After the British Withdrawal from Palestine: May 1948

On May 14, 1948, as the last British High Commissioner departed Haifa, the Jewish People's Council (led by David Ben-Gurion) declared the establishment of the State of Israel in Tel Aviv. The following day, May 15, armies from five Arab states—Egypt, Transjordan, Syria, Lebanon, and Iraq—crossed into the former Mandate territory, initiating the 1948 Arab–Israeli War (known in Israel as the War of Independence, in Arabic as the Nakba).

Immediate Sequence

1. Midnight May 14/15: British Mandate legally terminates.
2. Afternoon May 14: Declaration of Independence ceremony at Tel Aviv Museum.
3. May 15, dawn: Egyptian forces advance from south; Jordanian Arab Legion enters West Bank; Syrian/Lebanese forces attack north; Iraqi expeditionary force moves toward central Palestine.
4. May 15 onward: Fighting erupts on multiple fronts; Jerusalem besieged; Palestinian displacement accelerates.

Context

The UN Partition Plan (Resolution 181, Nov 1947) proposed separate Jewish and Arab states. Jewish leadership accepted; Arab leadership rejected. British withdrawal triggered the power vacuum both sides sought to fill.

Outcome

The war lasted until 1949 armistices. Israel expanded beyond partition borders; Jordan annexed West Bank/East Jerusalem; Egypt held Gaza. ~700,000 Palestinians became refugees. No Palestinian state emerged.

This sequence—declaration, invasion, war—defined the modern Middle East conflict.
