In 1939 the town had 736 inhabitants . Nida became nearly uninhabited , like all of the Curonian Spit , as a result of the Red Army advance and the Evacuation of East Prussia at the end of World War II , and the eventual expulsion of surviving German inhabitants . The town was reassigned to Lithuania under border changes promulgated at the Potsdam Conference , and became part of the Lithuanian SSR within the Soviet Union ; since 1990 it has been part of independent Lithuania
