Yesun Temur (Chagatai Khanate)

Yesun Temur (Есөнтөмөр; ) was a Tengric khan (r. 1337–1339) of Chagatai Khanate. He was the younger brother of Changshi Khan. His name literally means "Nine Iron" in the Mongolian language.

In order to take power, Yesun Temur is said to have poisoned (murdered) his brother. He regretted his action and blamed his mother for Changshi's death. His guilt caused him to become very stressed, which led to excessive drinking. He was overthrown by 'Ali-Sultan of the House of Ogedei in 1339.
