Алия Бет
The term "Aliyah Bet" is composed of the Hebrew word "Aliyah", meaning Jewish Immigration (Individual or a group) to the land of Israel, and the Hebrew Letter "Bet", the second letter in the Hebrew Alphabet. Its use was analogous to the English term "Plan B". Vis-a-vis, the illegal transportation of immigrants was being carried out simultaneously with the legal Jewish immigration to the land of Israel permitted by the British Mandate. The Mandate attempted to limit the number of immigration certificates in a way which contradicted the national goals of the Jewish community living there. "Aliyah Bet" started only modestly in the midst of the nineteen-thirties. The majority of Jewish immigrants, the Olim, arrived after World War II and the Holocaust.
