In 1912, Rash Behari Bose made his dramatic entrance into India's anti-colonial freedom movement when he orchestrated a bomb attack against the British viceroy during a public procession in Delhi. Forced to\nflee his homeland, Bose settled in Japan, becoming the most influential Indian in Tokyo and earning the affectionate title 'Sensei' among Japanese youth, military personnel, and far-right ultranationalists.Throughout the 1920s and 1930s, Bose remained a perpetual thorn in the side of the British Empire as he builtand maintained a global network of anti-colonialists, radicals, smugglers, and intellectuals. After siding with Imperial Japan against his British adversaries during the Second World War, Bose died in 1945-just two years before India gained independence.A complex, controversial, and often contradictory figure, Bose has been described as a committed democrat, an authoritarian, an advocate of religious harmony, a Hindu chauvinist, an anti-communist, a political pragmatist, an idealist, a Japanese collaborator, an anti-racist, a cultural conservative, aPan-Asianist, an Indian nationalist, and much more. Drawing on extensive archival researchfrom India, Japan, and the UK, this refreshing new biography brings to life the largely forgotten story of one of twentieth-century Asia's most daring revolutionaries.
