from UK Foreign Secretary
Arthur Balfour to
Walter Rothschild expressing the support of the British government for "the establishment in Palestine of a national home for the Jewish people." The Israeli–Palestinian conflict has origins in the Arab-Jewish conflict of the late 19th and early 20th centuries, with the development of political Zionism and the arrival of Zionist settlers to the
Land of Israel, or Palestine. During the early 20th century,
Arab nationalism and
Turkish nationalism also grew within the
Ottoman Empire.
World War I began in 1914, with
Great Britain and
France opposing the Ottoman Empire. To gain support from
Sharif of Mecca Hussein bin Ali, his Arab
Sharifian Army, and Arab nationalists in the war against the Ottomans, Great Britain promised in the
McMahon–Hussein correspondence that Hussein would have control of an independent state in the Arab areas of the Ottoman Empire. Palestine was "ambiguously omitted" from the Arab state. The
British Empire supplied a large amount of weapons to the
Arab revolt in 1916–1918. With support from the Arab revolt the British Empire defeated the Ottoman's forces and took control of Palestine, Jordan and Syria. It later transpired that the British and French governments had secretly made the
Sykes-Picot Agreement in 1916 that unambiguously excluded Palestine from Arab control and did not allow the formation of an independent Arab state that included it. In July 1920, the short-lived
Arab Kingdom of Syria, with Emir
Faisal (one of the leaders of the Arab revolt) as king and tolerated by Britain, was crushed by French armed forces, equipped with modern artillery. While there was a significant wave of
Jewish immigration in the late 19th century, it was not until the arrival of more
ideologically Zionist immigrants in the decade preceding the First World War that the landscape of Ottoman Palestine would start to significantly change.
Jewish land purchases and the eviction of tenant
Arab peasants would contribute to the Palestinian population's growing fear of territorial displacement and dispossession in this period, as would armed confrontations in later years. From early on, some in Zionist movement had the idea of "transferring" the Arab Palestinian population out of the land of a future Jewish state. According to the political scientist
Norman Finkelstein,
population transfer was considered as an acceptable solution to the problems of ethnic conflict until around
World War II and even for a time afterward. Transfer was considered a drastic but "often necessary" means to end an ethnic conflict or ethnic
civil war. In modern times, transfer is often seen as a euphemism for
ethnic cleansing. The idea of transfer gained support of the Zionist leadership after it was proposed by the British
Peel Commission. or as a response to violence. Israeli historian
Benny Morris wrote in 2004 that the idea of transfer was "inevitable and inbuilt into Zionism". He clarified in 2008 that it "had not been part of the original Zionist ideology" but was advocated for starting in the mid-1930s in response to the violence of the Arab Revolt. There were Arabs that feared displacement as early as the 1880s with one Zionist writing that he had been accused of coming "to drive them out."
1920s With the creation of the
British Mandate in Palestine after the end of the first world war, large-scale Jewish immigration began accompanied by the development of a separate Jewish-controlled sector of the economy supported by foreign capital. The
British colonial government in
Mandatory Palestine recognized the
Zionist organizations as legitimate and representative self-governing institutions of the Jewish population. These organizations created the structure of a
quasi state. Chief among them was the Jewish Agency for Palestine (renamed the
Jewish Agency for Israel after 1948), which would turn into the government of the local Jewish community. It was originally established in 1908 as the of the Zionist Organization (now the
World Zionist Organization). Britain and the
League of Nations gave it semi-official diplomatic status which increased the
international legitimacy of it and by extension the Zionist movement. Morris believes Palestine's Arabs in this period were characterized by a "vying coalition of clans" that setup "political parties" for "form's sake."
Amin al-Husseini, was appointed as
Grand Mufti of Jerusalem by British
High Commissioner Herbert Samuel. Husseini immediately marked the
Jewish national movement and
Jewish immigration to Palestine as the enemies of his cause. He initiated large-scale riots against the Jews as early as 1920
in Jerusalem, and in 1921
in Jaffa. Among the results of this violence was the establishment of the
Haganah Jewish paramilitary force. In 1929 a further series of violent
riots resulted in the deaths of 133 Jews and 116 Arabs, with significant Jewish casualties in
Hebron and
Safed, and the evacuation of Jews from Hebron and Gaza. Alongside political unrest, rural Palestine in the Mandate era experienced demographic and agricultural expansion. Large villages such as
Lajjun and
Hamama grew in size,
reclaimed marginal lands, and integrated into regional markets, reflecting the resilience and transformation of the Palestinian countryside during this period.
