In the years after World War II, many Jewish refugees from the Baltic Countries, Romania and Poland moved to Sweden. Following the war, the Jewish population of Stockholm alone was 7,000 including children. For example, the cartoonist Art Spiegelman was born in Stockholm, where his father Vladek Spiegelman had moved after surviving a concentration camp. In the following decades, more waves of Jewish refugees came from Hungary in 1956 and 1968 who had fled the Communist government. More refugees came then from Poland between 1968–1970. Between 1945 and 1970, the Jewish population of Sweden doubled.
