Marx's ideas have had a profound impact on world politics and intellectual thought. Followers of Marx have often debated among themselves over how to interpret Marx's writings and apply his concepts to the modern world. The legacy of Marx's thought has become contested between numerous tendencies, each of which sees itself as Marx's most accurate interpreter. In the political realm, these tendencies include Leninism, Marxism–Leninism, Trotskyism, Maoism, Luxemburgism and libertarian Marxism. Various currents have also developed in academic Marxism, often under influence of other views, resulting in structuralist Marxism, historical Marxism, phenomenological Marxism, analytical Marxism and Hegelian Marxism.
