Bayan (or Buyan; Naiyan; r. 1302–1309) was one of the most famous khans of White Horde.
Bayan fought his rebel cousin, Koblek, and Kaidu's forces several times.
[citation needed] Buyan also tried to ally with Temür Khan of the Yuan dynasty, the suzerain of Mongol Empire, against the Chagatai Khanate and Khaidu.
[2] Howorth, writing in 1880[3] thinks that Kobluk was based in Gazni and Bamiyan.
He says that Berke loaned Hulagu some troops and that when these two broke some of them went east and founded a new principality in what is now Afghanistan and claimed to be subjects of the distant Golden Horde.
