Peter A. Kropotkin was the leading theorist and activist of communist anarchism. Despite his noble background and the associated social privileges, Kropotkin chose to forgo a predetermined career in public service and decided to dedicate his life to the revolutionary cause. Kropotkin's political ideas remain remarkably relevant. Decentralized autonomous economic units, mutual aid, autonomous thinking and action, equality at all levels, and need-based production instead of capitalism possess a universal character that is applicable to the present day.
