Kesatuan Melayu Muda (KMM: Young Malay Union).
Registering in 1938 in Kuala Lumpur as a social organization through lectures, group discussions, self-help, and self-study, the Kesatuan Melayu Muda was in fact a radical Malay Nationalist party. To insieders, KMM actually stood for Kesatuan Melayu Merdeka (Union of Independent Malaya) with primary objective of political independence for Malaya from British Colonial rule. KMM also strived to resolve Malay backwardness politically, economically, and socially that was blamed on British imperialism, archaic Malay feudalism. And the influx and presence of immigrant non-Malays in Tanah Melayu. Ibrahim Yaacob was KMM’s founder and president. Its radicalism and advocacy of Melayu Rayal Indonesia Raya, unity of the MalayArchipelago, earned KMM little support from Malay royalists and the bureaucratic elite. Prior to the Japanese invasion in December 1941, Ibrahim and other KMM members were arrested and KMM was banned by the British for collaboration with Japan. Vice President Mustapha Hussain on 14 January 1942 demanded that Japan grant independence to Malaya Instead, the Japanese proscribed KMM; many members joined the clandestine KMM Youth Front to continue the independence struggle during the Japanese Occupation (1941-1945).
