Jewish insurgency in Mandatory Palestine
From 1944 until 1948, Zionist militias and underground groups—including Haganah, Lehi, and Irgun—carried out a paramilitary campaign against British rule in Mandatory Palestine. 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.
