In 1949, the Prague Jewish Community Council of the remnant Jewish community in the Czech lands ceded control of the museum to the Communist regime. On April 4, 1950, it was renamed the State Jewish Museum, a cultural institution spread over six synagogues, a ceremonial hall and a cemetery, established as "a memorial, an historic preservation agency and research institute". The Communists suppressed Judaism, forbade contact with foreign researchers, and the only exhibitions allowed were of children's drawings from Terezín. Following the Soviet invasion of 1968, few new exhibitions were held. Although the museum was Czechoslovakia's largest tourist attraction, annually drawing 700,000 visitors, the Judaica collection was known only to scholars in the field.
