United Nations Partition Plan for Palestine in the context of "Two-state solution"

Israel, officially the State of Israel, is a country in the Southern Levant region of West Asia. It borders Lebanon to the north, Syria to the northeast, Jordan to the east and Egypt to the southwest. Israel occupies the Palestinian territories of the West Bank in the east and the Gaza Strip in the southwest, as well as the Syrian Golan Heights in the northeast. Israel's western coast lies on the Mediterranean Sea, the southern tip reaches the Red Sea, and the east includes the Earth's lowest point near the Dead Sea. Jerusalem is the government seat and proclaimed capital, while Tel Aviv is Israel's largest urban area and economic centre.

The Land of Israel is synonymous with Palestine or the Holy Land. In antiquity it was home to the Canaanites and later the kingdoms of Israel and Judah. Its location at a continental crossroads brought demographic shifts under various empires. Nineteenth-century European antisemitism fuelled the Zionist movement for a Jewish homeland. Britain endorsed this goal in the 1917 Balfour Declaration and ruled Mandatory Palestine from 1920. Jewish immigration and British policies intensified Arab-Jewish tensions, and the 1947 United Nations (UN) Partition Plan led to a civil war.

Palestine, officially the State of Palestine, is a country in West Asia. It encompasses the Israeli-occupied West Bank, including East Jerusalem, and the Gaza Strip, collectively known as the Palestinian territories. The territories share the vast majority of their borders with Israel, with the West Bank bordering Jordan to the east and the Gaza Strip bordering Egypt to the southwest. It has a total land area of 6,020 square kilometres (2,320 sq mi) while its population exceeds five million. Its proclaimed capital is Jerusalem, while Ramallah serves as its de facto administrative center. Gaza was its largest city prior to evacuations in 2023.

Situated at a continental crossroad, the Palestine region was ruled by various empires and experienced various demographic changes from antiquity to the modern era. It was treading ground for the Nile and Mesopotamian armies and merchants from North Africa, China and India. The region has religious significance. The ongoing Israeli–Palestinian conflict dates back to the rise of the Zionist movement, supported by the United Kingdom during World War I. The war saw Britain occupying Palestine from the Ottoman Empire, where it set up Mandatory Palestine under the auspices of the League of Nations. Increased Jewish immigration led to intercommunal conflict between Jews and Palestinian Arabs, which escalated into a civil war in 1947 after a proposed partitioning by the United Nations was rejected by the Palestinians and other Arab nations.

The 1947–1948 civil war in Mandatory Palestine was the first phase of the 1948 Palestine war. It broke out after the General Assembly of the United Nations adopted a resolution on 29 November 1947 recommending the adoption of the Partition Plan for Palestine.

During the civil war, Palestine's Jewish and Arab communities clashed (the latter supported by the Arab Liberation Army) while the British, who had the obligation to maintain order, organized their withdrawal and intervened only occasionally.

The 1948 Palestine war was fought in the territory of what had been, at the start of the war, British-ruled Mandatory Palestine. During the war, Zionist forces conquered territory and established the State of Israel, over 700,000 Palestinians fled or were expelled from Palestine, the British withdrew from their Mandate of Palestine, and four neighbouring Arab nations entered the territory and joined the war. By the end of the war, the State of Israel had held or captured about 78% of former territory of the mandate, the Kingdom of Jordan had captured and later annexed the area that became the West Bank, and Egypt had captured the Gaza Strip. The war formally ended with the 1949 Armistice Agreements, which established the State of Israel and laid out the Green Line demarcating these territories. It was the first war of the Israeli–Palestinian conflict and the broader Arab–Israeli conflict.

The war had two main phases, the first being the 1947–1948 civil war, which began on 30 November 1947, a day after the United Nations voted to adopt the Partition Plan for Palestine, which planned for the division of the territory into Jewish and Arab sovereign states. During this period, the British still maintained a declining rule over Palestine and occasionally intervened in the violence. Initially on the defensive, the Zionist forces switched to the offensive in April 1948. In anticipation of an invasion by Arab armies, they enacted Plan Dalet, an operation aimed at securing territory for the establishment of a Jewish state.

