Ambaghai

He was the Leader of the Taichud clan, one of the sub-branches of the Borjigid, and also grandson and successor of Charaqai Lingqum.

A member of the cadet branch of Borjigin clan, he was ruler of the Taichuud tribe and later khan of Khamag Mongol.

According to Chih-Shu Eva Cheng's calculation, he died c. 1156 at the same time as Marcus, khan of the Naimans and father of Cyriacus.

His son Qadaan Taishi followed him as de facto chief of Taichuud and joined Hotula Khan on his campaigns against Tatars.

In 1211 Genghis Khan instigated the Mongol–Jin War, ending in the fall of the Jin dynasty, in sworn revenge for Ambaghai's kidnapping and execution.
