Examine the quotes by Karl Marx and put his message in your own words on the right hand side. The history of all hitherto existing society is the history of class struggles. Freeman and slave, patrician and plebeian (Ancient Rome), lord and serf (Feudalism in Europe), guild-master and journeyman (Commercial Revolution in Europe). In a word, oppressor and oppressed, stood in constant opposition to one another, carried on an uninterrupted, now hidden, now open fight, a fight that each time ended, either in a revolutionary re-constitution of society at large, or in the common ruin of the social classes.
