130-518: Northwestern South Asia is a geographical area in South Asia . It includes the modern-day Afghanistan , north-western India , and Pakistan . Northwestern South Asia is the site of many of the first civilisations of the world, such as the Indus Valley Civilisation . It was historically the most-conquered region of South Asia because it is the first region that invading armies coming from
260-547: A Cold War episode resulting in East Pakistan 's secession, was the most recent instance of a new nation being formed in the region. South Asia has a total area of 5.2 million sq.km (2 million sq.mi), which is 10% of the Asian continent. The population of South Asia is estimated to be 2.04 billion or about one-fourth of the world's population, making it both the most populous and the most densely populated geographical region in
390-597: A colonial economy, but also consolidating its sovereignty . British Crown rule began in 1858. The rights promised to Indians were granted slowly, but technological changes were introduced, and modern ideas of education and the public life took root. In 1947 the British Indian Empire was partitioned into two independent dominions , a Hindu-majority Dominion of India and a Muslim-majority Dominion of Pakistan , amid large-scale loss of life and an unprecedented migration. The 1971 Bangladesh Liberation War ,

Major carp become common, and chameleonfish ( Badis ), mullet ( Sicamugil ) and swamp eel ( Monopterus ) appear. In some upland lakes and tributaries of the Punjab region snow trout and mahseer are still common, but once the Indus basin reaches its lower plain
650-696: A full 5-year term in office. India has grown significantly, having slashed its rate of extreme poverty to below 20% and surpassed Pakistan's GDP per capita in the 2010s due to economic liberalisation from the 1980s onward. Bangladesh, having struggled greatly for decades due to conflict with and economic exploitation by Pakistan, is now one of the fastest-growing countries in the region, beating India in terms of GDP per capita . Afghanistan has gone through several invasions and Islamist regimes, with many of its refugees having gone to Pakistan and other parts of South Asia and bringing back cultural influences such as cricket . Religious nationalism has grown across
780-576: A ground expedition to identify an alternative source point, but detailed analysis has not yet been published. The ultimate source of the Indus is in Tibet , but there is some debate about the exact source. The traditional source of the river is the Sênggê Kanbab ( Sênggê Zangbo ) or "Lion's Mouth", a perennial spring not far from the sacred Mount Kailash , marked by a long low line of Tibetan chortens . There are several other tributaries nearby, which may form
910-678: A land mass which extends from the Himalayas into a portion of the basin under the Indian Ocean, including parts of South China and Eastern Indonesia , as well as Kunlun and Karakoram ranges, and extending up to but not including Ladakh , Kohistan , the Hindu Kush range, and Balochistan . It may be noted that geophysically the Yarlung Tsangpo River in Tibet is situated at the outside
1040-594: A large part of the region between the 4th and 7th centuries, a period that saw the construction of major temples, monasteries and universities such as the Nalanda . During this era, and through the 10th century, numerous cave monasteries and temples such as the Ajanta Caves , Badami cave temples , and Ellora Caves were built in South Asia. Islam came as a political power in the fringe of South Asia in 8th century CE when
1170-726: A longer stream than Sênggê Kanbab, but unlike the Sênggê Kanbab, are all dependent on snowmelt . The Zanskar River , which flows into the Indus in Ladakh, has a greater volume of water than the Indus itself before that point. An alternative reckoning begins the river around 300 km further upstream, at the confluence of the Sênggê Zangbo and Gar Tsangpo rivers, which drain the Nganglong Kangri and Gangdise Shan (Gang Rinpoche, Mt. Kailash) mountain ranges. The 2011 remeasurement suggested
1300-559: A major role in earlier cultures of the region, including the ancient Indus Valley Civilisation where depictions of fish were frequent. The Indus script has a commonly used fish sign, which in its various forms may simply have meant "fish", or referred to stars or gods. In the uppermost, highest part of the Indus River basin there are relatively few genera and species: Diptychus , Ptychobarbus , Schizopyge , Schizopygopsis and Schizothorax snowtrout, Triplophysa loaches, and
