The Republic of India

India, officially the Republic of India ( Hindi: ), is a country in South Asia. It is the seventh-largest country by 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 southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, intermittently, sometime between 60,000 and 80,000 years ago, tiny groups of them began to enter the north-west of the Indian subcontinent. It seems likely that initially they came by way of the coast. ... it is virtually certain that there were ''Homo sapiens'' in the subcontinent 55,000 years ago, even though the earliest fossils that have been found of them date to only about 30,000 years before the present.", "Scholars estimate that the first successful expansion of the ''Homo sapiens'' range beyond Africa and across the Arabian Peninsula occurred from as early as 80,000 years ago to as late as 40,000 years ago, although there may have been prior unsuccessful emigrations. Some of their descendants extended the human range ever further in each generation, spreading into each habitable land they encountered. One human channel was along the warm and productive coastal lands of the Persian Gulf and northern Indian Ocean. Eventually, various bands entered India between 75,000 years ago and 35,000 years ago."
Their long occupation, initially in varying forms of isolation as hunter-gatherers, has made the region highly diverse, second only to Africa in human genetic diversity. Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE.(a) ;

By , an archaic form of Sanskrit, an Indo-European language, had diffused into India from the northwest.(a)

(c) , "In Punjab, a dry region with grasslands watered by five rivers (hence ‘panch’ and ‘ab’) draining the western Himalayas, one prehistoric culture left no material remains, but some of its ritual texts were preserved orally over the millennia. The culture is called Aryan, and evidence in its texts indicates that it spread slowly south-east, following the course of the Yamuna and Ganga Rivers. Its elite called itself Arya (pure) and distinguished themselves sharply from others. Aryans led kin groups organized as nomadic horse-herding tribes. Their ritual texts are called Vedas, composed in Sanskrit. Vedic Sanskrit is recorded only in hymns that were part of Vedic rituals to Aryan gods. To be Aryan apparently meant to belong to the elite among pastoral tribes. Texts that record Aryan culture are not precisely datable, but they seem to begin around 1200 BCE with four collections of Vedic hymns (Rg, Sama, Yajur, and Artharva)."

(d) , "Although the collapse of the Indus valley civilization is no longer believed to have been due to an ‘Aryan invasion’ it is widely thought that, at roughly the same time, or perhaps a few centuries later, new Indo-Aryan-speaking people and influences began to enter the subcontinent from the north-west. Detailed evidence is lacking. Nevertheless, a predecessor of the language that would eventually be called Sanskrit was probably introduced into the north-west sometime between 3,900 and 3,000 years ago. This language was related to one then spoken in eastern Iran; and both of these languages belonged to the Indo-European language family. ... It seems likely that various small-scale migrations were involved in the gradual introduction of the predecessor language and associated cultural characteristics. However, there may not have been a tight relationship between movements of people on the one hand, and changes in language and culture on the other. Moreover, the process whereby a dynamic new force gradually arose—a people with a distinct ideology who eventually seem to have referred to themselves as ‘Arya’—was certainly two-way. That is, it involved a blending of new features which came from outside with other features—probably including some surviving Harappan influences—that were already present. Anyhow, it would be quite a few centuries before Sanskrit was written down. And the hymns and stories of the Arya people—especially the Vedas and the later Mahabharata and Ramayana epics—are poor guides as to historical events. Of course, the emerging Arya were to have a huge impact on the history of the subcontinent. Nevertheless, little is known about their early presence.";
(e) , "The expansion of Aryan culture is supposed to have begun around 1500 BCE. It should not be thought that this Aryan emergence (though it implies some migration) necessarily meant either a sudden invasion of new peoples, or a complete break with earlier traditions. It comprises a set of cultural ideas and practices, upheld by a Sanskrit-speaking elite, or Aryans. The features of this society are recorded in the Vedas." Its evidence today is found in the hymns of the '' Rigveda''. Preserved by a resolutely vigilant oral tradition, the ''Rigveda'' records the dawning of Hinduism in India.(a) ;

In 1947 the British Indian Empire was partitioned into two independent dominions,: "The partition of South Asia that produced India and West and East Pakistan resulted from years of bitter negotiations and recriminations ... The departing British also decreed that the hundreds of princes, who ruled one-third of the subcontinent and a quarter of its population, became legally independent, their status to be settled later. Geographical location, personal and popular sentiment, and substantial pressure and incentives from the new governments led almost all princes eventually to merge their domains into either Pakistan or India. ... Each new government asserted its exclusive sovereignty within its borders, realigning all territories, animals, plants, minerals, and all other natural and human-made resources as either Pakistani or Indian property, to be used for its national development... Simultaneously, the central civil and military services and judiciary split roughly along religious 'communal' lines, even as they divided movable government assets according to a negotiated formula: 22.7 percent for Pakistan and 77.3 percent for India." a Hindu-majority Dominion of India and a Muslim-majority Dominion of Pakistan, amid large-scale loss of life and an unprecedented migration.

India has been a federal republic since 1950, governed through a democratic parliamentary system. It is a pluralistic, multilingual and multi-ethnic society. India's population grew from 361 million in 1951 to 1.4  billion in 2022.
During the same time, its nominal per capita income increased from US$64 annually to US$1,498, and its literacy rate from 16.6% to 74%. From being a comparatively destitute country in 1951,
India has become a fast-growing major economy and a hub for information technology services, with an expanding middle class. It has a space programme which includes several planned or completed extraterrestrial missions. Indian movies, music, and spiritual teachings play an increasing role in global culture.
India has substantially reduced its rate of poverty, though at the cost of increasing economic inequality.
India is a nuclear-weapon state, which ranks high in military expenditure. It has disputes over Kashmir with its neighbours, Pakistan and China, unresolved since the mid-20th century.(a) ;

India's land is megadiverse, with four biodiversity hotspots. Its forest cover comprises 21.7% of its area. India's wildlife, which has traditionally been viewed with tolerance in India's culture, is supported among these forests, and elsewhere, in protected habitats.

Etymology

According to the '' Oxford English Dictionary'' (third edition 2009), the name "India" is derived from the Classical Latin ''India'', a reference to South Asia and an uncertain region to its east; and in turn derived successively from: Hellenistic Greek ''India'' ('' Ἰνδία''); ancient Greek ''Indos'' ('' Ἰνδός''); Old Persian ''Hindush'', an eastern province of the Achaemenid Empire; and ultimately its cognate, the Sanskrit ''Sindhu'', or "river," specifically the Indus River and, by implication, its well-settled southern basin. The ancient Greeks referred to the Indians as ''Indoi'' ('), which translates as "The people of the Indus".

The term '' Bharat'' (; ), mentioned in both Indian epic poetry and the Constitution of India, is used in its variations by many Indian languages. A modern rendering of the historical name ''Bharatavarsha'', which applied originally to North India, ''Bharat'' gained increased currency from the mid-19th century as a native name for India.

'' Hindustan'' () is a Middle Persian name for India, introduced during the Mughal Empire and used widely since. Its meaning has varied, referring to a region encompassing present-day northern India and Pakistan or to India in its near entirety.

History

Ancient India

By 55,000 years ago, the first modern humans, or '' Homo sapiens'', had arrived on the Indian subcontinent from Africa, where they had earlier evolved. The earliest known modern human remains in South Asia date to about 30,000 years ago. After , evidence for domestication of food crops and animals, construction of permanent structures, and storage of agricultural surplus appeared in Mehrgarh and other sites in what is now Balochistan, Pakistan. These gradually developed into the Indus Valley Civilisation, the first urban culture in South Asia, which flourished during in what is now Pakistan and western India. Centred around cities such as Mohenjo-daro
