Bricha

'escape, flight'), also called the Bericha Movement,[1] was the underground organized effort that helped Jewish Holocaust survivors escape Europe post-World War II to the British Mandate for Palestine in violation of the White Paper of 1939.

In late 1944 and early 1945, Jewish members of the Polish resistance met up with Warsaw ghetto fighters in Lubin to form Bricha as a way of escaping the antisemitism of Europe, where they were convinced that another Holocaust would occur.

Almost immediately, the explicitly Zionist Berihah became the main conduit for Jews coming to Palestine, especially from the displaced person camps, and it initially had to turn people away due to too much demand.

Using ships supplied at great cost [citation needed] by the Mossad Le'aliyah Bet, then the immigration arm of the Yishuv, these refugees were then smuggled through the British cordon around Palestine.

Bricha was part of the larger operation known as Aliyah Bet, and ended with the establishment of Israel, after which immigration to the Jewish state was legal, although emigration was still sometimes prohibited, as happened in both the Eastern Bloc and Arab countries (see for example refusenik).
