Chagatai is an extinct Turkic language which was once widely spoken in Central Asia, and remained the shared literary language there until the early 20th century. As part of the preparation for the 1924 establishment of the Soviet Republic of Uzbekistan, Chagatai was officially renamed "Old Uzbek", which Edward A. Allworth argued "badly distorted the literary history of the region" and was used to give authors such as the 15th-century author Ali-Shir Nava'i an Uzbek identity.
The Chagatai language was completely extinct by the 1700s.