1430-449: A population of 2.04 billion living in South Asia, it contains a quarter (25%) of the world's population. As commonly conceptualised, the modern states of South Asia include Bangladesh , Bhutan , India , the Maldives , Nepal , Pakistan , and Sri Lanka , with Afghanistan also often included, which may otherwise be classified as part of Central Asia . South Asia borders East Asia to

Some historians chronicle the Delhi Sultanate from 1192 due to the presence and geographical claims of Mu'izz al-Din in South Asia by that time. The Delhi Sultanate covered varying parts of South Asia and was ruled by a series of dynasties: Mamluk, Khalji, Tughlaq, Sayyid, and Lodi dynasties. Muhammad bin Tughlaq came to power in 1325, launched
1690-460: A scholar of political science at Carleton University , the terms South Asia, Southwest Asia, and Central Asia are distinct, but the confusion and disagreements have arisen due to the geopolitical movement to enlarge these regions into Greater South Asia, Greater Southwest Asia , and Greater Central Asia . The frontier of Greater South Asia, states Cutler, between 2001 and 2006 has been geopolitically extended to eastern Iran and western Afghanistan in

Its estimated annual flow is around 175 km /a (5,500 m /s), making it one of the 50 largest rivers in the world in terms of average annual flow . Its left-bank tributary in Ladakh is the Zanskar River , and its left-bank tributary in the plains is the Panjnad River which is formed by the successive confluences of
1950-594: A trans- Himalayan river of South and Central Asia . The 3,180 km (1,980 mi) river rises in mountain springs northeast of Mount Kailash in Western Tibet , flows northwest through the disputed region of Kashmir , bends sharply to the left after the Nanga Parbat massif , and flows south-by-southwest through Pakistan , before emptying into the Arabian Sea near the port city of Karachi . The river has
2080-587: A war of expansion and the Delhi Sultanate reached it largest geographical reach over the South Asian region during his 26-year rule. A Sunni Sultan, Muhammad bin Tughlaq persecuted non-Muslims such as Hindus, as well as non-Sunni Muslims such as Shia and Mahdi sects. Revolts against the Delhi Sultanate sprang up in many parts of South Asia during the 14th century. In the northeast, the Bengal Sultanate became independent in 1346 CE. It remained in power through

The Ladakhis and Tibetans call the river Senge Tsangpo (སེང་གེ་གཙང་པོ།), Baltis call it Gemtsuh and Tsuh-Fo , Pashtuns call it Nilab , Sher Darya and Abbasin , while Sindhis call it Sindhu , Mehran , Purali and Samundar . The Indus River provides key water resources for Pakistan's economy – especially
2340-502: Is a fertile region and often called the "breadbasket" of the country; the damage and toll of the floods on the local agrarian economy was said to be extensive. At least 1.7 million acres (690,000 ha; 2,700 sq mi) of arable land were inundated. The flooding followed the previous year's floods, which devastated a large part of the country. Unprecedented torrential monsoon rains caused severe flooding in 16 districts of Sindh. In Pakistan currently there are six barrages on
2470-401: Is derived from the Indus River. In ancient times, "India" initially referred to those regions immediately along the east bank of the Indus, where are Punjab and Sindh now but by 300 BC, Greek writers including Herodotus and Megasthenes were applying the term to the entire subcontinent that extends much farther eastward. The lower basin of the Indus forms a natural boundary between
2600-652: Is especially critical since rainfall is meagre in the lower Indus valley. Irrigation canals were first built by the people of the Indus Valley civilisation , and later by the engineers of the Kushan Empire and the Mughal Empire . Modern irrigation was introduced by the British East India Company in 1850 – the construction of modern canals accompanied with the restoration of old canals. The British supervised
2730-658: Is joined by the Panjnad at Mithankot . Beyond this confluence, the river, at one time, was named the Satnad River ( sat = "seven", nadī = "river"), as the river now carried the waters of the Kabul River, the Indus River and the five Punjab rivers. Passing by Jamshoro , it ends in a large delta to the South of Thatta in the Sindh province of Pakistan. The Indus is one of the few rivers in

