A successful paramilitary campaign, sometimes referred to as the Palestine Emergency, was carried out by Zionist underground groups against British rule in Mandatory Palestine from 1944 to 1948. The tensions between the Zionist underground and the British mandatory authorities rose from 1938 and intensified with the publication of the White Paper of 1939. The Paper outlined new government policies to place further restrictions on Jewish immigration and land purchases, and declared the intention of giving independence to Palestine, with an Arab majority, within ten years. Though World War II brought relative calm, tensions again escalated into an armed struggle towards the end of the war, when it became clear that the Axis powers were close to defeat.

Mandatory Palestine was a geopolitical entity that existed between 1920 and 1948 in the region of Palestine under the terms of the League of Nations Mandate for Palestine.
