1948 Arab–Israeli War
The 1948 Arab–Israeli War, also called the First Arab–Israeli War, lasted from 15 May 1948 to 10 March 1949. It was the second stage of the 1948 Palestine war, following a civil war that began on 29 November 1947. That civil war started after the United Nations General Assembly voted to partition Mandatory Palestine into an Arab state (about 43% of the territory) and a Jewish state (about 56%), with Jerusalem and Bethlehem as an international zone. Jewish leaders accepted the plan; Palestinian Arab leaders and the broader Arab world rejected it. The next day, Palestinian militias and mobs attacked Jewish areas, and the conflict escalated as the British Mandate authorities withdrew.
In April 1948, Zionist forces launched Plan Dalet, an offensive that conquered and depopulated cities, villages, and territories in preparation for a Jewish state. On 14 May 1948, Zionist leaders declared the independence of Israel, ending the British Mandate at midnight. The following morning, Egypt, Transjordan, Syria, and expeditionary forces from Iraq invaded, taking control of Arab areas and attacking Israeli forces and settlements. Fighting occurred mostly within the former Mandate territory, as well as in the Sinai Peninsula and southern Lebanon, interrupted by several truces.
By the war’s end, Israel controlled about 78% of former Mandatory Palestine. This included all the area proposed for a Jewish state, nearly 60% of the area proposed for an Arab state (including Jaffa, Lydda, Ramla, Upper Galilee, parts of the Negev, the west coast near Gaza City, and a strip along the Tel Aviv–Jerusalem road), and West Jerusalem, which was meant to be part of the international zone. Transjordan took East Jerusalem and the West Bank, annexing it the following year. Egypt occupied the Gaza Strip.
Expulsions of Palestinians, which began during the civil war, continued. Hundreds were killed in multiple massacres, such as those during the expulsions from Lydda and Ramla. These events are known as the Nakba, or “the catastrophe,” and mark the start of the Palestinian refugee problem. In the three years after the war, a similar number of Jews fled or were expelled from Arab states, with 260,000 going to Israel. The war formally ended with the 1949 Armistice Agreements, which established the Green Line.
Lore & Background
The 1948 Arab–Israeli War, the second and final stage of the 1948 Palestine war, followed months of civil war that erupted after the United Nations proposed partitioning the British Mandate into separate Arab and Jewish states. Jewish leaders accepted the plan; Arab leaders and the broader Arab world rejected it. The conflict escalated dramatically when Zionist forces launched a major offensive, conquering and depopulating cities and villages across the mandate. Immediately after the British Mandate expired and Israel declared independence, military coalitions from Egypt, Transjordan, Syria, and Iraq invaded, seizing Arab areas and attacking Israeli settlements. Fighting occurred mostly within the former mandate territory, as well as in the Sinai Peninsula and southern Lebanon, punctuated by truce periods. By the war’s end, Israel controlled roughly 78% of the mandate, including all territory proposed for a Jewish state and nearly 60% of the proposed Arab state, plus West Jerusalem. Transjordan took East Jerusalem and the West Bank, annexing them later; Egypt occupied the Gaza Strip. The war saw the systematic expulsion of Palestinians, including massacres in Lydda and Ramla, events remembered as the Nakba, which created the Palestinian refugee crisis. In the following years, a comparable number of Jews fled or were expelled from Arab states, with many resettling in Israel.
Reader's Guide
By the war’s end, Israel controlled about 78% of the former Mandatory Palestine, encompassing all territory the UN had proposed for a Jewish state, nearly 60% of the area proposed for an Arab state (including Jaffa, Lydda, Ramla, Upper Galilee, parts of the Negev, the west coast near Gaza City, and a strip along the Tel Aviv–Jerusalem road), and West Jerusalem—which was meant to be an international zone. Transjordan took East Jerusalem and the West Bank, annexing them the following year; Egypt occupied the Gaza Strip. The conflict’s ecology was shaped by the terrain of the British Mandate, the Sinai Peninsula, and southern Lebanon, with fighting interrupted by several truces. Behaviorally, the war followed the civil war that began after the UN partition vote, escalating when Zionist forces launched Plan Dalet in April 1948, conquering and depopulating cities and villages to prepare for a Jewish state. The next day after Israel’s declaration of independence, Egypt, Transjordan, Syria, and Iraqi expeditionary forces invaded, attacking Israeli forces and settlements. Expulsions of Palestinians, which started during the civil war, continued, with hundreds killed in massacres such as those at Lydda and Ramla. These events, known as the Nakba, initiated the Palestinian refugee problem; simultaneously, a similar number of Jews fled or were expelled from Arab states in the three years after the war, with 260,000 going to Israel. The war’s significance lies in establishing the Green Line borders via the 1949 Armistice Agreements, creating lasting territorial divisions and hostilities that define the region’s geopolitics. It relates to its field as the foundational conflict of the Arab–Israeli dispute, shaping modern Middle Eastern history, refugee studies, and international law regarding occupation and partition.

Frequently Asked Questions
Who were the main combatants in the 1948 Arab–Israeli War?
On one side stood the newly declared State of Israel, and on the other a military coalition of neighboring Arab states that crossed into the former British Mandate territory. The conflict was therefore a regional, multi-state war rather than a single bilateral confrontation.
Why is the 1948 Arab–Israeli War important to Cold War history?
It was the first major armed clash in the Middle East during the early Cold War, immediately drawing in outside powers and setting the stage for decades of regional tension. The resulting borders and mass-displacement situation shaped every subsequent conflict in the region through the rest of the twentieth century.