The common definition of South Asia is largely inherited from the administrative boundaries of the Indian Empire, with several exceptions. The current territories of Bangladesh , India , and Pakistan which were the core territories of
2990-408: Is prone to moderate to severe flooding. In July 2010, following abnormally heavy monsoon rains, the Indus River rose above its banks and started flooding. The rain continued for the next two months, devastating large areas of Pakistan. In Sindh , the Indus burst its banks near Sukkur on 8 August, submerging the village of Mor Khan Jatoi. In early August, the heaviest flooding moved southward along
3120-453: Is protected from river flooding by constructing around 600 km long levees . The right bank side is also leveed from Guddu barrage to Lake Manchar . In response to the levees construction, the river has been aggrading rapidly over the last 20 years leading to breaches upstream of barrages and inundation of large areas. Tarbela Dam in Pakistan is constructed on the Indus River, while

The tip of the Indian Peninsula had the highest quality pearls. Most of this region is resting on the Indian Plate , the northerly portion of the Indo-Australian Plate , separated from the rest of the Eurasian Plate . The Indian Plate includes most of South Asia, forming

Accounts of the Indus valley from the times of Alexander's campaign indicate a healthy forest cover in the region. The Mughal Emperor Babur writes of encountering rhinoceroses along its bank in his memoirs (the Baburnama ). Extensive deforestation and human interference in
3640-433: The 2010 Pakistan floods were considered "good news" for the ecosystem and population of the river delta as they brought much-needed fresh water. Any further utilization of the river basin water is not economically feasible. Vegetation and wildlife of the Indus delta are threatened by the reduced inflow of fresh water, along with extensive deforestation, industrial pollution and global warming . Damming has also isolated
3770-703: The British Empire from 1857 to 1947 also form the core territories of South Asia. The mountain countries of Nepal and Bhutan , two independent countries that were not under the British Raj but were protectorates of the Empire, and the island countries of Sri Lanka and the Maldives are generally included. By various definitions based on substantially different reasons, the British Indian Ocean Territory and
3900-688: The Ganges and Indus river basins (where up to 60% of non-monsoon irrigation comes from the glaciers ) may be faced with severe water scarcity due to both climate and socioeconomic reasons. By 2030, major Indian cities such as Mumbai , Kolkata , Cuttack , and Kochi are expected to end up with much of their territory below the tide level. In Mumbai alone, failing to adapt to this would result in damages of US$ 112–162 billion by 2050, which would nearly triple by 2070. Sea level rise in Bangladesh will displace 0.9–2.1 million people by 2050 and may force

There is an Indus site on the Amu Darya at Shortughai in northern Afghanistan, and the Indus site Alamgirpur at the Hindon River is located only 28 km (17 mi) from Delhi. As of now, over 1,052 cities and settlements have been found, mainly in
4680-588: The Kuru -Pañcāla union was the most influential. The first recorded state-level society in South Asia existed around 1000 BCE. In this period, states Samuel, emerged the Brahmana and Aranyaka layers of Vedic texts, which merged into the earliest Upanishads. These texts began to ask the meaning of a ritual, adding increasing levels of philosophical and metaphysical speculation, or "Hindu synthesis" . Increasing urbanisation of South Asia between 800 and 400 BCE, and possibly
4810-700: The Mature Harappan period, from 2600 to 1900 BCE. According to anthropologist Possehl , the Indus Valley civilisation provides a logical, if somewhat arbitrary, starting point for South Asian religions, but these links from the Indus religion to later-day South Asian traditions are subject to scholarly dispute. The Vedic period, named after the Vedic religion of the Indo-Aryans , lasted from c. 1900 to 500 BCE. The Indo-Aryans were Indo-European -speaking pastoralists who migrated into north-western India after
