Establishment of Mongol Rule in Persia

Timeline

1. 1221–1227Persia · PersiaAfter the Mongol conquests destroyed the Khwarazmian Empire, cities across the Iranian Plateau fell one after another and the old sultanate regimes collapsed. Over the following years Mongol forces remained stationed or repeatedly swept through, while local strongmen and remnant forces carved out their own domains; imperial control of Persia gradually transitioned from military occupation toward administrative integration.
2. 1229Persia · PersiaAfter acceding to the throne, Ögedei appointed Mongol darughachis (garrison governors) at strategic points across Persia to supervise local civil and military affairs. At the same time he used submitting local warlords (such as Mongol generals and local nobles in Khurasan) to maintain order, bringing Persia into the empire's postal relay (yam) and conscription systems to keep the western expedition's logistics corridor open.
3. 1229–1230Persia · PersiaBy 1229–1230, tax collection, population registers, and military conscription in Persian cities all had to be reported to the great khagan's court. The Mongols restored some agriculture and commerce in Khurasan and elsewhere while continuing to conscript Persian manpower for subsequent western campaigns. Persia thereby became the core ruling zone of the Mongol Empire's West Asian sector, pre-setting the territorial and administrative framework for Hulegu's establishment of the Ilkhanate in the 1250s.
