Tamil Nadu is the name given to the Tamil-speaking region of what was previously known as the Madras State of the British Empire in India. The Tamils are particularly proud of the Dravidian culture and language, and they have been particularly vocal in their opposition to efforts by the government to make Hindi, the only official language of the country.
