Trotskyism is the theory of Marxism as advocated by Leon Trotsky. Trotsky considered himself an orthodox Marxist and Bolshevik-Leninist, arguing for the establishment of a vanguard party. His politics differed sharply from those of Stalinism, most importantly in declaring the need for an international proletarian revolution (rather than socialism in one country) and unwavering support for a true dictatorship of the proletariat based on democratic principles.
Trotsky was, together with Lenin, the most important and well-known leader of the Russian Revolution and the international Communist movement in 1917 and the following years. Nowadays, numerous groups around the world continue to describe themselves as Trotskyist, although they have developed Trotsky's ideas in different ways. A follower of Trotskyist ideas is usually called a "Trotskyist" or (in an informal or pejorative way) a "Trotskyite" or "Trot".[1]
