, founder of Revisionist Zionism After
World War I, Jabotinsky was elected to the first legislative assembly in the
Yishuv, and in 1921 he was elected to the Executive Council of the
Zionist Organization (known as the World Zionist Organization after 1960). He quit the latter group in 1923, thanks mainly to differences of opinion with its chairman,
Chaim Weizmann. In 1925, Jabotinsky formed the
Revisionist Zionist Alliance, in the
World Zionist Congress to advocate his views, which included increased cooperation with Britain on transforming the entire
Mandate for Palestine territory, including Palestine itself and Transjordan, on opposite sides of the
Jordan River, into a sovereign Jewish state, loyal to the
British Empire. To this end, Jabotinsky advocated for mass Jewish immigration from Europe and the creation of a second
Jewish Legion to guard a nascent Jewish state at inception. Jabotinsky wished to convince Britain that a Jewish state would be in the best interest of the British Empire, perhaps even an autonomous extension of it in the
Middle East. When, in 1935, the Zionist Organization failed to accept Jabotinsky's program, he and his followers seceded to form the
New Zionist Organization. The NZO rejoined the ZO in 1946. The Zionist Organization was roughly composed of
General Zionists, who were in the majority, followers of Jabotinsky, who came in a close second, and
Labour Zionists, led by
David Ben-Gurion, who comprised a minority yet had much influence where it mattered, in the
Yishuv. Despite its strong representation in the Zionist Organization, Revisionist Zionism had a small presence in the Yishuv, in contrast to Labour Zionism, which was dominant among
kibbutzim and workers, and hence the settlement enterprise. General Zionism was dominant among the
middle class, which later aligned itself with the Revisionists. In the Jewish Diaspora, Revisionism was most established in
Poland, where its base of operations was organized in various political parties and Zionist Youth groups, such as
Betar. By the late 1930s, Revisionist Zionism was divided into three distinct ideological streams: the "Centrists", the
Irgun, and the "Messianists". Jabotinsky later argued for establishing a base in the Yishuv and developed a vision to guide the Revisionist movement and the new Jewish society on economic and social policy centered around the ideal of the Jewish middle class in Europe. Jabotinsky believed that basing the movement on a philosophy contrasting with the socialist-oriented Labour Zionists would attract the support of the General Zionists. In line with this thinking, the Revisionists transplanted into the Yishuv a youth movement, Betar. They also set up a paramilitary group, Irgun, a labour union, the
National Labor Federation in Eretz-Israel, and health services. The latter were intended to counteract the increasing hegemony of Labour Zionism over community services via the
Histadrut and address the Histadrut's refusal to make its services available to Revisionist Party members. ==Irgun Tsvai Leumi==
