Bhagat Singh was an Indian freedom fighter considered one of the most famous revolutionaries of the Indian independence movement. He was inspired to join the struggle for independence at a young age after witnessing the Jalianwala Bagh massacre. As a teenager, he studied European revolutionary movements and joined various revolutionary organizations in India. He became a leader of the Hindustan Republican Association and helped convert it to focus more on revolutionary activities. Bhagat Singh carried out a bomb attack on the British legislative assembly to protest against the British rule in India. He was later arrested, tried and hanged by the British authorities at the age of 23, becoming a martyr for the Indian independence movement.
