\[N]o credit is due to me fordiscovering the existence of classes in modern society or the struggle between them.\nLong before me bourgeois historians had described the historical development of this class struggle and bourgeois economists, the economic anatomy of classes. What I did that was new was to prove:\n1. that the existence of classes is only bound up with the particular, historical phases in the development of production, \n2. that the class struggle necessarily leads to the\ndictatorship of the proletariat,\n3. that this dictatorship itself only constitutes the transition to the abolition of all classes and to a classless society.\\nKarl Marx
