Israeli–Palestinian Conflict

The conflict combines rival national projects with recurring disputes over land, borders, Jerusalem, refugees, settlements, security, recognition, resources, and Palestinian statehood. Since 1948, it has also involved Israel's relations with neighboring Arab states and with Palestinian organizations and governing institutions.[1][5]

Its principal forms have included interstate war, Palestinian uprisings, terrorist attacks, Israeli military and security measures, and repeated diplomatic initiatives. Partition proposals and the Oslo framework created territorial or interim arrangements, but no comprehensive final-status agreement has resolved the central issues.[3][6]

The conflict is rooted in the late nineteenth century, when two distinct national movements — Zionism and Palestinian Arab nationalism — began asserting claims to the same territory.[1] The First Zionist Congress, convened in Basel on August 29, 1897, under Theodor Herzl's leadership, defined the World Zionist Organization's objective as "the creation of a home for the Jewish people in Palestine."[7] The movement drew energy from widespread antisemitism and violent pogroms across Europe, presenting emigration to the historic Jewish homeland as a durable response to the persecution of Jewish communities.[3]

By 1914, approximately 85,000 Jews lived in Palestine, including around 35,000 recent immigrants.[7] Their arrival contributed to a sharpening Palestinian Arab national consciousness and heightened anxieties over demographic and political change. The two communities increasingly understood themselves as competing for the same land, which each regarded as its homeland — called Falastin in Arabic and Eretz Yisrael in Hebrew.[7][8]

The First World War proved decisive for the conflict's structure. On November 2, 1917, British Foreign Secretary Arthur James Balfour wrote that His Majesty's Government viewed favorably "the establishment in Palestine of a national home for the Jewish people," while stipulating that nothing should prejudice the civil and religious rights of existing non-Jewish communities.[7] Britain received the Mandate for Palestine at the 1920 San Remo Conference; the League of Nations formally recognized the mandate in 1923, incorporating the Balfour Declaration and requiring Britain to facilitate Jewish immigration and settlement.[7] The arrangement amounted to a "dual obligation," because Britain was expected simultaneously to support a Jewish national home and to govern a territory with an Arab majority.[7] Palestine was administered by Britain under the League of Nations Mandate from 1922 until 1948.[1]

In practice, the conflict operates through both force and negotiation. Armed phases have included wars, intifadas, cross-border attacks, terrorism, rocket fire, and Israeli reprisals or larger military campaigns; diplomacy has included partition proposals, armistices, land-for-peace formulas, interim self-government, and two-state negotiations.[3][9]

The Oslo system illustrates the negotiated side: authority was transferred incrementally to the Palestinian Authority, while Jerusalem, refugees, settlements, security, borders, and neighboring relations were deferred.[10][6] The division between Hamas-controlled Gaza and Palestinian Authority administration in parts of Judea and Samaria has further complicated the implementation of any agreement.[3][7]

Tensions between the Jewish and Arab communities under British rule intensified through the 1920s and 1930s as Jewish immigration grew and Palestinian Arab resistance hardened. The crisis came to a head with the Arab Revolt of 1936–1939, characterized by one account as the first intifada of the Arab-Jewish conflict.[11] The revolt began with mass demonstrations and a general strike coordinated by the Arab Higher Committee, motivated by rising Jewish immigration, Palestinian Arab national consciousness, fears of demographic and political domination, and opposition to the British Mandate.[3] The general strike lasted six months, prompting Britain to dispatch an additional 20,000 troops and appoint the Peel Commission.[7]

In 1937, the Peel Commission concluded that Arab and Jewish national aspirations were irreconcilable under the mandate framework and issued the first official recommendation to partition Palestine into separate Jewish and Arab states.[11][3] Britain suppressed the revolt by 1939 through military force, widespread destruction, and collective punishment. Approximately ten percent of the Palestinian male population was reported killed, wounded, imprisoned, or exiled during the uprising.[7] The 1939 White Paper then limited Jewish immigration to 75,000 people over five years and proposed an independent unitary state within ten years, severely restricting Jewish refuge from Nazi persecution on the eve of the Second World War.[7]

