After a much-disputed truce on 3 January 1928, the Italian policy in Libya reached the level of full-scale war, including deportation and concentration of people of northern Cyrenaica to deny the rebels the support of the local population. After Omar Mukhtar's capture September 15, 1931 and his execution in Benghazi, the resistance gradually disappeared. Limited resistance to the Italian occupation crystallized round Sheik Idris, the Sennusi Emir of Cyrenaica.
