With the end of the war in 1945 , the partly depopulated area was transferred to Poland under border changes promulgated at the Potsdam Conference . The surviving German population of Soldin was forcibly expelled and the town , renamed Myślibórz , was gradually repopulated by Polish settlers . It was a powiat centre initially in Szczecin Voivodeship ( 1945-1975 ) , then in Gorzów one ( 1975-1998 ) , finally in West Pomeranian one since 31 December 1998
