India has been a secular federal republic since 1950, governed in a democratic parliamentary system. It is a pluralistic, multilingual and multi-ethnic society. India’s population grew from 361 million in 1951 to 1,211 million in 2011. 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, a hub for information technology services, with an expanding middle class. It has a space program 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 weapons state, which ranks high in military expenditure.
It has disputes over Kashmir with its neighbors, Pakistan and China, unresolved since the mid-20th century. Among the socio-economic challenges India faces are gender inequality, child malnutrition, and rising levels of air pollution. India’s land is megadiverse, with four biodiversity hot-spots. Its forest cover comprises 21.4% 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.
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 6500 BCE, 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. These gradually developed into the Indus Valley Civilization, the first urban culture in South Asia, which flourished during 2500–1900 BCE in what is now Pakistan and western India. Centered around cities such as Mohenjo-daro, Harappa, Dholavira, and Kalibangan, and relying on varied forms of subsistence, the civilisation engaged robustly in crafts production and wide-ranging trade.
During the period 2000–500 BCE, many regions of the subcontinent transitioned from the Chalcolithic cultures to the Iron Age ones. The Vedas, the oldest scriptures associated with Hinduism, were composed during this period, and historians have analysed these to posit a Vedic culture in the Punjab region and the upper Gangetic Plain. Most historians also consider this period to have encompassed several waves of Indo-Aryan migration into the subcontinent from the north-west. The caste system, which created a hierarchy of priests, warriors, and free peasants, but which excluded indigenous peoples by labeling their occupations impure, arose during this period. On the Deccan Plateau, archaeological evidence from this period suggests the existence of a chiefdom stage of political organisation. In South India, a progression to sedentary life is indicated by the large number of megalithic monuments dating from this period, as well as by nearby traces of agriculture, irrigation tanks, and craft traditions.
