Trotskyism in Vietnam
Trotskyism in Vietnam (Vietnamese: Trăng-câu Đệ-tứ Đảng) was represented by those who, in left opposition to the Indochinese Communist Party (ICP) of Hồ Chí Minh, identified with the call of Leon Trotsky to re-found "vanguard parties of proletariat" on principles of "proletarian internationalism" and of "permanent revolution". Active in the 1930s in organising the Saigon waterfront, industry and transport, Trotskyists presented a significant challenge to the Moscow-aligned party in Cochinchina.
