American League for a Free Palestine
American League for a Free Palestine (ALFP) was created in July 1944, by Peter H Bergson (formerly Hillel Kook), for the purpose of supporting and funding his Hebrew Committee of National Liberation in Palestine. The ALFP attracted Jewish and non-Jewish members from all occupations, but especially those in politics and entertainment. The ALFP’s most notable achievement was the work of award winning playwright and director Ben Hecht, a member of the league. Hecht wrote A Flag is Born to propagandize the cause by comparing the fight for a free Palestine against the British to the American Revolution. With money raised from the production of the play, the league purchased a boat for the aliyah of Holocaust survivors from France. The group dissolved in December 1948 as the goal of the league had been achieved.
