Cause

The United Nations voted on 29 November 1947 to adopt the Partition Plan for Palestine, dividing the territory into separate Jewish and Arab states. This decision sparked immediate intercommunal violence between Arab and Jewish communities in British Mandatory Palestine, with Arab states opposing partition and Zionist leadership accepting it, setting the stage for armed conflict.

Event

The war unfolded in two phases: a civil war beginning 30 November 1947, and an international war from 14 May 1948 when Israel declared statehood and neighbouring Arab armies invaded. Israeli forces, after early defensive fighting, enacted Plan Dalet, halted the Arab advance, and pushed back Egyptian, Jordanian, Iraqi, Syrian, and Lebanese forces, capturing approximately 78% of Mandatory Palestine.

Consequence

The war ended with the 1949 Armistice Agreements, establishing the Green Line as Israel's de facto borders and leaving Jordan in control of the West Bank and Egypt controlling Gaza. Over 700,000 Palestinians were expelled or fled — an event Palestinians call the Nakba — founding the Palestinian refugee problem. Hundreds of thousands of Jews subsequently fled or were expelled from Arab states.
