Aliyah Bet
"Aliyah Bet" is the illegal entrance to the land of Israel under the British Mandate's laws, including during World War II and the Holocaust. "Aliyah Bet" was organized by the Yishuv (the Jewish settlement in the land of Israel before Israel's establishment as a country) from 1934 until the State of Israel began in 1948. "Aliyah Bet" was carried out by the Mossad Le'aliyah Bet, a branch of the Jewish Defense Association (Haganah), the para-military organization that was to become the Israeli Defense Force (IDF). During "Aliyah Bet" 's 14 years of activity, 115,000 Jews made "Aliyah" to the land of Israel.
