# Lithuanian Separate Corps

The Lithuanian Separate Corps (Russian: Литовский отдельный корпус, romanized: Litovskiy otdel'nyy korpus, lit. 'Lithuanian Separate Corps', Lithuanian: Lietuviškasis atskirasis korpusas, Polish: Korpus Litewski) was a corps of the Imperial Russian Army, created in 1817. After the Russo-Turkish War (1828–1829), the Lithuanian Corps was renamed as the VI Corps. The Lithuanian Corps was disbanded in 1831 after the Polish–Lithuanian Uprising of 1831.
The corps, except for the guard units, was recruited from Lithuanians and Poles, which set it apart from the rest of the Imperial Russian Army. The guard units were recruited mostly from Russians.

## Formation

The Lithuanian Corps was formed on 1 July 1817 by Tsar Alexander I of Russia who made Grand Duke Konstantin Pavlovich of Russia its commander as the latter was already the commander of the Army of Congress Poland. The Lithuanian Corps recruited in the five provinces of Vilna, Grodno, Minsk, Volhynia and Podolia and Belostok Oblast, all of which together made up the Russian Empire's so-called Western Krai. The Corps was widely stationed throughout the territory of the governorates of Volhynia, Minsk and Grodno.
The Lithuanian Corps consisted of 2 infantry divisions, each containing 2 brigades, 2 artillery brigades as well as guard and grenadier regiments. Together with the Polish Guard, the Lithuanian Corps' Guards and Grenadiers regiments formed the Guard Reserve Corps, also established in 1817. The Guard Reserve Corps was stationed in Congress Poland and was commanded by General Wincenty Krasiński. The unit was disbanded in 1831.
