Chandrasekhar Azad (1906-1931) was an Indian nationalist who led a band of activists during India's freedom movement. Azad joined the Indian National Congress at a young age. Before long, the Congress glorified him as a hero and he became popular among people.
Azad became frustrated by Gandhi's suspension of the Non Cooperation Movement in February 1922, after policemen were killed by a crowd at Chauri Chaura. He joined the extreme Hindustan Republican Association (HRA), and started taking an interest in violent crimes, notably the Kakori train theft (1925) and the revenge killing of a British cop (1928). Azad's death was the result of an unfortunate betrayal. He died in a gun fight bravely fighting against the police.
