Lithuanian–Byelorussian Soviet Socialist Republic

The Lithuanian Soviet Socialist Republic (LSSR) was a short-lived Soviet puppet state during the early Interwar period. It was declared on 16 December 1918 by a provisional revolutionary government led by Vincas Mickevičius-Kapsukas. It ceased to exist on 27 February 1919, when it was merged with the Socialist Soviet Republic of Byelorussia to form the Lithuanian–Byelorussian Soviet Socialist Republic (Litbel).
