What is the school of thought whose motto is "There is no god, and the universe is matter"?

Communism is a materialistic, atheistic intellectual doctrine that emerged in Germany at the hands of Marx and Engels, and was embodied in the Bolshevik Revolution in Russia, then put into practice by Lenin. Among its most important ideas are the denial of God's existence, that matter is the basis of everything, the interpretation of history through class struggle, the combating of religions and private ownership, the assertion of the relativity of morals, and that the end justifies the means. Communism collapsed in its strongholds after the failure of applying its ideas. The principles of communism are considered disbelief and it is not permissible to believe in or adhere to them.