The Peel Commission's partition recommendation was the first of two major partition proposals produced during this era.[3] British recruitment and training of approximately 15,000–20,000 Jews into the Palestine Police during the revolt created an organizational foundation that later contributed to the formation of the Israel Defense Forces.[11]

After World War II, Britain referred the Palestine question to the newly formed United Nations. On November 29, 1947, the UN General Assembly adopted Resolution 181 (II) by a vote of 33 in favor, 13 opposed, and 10 abstentions, recommending partition into a Jewish state and an Arab state, with Jerusalem and Bethlehem under a special international regime.[7] The proposed Jewish state comprised approximately 55 percent of Palestine and included about 500,000 Jews and 400,000 Arabs, while the proposed Arab state was almost entirely Arab.[7] Jewish leaders accepted the plan; Arab states and Palestinian representatives rejected it as favorable to the Jews and unfair to the Arab population.[3][12]

Fighting began immediately after the partition vote as a civil war between the Jewish and Palestinian Arab communities.[13] Israel declared independence on May 14, 1948, under David Ben-Gurion's leadership. The following day, after the British withdrawal, regular armies from Egypt, Transjordan, Syria, Lebanon, and Iraq entered the war; Saudi Arabia contributed forces under Egyptian command.[14][12] The war concluded through separate armistice agreements with Egypt in February 1949, Lebanon in March, Jordan in April, and Syria in July.[13][14]

By the armistices, Israel controlled approximately 78 percent of Mandatory Palestine — the territory allotted under the UN partition plan plus an additional 2,500 square miles.[14][7] Egypt retained the Gaza Strip, while Jordan retained and later annexed the West Bank, including the ancient Jewish regions of Judea and Samaria, and East Jerusalem. Those armistice lines remained until 1967.[14][7] The proposed Palestinian Arab state was never established.[7]

The war produced massive population displacement. Estimates range from 625,000 to 850,000 Palestinian Arabs who fled or were expelled during the fighting, forming the basis of the Palestinian refugee population.[8][15] Approximately 400,000 refugees went to Jordan, 150,000 to Lebanon and Syria, and 200,000 to Gaza.[7] Palestinians refer to the events surrounding Israel's establishment as the Nakba, meaning "catastrophe," while in Israel the conflict is commemorated as the War of Independence.[16][8]

In the years between the 1949 armistices and the next major war, Palestinian national identity continued to coalesce institutionally. Fatah was founded in Kuwait in 1959 under Yasir Arafat's leadership, providing an organizational vehicle for Palestinian armed struggle.[7] The Palestine Liberation Organization was established in 1964 during an Arab League summit in Cairo and initially advocated armed struggle as its primary method.[3] Arafat became chairman of the PLO in 1969. In 1974, the Arab summit at Rabat recognized the PLO as the sole legitimate representative of the Palestinian people; Arafat subsequently addressed the UN General Assembly, and the PLO received observer status.[7]

The period was not free of violence. Palestinian cross-border attacks and Israeli reprisals accumulated through the late 1950s and 1960s.[9] By 1967, the region was moving toward another confrontation amid Egypt's removal of the United Nations Emergency Force from Sinai, its announcement that it would close the Straits of Tiran to Israeli shipping, and escalating regional tensions.[9]

The Six-Day War, fought from June 5 to June 10, 1967, transformed the conflict's modern phase.[3] On June 5, Israel attacked Egyptian air bases and achieved air supremacy within hours.[7] Israel defeated Egypt, Jordan, and Syria and occupied the Sinai Peninsula, Gaza Strip, West Bank, East Jerusalem, and Golan Heights, bringing approximately 1.5 million Arabs under Israeli control and placing all of Mandatory Palestine under Israeli authority for the first time.[7][3] Israel subsequently incorporated 73 square kilometers into Jerusalem's municipal boundaries, including East Jerusalem and adjacent land, and later extended its legal jurisdiction over the Golan Heights.[8]

Before 1967, the primary dispute had centered on Israel's existence, relations with surrounding Arab states, and the 1948 refugee question. After the war, attention shifted toward the territories captured in 1967 and questions of Israeli military control, Palestinian self-determination, settlements, borders, security, and Jerusalem.[2][3]

