Chagatai Khanate

13th–14th-century Mongol khanate in Central Asia

The Chagatai Khanate, also known as the Chagatai Ulus, was a Mongol khanate that comprised the lands ruled by Chagatai Khan, second son of Genghis Khan, and his descendants and successors. Over time, its Mongol ruling groups underwent a gradual and uneven process of linguistic and cultural Turkification and Islamization, though Mongolian political and administrative traditions remained important. Mongolian language continued to be used for official documents into the 14th century; Tughlugh Timur and Ilyas Khoja, the first Chaghatayid rulers of Moghulistan, still issued royal edicts in Mongolian.
