After Sovietization, all Zionism-related activities including those of cultural nature that were carried out in Hebrew were banned. In the early 1920s a few hundred Mountain Jewish families from Azerbaijan and Dagestan left for Israel and settled in Tel-Aviv. The next aliyah did not take place until the 1970s, after the ban on Jewish immigration to Israel was lifted (see: Refusenik (Soviet Union)). Between 1972 and 1978 around 3,000 people left Azerbaijan for Israel. 1970 was the demographic peak for Azerbaijani Jews after World War II; according to the census, 41,288 Jews resided in Azerbaijan that year.
