Following the defeat of Nazi Germany , border changes promulgated at the Potsdam Conference assigned the town to Poland , and its German population was expelled . The first expulsion of the surviving German inhabitants took place on 17 October 1945 , followed by a series of further expulsions beginning on 17 August 1946 . In 1949 only about 70 Germans were left in the town . In 1946 – 47 , the town was repopulated with Poles and Lemkos , who partly came from what had been eastern Poland but was annexed by the Soviet Union . The town was given the Polish name Dyrłów , and later Darłów , before changing to the current name
