Bhagat Singh was a Punjabi revolutionary, born on 28 September 1907 near Lyallpur in undivided India, who by his early twenties had become the sharpest mind of the Hindustan Socialist Republican Association (HSRA). In December 1928, to avenge the police lathi-charge that had killed the veteran leader Lala Lajpat Rai, Bhagat Singh, Rajguru and others shot dead the British police officer J.P. Saunders in Lahore. Then, on 8 April 1929, Bhagat Singh and Batukeshwar Dutt threw two low-intensity bombs into the Central Legislative Assembly in Delhi โ not to kill, but, in their words, 'to make the deaf hear' โ and calmly courted arrest, showering leaflets and shouting 'Inquilab Zindabad'. What followed was the long Lahore Conspiracy Case, a historic prison hunger strike for the rights of political prisoners, and on 23 March 1931 the execution of Bhagat Singh, Sukhdev and Rajguru at Lahore Central Jail. But the trial gave him a stage. Through court statements, letters and the essay 'Why I Am an Atheist', he argued for socialism, reason and mass revolution over blind heroism. He wanted the sound of the bomb to carry an argument, not just fear. That is why, nearly a century on, he is remembered as a thinker as much as a martyr.
