Chagatai language
The name "Mughal" is derived from the original homelands of the Timurids, the Central Asian (Turkestan) steppes once conquered by Genghis Khan and hence known as "Moghulistan", "Land of Mongols". Although early Mughals spoke the Chagatai language and maintained some Turko-Mongol practices, they became essentially Persianized and transferred the Persian literary and high culture to South Asia, thus forming the base for the Indo-Persian culture and the Spread of Islam in South Asia.