UN Security Council Resolution 242, adopted on November 22, 1967, established the principal international framework for subsequent peace efforts.[9][7] It called for Israeli withdrawal from "territories occupied in the recent conflict" in exchange for termination of belligerency, recognition of every state's sovereignty and political independence, and the right to live in peace within secure and recognized boundaries.[9][7] It also called for a just settlement of the refugee problem and freedom of navigation.[7] A continuing dispute arose over whether its language required withdrawal from all or only some of the territories occupied.[9][7]

After two decades of Israeli military administration in the West Bank and Gaza, Palestinian frustration produced a popular uprising. The First Intifada began on December 8, 1987, after an Israeli civilian truck collided with a vehicle near the Jabaliya refugee camp in Gaza, killing four Palestinians. Riots followed immediately and spread throughout Gaza and the West Bank.[17][18] The Arabic word intifada means an uprising or literally a "shaking off."[2] The initially spontaneous movement developed into an organized rebellion involving protests, civil disobedience, and attacks on Israeli troops and civilians.[18]

The uprising increased pressure for a political solution and brought new Palestinian leadership in the West Bank and Gaza to the foreground.[18] During the intifada, the PLO affirmed Resolution 242, recognized Israel, renounced terrorism, and called for a Palestinian state in the West Bank and Gaza.[7] The 1991 Madrid Peace Conference, co-sponsored by the United States and Soviet Union, then brought Israel, Arab states, and Palestinian representatives into bilateral and multilateral negotiations.[3] The uprising had petered out by 1990, while the diplomatic developments it helped foster culminated in the 1993 Oslo process.[18][6]

Secret Israeli-Palestinian negotiations began in Oslo in December 1992 and produced a landmark agreement.[19] On September 9, 1993, Israel and the PLO exchanged letters of mutual recognition: the PLO recognized Israel's right to exist in peace and security and renounced terrorism, while Israel recognized the PLO as the representative of the Palestinian people.[6] Four days later, Israeli Prime Minister Yitzhak Rabin and PLO negotiator Mahmoud Abbas signed the Declaration of Principles on Interim Self-Government Arrangements at the White House.[19]

The declaration defined its objective as establishing a Palestinian Interim Self-Government Authority for a transitional period "not exceeding five years," leading to a permanent settlement based on UN Security Council Resolutions 242 and 338.[10] It provided for incremental Israeli withdrawal from Palestinian population centers as authority was transferred to a Palestinian Authority.[6] Jerusalem, refugees, settlements, security arrangements, borders, and relations with neighboring countries were reserved for permanent-status negotiations.[10]

The May 1994 Cairo Agreement finalized Israel's withdrawal from most of Gaza and Jericho.[19] Oslo II, signed at Taba in September 1995, divided the West Bank into Area A under Palestinian administrative and security control, Area B under Palestinian administration with Israeli security responsibility, and Area C under Israeli military responsibility.[8][19] The January 1997 Hebron Protocol transferred most of Hebron to Palestinian control, and the October 1998 Wye Memorandum called for further Israeli withdrawals.[19] By September 2000, the Palestinian Authority controlled more than 85 percent of Gaza and 39.7 percent of the West Bank, with 99 percent of the Palestinian population under its jurisdiction.[6]

Palestinian terrorist groups attacked Israeli civilian targets throughout the interim period, undermining Israeli support for the agreements.[6] In November 1995, Prime Minister Rabin was assassinated by Yigal Amir, an Israeli opponent of the accords on religious grounds. Hamas attacks further eroded support for Israel's Labor Party.[6] At the July 2000 Camp David summit, President Bill Clinton, Prime Minister Ehud Barak, and PLO Chairman Yasir Arafat failed to agree on borders, Jerusalem, and the Palestinian refugee issue.[19] The Oslo timetable did not produce a final-status agreement, although it created the Palestinian Authority and established direct Israeli-Palestinian negotiations as a primary diplomatic framework.[6]

