Taxation, Land Revenue and Public Resources

The Umayyad caliphate, a state ruled by a Muslim caliph, governed from Damascus in Syria from 661 to 750. In Iberia, the peninsula now occupied chiefly by Spain and Portugal, a separate Umayyad emirate began in Córdoba under emir ʿAbd al-Raḥmān I in 756; an emir was the state’s ruler. In 929, ʿAbd al-Raḥmān III proclaimed a caliphate there, which lasted until 1031. Both governments relied on local collectors and records to turn claims on land, produce and people into resources for officials, soldiers and courts. Agricultural land and the people cultivating it supplied an important part of that revenue, but the route from field to treasury differed by province and political settlement.

Registers and official duties

A dīwān was both a register and the government office responsible for its records. Early registers listed tax payments alongside Arab warriors entitled to stipends, regular state salary payments, and the rates they should receive. By the start of Umayyad rule, Damascus had a central dīwān al-kharāj, a fiscal bureau handling assessments, receipts and taxation in conquered territories. Separate offices managed official correspondence, seals that authenticated documents and checked for forgery, and the army payroll.

This organization connected provincial receipts to state spending. The army office kept salary lists for Arab warriors; fiscal offices recorded what came in. Historian Marie Legendre describes Umayyad revenues as mainly spent within the provinces, matching a government whose governors and local officials handled much of its administration. Damascus in Syria, the former Byzantine provinces of the Eastern Roman Empire, and the lands of the Sasanian Persian Empire in Iraq and Iran thus fed a connected bureaucracy while retaining different inherited procedures.

In Iraq, the Umayyads initially continued to use Persian for official fiscal business. The governor Ziyād ibn Abīhi employed the Persian secretary Zādān-Farrōḵ in the land-revenue bureau. Under the governor al-Ḥajjāj, the change to Arabic registers in Iraq was initiated in 697, with technical help from another Persian official, Ṣāliḥ ibn ʿAbd al-Raḥmān. Farther east in Khorasan, Persian remained in administrative use until 739, near the end of Umayyad rule.

Land, persons and tribute

Jizya came to mean a personal poll tax, a levy assessed on an eligible person rather than directly on acreage; legal treatments generally assigned it to adult, free and capable non-Muslim men. Kharāj came to refer to a tax on land, including land held by Muslims and non-Muslims. Iranian-history scholar Vera Basch Moreen explains that the clearer distinction developed over time: early records could use the words interchangeably or for tribute, and a cultivator’s conversion could end the personal levy without ending a tax attached to the land.

In the Persian provinces, many towns surrendered under agreements that required an annual fixed sum along with goods or services. Local landholding gentry collected the tribute and remained responsible for delivering the assessed total to Arab governors. In Khorasan, some earlier arrangements shifted from a lump-sum tribute toward a tax related to land. The local collector’s task joined village resources to a province-wide obligation.

Khorasan: conversion and military pay

Khorasan was the eastern frontier region of the caliphate, including northeastern Iran, parts of present-day Afghanistan and lands beyond the Oxus River in Central Asia. At first, Arab forces did not settle in large numbers there. Treaties left many local rulers in place to collect payments, sometimes in cash and sometimes in kind, while existing social hierarchies remained intact. As garrison settlements grew, the government’s relationship with the region changed from distant extraction toward a resident military and administrative presence.

During caliph ʿUmar II’s reign (717–720), a delegation from Khorasan reported that non-Arab Muslim clients, called mawālī, served in campaigns without the salary and maintenance payments given to other soldiers, while converts to Islam still paid jizya. ʿUmar II abolished that tax for new converts, after which many people converted. A governor then required circumcision as proof of conversion; ʿUmar stopped that test. Administrators later reinstated jizya for some converts, and some renounced Islam in response. The dispute joined religious status to which residents owed a personal tax and which soldiers received public pay.

Governor Ashras ibn ʿAbd Allāh al-Sulamī renewed the conversion campaign in 727–730 by promising that new Muslims would pay no jizya, only kharāj. When revenue fell, officials again required circumcision and a Qur’an recitation to test conversion claims. In 734, al-Ḥārith ibn Surayj led a revolt whose demands included ending unlawful taxes on Muslims and providing proper pensions.

North African towns, frontiers and the army

Umayyad North Africa joined older coastal cities to a frontier stretching across the Maghrib. In the former Byzantine provinces, Latin-speaking urban communities lived among productive plains and an export economy based on goods such as grain and olive oil; they also had inherited tax administration. Farther south and west, Berber communities lived in more lightly settled regions where pastoralism and subsistence farming were important. These different landscapes gave governors distinct ways to raise and organize resources.

In Ifriqiya, the eastern Maghrib centered on modern Tunisia, the new garrison city of Kairouan was founded in 670 to house soldiers and their families, where the state could control and pay them. Berber converts served as guards and soldiers in Umayyad armies. As in Khorasan, ʿUmar II’s policy treated non-Arab Muslims as eligible for stipends and removed jizya from them. This connected provincial revenue directly to the organization of a frontier army.

Under the governor ʿUbayd Allāh in 734, Berber Muslims again faced jizya, kharāj and demands for enslaved people as tribute. Historian Corisande Fenwick relates these collections to the revolt that began in Morocco in 739–740 and spread across North Africa and al-Andalus. Berber soldiers protested unequal treatment and the handling of booty, while rural and urban residents also opposed renewed taxes. Revenue collection shaped both the provincial budget and who was willing to serve the state.

A governor’s tax order from Egypt

A Greek papyrus letter dated 18 September 710 shows the collection chain at work in Egypt. Qurra ibn Sharīk, the governor, wrote to Basileios, the local administrator of Aphrodito, ordering him to collect public gold taxes promptly and send them to the governor with no balance left in arrears. The papyrus makes a provincial governor’s demand concrete: a local administrator gathered the due payment, then had to account for the remainder when reporting in person.

Al-Andalus: registers, remittances and a Córdoba court

After the conquest of Iberia, the governors of al-Andalus used courts and records to administer the new province. The Chronicle of 754, a contemporary Latin Christian account, says that al-Ḥurr sent judges through Spain to assess taxes and restored property to Christians so its revenue could enter the public treasury. Its account also associates al-Samḥ with further fiscal measures and the distribution of booty. Separately, the Arabic chronicle Akhbār majmūʿa credits al-Samḥ with systematically asking whether each territorial acquisition had surrendered peacefully or been taken by force, a distinction used to set terms for its inhabitants.

Military arrivals could create sudden demands. In 743–745, governor Abū l-Khaṭṭār required additional taxes from Athanagild, the son of the local ruler Tudmīr, after Syrian troops arrived. The Chronicle of 754 reports that 27,000 solidi, late Roman gold accounting units, were raised in three days. A later governor, Yūsuf al-Fihrī, ordered a new census and removed deceased Christian taxpayers from the public registers, changing the names on which future demands rested.

The Cordoban Umayyad emirate, and then the caliphate proclaimed in 929, developed its own fiscal centre. For the reign of al-Ḥakam II (961–976), historian Eduardo Manzano Moreno estimates annual tax revenues of about ten million dinars, the gold currency unit used in these accounts. His study links the surplus to a centralized court demand for luxury goods and services that supported urban manufacture and long-distance trade, while fiscal coercion created tension with the caliph’s claim to rule according to Islamic principles.
