Founding The Irgun's first steps were in the aftermath of the
Riots of 1929. In the
Jerusalem branch of the Haganah there were feelings of disappointment and internal unrest towards the leadership of the movements and the
Histadrut (at that time the organization running the Haganah). These feelings were a result of the view that the Haganah was not adequately defending Jewish interests in the region. Likewise, critics of the leadership spoke out against alleged failures in the number of weapons, readiness of the movement and its policy of restraint and not fighting back. On April 10, 1931, commanders and equipment managers announced that they refused to return weapons to the Haganah that had been issued to them earlier, prior to the
Nebi Musa holiday. These weapons were later returned by the commander of the Jerusalem branch,
Avraham Tehomi, a.k.a. "Gideon". However, the commanders who decided to rebel against the leadership of the Haganah relayed a message regarding their resignations to the
Vaad Leumi, and thus this schism created a new independent movement. The leader of the new underground movement was
Avraham Tehomi, alongside other founding members who were all senior commanders in the Haganah, members of
Hapoel Hatzair and of the Histadrut. Also among them was
Eliyahu Ben Horin, an activist in the
Revisionist Party. This group was known as the "Odessan Gang", because they previously had been members of the ''Haganah Ha'Atzmit
of Jewish Odessa. The new movement was named Irgun Tsvai Leumi'', ("National Military Organization") in order to emphasize its active nature in contrast to the Haganah. Moreover, the organization was founded with the desire to become a true military organization and not just a
militia as the Haganah was at the time. In the autumn of that year the Jerusalem group merged with other armed groups affiliated with
Betar. The Betar groups' center of activity was in
Tel Aviv, and they began their activity in 1928 with the establishment of "Officers and Instructors School of Betar". Students at this institution had broken away from the Haganah earlier, for political reasons, and the new group called itself the "National Defense", הגנה הלאומית. During the riots of 1929 Betar youth participated in the defense of Tel Aviv neighborhoods under the command of Yermiyahu Halperin, at the behest of the Tel Aviv city hall. After the riots the Tel Avivian group expanded, and was known as "The
Right Wing Organization". After the Tel Aviv expansion another branch was established in
Haifa. Towards the end of 1932 the Haganah branch of
Safed also defected and joined the Irgun, as well as many members of the
Maccabi sports association. At that time the movement's underground newsletter, ''Ha'Metsudah'' (the Fortress) also began publication, expressing the active trend of the movement. The Irgun also increased its numbers by expanding draft regiments of Betar – groups of volunteers, committed to two years of security and pioneer activities. These regiments were based in places that from which stemmed new Irgun strongholds in the many places, including the settlements of
Yesod HaMa'ala,
Mishmar HaYarden,
Rosh Pina,
Metula and
Nahariya in the north; in the center –
Hadera,
Binyamina,
Herzliya,
Netanya and
Kfar Saba, and south of there –
Rishon LeZion,
Rehovot and
Ness Ziona. Later on regiments were also active in the
Old City of Jerusalem ("the Kotel Brigades") among others. Primary training centers were based in
Ramat Gan,
Qastina (by
Kiryat Mal'akhi of today) and other places.
