Changshi was one of the last effective khans (r. 1335-1338) of the Chagatai Khanate. His father was prince Ebugen who was the son of Duwa, the Chagatai Khan.
Western sources claimed that he was anti-Muslim and quite tolerant toward Christians. Before his succession, Changshi sent the YuanGreat KhanTugh Temur 170 Russian prisoners. However, he was probably Nestorian. He was given a pecuniary reward from the court of Yuan Dynasty. He overthrew Muslim princes from the power of the ulus in 1334–1335. But he was murdered by his family in 1338 after a short period of his reign. He was succeeded by his younger brother, Yesun Temur.
