Ilkhanid Government, Revenue, and Regional Administration

Founded through Hulegu’s conquests from 1256, the Ilkhanate governed territories centred on Iran and Iraq, with authority extending at different times across Azerbaijan, the Caucasus, Anatolia, and neighbouring regions. It became politically independent after the wider Mongol succession crisis of 1259, though its rulers maintained ties to the Great Khan. The state endured until the death of Abu Sa’id in 1335. Its administration joined Mongol rulers and military commanders with Persian-speaking officials and older regional practices. Ghazan’s reign, from 1295 to 1304, brought a concentrated effort to make revenue and government more predictable, but reforms did not erase local differences or the demands placed on rural communities.

Ruling through the court and the divan

The Ilkhan stood at the head of a court where authority depended on both descent from Genghis Khan and the support of powerful Mongol emirs, or military commanders. The ruler’s court and army moved within a political world that retained Mongol customs, even as the state relied increasingly on settled administrative centres. Maragheh, Tabriz, and later Soltaniyeh served as important centres of rule. After a general peace among the Mongol khanates in 1304, the Ilkhans acknowledged the Yuan emperor’s nominal supremacy while governing their own realm with substantial political autonomy.

The central divan, the state’s principal administrative bureau, brought together senior officials responsible for government business. Viziers supervised civil administration and finances, while military emirs held influence at court and in the provinces. Mongolian remained important at the upper levels of government, while Persian was widely used in administration and official documents. Mongolian, Turkic, Persian, and Arabic could all appear in documentary practice. This was not a simple replacement of one system by another: Mongol political authority operated through a civil administration shaped by established Iranian practices.

Officials did not all come from the same religious or family background. Sa’ad al-Dawla, a Jewish official, served as vizier under Arghun, and Rashid al-Din, who had converted to Islam, became one of the leading viziers of Ghazan and Öljaitü. Their careers show that high office could be open to people outside long-established Muslim administrative families, although advancement remained dependent on a ruler’s trust and the shifting balance of court politics.

Provincial rule and regional differences

Ilkhanid control varied across the realm. Some areas were administered directly through governors and officials appointed by the court; elsewhere, local dynasties or Mongol commanders retained considerable room to govern. The Kartid rulers of Herat, for example, maintained an autonomous position. Qara’unas Mongols exercised authority in Khorasan as a largely autonomous regional power. Anatolia’s Seljuk sultanate also existed within the Ilkhanid political order as a vassal, but provincial revolts demonstrated that formal subordination did not guarantee obedience.

Governorships were important sources of authority and income, and appointments could strengthen networks around the court. Under Ghazan and Öljaitü, members of vizier Rashid al-Din’s family held provincial offices. Such appointments could extend the reach of central government, but they also concentrated influence in trusted households. Court alliances and rivalries therefore shaped administration alongside formal offices.

Provincial resources reached the court through different arrangements. A tax-farmer might advance money or provide a guarantor, then collect the agreed revenue locally. Clearing accounts could trigger disputes over what had been collected or owed. Revenue administration therefore depended on contracts, coercion and the position of officials as well as on nominal provincial boundaries.

Taxation and Ghazan’s fiscal reforms

Revenue came from land, herds, people and trade. The kharaj was a land tax; qupchur developed from a levy on livestock and could take other assessed forms. Rates and collection differed across populations and regions. Registers and surveys offered a way to identify obligations, but officials also faced demands for advances and extraordinary payments.

Assignments called barats were drafts on provincial revenues: an official or beneficiary could present one to obtain an assigned payment. They multiplied demands on local collectors and taxpayers. Ghazan’s programme sought to control such claims and publish assessments in money or produce. Sealed schedules at the centre and public copies locally were intended to make unauthorised additional demands easier to identify.

Ghazan also sought to standardize coinage, weights, and measures, making transactions between regions easier to administer. An earlier attempt to introduce paper money on a Yuan model under Gaykhatu had not gained lasting acceptance. Ghazan declined to impose it in Khorasan, citing local conditions. The contrast shows that Ilkhanid rulers could draw on practices from elsewhere in the Mongol Empire without applying them uniformly.

