Arab–Israeli War: The port city of Haifa is captured by Jewish forces.

The 1948 Arab–Israeli War, also known as the First Arab–Israeli War, followed the civil war in Mandatory Palestine as the second and final stage of the 1948 Palestine war. The civil war became a war of separate states with the Israeli Declaration of Independence on 14 May 1948, the end of the British Mandate for Palestine at midnight, and the entry of a military coalition of Arab states into the territory of Mandatory Palestine the following morning. The war formally ended with the 1949 Armistice Agreements which established the Green Line.

Haifa is the third-largest city in Israel—after Jerusalem and Tel Aviv—with a population of 290,306 in 2022. The city of Haifa forms part of the Haifa metropolitan area, the third-most populous metropolitan area in Israel. It is home to the Baháʼí Faith's Baháʼí World Centre, and is a UNESCO World Heritage Site and a destination for Baháʼí pilgrimage.

The Battle of Haifa, also known as the Fall of Haifa, and called by the Jewish forces Operation Bi'ur Hametz, was a Haganah operation carried out on 21–22 April 1948 and a major event in the final stages of the civil war in Palestine, leading up to the 1948 Arab-Israeli War. The objective of the operation was the capture of the Arab neighborhoods of Haifa. The operation formed part of the 1948 Palestinian expulsion and flight, with approximately 15,000 Arab residents being displaced between April 21–22, and with only 4,000 remaining in the city by mid-May from a pre-conflict population of approximately 65,000.
