Jews, largely Holocaust survivors, sailing for Palestine aboard the SS Exodus in 1947. A Flag is Born was produced to support such migrants.
A Flag is Born was produced by the pro-Zionist American League for a Free Palestine (ALFP) to raise financial and political support for Zionist causes, including the transport of Jews from Europe. The ALFP was entirely open about its political motivations—publicity materials read: "'A Flag is Born' is not ordinary theatre. It was not written to amuse or beguile. 'A Flag is Born' was written to make money—to make money to provide ships to get Hebrews to Palestine ... and [to] arouse American public opinion to support the fight for freedom and independence now being waged by the resistance in Palestine.
