Borochov, along with Nachman Syrkin is considered a father of socialist Zionism. Borochov's ideas were influential in convincing Jewish youth from Europe to move to Palestine. However, Borochov's theories remained most influential in Eastern Europe, where they formed the basis of the Left Poale Zionist movement which was active in Poland during the interwar years. Indeed, Borochov's vision of class struggle in Palestine was widely viewed as untenable by the 1910s, with Jewish migrants to Palestine struggling to establish an economic foothold and with interclass cooperation seemingly necessary, and his theories dimmed in popularity there. Borochov, for years an advocate for a doctrinaire Marxist Zionism, himself seemed to repudiate his former vision of class struggle in Palestine in speeches towards the end of his life. Borochov insisted that he was a Social Democrat, but Borochov's Left Poale Zion followers continued to vigorously advocate class struggle both in Palestine and eastern Europe, supporting the February Revolution of 1917.
