The geographic regions, north and south of the Vindhya range known as ‘PanchAryas’ and ‘PanchDravidas’ respectively were mischievously distorted to create racial divide among people to weaken the country’s unity, the Governor said.
The term Dravidar or Dravidian represented regions including those in present-day Maharashtra, Andhra Pradesh, Telangana, Karnataka and Kerala.

What is Vellore Mutiny,1806

The Vellore Mutiny predated the Indian Revolt of 1857 by about 50 years. It erupted on 10^th July 1806 in Vellore, present-day Tamil Nadu, and lasted only for a day, but it was brutal and shook the British East India Company. It was the first major mutiny by the Indian sepoys in the East India Company.
The immediate causes of the mutiny revolved mainly around resentment felt towards changes in the sepoy dress code, introduced in November 1805. Hindus were prohibited from wearing religious marks on their foreheads while on duty, and Muslims were required to shave their beards and trim their moustaches.
In addition General Sir John Craddock, Commander-in-Chief of the Madras Army, ordered the wearing of a round hat resembling that associated at the time with both Europeans in general and with Indian converts to Christianity. The new headdress included a leather cockade and was intended to replace the existing turban.
