Tan Malaka (1894 - February 21, 1949) was an Indonesian nationalist activist and communist leader. A staunch critic of both the colonial Dutch East Indies government and the republican Sukarno administration that governed the country after the Indonesian National Revolution, he was also frequently in conflict with the leadership of the Communist Party of Indonesia (PKI), Indonesia's primary radical political party in the 1920s and again in the 1940s. A political outsider for most of his life, Tan Malaka spent a large part of his life in exile from Indonesia, and was constantly threatened with arrest by the Dutch authorities and their allies. Despite this apparent marginalization, however, he played a key intellectual role in linking the international communist movement to Southeast Asia's anti-colonial movements. He was declared a "hero of the national revolution" by act of Indonesia's parliament in 1963.
