Final answer:
Marx believed that a violent revolution would occur when conflicts between different social classes reached a breaking point. The material conditions for this revolution would include a large and self-aware working class and an economic crisis caused by overproduction. Once these conditions were met, the proletariat would rise up and take control of the means of production, leading to a more egalitarian society.
Step-by-step explanation:
According to sociologist and philosopher Karl Marx, a violent revolution would occur as the result of conflicts between different social classes. Marx believed that these conflicts, or 'class antagonisms', were a natural part of history and occurred when one class dominated another. In order for a violent revolution to take place, Marx argued that the material conditions for socialism would have to be present, such as a large and self-aware proletariat (working class) and an economic crisis caused by overproduction. Once these conditions were met, the proletariat would rise up and take over the means of production, leading to a more egalitarian society.