Riots erupted following Likud leader Ariel Sharon's September 28, 2000, visit to the Temple Mount compound in Jerusalem, and the unrest escalated into the Second Intifada, or al-Aqsa Intifada.[19][20] Palestinians attributed the outbreak primarily to Sharon's visit, while Israeli leaders argued that the violence had been prepared or orchestrated by Palestinian leaders and pointed to violence preceding the visit.[20]

The uprising developed into sustained attacks against Israeli civilians, including suicide bombings, shootings, and rocket attacks.[20] By summer 2003, approximately 2,400 Palestinians and 800 Israelis had been killed, with thousands more wounded.[7] Palestinian security forces participated in the violence, and Hamas carried out suicide bombings targeting Israeli civilians.[7] Israel responded with military operations in Palestinian areas, reimposed a military presence in zones transferred to Palestinian Authority control, and began constructing a security barrier intended to prevent terrorists from reaching Israeli population centers.[20][7] The uprising later petered out amid Palestinian exhaustion, Israeli military operations, and the barrier's disruption of terrorist attacks.[20]

In 2005, Israel completed a unilateral disengagement from the Gaza Strip, removing approximately 8,000 Jewish settlers and dismantling its military installations there.[3][7] Despite the withdrawal, Israel retained control of Gaza's airspace and land and maritime access points.[21]

Hamas won the January 2006 Palestinian legislative election, defeating Fatah and producing a major internal Palestinian political crisis.[22] In June 2007, Hamas seized Fatah bases in Gaza during violent clashes and established effective control over the territory.[3][7] Mahmoud Abbas dismissed the Hamas-led government and reorganized the Palestinian Authority to govern parts of the West Bank, while Israel and Egypt tightened controls on goods and people transiting Gaza.[21][7]

The result was a political and geographic division between Hamas rule in Gaza and Palestinian Authority administration in parts of Judea and Samaria.[3][7] Hamas carries out terrorist attacks, has longstanding ties to Iran, and has developed tunnels used for weapons smuggling and attacks.[22] Major Israel-Hamas conflicts followed in 2008–2009, 2012, 2014, and 2021, each causing significant casualties and damage in Gaza.[23]

On October 7, 2023, Hamas-led terrorists launched a coordinated surprise attack from Gaza into southern Israel amid a massive rocket barrage.[24] Approximately 1,200 people were killed, and more than 250 were taken hostage into Gaza.[24] The attack became a defining escalation in the broader Israeli-Palestinian conflict and initiated a major Israel-Hamas war.[3]

Israel declared war and launched an air and ground campaign against Hamas. A ground offensive began on October 28, 2023, with the stated aims of destroying Hamas's military infrastructure and securing the hostages' release.[25] The Office of the Director of National Intelligence assessed in February 2024 that Iranian leaders had not orchestrated the attack and had no foreknowledge of it, although Iran had long provided Hamas with material support.[23]

The attack and ensuing war intensified disputes over security, hostages, civilian protection, humanitarian access, Gaza's future governance, Hamas's military and political role, and the possibility of renewed diplomacy.[26] Gaza-war casualty figures vary by source and methodology; figures attributed to the Hamas-run Gaza Health Ministry are not independently verifiable in the cited reporting and should not be treated as uncontested totals.[26]

The Palestinian refugee issue has been a central obstacle to resolving the conflict since 1948. The displacement of between 625,000 and 850,000 Palestinian Arabs during the War of Independence — estimates vary by source — created a refugee population whose status remained unresolved through subsequent negotiations.[8][15] Accounts also differ over causation: a Palestinian account emphasizes forced expulsion by Israeli forces, while an Israeli account emphasizes wartime flight encouraged by Arab leaders during a war Israel did not initiate.[8]

More than four million Palestinian refugees and descendants live in the West Bank, Gaza, Jordan, Lebanon, and Syria.[2] The United Nations Relief and Works Agency for Palestine Refugees in the Near East is mandated by the UN General Assembly to provide protection and services to registered refugees.[21] The parties disagree over return, resettlement, responsibility, and compensation.[2] Palestinian representatives have demanded a "right of return" to present-day Israel; Israel has rejected that demand as formulated, arguing that it would threaten Israel's character as a Jewish state.[6][4]

