Labor Zionism or Socialist Zionism (Hebrew: צִיּוֹנוּת סוֹצְיָאלִיסְטִית, translit. tsionut sotsialistit) can be described as the major stream of the left wing of the Zionist movement. It was, for many years, the most significant tendency among Zionists and Zionist organizational structure. It saw itself as the Zionist sector of the historic Jewish labor movements of Eastern and Central Europe, eventually developing local units in most countries with sizeable Jewish populations.
