India is a country in South Asia. It is the seventh-largest country by geographical area, the second-most populous country with over 1.2 billion people, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; Bhutan, the People's Republic of China and Nepal to the northeast; and Bangladesh and Burma to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; in addition, India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.
Home to the ancient Indus Valley Civilization 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 of the world's major religions—Hinduism, Buddhism, Jainism and Sikhism—originated here, whereas Zoroastrianism, Christianity and Islam arrived in the 1st millennium CE and also helped shape the region's diverse culture. Gradually annexed by the British East India Company from the early 18th century and colonized by the United Kingdom from the mid-19th century, India became an independent nation in 1947 after a struggle for independence which was marked by non-violent resistance led by Mahatma Gandhi.
India is the most populous democracy in the world. A parliamentary republic with a multi-party system, it has six recognised national parties, including the Indian National Congress and the Bharatiya Janata Party (BJP), and more than 40 regional parties. The Congress is considered centre-left or "liberal" in Indian political culture, and the BJP centre-right or "conservative". For most of the period between 1950 – when India first became a republic – and the late 1980s, the Congress held a majority in the parliament. Since then, however, it has increasingly shared the political stage with the BJP, as well as with powerful regional parties which have often forced the creation of multi-party coalitions at the Centre.
Traditional Indian society is defined by relatively strict social hierarchy. The Indian caste system describes the social stratification and social restrictions in the Indian subcontinent, in which social classes are defined by thousands of endogamous hereditary groups, often termed as jâtis or castes. Several influential social reform movements, such as the Brahmo Samaj, the Arya Samaj and the Ramakrishna Mission, have played a pivotal role in the emancipation of Dalits (or "untouchables") and other lower-caste communities in India. However, the majority of Dalits continues to live in segregation and are often persecuted and discriminated against.
India's official national sport is field hockey, administered by Hockey India. The Indian hockey team won the 1975 Hockey World Cup and 8 gold, 1 silver and 2 bronze medal at the Olympic games, making it one of the world's most successful national hockey teams ever. Cricket, however, is by far the most popular sport; the India cricket team won the 1983 and the 2011 World Cups, 2007 ICC World Twenty20, and shared the 2002 ICC Champions Trophy with Sri Lanka. Cricket in India is administered by the Board of Control for Cricket in India (BCCI) and domestic competitions include the Ranji Trophy, the Duleep Trophy, the Deodhar Trophy, the Irani Trophy and the NKP Salve Challenger Trophy. In addition, BCCI conducts the Indian Premier League, a Twenty20 competition.
