Boroldai

Boroldai (or Burulday, Borolday), also known as Burundai, (Cyrillic: Боролдай) (died 1262) was a notable Mongol general of the mid 13th century. He participated in the Mongol invasion of Russia and Europe in 1236-1242^[1] and other Mongol raids to Europe until 1263.

The clan of Borolday is not clear. He was probably from one of four tribes that Chinggis Khaan (1162–1227) assigned to his eldest son, Jochi: the Sanchi'ud (or Salji'ud), Keniges, Uushin, and Je'ured clans.
