Hideki Tojo (東條 英機, Tōjō Hideki December 30, 1884 – December 23, 1948) was a Japanese politician, general of the Imperial Japanese Army (IJA), and convicted war criminal who served as prime minister of Japan and president of the Imperial Rule Assistance Association for most of World War II. He assumed several more positions including chief of staff of the Imperial Army before ultimately being removed from power in July 1944. During his years in power, his leadership was marked by extreme state-perpetrated violence in the name of Japanese ultranationalism, much of which he was personally involved in.
