of the PLO's ideology is the belief that Zionists had unjustly expelled the Palestinians from Palestine and established a Jewish state in place under the pretext of having historic and Jewish ties with Palestine. The PLO demanded that Palestinian refugees be allowed to return to their homes. This is expressed in the National Covenant: Article 2 of the Charter states that ″Palestine, with the boundaries it had during the British mandate, is an indivisible territorial unit″, meaning that there is no place for a Jewish state. This article was adapted in 1996 to meet the Oslo Accords. Article 20 states: ″The Balfour Declaration, the Mandate for Palestine, and everything that has been based upon them, are deemed null and void.

Around 50,000 (ca 1%) of the 4.6 million Palestinians in the occupied Palestinian territories (OPT) are Palestinian Christian. Under President Arafat, the Fatah-dominated Palestinian Authority adopted the 2003 Amended Basic Law, which stipulates Islam as the sole official religion in Palestine and the principles of Islamic sharia as a principal source of legislation. The draft Constitution contains the same provisions. The draft Constitution was formulated by a Constitutional Committee, established by Arafat in 1999 and endorsed by the PLO. Organization Structure The PLO incorporates a range of generally secular ideologies of different Palestinian movements "committed to the struggle for Palestinian independence and liberation," hence the name of the organization. It's formally an umbrella organization that includes "numerous organizations of the resistance movement, political parties, and popular organizations." From the
