Challenging orthodox Marxism while expanding the limits of traditional Marxism, Revisionist Marxism reinterprets the Marxist theory, offering pragmatic and flexible concepts amidst the dynamic capitalist society. It emerged in the 20th century against the rigid views advanced in Soviet Russia. Revisionist Marxism expands beyond economic determinism and offers complex ways of how society works while sticking with Marxism and keeping it relevant in changing times. Louis Althusser is the most recent theoretician who provided a rich theoretical base for flexible but strictly Marxist revisionist thinking.
