Marx

Marx has been described as one of the most influential figures of the modern era, and his work has been both lauded and criticised. Marxism has exerted major influence on socialist thought and political movements, with Marxist schools of thought such as Marxism–Leninism and its offshoots becoming the guiding ideologies of revolutions that took power in many countries during the 20th century, forming communist states. Marx's work in economics has had a strong influence on modern heterodox theories of labour and capital, and he is often cited as one of the principal architects of modern sociology.