4940-587: The Partition of India into a Hindu-majority India and a Muslim-majority Pakistan, which resulted in significant displacement and violence and harder religious divides in the region. In 1947, the newly independent India and Pakistan had to decide how to deal with the hundreds of princely states that controlled much of the subcontinent, as well as what to do with the remaining European (non-British) colonies. A combination of referendums, military action, and negotiated accessions took place in rapid succession, leading to

The major cities of the Indus Valley Civilisation , such as Harappa and Mohenjo-daro , date back to around 3300 BC, and represent some of the largest human habitations of the ancient world. The Indus Valley Civilisation extended from across northeast Afghanistan to Pakistan and northwest India , with an upward reach from east of
5200-741: The Seleucid Empire , and possibly even farther into West Asia. The Theravada school spread south from India in the 3rd century BCE, to Sri Lanka, later to Southeast Asia. Buddhism, by the last centuries of the 1st millennium BCE, was prominent in the Himalayan region, Gandhara, Hindu Kush region, and Bactria. From about 500 BCE through about 300 CE, the Vedic-Brahmanic synthesis or "Hindu synthesis" continued. Classical Hindu and Sramanic (particularly Buddhist) ideas spread within South Asia, as well as outside South Asia. The Gupta Empire ruled over

British, French, and Portuguese colonial interests struck treaties with these rulers and established their trading ports. In northwestern South Asia, a large region was consolidated into the Sikh Empire by Ranjit Singh . After the defeat of the Nawab of Bengal and Tipu Sultan and his French allies , British traders went on to dominate much of South Asia through divide-and-rule tactics by
5980-401: The 1940s, two rival camps had emerged among independence activists: those who favored a separate nation for Indian Muslims, and those who wanted a united India . As World War II raged, over 2 million Indians fought for Britain; by the end of the war, Britain was greatly weakened, and thus decided to grant independence to the vast majority of South Asians in 1947, though this coincided with
6110-433: The Arab general Muhammad bin Qasim conquered Sindh , and Multan in southern Punjab, in modern-day Pakistan. By 962 CE, Hindu and Buddhist kingdoms in South Asia were under a wave of raids from Muslim armies from Central Asia. Among them was Mahmud of Ghazni , who raided and plundered kingdoms in north India from east of the Indus river to west of Yamuna river seventeen times between 997 and 1030. Mahmud of Ghazni raided

It consists of around 5 million cubic kilometres of material eroded from the mountains. Studies of the sediment in the modern river indicate that the Karakoram Mountains in northern Pakistan and India are the single most important source of material, with
6630-422: The Himalayas providing the next largest contribution, mostly via the large rivers of the Punjab (Jhelum, Ravi, Chenab, Beas and Sutlej). Analysis of sediments from the Arabian Sea has demonstrated that before five million years ago the Indus was not connected to these Punjab rivers which instead flowed east into the Ganga and were captured after that time. Earlier work showed that sand and silt from western Tibet

According to Saul Cohen, early colonial era strategists treated South Asia with East Asia, but in reality, the South Asia region excluding Afghanistan is a distinct geopolitical region separated from other nearby geostrategic realms, one that is geographically diverse. The region is home to a variety of geographical features, such as glaciers , rainforests , valleys , deserts , and grasslands that are typical of much larger continents. It
9620-1450: The catfish Glyptosternon reticulatum . Going downstream these are soon joined by the golden mahseer Tor putitora (alternatively T. macrolepis , although it often is regarded as a synonym of T. putitora ) and Schistura loaches. Downriver from around Thakot , Tarbela , the Kabul –Indus river confluence, Attock Khurd and Peshawar the diversity rises strongly, including many cyprinids ( Amblypharyngodon , Aspidoparia , Barilius , Chela , Cirrhinus , Crossocheilus , Cyprinion , Danio , Devario , Esomus , Garra , Labeo , Naziritor , Osteobrama , Pethia , Puntius , Rasbora , Salmophasia , Securicula and Systomus ), true loaches ( Botia and Lepidocephalus ), stone loaches ( Acanthocobitis and Nemacheilus ), ailiid catfish ( Clupisoma ), bagridae catfish ( Batasio , Mystus , Rita and Sperata ), airsac catfish ( Heteropneustes ), schilbid catfish ( Eutropiichthys ), silurid catfish ( Ompok and Wallago ), sisorid catfish ( Bagarius , Gagata , Glyptothorax and Sisor ), gouramis ( Trichogaster ), nandid leaffish ( Nandus ), snakeheads ( Channa ), spiny eel ( Macrognathus and Mastacembelus ), knifefish ( Notopterus ), glassfish ( Chanda and Parambassis ), clupeids ( Gudusia ), needlefish ( Xenentodon ) and gobies ( Glossogobius ), as well as
