Ulaghchi Khan

Ulaghchi Khan (died 1257) was the third ruler of the Golden Horde, succeeding Sartaq Khan for less than a year in 1257. A direct descendant of Batu, he was either Sartaq's son or younger brother. The great khan Möngke nominated him while he was still a child, and Batu's senior widow Boraqchin governed as regent.

Ulaghchi died before he could rule in person, and the throne passed to Batu's brother Berke. Berke later had Boraqchin executed for treason after she sought Hulagu's protection.
