"The National Military Organization in the Land of Israel") was a Zionist paramilitary organization that operated in Mandate Palestine between 19.
It was an offshoot of the older and larger Jewish paramilitary organization Haganah (Hebrew: ), an acronym of the Hebrew initials, or by the abbreviation IZL.
The Irgun policy was based on what was then called Revisionist Zionism founded by Ze'ev Jabotinsky.
According to Howard Sachar, "The policy of the new organization was based squarely on Jabotinsky's teachings: every Jew had the right to enter Palestine; only active retaliation would deter the Arabs; only Jewish armed force would ensure the Jewish state".
Two of the operations for which the Irgun is best known are the bombing of the King David Hotel in Jerusalem on 22 July 1946 and the Deir Yassin massacre, carried out together with Lehi on 9 April 1948.
The Irgun has been viewed as a terrorist organization or organization which carried out terrorist acts.
Specifically the organization "committed acts of terrorism and assassination against the British, whom it regarded as illegal occupiers, and it was also violently anti-Arab" according to the Encyclopædia Britannica.
Members of the Irgun came mostly from Betar and from the Revisionist Party both in Palestine and abroad.
The Revisionist Movement made up a popular backing for the underground organization.
Ze'ev Jabotinsky, founder of Revisionist Zionism, commanded the organization until he died in 1940.