1936–1939 Arab revolt dispersing a crowd in the
Jaffa riots, seen as the start of the
Arab revolt (1936–1939) in Palestine against British rule and the mass
Jewish immigration and rapid expansion of Jewish settlements it allowed. Historians disagree about who controlled the
1936–1939 Arab revolt in Palestine. One view is it was a peasant-led
popular uprising and a
national struggle of Palestinian Arabs against British Another view is that the revolt was controlled by the Arab Higher Committee and not limited to the rural population. The revolt occurred during a
peak in the influx of European Jewish immigrants, as rural tenant farmers (referred to as in Arabic) faced growing plight and land dispossession, contributing to
rural flight and
urbanization, which eroded traditional social bonds and failed to alleviate the peasants' abject poverty. In the early 1930s, the Arab national struggle in Palestine had drawn many Arab nationalist militants from across the Middle East, such as
Sheikh Izz ad-Din al-Qassam from Syria, who established the
Black Hand militant group and had prepared the grounds for the
1936–1939 Arab revolt in Palestine. Following the death of al-Qassam at the hands of the British in late 1935, tensions erupted in 1936 into the
Arab general strike and general boycott. The strike soon deteriorated into violence, and the Arab revolt was repressed by the British armed forces with assistance from auxiliary units of the
Palestine Police Force (the
Jewish Settlement Police, the
Jewish Supernumerary Police, and the
Special Night Squads). Palestinian historian
Rashid Khalidi estimates suppression of the revolt left at least 10% of the adult male population killed, wounded, imprisoned or exiled. Other estimates of deaths caused by suppression of the revolt are lower, with official British figures and several Israeli historians viewing many of the Arab deaths in this period as attributable to other causes. Between the expulsion of much of the Arab leadership and the weakening of the economy, the Palestinians would struggle to confront the growing Zionist movement. The cost and risks associated with the revolt and the ongoing
inter-communal conflict led to a shift in British policies in the region and the appointment of the
Peel Commission which recommended creation of a small Jewish country, which the two main Zionist leaders,
Chaim Weizmann and
David Ben-Gurion, accepted. Both of their writings indicated they thought that if they accepted a small state it would expand later. The subsequent
White Paper of 1939, which rejected a Jewish state and sought to limit Jewish immigration to the region, was the breaking point in relations between British authorities and the Zionist movement.
1940–1947 ship
Jewish State carrying illegal Jewish immigrants from Europe at the
Haifa Port,
Mandatory Palestine, 1947 Renewed violence, which continued sporadically until the beginning of World War II, ended with around 5,000 casualties on the Arab side and 700 casualties combined on the British and Jewish sides in total. With the eruption of
World War II, the situation in Mandatory Palestine calmed down. In this period, there was a shift towards a more moderate stance among Palestinian Arabs under the leadership of the
Nashashibi clan. Even a joint Jewish–Arab
Palestine Regiment was established, under British command, that fought against Nazi German troops in North Africa. The more radical exiled al-Husseini faction, however, tended to cooperate with Nazi Germany. It participated in the establishment of pro-Nazi propaganda machinery throughout the Arab world. The
defeat of Arab nationalists in Iraq and subsequent relocation of al-Husseini to Nazi-occupied Europe tied his hands regarding field operations in Palestine, though he regularly demanded that the Italians and the Germans
bomb Tel Aviv. By the end of World War II, a crisis over the fate of
Holocaust survivors from Europe led to renewed tensions between the
Yishuv and Mandate authorities. By 1944, Jewish groups began to conduct military-style operations against the British, with the aim of persuading Great Britain to accept the formation of a Jewish state. This culminated in the
Jewish insurgency in Mandatory Palestine. The sustained Zionist paramilitary campaign against the British authorities, along with diplomatic damage and worldwide negative publicity from treating Jewish refugees as illegal immigrants, were major factors in the British decision to leave. To decide what to do next, the
United Nations Special Committee on Palestine was established which recommended partition and the
End of the British Mandate for Palestine.
1948 Palestine war The 1948 Palestine war refers to the first stage
1947–1948 civil war in Mandatory Palestine and the second stage
1948 Arab–Israeli War. The preceding civil war is also sometimes included by those referring to the 1948 Arab–Israeli War.
