Palestine (Arabic: فلسطين, romanized: Filasṭīn), also known as the State of Palestine (دولة فلسطين, Dawlat Filasṭīn), is a de jure sovereign state in Western Asia. The Palestine Liberation Organization (PLO) governs it and claims the West Bank and Gaza Strip. However, Israel has occupied its claimed territory since the 1967 Six-Day War; the West Bank is currently divided into 165 Palestinian enclaves under partial Palestinian National Authority (PNA) civil rule, and 230 Israeli settlements into which Israeli law is "pipelined," while Gaza is ruled by Hamas and has been subject to a long-term blockade by Egypt and Israel since 2007.
Following World War II, the United Nations (UN) issued a Partition Plan for Mandatory Palestine in 1947, which advocated for the establishment of autonomous Arab and Jewish nations as well as an internationalized Jerusalem. The Jews supported the Partition Plan, while the Arabs opposed it. A civil war erupted out shortly after the United Nations General Assembly accepted the proposal as Resolution 181, and the plan was never executed. On the 14th of May 1948, the day following Israel's independence, neighboring Arab nations invaded the former British Mandate and battled Israeli troops in the First Arab–Israeli War. The Arab League then formed the All-Palestine Government on September 22, 1948, to manage the All-Palestine Protectorate in the Egyptian-occupied Gaza Strip. Except for Transjordan, which had invaded and then annexed the West Bank, including East Jerusalem, it was quickly recognized by all Arab League members. Though the All-Palestine Government's stated authority included the whole former Mandatory Palestine, its practical jurisdiction was restricted to the Gaza Strip. During the Six-Day War in June 1967, Israel gained the Gaza Strip and the Sinai Peninsula from Egypt, the West Bank and East Jerusalem from Jordan, and the Golan Heights from Syria.
Yasser Arafat, then-PLO Chairman, declared the foundation of the State of Palestine on November 15, 1988, in Algiers. A year after the Oslo Accords were signed in 1993, the PNA was founded to manage (to varied degrees) regions A and B in the West Bank, which included 165 enclaves, as well as the Gaza Strip. Following Hamas's victory as the dominant party in the PNA parliament in the most recent elections (2006), a dispute erupted between it and the Fatah party, resulting in Hamas's takeover of Gaza in 2007. (two years after the Israeli disengagement).
As of February 2020, the population of Palestine was 5,051,953, ranking it 121st in the world. Although Palestine claims Jerusalem as its capital, the city is under Israeli sovereignty; the international community does not accept either Palestine's or Israel's claims to the city. The State of Palestine has been recognized by 138 of the 193 UN members and has been a non-member observer state in the UN since 2012. Palestine is a member of the Arab League, the Organization of Islamic Cooperation, the Group of 77, the International Olympic Committee, UNESCO, UNCTAD, and the International Criminal Court, among other organizations.
