Marxist–Leninist atheism
Marxist–Leninist atheism, also known as Marxist–Leninist scientific atheism, is the antireligious element of Marxism–Leninism. Based on a dialectical-materialist understanding of humanity's place in nature, Marxist–Leninist atheism proposes that religion is the opium of the people; thus, Marxism–Leninism advocates atheism, rather than religious belief.