9750-471: The collapse of the Indus Valley Civilization. Linguistic and archaeological data show a cultural change after 1500 BCE, with the linguistic and religious data showing links with Indo-European languages and religion. By about 1200 BCE, the Vedic culture and agrarian lifestyle were established in the northwest and northern Gangetic plain of South Asia. Rudimentary state-forms appeared, of which
9880-513: The concerns of Pakistan and Bangladesh, particularly given the recurring conflicts between India and Pakistan, wherein the dominant placement of "India" as a prefix before the subcontinent might offend some political sentiments. However, in Pakistan, the term "South Asia" is considered too India-centric and was banned until 1989 after the death of Zia ul Haq . This region has also been labelled as "India" (in its classical and pre-modern sense) and " Greater India ". According to Robert M. Cutler –
10010-422: The construction of one of the most complex irrigation networks in the world. The Guddu Barrage is 1,350 m (4,430 ft) long – irrigating Sukkur , Jacobabad , Larkana and Kalat . The Sukkur Barrage serves over 20,000 km (7,700 sq mi). After Pakistan came into existence, a water control treaty signed between India and Pakistan in 1960 guaranteed that Pakistan would receive water from
10140-624: The construction of the Chashma-Jhelum link canal – linking the waters of the Indus and Jhelum rivers – extending water supplies to the regions of Bahawalpur and Multan . Pakistan constructed the Tarbela Dam near Rawalpindi – standing 2,743 metres (9,000 ft) long and 143 metres (470 ft) high, with an 80-kilometre (50 mi) long reservoir. It supports the Chashma Barrage near Dera Ismail Khan for irrigation use and flood control and
10270-497: The country most likely to be the worst-affected. In the 2017 edition of Germanwatch 's Climate Risk Index , Bangladesh and Pakistan ranked sixth and seventh respectively as the countries most affected by climate change in the period from 1996 to 2015, while India ranked fourth among the list of countries most affected by climate change in 2015. Some research suggests that South Asia as a whole would lose 2% of its GDP to climate change by 2050, while these losses would approach 9% by
10400-611: The course of the Indus. It was crossed by the invading armies of Alexander . Still, after his Macedonians conquered the west bank—joining it to the Hellenic world, they elected to retreat along the southern course of the river, ending Alexander's Asian campaign. Alexander's admiral Nearchus set out from the Indus Delta to explore the Persian Gulf , until reaching the Tigris . The Indus Valley
10530-459: The delta population of Indus River dolphins from those further upstream. Large-scale diversion of the river's water for irrigation has raised far-reaching issues. Sediment clogging from poor maintenance of canals has affected agricultural production and vegetation on numerous occasions. Irrigation itself is increasing soil salinization, reducing crop yields and in some cases rendering farmland useless for cultivation. The Tibetan Plateau contains
10660-655: The early 16th century. The state religion of the sultanate was Islam. In South India , the Hindu Vijayanagara Empire came to power in 1336 and persisted until the middle of the 16th century. It was ultimately defeated and destroyed by an alliance of the Muslim Deccan sultanates at the Battle of Talikota . About 1526, the Punjab governor Dawlat Khan Lodī reached out to the Mughal Babur and invited him to attack
10790-682: The early 19th century. The region experienced significant de-industrialisation in its first few decades of British rule. Control over the subcontinent was then transferred to the British government after the Indian Rebellion of 1857 , with the British cracking down to some extent afterwards. An increase of famines and extreme poverty characterised the colonial period, though railways built with British technology eventually provided crucial famine relief by increasing food distribution throughout India. Millions of South Asians began to migrate throughout
