After the GJLB came out against Zionism in 1901, Zionist circles of socialist workers and intellectuals not only established themselves in Russia, but also in many other countries including the US, the UK and Austria-Hungary.
At the end of 1905, a congress was organised which helped define the movement’s goals. In 1906, the Jewish Socialist-Democratic Labour Party founded Poale Zion. The movement later split over issues such as Zionism and the movement’s relationship to the Socialist International. Quite a few of its protagonists later joined communist parties in Eastern Europe. Poale Zion was particularly important for the development of the Communist Party of Israel and the history of the Jewish Left as a whole.
