Tolbot, Genghis Khan's 16th generation descendent, migrated from the Hangai Mountain to the south of the Gobi Desert. Ongondular, Tolbot's the youngest son, began to call his tribe Ujumchin, which means the people of the Grape Mountain, because that was their ancestral homeland before the migration.
During the Tai Zhu years of Late Jin, Dorji, the head of the Ujumchin tribe, lead his tribe to the Keluren River due to his dispute with Linden Khan, who was the ruler of the Mongol Tribes at the time. In the first year of Cong De (1636), the Ujumchin tribe submitted to the Qing Dynasty. In the third year of Shun Zhi (1646), Ujumchin was divided into two banners, Left and Right Wing Banners. The governor of the Left Wing Banner stayed at Kuisutolohai stand at the bank of Orhu River (Ulagai River). In 1934 Ujumchin joined the Xilingol League.
In 1945, Dorji Khan, the head of Ujumchin Left Wing Banner, led half of the banner's population to the vicinity of the Keluren River in Outer Mongolia after his defeat by the army of Ulanhu, who later became the first governor of Inner Mongolia Autonomous Region. The descendents of Dorji Khan and his followers still lived in the same area in Outer Mongolia today.
In 1946, the Left Wing Banner of Ujumchin was named East Ujumchin Banner. After the liberation, East Ujumchin Banner maintained and developed its traditional animal husbandry. Since 1991 it has been the top county in China in terms of live-stock number.
