Tamil Nadu (; Tamil: [ˈtamiɻ ˈnaːɽɯ] (listen), abbr. TN) is a state in southern India. It is the tenth largest Indian state by area and the sixth largest by population. Its capital and largest city is Chennai. 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 state lies in the southernmost part of the Indian peninsula, and is bordered by the Indian union territory of Puducherry and the states of Kerala, Karnataka, and Andhra Pradesh, as well as an international maritime border with Sri Lanka. It is bounded 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 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 state's cuisine, culture, and architecture. After the fall of the Kingdom of Mysore, the British colonised the region and administered it as part of the Madras Presidency, headquartered at the city of Madras, now known as Chennai. After India's 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$310 billion) and has the country's 11th-highest GSDP per capita of ₹225,106 (US$2,800). 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 state's GDP. Its tourism industry is the largest among the Indian states. The Tamil film industry plays an influential role in the state's popular culture.

Kutch district (also spelled as Kachchh) is a district of Gujarat state in western India, with its headquarters (capital) at Bhuj. Covering an area of 45,674 km2, it is the largest district of India. The area of Kutch District is larger than the entire area of states like Haryana (44,212 km2) and Kerala (38,863 km2). The population of Kutch is about 2,092,371. It has 10 talukas, 939 villages and 6 municipalities. The Kutch district is home to the Kutchi people who speak the Kutchi language. Kutch literally means something which intermittently becomes wet and dry; a large part of this district is known as Rann of Kutch which is shallow wetland which submerges in water during the rainy season and becomes dry during other seasons. The same word is also used in Sanskrit origin for a tortoise. The Rann is known for its marshy salt flats which become snow white after the shallow water dries up each season before the monsoon rains. The district is also known for ecologically important Banni grasslands with their seasonal marshy wetlands which form the outer belt of the Rann of Kutch. Kutch District is surrounded by the Gulf of Kutch and the Arabian Sea to the south and west, while the northern and eastern parts are surrounded by the Great and Little Rann (seasonal wetlands) of Kutch. It is also next to the Border with Pakistan. When there were not many dams built on its rivers, the Rann of Kutch remained wetlands for a large part of the year. Even today, the region remains wet for a significant part of year. The district had a population of 2,092,371 as of 2011 census, of which 30% were urban. Motor vehicles registered in Kutch district have a registration number starting with GJ-12. The district is well connected by road, rail and air.
