The following outline is provided as an overview of and topical guide to India:
Republic of India – the seventh-largest country by area, located on the Indian subcontinent in South Asia. India was home to the ancient Indus Valley Civilisation, and is the birthplace of four major world religions: Hinduism, Sikhism, Buddhism, Jainism. It is also home to followers of Islam, Christianity, Judaism, Zoroastrianism.. From 1857 to 1947, India was under British rule. India became an independent nation in 1947 after a struggle for independence, and underwent a violent partition, which split the erstwhile British Raj into the independent countries of India and Pakistan, (with East Pakistan rebelling against Pakistan in 1971 to form Bangladesh). As of June 2025, India is the most populous country in the world, with a population exceeding 1.4 billion. It is recognised as the world's largest democracy by population and has emerged as the fourth-largest economy globally.

Geography of India
India covers an area of 3,287,263 sq. km, extending from the snow-covered Himalayas in the north to the tropical rainforests in the south. Bounded by the Great Himalayas in the north, the country stretches southward and tapers into the Indian Ocean at the Tropic of Cancer, flanked by the Bay of Bengal to the east and the Arabian Sea to the west.
Lying entirely in the Northern Hemisphere, IndiaâÂÂs mainland spans latitudes 8ð4' to 37ð6' N and longitudes 68ð7' to 97ð25' E. It measures about 3,214 km from north to south and approximately 2,933 km from east to west. The land frontier is about 15,200 km long, and the total coastline; including the mainland, Lakshadweep, and Andaman & Nicobar Islands is 7,516.6 km.
India shares borders with Pakistan to the northwest; China, Bhutan, and Nepal to the north; Myanmar to the east; and Bangladesh to the east of West Bengal. Sri Lanka lies to the south, separated by the Palk Strait and the Gulf of Mannar.

Physical divisions of India
Based on these macro variations, India can be divided into the following physiographic divisions:
- The Northern and North-eastern Mountains - The North and Northeastern Mountains consist of the Himalayas and the Northeastern hills. Some important ranges are Great Himalayan Range(includes Greater Himalayas, Himadri; the Lesser Himalayas, Himachal and the Outer Himalayas, Shiwalik), Karakoram ranges and the northeast mountain ranges.
- The Northern Plain - Located south of the Himalayas, the northern plains are formed by the deposition of sediments from Himalayan rivers Indus, Ganga and Brahmaputra. It is further divided intro Babhar, Tarai, Alluvial plains further dividing into Khadar & Bhangar.
- The Peninsular Plateau - Rising from the height of 150 m above the river plains up to an elevation of 600-900 m is the irregular triangle known as the Peninsular plateau. It is one of the oldest and the most stable landmass of India. Delhi ridge in the northwest, (extension of Aravalis), the Rajmahal hills in the east, Gir range in the west and the Cardamom hills in the south constitute the outer extent of the Peninsular plateau. However, an extension of this is also seen in the northeast, in the form of Shillong and Karbi-Anglong plateau. It is made up of series of patland plateaus such as the Hazaribagh plateau, the Palamu plateau, the Ranchi plateau, the Malwa plateau, the Coimbatore plateau and the Karnataka plateau, etc. On the basis of the prominent relief features, the Peninsular plateau can be divided into three broad groups: (i) The Deccan Plateau (ii) The Central Highlands (iii) The Northeastern Plateau.
- The Indian Desert - To the northwest of the Aravali hills lies the Great Indian desert also known as Thar Desert.
- The Coastal Plains - It is broadly classified into Eastern coastal plains and Western coastal plains
- The Islands - There are two major island groups in India; one in the Bay of Bengal named Andaman & Nicobar Islands and the other in the Arabian Sea named Lakshadweep.
