The Palestine Liberation Organization (PLO; Arabic: منظمة التحرير الفلسطينية Munaẓẓamat at-Taḥrīr al-Filasṭīniyyah) is a Palestinian nationalist coalition that is internationally recognized as the official representative of the Palestinian people in both the Palestinian territories and the diaspora. It is currently represented by the Palestinian Authority based in the West Bank city of Al-Bireh. Founded in 1964, it initially sought to establish an Arab state over the entire territory of the former Mandatory Palestine, advocating the elimination of Israel.
