01In brief
Brit HaBirionim was a Revisionist Zionist underground group active in Mandatory Palestine from 1930 to 1933 against British rule, founded and led ideologically by Abba Ahimeir. With about 30 active members and a few score of sympathizers, it organized anti-Mandate demonstrations, shofar blowing at the Western Wall, and the removal of swastika flags from German consulates in Jerusalem and Jaffa. Its leading figures included Uri Zvi Greenberg and Yehoshua Yeivin, and its principal newspaper was Hazit Ha'am. The group disintegrated following the murder of Chaim Arlosoroff and action against it by the Mandatory authorities; the murder accusation against Ahimeir was dropped, while separate proceedings led to his imprisonment for sedition.
02Overview
Brit HaBirionim combined a small underground organization with public protest and newspaper agitation against the British Mandatory government.[1] Its members called the Mandatory authorities a “foreign occupier” and campaigned against their rule.[3] Although it had only about 30 active members and a few score of sympathizers, the group dominated the Revisionist party organ in Palestine, Hazit Ha'am.[1]
Its opposition also extended to Mapai and the leadership of the Yishuv, against whom its newspaper conducted a vocal campaign.[4] Ahimeir and the group shared the Revisionist objective of “a Hebrew state on both sides of the Jordan.”[2] Its activities were limited in scope, and its demonstrations were nonviolent despite its incendiary political language.[1][2]
03Origins and History
Abba Ahimeir joined the Revisionist movement in 1928 and advocated active opposition to the Mandatory government.[5] Brit HaBirionim emerged in 1930 as the formalization of a network created by his Bet Sefer cadets.[1][2] Alongside Ahimeir, the poet Uri Zvi Greenberg and the writer Yehoshua Yeivin were leading figures in the organization.[3]
The group's name drew on the ancient biryonim, associated with the Zealots of the Second Temple period.[2] In a retrospective opinion article, Yossi Ahimeir credits Greenberg with naming the organization and interprets its reference to ancient Jewish “brigands” as invoking fighters against Roman rule rather than criminals.[6] He portrays its activists as young nationalists responding to the calls of Ahimeir, Greenberg, and Yeivin.[6]
The group's newspaper, Hazit Ha'am—“People's Front”—was established in 1931 after Jabotinsky lost control of Do'ar Ha-Yom.[7] It followed the closure of Ha'am by several months.[4] The surviving online archive of Ha'am, published in Jerusalem, covers March 24 through August 7, 1931; those archive dates do not by themselves establish its precise closure date.[8]
Ahimeir edited Hazit Ha'am, while Dr. Hareven served as its “editor in charge” under Jabotinsky's supervision.[7] Published in Hebrew in Tel Aviv, it appeared weekly or biweekly.[4][7] Its digitized holdings encompass 189 issues and 786 pages, dated January 29, 1932, through June 12, 1934.[4] Eliahu Ben-Horin succeeded Jabotinsky as editor-in-chief in 1934, and the publication was subsequently renamed Ha-Yarden, then Ha-Mashkif and Ha-Yom.[7]
Brit HaBirionim disintegrated shortly after Arlosoroff's murder in June 1933, amid persecution by the Mandatory authorities.[1][2] Ahimeir was arrested, and police seized Revisionist archives and some of his writings.[2] The murder indictment against him was formally dropped on May 16, 1934; separate sedition proceedings followed on July 12, 1934.[2] He received a twenty-one-month prison sentence, later reduced to eighteen months, and was released in August 1935.[9]
04Protest and Public Activity
In October 1930, Brit HaBirionim demonstrated against the visit of Drummond Shiels, the British under-secretary of state for the colonies, whom it associated with the Passfield White Paper.[2] Ahimeir and two others were arrested.[2] In his retrospective account, Yossi Ahimeir dates this first demonstration to October 9 in Tel Aviv and says that the protest and subsequent trial received prominent newspaper coverage.[6] He presents the nonviolent action as an effort to change Jewish public opinion and encourage young people to pursue national liberation.[6]
The group opposed the official census in 1931 and called for a boycott.[1][2] It feared that the census could lead to the establishment of a representative legislative assembly with an Arab majority.[2] Ahimeir was arrested repeatedly from 1930 onward for organizing illegal public action.[5]
In February 1932, members disrupted a Hebrew University ceremony installing Norman Bentwich as professor of peace studies.[2] Ahimeir and his followers opposed Bentwich's dovish views and his association with Judah Magnes and Brit Shalom.[2] University security called the police, Ahimeir was arrested, and fifteen students were suspended following the disruption.[2]
Brit HaBirionim also organized the sounding of the shofar at the Western Wall at the conclusion of the Yom Kippur service.[1] Under British rule, blowing a shofar or bringing a Torah scroll to the Wall was illegal, and those who did so risked arrest.[10] Young people secretly brought shofars to the Wall and sounded them at the end of the fast.[10]
After Nazi Germany instituted its April 1, 1933 boycott of Jewish businesses, the group attacked the German consulates in Jerusalem and Jaffa and removed their Nazi flags.[2] The German imperial flag was left in place.[2] Before this action, the group had treated Hitler as another persecutor of Jews; the state-sponsored exclusion of Jews in Germany shocked its members.[2]
05Significance
Brit HaBirionim's short history brought together opposition to British rule, resistance to restrictions on Jewish religious practice at the Western Wall, and direct action against Nazi symbols.[1] Its public demonstrations remained limited in scale, but its control of Hazit Ha'am gave it a platform within Revisionist political life beyond its small active membership.[1]
The newspaper opposed not only the Mandatory government but also Mapai and the Yishuv's leaders.[4] Its surviving run preserves the group's political journalism alongside its better-known demonstrations, census boycott campaign, and consular flag removals.[1][4]
06Controversies
The group occupied the extreme right of Revisionism, and its leaders challenged both the Labor movement and positions taken by Jabotinsky and the Revisionist party.[1][9] Ahimeir sought a revolutionary Zionism and declared, “Our teacher is not Herzl or Jabotinsky, but Lenin,” admiring Lenin's practical path rather than embracing Leninist doctrine, the Soviet Union, or international Communism.[2] Some leaders and supporters expressed support for Italian Fascism and approval of Hitler's mass following and actions against the German left; these politically charged statements should not be generalized into a uniform position held by every member.[9]
Brit HaBirionim strongly opposed the Transfer Agreement, regarding it as a surrender of Jewish national honor for money, while supporters considered it a practical means of helping Jews leave Germany with property and advancing Zionism.[11] Hazit Ha'am attacked Arlosoroff on June 9 and June 16, 1933, over his pursuit of the transfer of Jewish property from Nazi Germany.[9] This rhetoric formed part of the political context of the suspicions following his murder, not evidence that the group committed it.[9]
The 1933–34 murder proceedings deepened divisions within the Yishuv and the Zionist movement.[12] Many Labor movement members saw evidence of criminal fascist tendencies among Revisionists, while Revisionists and other non-Labor circles denounced the affair as a “blood libel of Jews against Jews.”[12] Ahimeir denied plotting the murder, and the accusation against him was dropped; his subsequent imprisonment concerned the separate proceedings over his organizational activity.[5][9] Abraham Stavsky, another defendant, was convicted and subsequently acquitted by the Supreme Court for lack of corroborating evidence.[12] A state commission concluded in 1985 that the murder could not be attributed to any political group and that neither the perpetrators nor their motive could be determined.[9]
