Communist theory means envisioning of a social system in which people live and work in self-sufficient, self-reliant communes. But living as communes is not a new thing or idea. Through the ages, people have lived in communes, that too in well organized communes. But aristocracy, feudalism and industrial revolution somewhat displaced this ancient social structure, therefore when Karl Marx and Freidrich Engels came up with a similar but more politiaclly stable theory in the modern age they began to be considered as reinventors of communism.
The Communist view is that Communism has no classes and hence no role for government.
Communism is a form of socialism developed by Karl Marx, who wrote the Communist Manifesto.
Karl Marx
The communist theory of government was primarily developed by Karl Marx and Friedrich Engels in the mid-19th century. Their ideas were articulated in key works such as "The Communist Manifesto" (1848) and "Das Kapital" (1867). Marx and Engels argued for the establishment of a classless society through the abolition of private property and the means of production being owned collectively. Their theories laid the foundation for various communist movements and ideologies that followed.

Friedrich Engels helped develop that theory and wrote about it in their book "The Communist Manifesto." Although that book was published under both their names, Engels always gave full credit for the theory to Marx.
The theory of the Communist Manifesto was supported by political parties that identified as communist or socialist, such as the Communist Party and Socialist Party. These parties promoted the ideas of class struggle, workers' rights, and the eventual establishment of a classless society.
Adam Smith developed the theory of classical capitalism.
john dalton developed the atomic theory , which he published in 1803
Francis Galton developed the theory of Eugenics
Karl Marx and Friedrich Engels were the primary figures behind Marxism. They developed the theory and ideology of communism through their collaborative works, including the Communist Manifesto published in 1848.
