Karl Marx: an overview of his biographies

Many books and articles were written about the thought of Karl Marx, but much fewer were written about Marx's life per se. This article aims at providing an overview of the biographies of Marx written so far, covering from the first ones in the nineteenth-century to the ones in the twenty-first century. We will analyze the evolution of these biographies both in terms of formal-methodological quality and in terms of new factual evidence provided by them about Marx's life.
