Hachiun

Brother of Genghis Khan

Hachiun, was a full-brother of Genghis Khan and the third child of Yesugei and Hoelun. The Secret History of the Mongols specifies that "when Temujin was 9 years old, Hachiun was five years old." As a child he received a prefix "Alchi" to his name and therefore was referred to as Hachiun-alchi, or Alchidai. He probably had a son whose name was Ilchidey (Iljigdei).
