According to the Marxism-Leninism Study Guide:
“Marxism-Leninism is the synthesis and summation of the historic experiences of the revolutionary struggles of working and oppressed people against capitalism and imperialism for more than 160 years, and as such it is a weapon to be used by working and oppressed people in their struggles for emancipation, liberation, and the building of a new world. As Stalin has said, Marxism-Leninism is not a dogma but a guide to action.”
Marxism-Leninism informs and shapes the communist movement according to the specific conditions and circumstances of every country that it exists in. It allows each communist party and activist to adapt to their exact environments while staying firmly planted in a common, comprehensive worldview.
Marxism-Leninism is an advanced science, an empirical ideology based on the theories of dialectical materialism, political economy and class struggle.