The Oslo agreements deferred the core permanent-status agenda. Issues recorded in Israeli-Palestinian agreements include borders, Jerusalem, Israeli settlements, Palestinian refugees, security arrangements, military sites, archaeological findings, water rights, Israelis living under potential Palestinian sovereignty, and Palestinian foreign relations.[5]

Jerusalem is among the most symbolically charged disputes. Israeli governments have maintained that Jerusalem is Israel's united capital, while Palestinians claim East Jerusalem as the capital of a future Palestinian state. The city's significance to Judaism, Islam, and Christianity — and the sensitivity of the Temple Mount compound — have made it one of the hardest issues to negotiate.[2]

Israeli settlement construction in Judea and Samaria has continued during the post-Oslo period. Palestinian negotiators argue that settlement growth undermines the prospects for a viable Palestinian state.[4]

Proposed final-settlement frameworks generally include an independent Palestinian state alongside Israel, based broadly on the pre-June 1967 lines with reciprocal territorial exchanges, combined with negotiated arrangements for Jerusalem, refugees, and security.[4][7] On November 29, 2012, the UN General Assembly accorded Palestine non-member observer-state status and reaffirmed a two-state framework based on the pre-1967 borders.[7] A single binational state is another proposal, but it raises a conflict between Israel's Jewish identity, democratic character, and demands for equal political rights.[4]

Disagreement over the desired outcome and deep mutual distrust remain recurring obstacles.[4] The political division between Hamas-controlled Gaza and the Fatah-led Palestinian Authority in parts of the West Bank creates a further complication: any agreement must address which Palestinian body has the authority to conclude and implement it.[4]

The Oslo framework focused on Palestinians in the West Bank and Gaza and did not recognize the Palestinian Arab minority within Israel as a party to the negotiations.[27] Research from Ben-Gurion University describes a dual response among Israel's Arab citizens after Oslo: a localized political struggle for equal rights as a national indigenous minority within Israel, alongside continued support for Palestinian national rights, self-determination, and a two-state solution. The research also records a shift toward voting for Arab rather than Zionist parties.[27]

The conflict has redrawn borders, produced large refugee populations, and created institutions that continue to structure Israeli and Palestinian politics. The 1967 war moved territorial control, settlements, borders, security, and Jerusalem to the center of the dispute, while Oslo created the Palestinian Authority without resolving final status.[3][6]

The later division between Hamas-controlled Gaza and Palestinian Authority administration in parts of Judea and Samaria fragmented Palestinian governance.[3][7] The conflict remains a defining feature of Israeli society and a major subject of regional diplomacy, international debate, and Jewish and Palestinian national identity.[2]

The conflict's origins, causation, terminology, and legal framing are interpreted differently across Israeli and Palestinian narratives.[13][8] These disagreements concern both specific events and the broader moral and political meaning assigned to them.

The 1948 war illustrates the depth of divergence. In Israel, it is commemorated as the War of Independence — a war of survival in which the newly established state fought Arab armies that rejected the UN partition plan and entered the conflict after Israel's May 14 declaration.[13][3] Palestinians refer to the same period as the Nakba, emphasizing the displacement of hundreds of thousands and the destruction of Palestinian communal life.[16][8] Even the scale of displacement is disputed: Israeli-oriented sources record 625,000–675,000 displaced people, while Palestinian-oriented sources cite 700,000–850,000.[8]

The causes and immediate triggers of the intifadas are similarly contested. Palestinian accounts attribute the Second Intifada primarily to Ariel Sharon's Temple Mount visit, while Israeli accounts contend that Palestinian leaders had prepared or orchestrated violence before the visit.[20][21] Responsibility for Oslo's collapse is also disputed: the State Department account notes that explanations of the 2000 Camp David failure differ and records that President Clinton blamed Arafat.[19]

The legal and political status of territory captured in 1967 — including the West Bank, East Jerusalem, Gaza, and Israeli settlements — remains disputed.[9] Israelis and Arabs have also disagreed over whether Resolution 242 required withdrawal from all territories or only some.[9][7] The characterization of Palestinian armed organizations, Israeli military measures, and the October 7 attack is likewise contested in political and legal discourse.[20][26]
