Central Lithuania
After the occupation of the Vilnius Region by Lucjan Żeligowski (the so-called Bunt Żeligowski), he issued on October 2, 1920, a decree under which a state formally separate from Poland was created in the occupied territories - the so-called Central Lithuania. This state was formally attached to Poland only in April 1922, and then its citizens became Polish citizens (with retroactive effect from March 24, 1922).
