The Committee was instrumental in organizing and implementing the Jewish aliyah efforts to British Mandate for Palestine , and from mid May 1948 , to the newly formed State of Israel . The workers of CKŻP registered 86,000 survivors in January 1946 from across the prewar Polish Second Republic . By the end of summer , the number Jews who signed up had risen to about 205,000 – 210,000 ( 240,000 registrations with over 30,000 duplicates ) . Well over 100,000 refugees ( or , about 180,000 according to Engel ) , many with working knowledge of Yiddish , came to PRL from the Soviet Union thanks to a Polish – Soviet repatriation agreement . Gen. Spychalski signed a decree allowing them to leave Poland without visas or exit permits . Poland was the only Eastern Bloc country to do so . By the spring of 1947 , helped by CKŻP over 150,000 Jews emigrated ( additional number , outside of that period ) . To secure their release , CKŻP collected group testimonies , nevertheless , the Polish decree was easily approved by the Kremlin , seeking to undermine the British influence in the Middle East . The emigration of Jews ( known as Berihah ) was motivated by the destruction of Jewish life in Poland and anti-Jewish violence in Poland in which Poles killed Jewish Holocaust survivors , the best known incident being the Kielce pogrom
