Revisionist Maximalism was a short-term Jewish fascist ideology which was part of the Brit HaBirionim faction of the Zionist Revisionist Movement (ZRM) created by Abba Ahimeir. Revisionist Maximalists strongly supported the Italian fascist regime of Benito Mussolini and wanted the creation of an Israel based on fascist principles. The Revisionist Maximalists became the largest faction in the ZRM in 1930 but collapsed in support in 1933 after Ahimeir's controversial decision to support Nazi Germany due to its fascist and anti-communist stances, while opposing their antisemitic policies. After facing outrage, Ahimeir reversed his position shortly afterwards, with Revisionist Maximalists attacking German consulates, but support for Ahimeir did not recover and the Revisionist Maximalists collapsed until they were recreated in 1938 under new leadership.
The label of "fascist" has nevertheless to be regarded with reserves because in that period as later it was used often abusively in the disputes between opposed political nonfascist fractions, as in the 1930s even the Social Democrat parties were accused by Stalin and the communists of being "fascists" or "social-fascists". În the same way in Palestine Revisionist Zionists themselves were often qualified in the 1930s as "fascists" by the Labor Zionist leaders and the Revisionists attacked the social democratic dominated General Confederation of Labor (Histadrut) and Ben Gurion by using of terms like "Red Svastika" and comparisons with fascism and Hitler. Also, not every territorial maximalistic revendications or paramilitary practices were in the modern history identical with fascist ideology, they could be also be found among communists, social democrats, or other kinds of nationalists.
The ideology and political faction of Revisionist Maximalism was officially created in 1930 by Abba Ahimeir, a Jewish historian, journalist, and politician, who called for the Zionist Revisionist Movement (ZRM) to adopt the fascist principles of the regime of Benito Mussolini in Italy to create an integralist "pure nationalism" amongst Jews. Ahimeir was originally a member of the Jewish Labour movement who supported the October Revolution in Russia in 1917, and called for Jews to have their "own 1917" and spoke of the need for an October Revolution in Zionism. However Ahimeir grew disillusioned with Russian Bolshevism which he began to see as a Russian nationalist movement rather than a movement to promote international class struggle. Having become disillusioned with communism, Ahimeir grew nationalistic after the Arab-Jewish violence occurred in the British Mandate of Palestine from 1928 to 1929. Revisionist Maximalism rejects communism, humanism, internationalism, liberalism, pacifism and socialism; condemned liberal Zionists for only working for middle-class Jews rather than the Jewish nation as a whole. After the rise of anti-Jewish violence in the British Mandate of Palestine one year prior, support for the Brit HaBirionim faction of the ZRM soared, Brit HaBirionim quickly became the largest faction within the ZRM in 1930.