Other reforms targeted costs charged to the state and its subjects. Ghazan restricted the use of official messengers for the private errands of royal women, princes, and other individuals. Staffed postal relays, part of the Mongol yām network, were reserved for urgent military intelligence. Court envoys received a daily allowance, while noble envoys were expected to travel at their own expense. Ghazan also abolished the lodging obligation known as nuzul, which required communities to provide accommodation and supplies, and reduced spending on royal hunts. These measures aimed to prevent public resources from being diverted to private use and to limit some demands on local populations.

Land grants, cultivation, and labour

Restoring cultivation formed part of Ghazan’s programme. Repairing irrigation, bringing abandoned land into use and giving cultivators more predictable obligations could increase both production and revenue. Rural recovery depended on maintaining water supplies and allowing households to remain on the land without repeated disruptive exactions.

An edict of 1303–1304 proposed revenue assignments called iqtas for the army. Commanders would distribute shares to subordinate ranks, supporting military personnel from designated districts. Cultivation remained the work of peasants and enslaved labourers rather than turning the soldiers themselves into farmers. Issued near Ghazan’s death, the programme’s full implementation is uncertain.

Fiscal regulation did not mean that rural people gained freedom from state demands. Rules allowed fugitive peasants to be sought and returned for a period of thirty years, reinforcing their attachment to the land. Agricultural slavery continued. In state workshops, enslaved artisans were shifted from receiving rations to paying a form of rent or tribute after managers were reported to have diverted their supplies. These arrangements reveal the limits of reform: the court sought a more efficient revenue system while continuing to rely on constrained labour.

Royal edicts, seals, and judicial proceedings

Ghazan sought to control royal edicts, called jarliqs, through prescribed forms, graded seals and central records. A paiza was a credential carried by an authorised person, identifying access to official support. Recording holders and recovering credentials when an appointment ended could restrict unauthorised use. Seals authenticated documents; credentials identified their bearers.

These measures did not amount to a single, comprehensive legal code. The Mongol Yasa, a body of Mongol customary rules and commands, remained in use during Ghazan’s reign and that of his successor Öljaitü. After Ghazan converted to Islam in 1295, Islam became the state religion, but the religious change did not simply replace Mongol political traditions. Ilkhanid government continued to combine Mongol authority, the ruler’s edicts, and the work of regional officials.

A yargu, or judicial inquiry, could also become entangled in struggles among senior officials. Under Öljaitü, vizier Sa’ad al-Din Savaji faced an embezzlement charge and was heard in a yargu in 1312. He initially defended himself, but was later executed with several supporters. The episode illustrates both the use of formal proceedings and the risks faced by officials whose fortunes depended on political favour.

Vizierial patronage and the Rab’-e Rashidi

Rashid al-Din’s career shows how a senior administrator could combine state service with substantial patronage. A vizier under Ghazan and Öljaitü, he helped direct government while supporting institutions in Tabriz. His Rab’-e Rashidi was a privately financed foundation and urban quarter that included educational and medical facilities, craft workshops, and a library. These provisions were an elite project rather than a general system of public services, but they show how a powerful official could organize people, resources, and skilled work beyond the central offices of government.

Rashid al-Din’s foundation supported the copying of manuscripts. Regulations specified paper, script, comparison with an authoritative original, binding and registration before distribution to schools. These operations required scribes and supervisors as well as funds. Finished volumes went to schools for consultation and further copying, extending the project beyond Tabriz.

Rashid al-Din’s fall from power also exposed the fragility of such patronage. He was executed in 1318 after a charge of poisoning Öljaitü, and his property was confiscated. The Rab’-e Rashidi and its collections were taken over by Mongol soldiers. After Abu Sa’id’s death in 1335, the Ilkhanate fragmented as regional leaders and competing claimants asserted power. The central government’s reach had always depended on maintaining cooperation among rulers, military commanders, officials, and provincial authorities; once that balance weakened, its fiscal and administrative arrangements could not preserve political unity.
