Ahmad bin Yahya
If one includes Aden, there were about 63,000 Jews in Yemen in 1948. Today, there are about 200 left. In 1947, rioters killed at least 80 Jews in Aden, a British colony in southern Yemen. In 1948 the new Zaydi Imam Ahmad bin Yahya unexpectedly allowed his Jewish subjects to leave Yemen, and tens of thousands poured into Aden. The Israeli government's Operation Magic Carpet evacuated around 44,000 Jews from Yemen to Israel in 1949 and 1950. Emigration continued until 1962, when the civil war in Yemen broke out. A small community remained until 1976, though it has mostly immigrated from Yemen since. In March 2016, the Jewish population in Yemen was estimated to be about 50.
