This scholarly biography focuses on the early years of the influential Russian Jewish author and pioneer of Revisionist Zionism. In the first decades of the twentieth century, Russia was a place of intense social strife and political struggle. Vladimir Yevgenyevich "Ze'ev" Jabotinsky, who would go on to become the founder of the Revisionist Zionism Alliance in 1925, was already a Zionist leader and Jewish public intellectual. Although previously glossed over, these early years were crucial to Jabotinsky's development as a thinker, politician, and Zionist. In this enlightening biography, Brian Horowitz focuses on Jabotinsky's commitments to Zionism and Palestine as he embraced radicalism and fought against the suffering brought upon Jews through pogroms, poverty, and victimization. Horowitz also defends Jabotinsky against accusations that he was too ambitious, a fascist, and a militarist. As Horowitz delves into the years that shaped Jabotinsky's social, political, and cultural orientation, an intriguing psychological portrait emerges.
