At the time of the founding of the Fourth International in 1938, Trotskyism was a mass political current in Vietnam, Sri Lanka and slightly later Bolivia. There was also a substantial Trotskyist movement in China which included the founding father of the Chinese communist movement, Chen Duxiu, amongst its number. Wherever Stalinists gained power, they prioritised hunting down Trotskyists and treated them as the worst enemies.
