モンゴル高原
Dayan Khan and his queen, Mandukhai, eliminated Oirat power and abolished the taishi system used by both local and foreign warlords. Dayan Khan's victory at Dalan Tergin reunified the Mongols and solidified their identity as Chinggisid people. His decision to divide the Six tumens of Eastern Mongolia as fiefs for his sons created decentralized but stable Borjigin rule over the Mongolian Plateau for a century.
