After Genghis Khan’s death (1227), a kurultai elected Ögedei as Great Khan, creating the political mandate for empire-wide administrative consolidation, including standardizing tribute and taxation practices across newly conquered regions.
Ögedei elevated the Khitan statesman Yelü Chucai to oversee taxation reforms in Mongol-controlled North China, helping build a more regularized fiscal administration that favored revenue extraction through bureaucracy rather than indiscriminate plunder.
Ögedei formalized the yam relay-post system across the empire, staffing stations and supplying remounts and rations for envoys. The system had fiscal implications because designated households were tasked with provisioning obligations (treated as a specific tax duty rather than ordinary levies).
Shigi Qutuqu, a senior imperial official, was appointed to top administrative responsibility in North China, positioning him to implement registration and fiscal changes tied to state revenue collection.
A general census in North China (centered on the former Jin territories) was carried out in 1235–1236, updating household registers as a basis for more systematic taxation and administration under Ögedei’s government.
Ögedei issued measures aimed at restraining elite abuses—such as limits on unauthorized use of paiza authority and other demands on civilians—reflecting a broader effort to channel extraction through regulated institutions rather than ad hoc requisition.
Yelü Chucai’s death removed a key advocate of bureaucratic, predictable taxation in North China, contributing to shifts in fiscal practice and influence at court during the later Ögedei period and subsequent regencies.
Möngke’s accession brought a renewed drive to discipline fiscal extraction: central authorities emphasized controlling abuses by nobles and officials and making revenues more legible through registers and standardized assessments.
Möngke initiated an empire-wide census beginning in 1252, designed to register households and productive resources and to underpin more predictable taxation and obligations across diverse regions of the empire.
In 1253, Möngke established a Department of Monetary Affairs to tighten control over currency issuance (especially paper money in Mongol-ruled China), linking monetary governance to fiscal stability and state revenue collection.
Following Möngke-era restructuring in the west, a census was undertaken in Khorasan and parts of Iran in the early 1250s, associated with introducing/expanding the qopčūr (qubchur) from a pasture-related levy toward broader, more systematized taxation (including poll-tax-like assessments on sedentary populations).
A further census in Persia is commonly dated to 1254 under Arghun Aqa, aligning western fiscal administration with Möngke’s broader census-and-taxation program and helping regularize obligations amid earlier financial disorder.
News of Mongol census-taking and the taxes it enabled triggered resistance in Novgorod in 1257. The episode illustrates how Möngke’s fiscal-registration policies could provoke unrest when extended to semi-autonomous or distant regions.
In 1258, Alexander Nevsky helped force Novgorod to submit to Mongol enumeration and taxation, reinforcing the linkage between the census and a more routinized tributary/tax apparatus in the northwest.
The empire-wide census program initiated under Möngke took years to complete; Novgorod was counted in winter 1258–1259, marking a key endpoint of the registration effort used to standardize fiscal obligations.
Möngke died in 1259, ending the 1250s reform drive from Karakorum. His death helped shift the empire toward intensified succession conflict and increasing fiscal-administrative divergence across emerging regional khanates.
