Bayan-Ölgii Province
Historically, Ulaankhus was settled by Kazakhs who moved to the northern side of the Altai Mountains. In 1922, Sherushy khoshuun with the canter in Akbalshyk, currently Bilüü, was established. In 1922, it was split into Sherushy and Shebaraigyr, and in 1925 into Sherushy, Shebaraigyr, Botakara, and Zhantekey. These khoshuuns belonged to Khovd Province. In 1938, Sherushy khoshuun was renamed Ulaankhus sum. In 1940, Bayan-Ölgii Province was established, and the sum was subordinated to this province.
