Aliyah Bet

Aliyah Bet (Hebrew: 'עלייה ב‎, "Aliyah 'B'" - bet being the second letter of the Hebrew alphabet) was the code name given to illegal immigration by Jews to the British Mandate for Palestine in violation of British White Paper of 1939 restrictions, in the years 1934-1948. In modern day Israel it has also been called by the Hebrew term Ha'apala (Hebrew: ההעפלה‎; ascension). The Aliyah Bet is distinguished from the Aliyah Aleph ("Aliyah 'A'", Aleph being the first letter of the Hebrew alphabet): the limited Jewish immigration permitted by British authorities in the same period.
