Introduction

Abstract

The disproportionate historical contribution of Jews to the political Left has been well documented. Both as individual theorists and activists of the stature of Karl Marx, Leon Trotsky, Rosa Luxemburg, Léon Blum and Emma Goldman, and as organized mass labour movements in, for example, revolutionary Russia and early–mid-20th century Warsaw, Amsterdam, Paris, Toronto, Buenos Aires, New York and London, Jews have been conspicuous for their socialist and communist affiliations.
