India
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by geographical area, the second most populous country and the largest democracy in the world. India has a coastline of over seven thousand kilometres, and borders Pakistan to the west, Nepal, the People's Republic of China and Bhutan to the north-east, and Bangladesh and Myanmar to the east. In the Indian Ocean, it is adjacent to the island nations of Sri Lanka, Maldives and Indonesia. Home to the Indus Valley Civilization, a centre of important trade routes and vast empires, India has long played a major role in human history. Hinduism, Sikhism, Buddhism and Jainism, all have their origins in India, while Islam and Christianity enjoy a strong cultural heritage. Colonised as part of the British Empire in the nineteenth century, India gained independence in 1947 as a unified nation after an intense struggle for independence. The country has one of the most diverse populations, wildlife, and geographical terrain and climate systems.
