The Transbaikal Cossack Host was one of those created during the 19th century as the Russian Empire expanded to the Far East and South-East. It remained smaller than the Don Cossacks and other longer-established Hosts. The Transbaikal Cossack Host partially consisted of
Siberian Cossacks,
Buryats,
Evenk (Tungus) military units, and included the
peasant population of some of the regions. The military component included three
cavalry regiments and three unmounted
brigades. Its main purpose was to patrol the
Sino-Russian border and perform everyday military duties in the region. The official leader of the Transbaikal Cossack Host had the title of
Nakazny ataman ("the one who was appointed"). From 1872 he also served as military governor of the Transbaikal
oblast, which had with its
headquarters in
Chita. In the early 20th century, the Transbaikal Cossack Host normally supplied one
polusotnya (fifty men) of guards for rural policing work, four cavalry regiments, and two
batteries in time of peace. During
World War I, the Host expanded to one polusotnya, nine cavalry regiments, four batteries, and three reserve
sotnyas (each of one hundred men). In 1916, the Cossack population of the Transbaikal Cossack Host numbered 265,000 people, out of which 14,500 men served in the military. ==History==
