The numbers and titles of the battalions changed during the successive reorganizations of the Madras Presidency Army, the British Indian Army and the Indian Army during the 18th, 19th and 20th centuries. The names changed from Coast Sepoys to Carnatic Infantry, Madras Native Infantry, Punjabis and finally to the Punjab Regiment. After the Indian Rebellion of 1857, the new colonial administration applied the martial races concept, following which north Indian soldiers overwhelmingly supplanted the south Indians. The regiment was eventually renamed to the Punjab Regiment. Currently, it has 76 battalions.
