Marxism, one of the few philosophies that turned into an effective movement, not so long ago was the official ideology in one form or another of much of humanity. It was promulgated initially by the Soviet Union, then imposed on much of Central and Eastern Europe, later emerged in the People’s Republic of China, and gradually spread to other parts of Asia and even bits of Africa and Latin America. Although declining in its initial popularity, it still remains strong in several countries and is supported by numerous communist and other parties and countless individuals around the world. The A to Z of Marxism covers the history of Marxism and all its thinkers and schools of thought in a comprehensive manner. This is done, through a chronology, an introductory essay, a bibliography, and hundreds of cross-reference dictionary entries on basic terms and concepts, significant thinkers and doers, and also the parties and countries that followed it.
