حركة القوميين العرب
Yasser Abed Rabbo started his political career in the Arab Nationalist Movement (ANM), a pan-Arabist organization. When the Palestinian branch of the ANM evolved in 1967 into the Popular Front for the Liberation of Palestine (PFLP), he became one of its leaders. In 1968, a leftist faction of the PFLP led by Nayef Hawatmeh split from the movement and formed the Democratic Front for the Liberation of Palestine (DFLP). Abed Rabbo became a member of the DFLP's politburo and was the organization's second most influential figure, after Hawatmeh. He became the most senior member of the DFLP to serve on the Palestine Liberation Organization's executive councils.
