Bhagat Singh was an Indian revolutionary freedom fighter who was hanged to death by British colonisers at the age of 23 years. Fondly known as 'Shaheed (martyr) Bhagat Singh', he is considered a national hero of India's freedom struggle against colonial rule. As a teenager, Bhagat Singh popularised the slogan of ‘Inquilab Zindabad’ which eventually became the catchphrase of the Indian independence movement.
