In June 1940, Lithuania was occupied by the Soviet Union. The Soviets introduced harsh sovietization policies, including nationalization of larger enterprises, landholdings, and real estate.[5] Opponents of communism and the new regime were persecuted: an estimated 6,600 were imprisoned as "enemies of the people"[6] and another 17,600 deported to Siberia.[7] The Lithuanian Army was reorganized into the 29th Rifle Corps (179th Rifle and 184th Rifle Divisions) of the Red Army.
