Turkmen-origin revolts seen in the Seljuk State of Turkey after Mongolian invasion

The Seljuk State of Turkey defeated the Kharzem shah state in the Battle of Yassı Çimen in 627/1230, leading up to the destruction of this state. After the war, the Seljuk State of Turkey became a neighboring state with the Mongols. Consequently, the Mongols turned to Anatolian lands, which began to weaken, in order to carry out their invasion activities. Turkmen revolts of religious-political or purely religious origin, which were seen in small numbers until the reign of Izzeddin Keykavus II, showed a sudden numerical increase after the reign of Keykavus II. Economic troubles were among the causes of the revolts. The main reason for the increase of Turkmen rebellions and the change of purpose can be attributed to the heavy taxes given to the Mongols after the state entering a period of regression and collapse with 634/1243 Kösedag War. Mongol invasions while tried to tear apart the Seljuk State of Turkey from the outside; Turkmen revolts, incompetent statesmen, sultans who were unaware of the state's rule also led to the internal collapsing of the state. In our study, Turkmen origin revolts and the factors that led to the destruction of the Seljuk State of Turkey after the Mongols invaded Anatolian lands were discussed together.
