Sukhdev Thapar was born in Ludhiana, Punjab, British Raj on 15 May 1907 to Ramlal Thapar and Ralli Devi. He belonged to a Punjabi Khatri family of the Hindu community and he was brought up by his uncle Lala Achintram after the death of his father. Revolutionary activities

Hindustan Socialist Republican Association 
Sukhdev Thapar was a member of the Hindustan Socialist Republican Association and the Naujawan Bharat Sabha. He also initiated revolutionary movements in Punjab and other regions of northern India. He was the chief of the Punjab unit of the HSRA and was instrumental in making decisions. Sukhdev took part in a number of revolutionary events, including a prison hunger strike in 1929. He is widely known for his assaults in the Lahore Conspiracy Case (1929–1930). He is well known for his role in the assassination of Assistant Superintendent of Police J. P. Saunders on 17 December 1928, by Bhagat Singh and Shivaram Rajguru, the assassination carried out in retaliation for the senior leader Lala Lajpat Rai's horrific death. Lahore Conspiracy Case 
Sukhdev was the main suspect in the 1929 Lahore Conspiracy Case, which was officially titled "Crown versus Sukhdev and others." The case's first information report (FIR), submitted in April 1929 by Hamilton Harding, Senior Superintendent of Police, in the court of R.S. Pandit, Special Magistrate, lists Sukhdev as accused number one. It describes him as Swami alias peasant, son of Ram Lal, Thapar Khatri caste. Sukhdev and his companions were detained, found guilty, and given a death sentence following the bombings of the Central Assembly Hall in New Delhi on 8  April 1929. Thapar, Bhagat Singh, and Shivaram Rajguru were all hanged on 23 March 1931, in Lahore Central Jail. Their remains were surreptitiously burned on the banks of the Sutlej River. Reactions to the executions 
The executions were highly publicised in the news, especially because they occurred on the day of the Indian National Congress's annual convention in Karachi. According to the New York Times:
 In an editorial for his daily Janata, B. R. Ambedkar blamed the British government for the killings, despite widespread popular sympathy for the revolutionaries. He believed that the decision to execute the trio was not made in the spirit of justice, but rather out of fear of a backlash from the Conservative Party and a need to please public opinion in England. Conservatives saw the Gandhi-Irwin Pact, signed just weeks before the execution, as undermining the authority of the British Empire. If the British government or the Viceroy of India had changed the death sentences of the trio convicted of murdering a British police officer in such a situation, it would have given conservatives more ammunition to criticize the already weak British government in Parliament.
