following the Polish–Lithuanian War, the area became part of the Republic of Central Lithuania. In 1922, after a disputed election, Central Lithuania was annexed by the Second Polish Republic, and Zalavas was incorporated into the Wilno Voivodeship. Since the former Piłsudski's property had belonged to a Russian official who abandoned it, it was nationalized, and limited to the core of 65 hectares, and attached to a military base located nearby. In 1934 an association of veterans of the Polish–Soviet War purchased it from the army and a committee was created whose aim was to rebuild the manor of Marshal Piłsudski, who by then was regarded as a Polish national hero. The manor was reconstructed, and officially opened to the public as a museum on October 10, 1937. However, it was destroyed by the Soviets shortly after the Invasion of Poland in 1939. An oak and a memorial stone still mark the location of the former manor. Modern Lithuania According to the Soviet–Lithuanian Mutual Assistance Treaty of 1939, Zalavas was returned to Lithuania.
