"Communism was an economic-political philosophy founded by Karl Marx and Friedrich Engels in the second half of the 19th century. Marx and Engels met in 1844, and discovered that they had similar principles. In 1848 they wrote and published "The Communist Manifesto." They desired to end capitalism feeling that it was the social class system that led to the exploitation of workers. The workers that were exploited would develop class consciousness. Then there would be a fundamental process of class conflict that would be resolved through revolutionary struggle. In this conflict, the proletariat will rise up against the bourgeoisie and establish a communist society. Marx and Engels thought of the proletariat as the individuals with labor power, and the bourgeoisie as those who own the means of production in a capitalist society. The state would pass through a phase, often thought of as a socialism, and eventually settle finally on a pure communist society. In a communist society, all private ownership would be abolished, and the means of production would belong to the entire community. In the communist movement, a popular slogan stated that everyone gave according to their abilities and received according to their needs. Thus, the needs of a society would be put above and beyond the specific needs of an individual."
