The attempted unification of the Oirats caused dissension among the tribes and their Chief Tayishis who were independent minded but also highly regarded leaders themselves. This dissension reputedly caused Kho Orluk to move the Torghut tribe and elements of the Dörbet tribe westward to the Volga region where his descendants formed the Kalmyk Khanate. In the east, Güshi Khan took part of the Khoshut to the Tsaidam and Qinghai regions in the Tibetan Plateau, where he formed the Khoshut Khanate to protect Tibet and the Gelug from both internal and external enemies. Kharkhul and his descendants, by contrast, formed the Dzungar Khanate to fight the Khalkha.
