Fedayeen groups began joining the Palestine Liberation Organization (PLO) in 1968. While the PLO was the "unifying framework" under which these groups operated, each fedayeen organization had its own leader and armed forces and retained autonomy in operations. Of the dozen or so fedayeen groups under the PLO framework, the most important were the Popular Front for the Liberation of Palestine (PFLP) headed by George Habash, the Democratic Front for the Liberation of Palestine (DFLP) headed by Nayef Hawatmeh, the PFLP-General Command headed by Ahmed Jibril, as-Sa'iqa (affiliated with Syria), and the Arab Liberation Front (backed by Iraq).
