Büri

Büri (died 1252) was a son of Mutukan and a grandson of Chagatai Khan, who raised him after Mutukan was killed at Bamyan in 1221; his Turkic name means wolf. Brave, hot-tempered and quarrelsome in drink, he joined Batu's western campaign from 1236, but he and Güyük mocked Batu, and Ögedei recalled him in disgrace.

In 1241 he ravaged Wallachia and Transylvania, and later settled German miners on his appanage near Talas. After backing the regent Oghul Qaimish against Möngke, he was handed to Batu and executed in 1252.