Under Tehomi's command , the first Commander of the Irgun In 1933 there were some signs of unrest, seen by the incitement of the local Arab leadership to act against the authorities. The strong British response put down the disturbances quickly. During that time the Irgun operated in a similar manner to the Haganah and was a guarding organization. The two organizations cooperated in ways such as coordination of posts and even intelligence sharing. Within the Irgun, Tehomi was the first to serve as "Head of the Headquarters" or "Chief Commander". Alongside Tehomi served the senior commanders, or "Headquarters" of the movement. As the organization grew, it was divided into district commands. In August 1933 a "Supervisory Committee" for the Irgun was established, which included representatives from most of the Zionist political parties. The members of this committee were
Meir Grossman (of the Hebrew State Party), Rabbi
Meir Bar-Ilan (of the
Mizrachi Party), either
Immanuel Neumann or
Yehoshua Supersky (of the
General Zionists) and
Ze'ev Jabotinsky or
Eliyahu Ben Horin (of
Hatzohar). In protest against, and with the aim of ending
Jewish immigration to Palestine, the
Great Arab Revolt of 1936–1939 broke out on April 19, 1936. The riots took the form of attacks by Arab rioters ambushing main roads, bombing of roads and settlements as well as property and agriculture vandalism. In the beginning, the Irgun and the Haganah generally maintained a policy of restraint, apart from a few instances. Some expressed resentment at this policy, leading up internal unrest in the two organizations. The Irgun tended to retaliate more often, and sometimes Irgun members patrolled areas beyond their positions in order to encounter attackers ahead of time. However, there were differences of opinion regarding what to do in the Haganah, as well. Due to the joining of many
Betar Youth members, Jabotinsky (founder of Betar) had a great deal of influence over Irgun policy. Nevertheless, Jabotinsky was of the opinion that for moral reasons violent retaliation was not to be undertaken. In November 1936 the
Peel Commission was sent to inquire regarding the breakout of the riots and propose a solution to end the Revolt. In early 1937 there were still some in the
Yishuv who felt the commission would recommend a partition of
Mandatory Palestine (the land west of the
Jordan River), thus creating a Jewish state on part of the land. The Irgun leadership, as well as the "Supervisory Committee" held similar beliefs, as did some members of the Haganah and the
Jewish Agency. This belief strengthened the policy of
restraint and led to the position that there was no room for defense institutions in the future Jewish state. Tehomi was quoted as saying: "We stand before great events: a Jewish state and a Jewish army. There is a need for a single military force". This position intensified the differences of opinion regarding the policy of restraint, both within the Irgun and within the political camp aligned with the organization. The leadership committee of the Irgun supported a merger with the Haganah. On April 24, 1937, a referendum was held among Irgun members regarding its continued independent existence. David Raziel and Avraham (Yair) Stern came out publicly in support for the continued existence of the Irgun: The Irgun has been placed ... before a decision to make, whether to submit to the authority of the government and the
Jewish Agency or to prepare for a double sacrifice and endangerment. Some of our friends do not have appropriate willingness for this difficult position, and have submitted to the Jewish Agency and has left the battle ... all of the attempts ... to unite with the leftist organization have failed, because the Left entered into negotiations not on the basis of unification of forces, but the submission of one such force to the other....
The first split In April 1937 the Irgun split after the referendum. Approximately 1,500–2,000 people, about half of the Irgun's membership, including the senior command staff, regional committee members, along with most of the Irgun's weapons, returned to the Haganah, which at that time was under the Jewish Agency's leadership. The Supervisory Committee's control over the Irgun ended, and Jabotinsky assumed command. In their opinion, the removal of the Haganah from the Jewish Agency's leadership to the national institutions necessitated their return. Furthermore, they no longer saw significant ideological differences between the movements. Those who remained in the Irgun were primarily young activists, mostly laypeople, who sided with the independent existence of the Irgun. In fact, most of those who remained were originally Betar people.
Moshe Rosenberg estimated that approximately 1,800 members remained. In theory, the Irgun remained an organization not aligned with a political party, but in reality the supervisory committee was disbanded and the Irgun's continued ideological path was outlined according to Ze'ev Jabotinsky's school of thought and his decisions, until the movement eventually became Revisionist Zionism's military arm. One of the major changes in policy by Jabotinsky was the end of the policy of
restraint. On April 27, 1937, the Irgun founded a new headquarters, staffed by Moshe Rosenberg at the head,
Avraham (Yair) Stern as secretary,
David Raziel as head of the Jerusalem branch,
Hanoch Kalai as commander of Haifa and
Aharon Haichman as commander of Tel Aviv. On 20
Tammuz, (June 29) the day of
Theodor Herzl's death, a ceremony was held in honor of the reorganization of the underground movement. For security purposes this ceremony was held at a construction site in Tel Aviv. Ze'ev Jabotinsky placed Col.
Robert Bitker at the head of the Irgun. Bitker had previously served as Betar commissioner in China and had military experience. A few months later, probably due to total incompatibility with the position, Jabotinsky replaced Bitker with Moshe Rosenberg. When the
Peel Commission report was published a few months later, the Revisionist camp decided not to accept the commission's recommendations. Not all of the aforementioned operations received a commander's approval, and Jabotinsky was not in favor of such actions at the time. Jabotinsky still hoped to establish a Jewish force out in the open that would not have to operate underground. However, the failure, in its eyes, of the
Peel Commission and the renewal of violence on the part of the Arabs caused the Irgun to rethink its official policy.
