After the Revolt of 1857, the British officers of the Indian Army, particularly those who had served in the First and Second Afghan Wars, began to give currency to the Martial Races Theory. This theory was that some races and communities among Indians were naturally warlike, and more suited to warfare than others. A major proponent of this theory was Lord Roberts, who became Commander-in-Chief of the Indian Army in the November 1885. There was a gradual "Punjabisation" of the Indian Army to the detriment of the other communities. The final blow for the Mahar troops came in 1892, when it was decided to institute "class regiments" in the Indian Army. The Mahars were not included in these class regiments, and it was notified that the Mahars, among with some other classes, were no longer to be recruited in the Indian army. The Mahar troops, who included 104 Viceroy's Commissioned Officers and a host of Non-commissioned officers and Sepoys were demobilised. This event was regarded by the Mahars as a betrayal of their loyalty by a government they had served for over a hundred years.
