Northern Yuan
In 1434, Eastern Mongol Taisun Khan's (1433–1452) Oirat prime minister Togoon Taish reunited the Mongols after killing Adai Khan in Ejin. Togoon died in 1439 and his son Esen Taish became ruler of Northern Yuan dynasty. Esen later unified the Mongol tribes. The Ming dynasty attempted to invade the Northern Yuan in the 14th to 16th centuries. However, the Ming dynasty was defeated by the Oirat, Southern Mongol, Eastern Mongol, and united Mongol armies. Esen's 30,000 cavalries defeated 500,000 Chinese soldiers in the 1449 Tumu Crisis. Within eighteen months of his defeat of the titular Khan Taisun, in 1453, Esen himself took the title of Great Khan (1454–1455) of the Great Yuan.
