Labor Zionism (Hebrew: ציונות סוציאליסטית, romanized: tziunut socialistit) is the left-wing, socialist variant of Zionism. For many years, it was the most significant tendency among Zionists and Zionist organizations, and was seen as the Zionist faction of the historic Jewish labour movements of Eastern Europe and Central Europe. Labor Zionism eventually developed local movements in most countries with sizable Jewish populations. Unlike the "political Zionist" tendency founded by Theodor Herzl and advocated by Chaim Weizmann, Labor Zionists did not believe that a Jewish state would be created by simply appealing to the international community or to powerful nations such as the United Kingdom, Germany, or the former Ottoman Empire. Rather, they believed that a Jewish state could only be created through the efforts of the Jewish working class making aliyah to the Land of Israel and raising a country through the creation of a Labor Jewish society with rural kibbutzim and moshavim, and an urban Jewish proletariat. Major theoreticians of the Labor Zionist movement included Moses Hess, Nachman Syrkin, Ber Borochov, and Aaron David Gordon; and leading figures in the movement included David Ben-Gurion, Golda Meir, and Berl Katznelson. Labor Zionist parties, most notably Mapai and its successor, the Israeli Labor Party, dominated Israeli politics during the state's first three decades.
