Chandra Shekhar Azad secretly reorganized the Hindustan Republican Association (HRA) with Bhagat Singh and other rebels in 1928 and changed its name to Hindustan Socialist Republican Association (HSRA)'
The HRA was founded in October 1924 in Kanpur by Ramprasad Bismil, Jogesh Chandra Chatterjee and Sachin Sanyal, with an aim to organise an armed revolution to overthrow the colonial government and establish in its place the Federal Republic of United States of India whose basic principle would be an adult franchise.
The HRA formed centres, besides Allahabad, Agra, Kanpur, Varanasi, Lucknow,
Shahjahanpur, and Saharanpur.
