Answer:
The theory of communism was advanced by Karl Marx.
Explanation:
Karl Marx was a German political philosopher, economist, and influential social theorist of Jewish descent. Although he discussed many topics in his career as a journalist and philosopher, he is best known for his analysis of history in terms of class conflict. His philosophy is summed up by the assertion that the interest of capitalists and employees is completely contradictory. His most famous work is Das Kapital, which analyzes 19th century capitalism; it is considered the fundamental text of Communism and Marxism. Marx collaborated on pieces of his work with the industrialist Friedrich Engels, another German who supported Marx financially and helped edit Das Kapital. With him Marx wrote The Communist Manifesto in 1848, one of the most influential political manuscripts ever.
