Original sentence: As agreed by the Allies at the Potsdam Conference, northern Prussia, including Königsberg, was annexed by the USSR, which attached it to the Russian SFSR.Briefly Russified as Kyonigsberg (Кёнигсберг), it was renamed "Kaliningrad" in 1946 in honour of Soviet leader Mikhail Kalinin.In 1946, the city's name was changed to Kaliningrad.In the Final Settlement treaty of 1990, Germany renounced all claim to it, but without specifically transferring its former title to any other party.It is now the capital of Russia's Kaliningrad Oblast, an exclave bordered in the north by Lithuania and in the south by Poland.Its German population was expelled, and the city was repopulated with Russians and others from the Soviet Union.Many people fled from Königsberg ahead of the Red Army's advance after October 1944, particularly after word spread of the Soviet atrocities at Nemmersdorf.The Potsdam Agreement placed it provisionally under Soviet administration, but did not mention an explicit right of annexation.The city was heavily damaged by Allied bombing in 1944 and during the Battle of Königsberg in 1945; it was then captured and occupied by the Soviet Union on 9 April 1945.There has been some discussion of the territory's current legal status, although this is largely academic.These survivors, mainly women, children and the elderly, plus a few others who had returned immediately after the fighting ended, were held as slave labourers until 1949
