Vladimir Jabotinsky, (born 1880, Odessa, Russian Empire [now in Ukraine]—died Aug. 3, 1940, near Hunter, N.Y., U.S.), Zionist leader, journalist, orator, and man of letters who founded the militant Zionist Revisionist movement that played an important role in the establishment of the State of Israel.
Jabotinsky began his career in 1898 as a foreign correspondent, but his popularity as a journalist led to his recall to Odessa in 1901 as an editorial writer. By 1903 Jabotinsky began to expound Zionist views for the restoration and creation of a Jewish national state in Palestine both in his writings and in his oratory, of which he was a master. During the next decade, he continued to work as a journalist while traveling in Europe and crystallizing his Zionist views, which tended to be uncompromising and political, rather than cultural.
