Tarmashirin

Ala-ad-din Tarmashirin (died 1334), a son of Duwa, ruled the Chagatai Khanate from 1331. Before his enthronement he led a plundering raid into the Delhi Sultanate in 1327 and sacked Lahore in 1329. One of the first Chagatai khans to embrace Islam, his faith and preference for the cities of Transoxiana angered his traditionalist nobles, who charged him with abandoning the Yassa.

He was deposed at a kurultai and overtaken near Samarkand. There, in 1334, the eastern princes under Buzan killed him.
