The Palestine Mujahidin and Martyrs Fund was established in 1964 by Fatah to recompense the families of dead and wounded militants.[8] In 1971 it was replaced by the Society for the Care of Palestinian Martyrs and Prisoners. The Society defined as "military martyrs" not only as Palestinian fedayeen killed during terrorist operations but to include fedayeen who died of natural causes while on active service. Their families received cash stipends.