10920-455: The ecology of the Shivalik Hills has led to a marked deterioration in vegetation and growing conditions. The Indus valley regions are arid with poor vegetation. Agriculture is sustained largely due to irrigation works. The Indus river and its watershed have a rich biodiversity. It is home to around 25 amphibian species. The Indus river dolphin ( Platanista indicus minor ) is found only in
11050-623: The end of the century under the most intense climate change scenario. Ethnolinguistically , Northern South Asia is predominantly Indo-Aryan , along with Iranic populations in Afghanistan and Balochistan , and diverse linguistic communities near the Himalayas. Its borders have been heavily contested (primarily between India and its neighbours Pakistan and China , as well as separatist movements in Northeast India.) This tension in
11180-528: The five Punjab rivers, namely the Chenab , Jhelum , Ravi , Beas , and Sutlej rivers. Its principal right-bank tributaries are the Shyok , Gilgit , Kabul , Kurram , and Gomal rivers. Beginning in a mountain spring and fed with glaciers and rivers in the Himalayan , Karakoram , and Hindu Kush ranges, the river supports the ecosystems of temperate forests , plains, and arid countryside. The northern part of
11310-517: The flows of the Indus could be severely, severely affected by glacier melt as a consequence of climate change ," and reduced by perhaps as much as 50 per cent. "Now what does that mean to a population that lives in a desert [where], without the river, there would be no life? I don't know the answer to that question," he says. "But we need to be concerned about that. Deeply, deeply concerned." U.S. diplomat Richard Holbrooke said, shortly before he died in 2010, that he believed that falling water levels in
11440-501: The former group is absent and the latter are rare. Many of the species of the middle sections of the Indus basin are also present in the lower. Notable examples of genera that are present in the lower plain but generally not elsewhere in the Indus River basin are the Aphanius pupfish, Aplocheilus killifish, palla fish ( Tenualosa ilisha ), catla ( Labeo catla ), rohu ( Labeo rohita ) and Cirrhinus mrigala . The lowermost part of
11570-413: The future as the monsoon pattern intensifies. Across Asia as a whole, 100-year extremes in vapour transport (directly related to extreme precipitation) would become 2.6 times more frequent under 1.5 °C (2.7 °F) of global warming, yet 3.9 and 7.5 times more frequent under 2 °C (3.6 °F) and 3 °C (5.4 °F). In parts of South Asia, they could become up to 15 times more frequent. At
11700-529: The general region of the Ghaggar-Hakra River and its tributaries. Among the settlements were the major urban centres of Harappa and Mohenjo-daro, as well as Lothal , Dholavira , Ganeriwala , and Rakhigarhi . Only 40 Indus Valley sites have been discovered on the Indus and its tributaries. However, it is notable that majority of the Indus script seals and inscribed objects discovered were found at sites along
11830-409: The lowest-emission climate change scenarios . Under the high-emission scenario, 40 million people (nearly 2% of the South Asian population) may be driven to internal migration by 2050 due to climate change. India is estimated to have the world's highest social cost of carbon - meaning that it experiences the greatest impact from greenhouse gas emissions . Other estimates describe Bangladesh as
11960-480: The mesolithic sites as evidenced by the rock paintings of Bhimbetka rock shelters dating to a period of 30,000 BCE or older, as well as neolithic times. The Indus Valley civilisation , which spread and flourished in the northwestern part of South Asia from c. 3300 to 1300 BCE in present-day Pakistan , North India , and Afghanistan , was the first major civilisation in South Asia. A sophisticated and technologically advanced urban culture developed in
12090-501: The north, the Hindu Kush in the west, and the Arakanese in the east, and which extends southward into the Indian Ocean with the Arabian Sea to the southwest and the Bay of Bengal to the southeast. The terms " Indian subcontinent " and "South Asia" are sometimes used interchangeably. The Indian subcontinent is largely a geological term referring to the land mass that drifted northeastwards from ancient Gondwana , colliding with
