Founded as part of the Prime Minister's office by Prime Minister Moshe Sharett in 1952–1953, Nativ was designed to function covertly, making contacts, fostering Jewish education, and aiding immigration to Israel. Nativ was not the first organization to do this; Mossad Le'aliyah Bet, part of the Haganah, had brought Jews to Israel in defiance of the British Mandate, but this ended with the creation of Israel. Nativ was to continue that mission, except now in defiance of the Soviet Union.
