Büri
Büri was a son of Mutukan and a grandson of Chagatai Khan. According to Rashid-al-Din Hamadani, Büri's mother was a wife of Chagatai Khan's one official. She was a beauty, and Mutukan was attracted by her while she served in the Khan's ger. Mutukan made her pregnant and instead of marrying her, he took her baby, Büri.
Mutuken was killed during the siege of Bamiyan. Chagatai raised Buri because Mutukan was his favorite son. Both of them were recalled by Great Khan Ogodei, and Buri was sent to his grandfather Chagatai when Batu complained about them to his uncle. After a year in Mongolia, he returned to Batu to participate in the invasion of Europe. When the Mongols advanced into Central Europe, he ravaged Wallachia. He had German miners and Teutonic knights put to work in Zungaria. They were captives of the Battle of Legnica.
After Guyuk's death in 1248, he sided with regent Oghul Qaimish khatun. Batu and Möngke had Buri murdered by a Golden Horde general who disliked him in 1252.
