Mangal Pandey is widely regarded as the first martyr of the Revolt of 1857, which is also known as the First War of Indian Independence. He was a sepoy in the 34th Bengal Native Infantry and played a pivotal role in sparking the rebellion. On 29th March 1857, Mangal Pandey attacked British officers at the barracks in Barrackpore, and he was subsequently arrested and executed on 8th April 1857. His actions are seen as the catalyst that led to the widespread uprising against British rule.