East Jerusalem (Arabic: القدس الشرقية, romanized: al-Quds ash-Sharqiya; Hebrew: מִזְרַח יְרוּשָׁלַיִם, romanized: Mizraḥ Yerushalayim) is the portion of Jerusalem that was held by Jordan after the 1948 Arab–Israeli War, as opposed to West Jerusalem, which was held by Israel. Captured and occupied in 1967, this area was unilaterally annexed by Israel in 1980. The United Nations and other intergovernmental organizations consider East Jerusalem a part of the Palestinian territories according to international law, and under illegal occupation by Israel. Many states recognize East Jerusalem as the capital of the State of Palestine (such as Brazil, China, Russia, and all 57 members of the Organisation of Islamic Cooperation), whereas other states (such as Australia, France and others) assert that East Jerusalem "will be the capital of Palestine", while referring to it as "an occupied territory". In 2020, East Jerusalem had a population of 595,000 inhabitants, of whom 361,700 (61%) were Palestinian Arabs and 234,000 (39%) were Jewish Israelis. Israeli settlements in East Jerusalem are illegal under international law and in the eyes of the international community.

Jerusalem was envisaged as a separate, international city under the 1947 UN partition plan. It was, however, divided by the 1948 war that followed Israel's declaration of independence. As a result of the 1949 Armistice Agreements, the city's western half came under Israeli control, while its eastern half, containing the famed Old City, fell under Jordanian control, at the exception of Mount Scopus enclave. Israel occupied East Jerusalem during the 1967 Six-Day War; since then, the entire city has been under Israeli control. The 1980 Jerusalem Law declared unified Jerusalem the capital of Israel, formalizing the effective annexation of East Jerusalem. Palestinians and many in the international community consider East Jerusalem to be the future capital of the State of Palestine. The status of Jerusalem has been described as "one of the most intractable issues in the Israeli–Palestinian conflict", with conflicting claims to sovereignty over the city or parts of it, and access to its holy sites.

The Israeli–Palestinian conflict is an ongoing military and political conflict about land and self-determination within the territory of the former Mandatory Palestine. Key aspects of the conflict include the Israeli occupation of the West Bank and Gaza Strip, the status of Jerusalem, Israeli settlements, borders, security, water rights, the permit regime in the West Bank and in the Gaza Strip, Palestinian freedom of movement, and the Palestinian right of return.

The conflict has its origins in the rise of Zionism in the late 19th century in Europe, a movement which aimed to establish a Jewish state through the colonization of Palestine, synchronously with the first arrival of Jewish settlers to Ottoman Palestine in 1882. The Zionist movement garnered the support of an imperial power in the 1917 Balfour Declaration issued by Britain, which promised to support the creation of a "Jewish homeland" in Palestine. Following British occupation of the formerly Ottoman region during World War I, Mandatory Palestine was established as a British mandate. Increasing Jewish immigration led to tensions between Jews and Arabs, which grew into intercommunal conflict. In 1936, an Arab revolt erupted, demanding independence and an end to British support for Zionism, which was suppressed by the British. Eventually, tensions led to the United Nations adopting a partition plan in 1947, triggering a civil war.

The Israeli annexation of East Jerusalem, known to Israelis as the reunification of Jerusalem, refers to the Israeli occupation of East Jerusalem during the 1967 Six-Day War, and its annexation.

Jerusalem was envisaged as a separate, international city under the 1947 United Nations partition plan, but it was divided by the 1948 war that followed Israel's declaration of independence. As a result of the 1949 Armistice Agreements, the city's western half came under Israeli control, while its eastern half, containing the Old City, fell under Jordanian control. In 1950, Jordan annexed East Jerusalem as part of its larger annexation of the West Bank.
