India is a country located in South Asia, officially designated as the Republic of India. It occupies a significant portion of the Indian subcontinent, bounded by the Indian Ocean to the south, the Arabian Sea to the southwest, and the Bay of Bengal to the southeast. The nation shares extensive land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. Geographically, it is the world's seventh-largest country by area and serves as a central hub for the region, situated near Sri Lanka and the Maldives in the Indian Ocean.

The history of the region spans millennia, with modern humans arriving from Africa approximately 55,000 years ago. Settled life emerged on the western margins of the Indus basin 9,000 years ago, evolving into the Indus Valley Civilisation by the third millennium BCE. Subsequent periods saw the rise of Hinduism, Buddhism, and Jainism, followed by the Maurya and Gupta Empires. The Delhi Sultanate and Mughal Empire later influenced the region before British Crown rule began in 1858. India gained independence in 1947 after a nationalist movement characterized by nonviolent resistance, becoming a federal republic in 1950.

The country is administratively divided into 28 states and 8 union territories, which are broadly demarcated on linguistic lines. Notable cities include Delhi, the capital; Mumbai, the financial capital; and Kolkata, known as the cultural capital. The landscape features four biodiversity hotspots and megadiverse land features. Significant landmarks include the Mahabodhi temple in Bodh Gaya, the rock-cut caves of Ellora and Ajanta, and the Golden Temple in Amritsar. The architecture reflects a rich legacy from various empires, including Mughal structures and colonial buildings.

India is a pluralistic, multilingual, and multi-ethnic society with a deep cultural heritage. It offers visitors a view of fascinating religions, ethnography, and diverse food traditions. The nation is home to architectural masterpieces built millennia ago that remain intact today. Cultural tolerance is traditionally viewed in its wildlife habitats, and the country hosts numerous festivals and religious sites. The blend of ancient history and modern development provides a unique experience for travelers interested in the intensity of culture and the depth of historical narratives.

As of 2020, the population was recorded at 1,326,093,247, with projections reaching over 1.4 billion by 2023. The economy is fast-growing, serving as a hub for information technology and supporting an expanding middle class. While poverty has been reduced, economic inequality remains a challenge. The nation is a nuclear-weapon state with high military expenditure. It faces unresolved disputes over Kashmir with Pakistan and China, alongside socio-economic issues such as gender inequality and rising air pollution.