Increase in operations 14 November 1937 was a watershed in Irgun activity. From that date, the Irgun increased its reprisals. Following an increase in the number of attacks aimed at Jews, including the killing of five
kibbutz members near
Kiryat Anavim (today kibbutz
Ma'ale HaHamisha), the Irgun undertook a series of attacks in various places in Jerusalem, killing five Arabs. Operations were also undertaken in
Haifa (shooting at the Arab-populated
Wadi Nisnas neighborhood) and in
Herzliya. The date is known as the day the policy of restraint (
Havlagah) ended, or as
Black Sunday when operations resulted in the murder of 10 Arabs. This is when the organization fully changed its policy, with the approval of Jabotinsky and Headquarters to the policy of "active defense" in respect of Irgun actions. The British responded with the arrest of Betar and Hatzohar members as suspected members of the Irgun.
Military courts were allowed to act under "Time of Emergency Regulations" and even sentence people to death. In this manner
Yehezkel Altman, a guard in a Betar battalion in the
Nahalat Yizchak neighborhood of Tel Aviv, shot at an Arab bus, without his commanders' knowledge. Altman was acting in response to a shooting at Jewish vehicles on the Tel Aviv–Jerusalem road the day before. He turned himself in later and was sentenced to death, a sentence which was later commuted to a life sentence. Despite the arrests, Irgun members continued fighting. Jabotinsky lent his moral support to these activities. In a letter to Moshe Rosenberg on 18 March 1938 he wrote: Tell them: from afar I collect and save, as precious treasures, news items about your lives. I know of the obstacles that have not impeded your spirit; and I know of your actions as well. I am overjoyed that I have been blessed with such students. Although the Irgun continued activities such as these, following Rosenberg's orders, they were greatly curtailed. Furthermore, in fear of the British threat of the death sentence for anyone found carrying a weapon, all operations were suspended for eight months. However, opposition to this policy gradually increased. In April, 1938, responding to the killing of six Jews, Betar members from the
Rosh Pina Brigade went on a reprisal mission, without the consent of their commander, as described by historian
Avi Shlaim: On 21 April 1938, after several weeks of planning, he and two of his colleagues from the Irgun (Etzel) ambushed an Arab bus at a bend on a mountain road near Safad. They had a hand grenade, a gun and a pistol. Their plan was to destroy the engine so that the bus would fall off the side of the road and all the passengers would be killed. When the bus approached, they fired at it (not in the air, as Mailer has it) but the grenade lobbed by Ben Yosef did not detonate. The bus with its screaming and terrified passengers drove on. The transfer of handguns, rifles, explosives and ammunition stopped with the outbreak of World War II. Another field in which the Irgun operated was the training of pilots, so they could serve in the
Air Force in the future war for independence, in the flight school in
Lod. Towards the end of 1938 there was progress towards aligning the ideologies of the Irgun and the Haganah. Many abandoned the belief that the land would be divided and a Jewish state would soon exist. The Haganah founded פו"מ, a special operations unit, (pronounced
poom), which carried out reprisal attacks following Arab violence. These operations continued into 1939. Furthermore, the opposition within the
Yishuv to illegal immigration significantly decreased, and the Haganah began to bring Jews to Palestine using rented ships, as the Irgun had in the past.
First operations against the British The publishing of the MacDonald
White Paper of 1939 brought with it new edicts that were intended to lead to a more equitable settlement between Jews and Arabs. However, it was considered by some Jews to have an adverse effect on the continued development of the Jewish community in Palestine. Chief among these was the prohibition on selling land to Jews, and the smaller quotas for Jewish immigration. The entire Yishuv was furious at the contents of the White Paper. There were demonstrations against the "Treacherous Paper", as it was considered that it would preclude the establishment of a Jewish homeland in Palestine. Under the temporary command of
Hanoch Kalai, the Irgun began sabotaging strategic infrastructure such as electricity facilities, radio and telephone lines. It also started publicizing its activity and its goals. This was done in street announcements, newspapers, as well as the underground radio station
Kol Zion HaLochemet. On August 26, 1939, the Irgun killed
Ralph Cairns, a British police officer who, as head of the Jewish Department in the
Palestine Police, had been closing the net on
Avraham Stern. Irgun had accused him of the
torture of a number of its members. Cairns and Ronald Barker, another British police officer, were killed by a remotely detonated Irgun
landmine. The British increased their efforts against the Irgun. As a result, on August 31 the British police arrested members meeting in the Irgun headquarters. On the next day, September 1, 1939, World War II broke out. ==During World War II==