1947 United Nations partition plan and civil war On 29 November 1947, the
General Assembly of the United Nations adopted
Resolution 181(II) that recommending the adoption and implementation of a plan to partition Palestine into an Arab state, a Jewish state and an international City of Jerusalem. Palestinian Arabs were opposed to the partition. Palestinian Jews accepted the partition but began to think in terms of expanding Israel's borders beyond what was allocated to it by the UN. One leader said they would capture more territory if a war was launched against them. On the next day,
Palestine was swept by violence, igniting the 1947–1948 civil war in Mandatory Palestine. For four months, under continuous Arab provocation and attack, the Yishuv was usually on the defensive while occasionally retaliating. The
Arab League helped the Palestinian Arabs' struggle by forming the volunteer-based
Arab Liberation Army and supporting the Palestinian Arab
Holy War Army, under the leadership of
Abd al-Qadir al-Husayni and
Hasan Salama. On the Jewish side, the civil war was managed by the major underground militias – the
Haganah,
Irgun and
Lehi – strengthened by numerous Jewish veterans of World War II and foreign volunteers. By spring 1948, it was already clear that the Arab forces were nearing a total collapse, while Yishuv forces gained more and more territory, creating a large scale
refugee problem of Palestinian Arabs.
1973 Yom Kippur War On 6 October 1973, a coalition of Arab forces consisting of mainly Egypt and Syria launched a surprise attack against Israel on the Jewish holy day of Yom Kippur. Despite this, the war concluded with an Israeli victory, with both sides suffering tremendous casualties. Following the end of the war, the UN Security Council passed Resolution 338 confirming the land-for-peace principle established in Resolution 242, initiating the Middle East peace process. The Arab defeat would play an important role in the PLO's willingness to pursue a negotiated settlement to the conflict, while many Israelis began to believe that the area under Israeli occupation could not be held indefinitely by force. The Camp David Accords, agreed upon by Israel and Egypt in 1978, primarily aimed to establish a peace treaty between the two countries. The accords also proposed the creation of a "Self-Governing Authority" for the Arab population in the West Bank and Gaza Strip, excluding Jerusalem, under Israeli control. A peace treaty based on these accords was signed in 1979, leading to Israel's withdrawal from the occupied Egyptian Sinai Peninsula by 1982.
1982 Lebanon War During the
Lebanese Civil War, Palestinian militants continued to launch attacks against Israel while also battling opponents within Lebanon. In 1978, the
Coastal Road massacre led to the Israeli full-scale invasion known as
Operation Litani. This operation sought to dislodge the from Lebanon while expanding the area under the control of the Israeli allied Christian militias in southern Lebanon. The operation succeeded in leaving a large portion of the south in control of the Israeli proxy which would eventually form the
South Lebanon Army. Under United States pressure, Israeli forces would eventually withdraw from Lebanon. In 1982, Israel, having secured its southern border with Egypt, sought to resolve the Palestinian issue by attempting to dismantle the military and political power of the PLO in Lebanon. The goal was to establish a friendly regime in Lebanon and continue its policy of settlement and annexation in occupied Palestine. The PLO had observed the latest ceasefire with Israel and shown a preference for negotiations over military operations. As a result, Israel sought to remove the PLO as a potential negotiating partner. Most Palestinian militants were defeated within several weeks, Beirut was captured, and the PLO headquarters were evacuated to Tunisia in June by Yasser Arafat's decision.
First Intifada (1987–1993) For causes that are not agreed on beyond political frustration, the first Palestinian uprising began in 1987. Palestinian historian Rashid Khalidi compares it to the 1936-1939 Arab Revolt. He views it as a grassroots popular protest that started in response to a collision involving an Israeli army vehicle and also as a result of the suppression of the Palestinian national movement. He points to the large involvement of youth and women taking leadership roles in normally male dominated politics, to illustrate its popularity. American political scientist Mary King believes it was a response to Israel's military occupation, escalating attacks on Palestinians, and policies of settlement building and collective punishment and that uprising largely consisted of nonviolent acts of civil disobedience and protest. Israeli historian Benny Morris points to the death of an Arab schoolgirl and the wounding of two others by stay bullets in the preceding weeks as well as a rising numbers of clashes in the preceding years. He views the Intifada as largely unarmed rather than nonviolent, noting the use of knives and other improvised weapons, as well as the hundreds of casualties in the first month. By the early 1990s, the conflict, termed the
First Intifada, was the focus of international settlement efforts, in part motivated by the success of the Egyptian–Israeli peace treaty of 1982. Eventually the
Israeli–Palestinian peace process led to the
Oslo Accords of 1993, allowing the PLO to relocate from Tunisia and take ground in the
West Bank and
Gaza Strip, establishing the
Palestinian National Authority. The peace process also had significant opposition among elements of Palestinian society, such as Hamas and Palestinian Islamic Jihad, who immediately initiated a campaign of attacks targeting Israelis. Following hundreds of casualties and a wave of anti-government propaganda, Israeli Prime Minister
Rabin was assassinated by an
Israeli far-right extremist who objected to the peace initiative. This struck a serious blow to the peace process, which in 1996 led to the newly elected government of Israel backing off from the process, to some degree. However, the
United Nations,
Human Rights Watch and many other international bodies and
NGOs continue to consider Israel to be the occupying power of the Gaza Strip as Israel controls Gaza Strip's airspace, territorial waters and controls the movement of people or goods in or out of Gaza by air or sea.
