The Hamnigan Buryats or Khamnigan are Mongolized Evenks of Tungusic origin. Khamnigan is the Buriat-Mongolian term for all Ewenkis. In the early 16th century, the Evenks of Transbaikalia or Khamnigans were tributary to the Khalkha. The Khamnigan are only ethnic group of Tungus origin in Mongolia. They who lived around Nerchinsk and the Aga steppe faced both Cossack demands for tribute and Khori-Buriats trying to occupy their pastures. Most of them came under the Cossack rule and enrolled the Cossack regiments in the Selenge valley. The Khori Buriats occupied most of the Aga steppe and forced the Ewenkis to flee to the Qing Dynasty.
After 1880 Russia's Khamnigan Evenks moved to semi nomadic herding of cattle, sheep, camels and horses. Some time after 1918 the Evenks, along with their Buriat neighbors, fled over the border into Mongolia and Hulun Buir, establishing the current Khamnigan communities there. The Khamnigan of Mongolia, numbering 300 households, are scattered among the Buriats and speak only the Khamnigan dialect of Buriat language. They live around the Yeruu Lake, Dornod and Khentii provinces as well as Möngönmorit of Töv Province.
