The Mongol tribe had lived around Mount Burkhan Khaldun since at least the time of Borte Chino, 12 generations before Bodonchar Munkhag or around 600CE. They shared the area with the ancient Uriankhai tribe, a prominent Shiwei tribe named Wuluohu (烏羅護) in the Chinese histories. There they lived a pastoral life supplemented by hunting the abundant game of the surrounding forested mountains. To the north was located the Bargut tribe (around Lake Baikal) and the Khori Tumed tribe (also around Lake Baikal). To the east was located the Tatar tribes (Airigud Tatar, Buirigud Tatar etc.) who also belonged to the Shiwei group. Slightly to the west of the Mongols were the ancient Bayid tribe. These are the pre-Butunchar early tribes mentioned in the Secret History that had marriage relations with the early Mongols.