Fatah–Hamas split (2006–2007) In 2006, Hamas won a plurality of 44% in the
Palestinian parliamentary election. Israel responded it would begin
economic sanctions unless Hamas agreed to accept prior Israeli–Palestinian agreements, forswear violence, and recognize Israel's right to exist, all of which Hamas rejected. After internal Palestinian political struggle between Fatah and Hamas erupted into the
2007 Battle of Gaza, Hamas took full control of the area. In 2007, Israel imposed a naval
blockade on the Gaza Strip, and cooperation with Egypt allowed a ground blockade of the Egyptian border. The tensions between Israel and Hamas escalated until late 2008, when Israel launched operation
Cast Lead upon Gaza, resulting in thousands of civilian casualties and billions of dollars in damage. By February 2009, a ceasefire was signed with international mediation between the parties, though the occupation and small and sporadic eruptions of violence continued. In 2011, a Palestinian Authority attempt to gain UN membership as a fully sovereign state failed. In Hamas-controlled Gaza, sporadic rocket attacks on Israel and Israeli air raids continued to occur. In November 2012, Palestinian representation in the UN was upgraded to a non-member observer state, and its mission title was changed from "Palestine (represented by PLO)" to "
State of Palestine". In 2014,
another war broke out between Israel and Gaza, resulting in over 70 Israeli and over 2,000 Palestinian casualties.
2023–present Gaza war in Gaza and southern Israel After the 2014 war and
2021 crisis, Hamas began planning an attack on Israel. In 2022, Netanyahu returned to power while headlining a hardline
far-right government, which led to greater political strife in Israel and clashes in the Palestinian territories. This culminated in
a surprise attack launched by Hamas-led militant groups on southern Israel from the Gaza Strip on 7 October 2023, in which more than 1,195 Israeli civilians, military personnel, and other foreign nationals were killed, and
251 were taken hostage into Gaza. The Israeli military responded by
declaring war on Hamas and conducting an extensive
aerial bombardment campaign on Gaza, followed by a
large-scale ground invasion with the stated goal of destroying Hamas, freeing hostages, and controlling security in Gaza afterwards. South Africa
accused Israel of
genocide at the
International Court of Justice and called for an immediate ceasefire. The court issued an order requiring Israel to take all measures to prevent any acts contrary to the
1948 Genocide Convention, but did not order Israel to suspend its military campaign. The war
spilled over the Middle East, with Israel engaging in clashes with local militias
in the West Bank,
Hezbollah in Lebanon and northern Israel, and other Iranian-backed militias in Syria, as well as
Iran itself. Iranian-backed militias also engaged in
clashes with the United States, while the
Houthis blockaded the Red Sea in protest, to which the United States responded with airstrikes in
Yemen,
Iraq, and Syria. Taking advantage of the weakening position of Iranian-backed militias,
Syrian opposition groups initiated
an offensive in November 2024 that reignited the
Syrian civil war, culminating in the
fall of the Assad regime and the establishment of
a transitional government in the place of
the former Ba'athist government; Israel
invaded the area around
its demarcated boundaries with Syria shortly afterwards. in January 2025 The war has caused widespread destruction, a
humanitarian crisis, and an
ongoing famine in the Gaza Strip, though some dispute this. Over 60,000 Palestinians in Gaza
have been killed, almost half of them
women and
children, and more than 148,000 have been injured. A study in
The Lancet estimated 64,260 deaths in Gaza from
traumatic injuries by June 2024, while noting a potentially larger death toll when "indirect" deaths are included. As of May 2025, a comparable figure for traumatic injury deaths would be 93,000.
September 2025 developments On 9 September 2025, Israeli airstrikes targeted senior Hamas leaders in
Doha. Reports differed: some sources stated that senior leaders survived, while others reported deaths of lower-level operatives and at least one Qatari officer. On 12 September, the
United Nations General Assembly adopted the
New York Declaration by a vote of 142 in favour, 10 opposed and 12 abstentions. The declaration endorses concrete steps toward a
two-state solution and calls for measures to establish a Palestinian government free of Hamas's control as part of a broader political process.
Current Status As of April 2026
, a ceasefire has largely been in effect since 10 October 2025. The last remaining living
Gaza war hostages were returned in October 2025, and last body was recovered by January 2026. == Attempts to reach a peaceful settlement ==
