Moghulistan, also called the Moghul Khanate or the Eastern Chagatai Khanate, was a Muslim, Mongol, and later Turkic breakaway khanate of the Chagatai Khanate and a historical geographic area north of the Tengri Tagh mountain range, on the border of Central Asia and East Asia. That area today includes parts of Kazakhstan, Kyrgyzstan, and northwest Xinjiang, China. The khanate nominally ruled over the area from the mid-14th century until the late 17th century.
Beginning in the mid-14th century a new khanate, in the form of a nomadic tribal confederacy headed by a member of the family of Chagatai, arose in the region of the Ili River. It is therefore considered to be a continuation of the Chagatai Khanate, but it is also referred to as the Moghul Khanate.
