Rajguru was an Indian freedom fighter known for his role in the struggle against British colonial rule. Born on August 24, 1908, in Pune, he was a member of the revolutionary group Hindustan Socialist Republican Association (HSRA). Rajguru was deeply influenced by the ideas of nationalism and sought to inspire others to join the fight for India's independence. He is best remembered for his involvement in the assassination of a British police officer, which aimed to avenge the death of fellow revolutionary Lala Lajpat Rai. Rajguru, along with Bhagat Singh and Sukhdev, was arrested and later executed on March 23, 1931, becoming a martyr in the quest for freedom.
