A study investigating how the founders of Marxism came to terms with the emergence of liberal democracy as a political force during their lifetimes. It examines how they defined democracy and how they evaluated the liberal constitutional state, what they would have expected from the emergence of a working class franchise and the rise, particularly in Germany, of a worker's political party. The author proposes the answers to these questions in clear, jargon-free language. His previous books, translated in several languages, include, "Karl Marx - The Early Texts", "The Young Hegelians and Karl Marx", "Marx before Marxism" and many others.
