Tamil Nadu (; Tamil: [ˈtamiɻ ˈnaːɽɯ] (listen), abbr. TN) is a state in southern India. The tenth largest Indian state by area and the sixth largest by population, Tamil Nadu is the home of the Tamil people, whose Tamil language—one of the longest surviving classical languages in the world—is widely spoken in the state and serves as its official language. The capital and largest city is Chennai.
Located in the southernmost part of the Indian peninsula, Tamil Nadu is bordered by the Indian union territory of Puducherry and states of Kerala, Karnataka, and Andhra Pradesh, as well as an international maritime border with Sri Lanka. Naturally, it is bound by the Western Ghats in the west, the Eastern Ghats in the north, the Bay of Bengal in the east, the Gulf of Mannar and the Palk Strait to the south-east, and the Indian Ocean in the south.
The at-large Tamilakam region that has been inhabited by Tamils was under several regimes, such as the Sangam era rulers of the Chera, Chola, and Pandya clans, the Pallava dynasty, and the later Vijayanagara Empire, all of which shaped the states cuisine, culture, and architecture. Europeans began establishing trade ports in the 17th century, and eventually the British colonized the majority of the region, administering it as the Madras Presidency. After Indias Independence in 1947, the Madras State came into existence, whose borders were linguistically redrawn by the States Reorganisation Act, 1956, losing territory to Kerala, Karnataka and Andhra Pradesh. The state was renamed as Tamil Nadu in 1969. It is home to a number of historic buildings, multi-religious pilgrimage sites, hill stations and three World Heritage Sites.The economy of Tamil Nadu is the second-largest in India, with a gross state domestic product (GSDP) of ₹24.85 lakh crore (US billion) and has the countrys 11th-highest GSDP per capita of ₹225,106 (US,800). It ranks 11th among all Indian states in human development index. Tamil Nadu is the most urbanised state in India, and one of the most industrialised states; the manufacturing sector accounts for more than one-third of the states GDP. Its tourism industry is the largest among the Indian states. The Tamil film industry plays an influential role in the states popular culture.
