How do i rewrite this in my own words?

Communism is a social structure and political ideology in which property is commonly controlled. Communism (written with a capital C) is a modern political movement that aims to overthrow capitalism via revolution to create a classless society where all goods are publicly owned. Karl Marx posited that communism would be the final stage in human society, which would be achieved through a proletarian revolution and only becoming possible after a socialist stage develops the productive forces, leading to a superabundance of goods and services.
