under Sultan Qilij Arslan II in the second half of the twelfth century. Inscriptions on these hand-struck coins named rulers and sometimes overlords, making a small payment object also a public statement of authority. By about 1238, Mongol authorities introduced silver dirhams in Persia using a weight standard comparable to contemporary Rum issues. Seljuk coinage thus reflects distinct regional practices rather than one currency covering all Seljuk lands.

Revenue, service and patronage

Rulers collected taxes and other dues from productive districts, but revenue did not always travel directly to a central treasury. An iqta was an assignment of income, or in some cases administrative authority, linked to service. Under the Great Seljuks, military recipients could be granted the revenue of a district to support their obligations. This did not automatically make them owners of every field there: private estates and endowed lands remained distinct, and the scope of an assignment varied. The arrangement connected local harvests to officials and troops, while also placing pressure on cultivators to meet dues.

The vizier, or chief minister, Nizam al-Mulk advised that iqta holders collect only what had been assigned and that officials be changed periodically, limiting the chance that a collector would turn temporary authority into entrenched local power. Rulers also supported roads, bridges, canals and caravanserais, infrastructure useful to both government and commerce. Religious and charitable foundations received income through waqf, an endowment that set property or its proceeds aside for named purposes. Shops and farms could fund a school, mosque or hospital, linking rents and harvests to ongoing institutional work.

Disruption and regional change

Political conflict could damage the systems that supported production. The Great Seljuk victory at Dandanqan, near Merv, in 1040 secured Khorasan. Later contests among rulers and commanders affected routes and local authority. Seljuk sultan Tughril captured Isfahan in 1051; the following year, the city was described as commercially active, and the new ruler granted three years of tax relief. Residents who had fled returned, and Tughril funded public works. The episode shows how a specific fiscal concession and rebuilding could help restore a major urban centre.

In Anatolia, the Mongol victory at Köse Dağ in 1243 made the Sultanate of Rum tributary, though its institutions continued. Grain shortages prompted imports from the Empire of Nicaea, a Greek-ruled Byzantine successor state in western Anatolia. In 1268, during famine in Venice, the chronicler Martin da Canal listed Turks among its grain suppliers. The contrast between these dated movements shows that political subordination and commerce could coexist: obligations changed, while regional markets continued to move essential goods.
