In the area, which was mainly inhabited by Buryats until the 20th century, one of two “foreign tribal offices” (inorodcheskaja uprawa) of the then okrug Verkholensk of the Irkutsk governorate was set up in the Jelanzy settlement . On January 9, 1922, the village came to Echirit-Bulagatski aimak ( Buryat name for Rajon; today the Rajon of the same name, based in Ust-Ordynski, a good 100 km to the west ) of the newly formed Mongolian-Buryat Autonomous Oblast, from which the Buryat-Mongolian in 1923 ASSR emerged . On February 11, 1935, Jelanzy became the administrative seat of the outsourced Olchonski aimak. From September 26, 1937, most of the associated areas northwest of Lake Baikal formed the Ust-Ordynsk Buryat Autonomous Okrug, but the Olkhonsky aimak came to Irkutsk Oblast and was referred to as Rajon from 1939.
