Bhagat Singh’s life (September 28, 1907-March 23, 1931), work and thought were marked by an uncompromising struggle against colonialism and imperialism, together with radical opposition to capitalism, communalism and the caste system. This article is a spirited account of his life, his revolutionary activity, his ideals, his opinions and his legacy. It was on April 8, 1929 that Bhagat Singh and B K Dutt threw non-lethal bombs in the Central Assembly with a view “to make the deaf hear”, and raised the slogans “Inquilab Zindabad” and “Down with Imperialism”, which caught the imagination of the Indian people. Perhaps at no other point in the life of India since 1947 has the reference to these two slogans become more important than today, as the country marks the hundredth birth anniversary of Bhagat Singh.
