Marxism, also known as conflict theory, was originated by Karl Marx and focuses on the struggle between capitalists and the working class. Some core ideas of Marxism include the concept of class conflict between the bourgeoisie (capitalists who own the means of production) and the proletariat (working class who do not own the means of production). Marx argued that this conflict would inevitably lead to revolution and the establishment of a communist, stateless, classless society.
