evidence: Territories of the former Russian Empire that permanently or temporarily became independent: [...] In late 1945, Soviet Russia annexed the northern border strip of the Masurian District (current southern border strip of Kaliningrad Oblast) with the towns of Gierdawy (now Zheleznodorozhny) and Iławka (now Bagrationovsk) from Poland and expelled the already formed local Polish administration.[21] [...] Meanwhile, territories were removed from the Russian SFSR, including Turkmenistan and Uzbekistan in 1924, Kazakhstan and Kyrgyzstan in 1936, and Karelo-Finland from 1945 to 1956. The Crimean oblast and city of Sevastopol were transferred to Ukraine on 19 February 1954 (later annexed by the Russian Federation in 2014).
