The Irgun (Hebrew: ארגון‎; full title: הארגון הצבאי הלאומי בארץ ישראל‎ Hā-ʾIrgun Ha-Tzvaʾī Ha-Leūmī b-Ērētz Yiśrāʾel, lit. "The National Military Organization in the Land of Israel") was a Zionist paramilitary organization that operated in Mandate Palestine between 1931 and 1948. It was an offshoot of the older and larger Jewish paramilitary organization Haganah (Hebrew: הגנה‎, Defence). When the group broke from the Haganah it became known as the Haganah Bet (Hebrew: literally "Defense 'B' " or "Second Defense", הגנה ב‎), or alternatively as haHaganah haLeumit (ההגנה הלאומית) or Hama'amad (המעמד‎). Irgun members were absorbed into the Israel Defense Forces at the start of the 1948 Arab–Israeli war. The Irgun is also referred to as Etzel (אצ"ל‎), an acronym of the Hebrew initials, or by the abbreviation IZL.
