Central Lithuania
Central Lithuania was a pseudo independent state, created in 1920 by allegedly rebelious soldiers of Lithuanian-Belorussian division of Polish army.
Following the start of Polish-Soviet war, in 1919 was occupied by Red Army that were pushed back by Polish Army. In 1920 was again occupied by Red Army, that officially recognized sovereignity of Lithuanian Soviet Republic over the city. Probably Lenin was waiting for capture of Warsaw, to occupy the rest of Lithuania. However, when Red Army was defeated in the Warsaw battle, Soviets made decision to hand over the city to Lithuania. The Polish commander Pilsudski was emotionally connected to the city, so he ordered his subordinate to rebel his and capture the city, without declaring the war on Lithuania.
Officially the new country, called Central Lithuania, that inlcuded also some neighbouring Belorusian territories. After 1922 election, Polish majority of 65% voted for annexation of the country to Poland, that was never officially recognised by Lithuania After Soviet-Nazi pact 1939 Lithuania was given the Vilnius County.History
