India, officially the Republic of India (Hindi: भारत गणराज्य Bhārat Gaṇarājya; see also other Indian languages), is a country in South Asia. It is the seventh-largest country by geographical area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the west, and the Bay of Bengal on the east, India has a coastline of 7,517 kilometres (4,700 mi). It is bordered by Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. India is in the vicinity of Sri Lanka, and the Maldives in the Indian Ocean.

Home to the Indus Valley Civilisation and a region of historic trade routes and vast empires, the Indian subcontinent was identified with its commercial and cultural wealth for much of its long history. Four major religions, Hinduism, Buddhism, Jainism and Sikhism originated here, while Zoroastrianism, Judaism, Christianity and Islam arrived in the first millennium CE and shaped the region's diverse culture. Gradually annexed by the British East India Company from the early eighteenth century and colonised by the United Kingdom from the mid-nineteenth century, India became an independent nation in 1947 after a struggle for independence that was marked by widespread non-violent resistance.

India is a republic consisting of 28 states and seven union territories with a parliamentary system of democracy. It has the world's twelfth largest economy at market exchange rates and the fourth largest in purchasing power. Economic reforms since 1991 have transformed it into one of the fastest growing economies; however, it still suffers from high levels of poverty, illiteracy, disease, and malnutrition. A pluralistic, multilingual, and multiethnic society, India is also home to a diversity of wildlife in a variety of protected habitats.

Tamil Nadu (Tamil: தமிழ்நாடு "Country of the Tamils", pronounced [t̪ɐmɨɻ n̪aːɽɯ]( listen)) is one of the 28 states of India. Its capital and largest city is Chennai (formerly known as Madras). Tamil Nadu lies in the southernmost part of the Indian Peninsula and is bordered by Puducherry (Pondicherry), Kerala, Karnataka and Andhra Pradesh. It is bound by the Eastern Ghats in the north, the Nilgiri, the Anamalai Hills, and Palakkad on the west, by the Bay of Bengal in the east, the Gulf of Mannar, the Palk Strait in the south east, and by the Indian Ocean in the south.




Tamil Nadu is the eleventh largest state in India by area (about the size of Greece) and the seventh most populous state. It is the fifth largest contributor to India's GDP[3] and the most urbanised state in India. The state has the highest number (10.56%) of business enterprises in India,[5] compared to the population share of about 6%. It is one of the foremost states in the country in terms of overall development.




The region has been the home of the Tamil civilization since at least 1500 BC, as attested by numerous archeological sites in and around Adichanallur. Its classical language Tamil has been in use in inscriptions and literature for 2500 years. Tamil Nadu is home to many natural resources, grand Hindu temples of Dravidian architecture, hill stations, beach resorts, multi-religious pilgrimage sites and eight UNESCO World Heritage Sites.
