Mongol conquest of Persia and Mesopotamia

The Mongol conquest of Persia and Mesopotamia comprised several Mongol campaigns against Muslim states in the Middle East and Central Asia between 1219 and 1258. These campaigns led to the termination of the Khwarazmian Empire, the Nizari Ismaili state, and the Abbasid Caliphate of Baghdad, and the establishment of the Mongol Ilkhanate in Persia.
