The political philosophy associated with Leon Trotsky.
Form of Marxism advocated by Leon Trotsky. Its central concept is that of permanent revolution. In his view a proletarian revolution, leading to a socialist society, could not be achieved in isolation, so it would be necessary to spark off further revolutions throughout Europe and ultimately worldwide. This was in direct opposition to the Stalinist view that socialism should be built and consolidated within individual countries.
Trotskyism developed in an attempt to reconcile Marxist theory with actual conditions in Russia in the early 20th century, but it was never officially accepted within the USSR. Instead it found much support worldwide, primarily in Third World countries, and the Fourth International, which Trotsky founded 1938, has sections in over 60 countries.
