ABSTRACT
The Mossad le-Aliyah Bet was founded in the late 1930s to circumvent the official immigration ceilings set by the British and to bring young pioneers to Palestine illegally. Beginning in May 1939, the Mossad, run jointly by Hehalutz and the Haganah, sought to breach the British White Paper policy, which severely restricted and ultimately banned Jewish immigration. The organization was headed by Shaul Avigur (Meirov), who was also a member of the national staff of the Haganah.
