Bhagat Singh was an Indian anti-colonial revolutionary, who participated in the mistaken murder of a junior British police officer in December 1928 in what was to be retaliation for the death of an Indian nationalist. He later took part in a largely symbolic bombing of the Central Legislative Assembly in Delhi and a hunger strike in jail, which—on the back of sympathetic coverage in Indian-owned newspapers—turned him into a household name in the Punjab region, and after his execution at age 23 into a martyr and folk hero in Northern India. Borrowing ideas from Bolshevism and anarchism, the charismatic Singh electrified a growing militancy in India in the 1930s, and prompted urgent introspection within the Indian National Congress's nonviolent but eventually successful campaign for India's independence

Bhagat Singh was born into a Punjabi Jat Sikh family on 27 September 1907 in the village of Banga in the Lyallpur district of the Punjab in what was then British India and is today Pakistan; he was the second of seven children—four sons, and three daughters—born to Vidyavati and her husband Kishan Singh Sandhu. Bhagat Singh's father and his uncle Ajit Singh were active in progressive politics, taking part in the agitation around the Canal Colonization Bill in 1907, and later the Ghadar Movement of 1914–1915.