12220-553: The north-Asian bitter cold winds, the temperatures are considerably moderate in the plains down below. For the most part, the climate of the region is called the monsoon climate, which keeps the region humid during summer and dry during winter, and favours the cultivation of jute , tea, rice, and various vegetables in this region. South Asia is largely divided into four broad climate zones: Maximum relative humidity of over 80% has been recorded in Khasi and Jaintia Hills and Sri Lanka, while
12350-471: The northeast, Central Asia to the northwest, West Asia to the west and Southeast Asia to the east. Apart from Southeast Asia, Maritime South Asia is the only subregion of Asia that lies partly within the Southern Hemisphere . The British Indian Ocean Territory and two out of 26 atolls of the Maldives in South Asia lie entirely within the Southern Hemisphere . Topographically, it is dominated by
12480-596: The northwest, with the Dravidian languages being supplanted in the northern and western regions. By 400 BCE , stratification and exclusion by caste had emerged within Hinduism , and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity. In the early medieval era, Christianity , Islam , Judaism , and Zoroastrianism became established on South Asia's southern and western coasts. Muslim armies from Central Asia intermittently overran
12610-570: The northwestern and Indo-Gangetic Plain regions of South Asia. Several regions of South Asia were largely under Hindu kings such as those of the Vijayanagara Empire and the Kingdom of Mewar . Parts of modern Telangana and Andhra Pradesh were under local Muslim rulers, namely those of the Deccan sultanates. The Mughal Empire continued its wars of expansion after Babur's death. With the fall of
12740-469: The plains of northern India, eventually founding the Delhi Sultanate in the 13th century, and drawing the region into the cosmopolitan networks of medieval Islam . The Islamic Mughal Empire , in 1526, ushered in two centuries of relative peace, leaving a legacy of luminous architecture. Gradually expanding rule of the British East India Company followed, turning most of South Asia into
12870-501: The plural, and most often used in the generic sense of "river". In the Rigveda, notably in the later hymns, the meaning of the word is narrowed to refer to the Indus river in particular; for example, in the list of rivers mentioned in the hymn of Nadistuti sukta . The Rigvedic hymns apply a feminine gender to all the rivers mentioned therein, except for the Brahmaputra . The word "India"
13000-548: The political integration of the vast majority of India and Pakistan within a few years. India and Pakistan clashed several times in the decades after Independence, with disputes over Kashmir playing a significant role. In 1971, the eastern half of Pakistan seceded with help from India and became the People's Republic of Bangladesh after the traumatic Bangladesh Liberation War . This, along with India and Pakistan gaining nuclear weapons soon afterwards, increased tensions between
13130-474: The region has contributed to difficulties in sharing river waters among Northern South Asian countries; climate change is projected to exacerbate the issue. Dominated by the Indo-Gangetic Plain , the region is home to about half a billion people and is the poorest South Asian subregion. Indus River The Indus ( / ˈ ɪ n d ə s / IN -dəs ) is a transboundary river of Asia and
13260-405: The region is defined. South Asia's northern, eastern, and western boundaries vary based on definitions used, while the Indian Ocean is the southern periphery. Most of this region rests on the Indian Plate and is isolated from the rest of Asia by mountain barriers. Much of the region consists of a peninsula in south-central Asia, rather resembling a diamond which is delineated by the Himalayas on
13390-546: The region saw most Indian Muslims in Northwestern South Asia become part of the new nation of Pakistan during the 1947 Partition of India . The 20th and 21st centuries saw Afghanistan invaded several times, with the Taliban having intermittently been in charge of the country. South Asia South Asia is the southern subregion of Asia , which is defined in both geographical and ethnic - cultural terms. With
13520-497: The region was largely Hindu and Buddhist, and was home to hotbeds of Buddhist activity such as Gandhara . Greek invasions of Northwestern South Asia over 2,000 years ago produced the Indo-Greek Kingdom and a syncretised culture. Buddhism was prominent in this region, and traveled from here to China through Central Asia . Afghanistan was conquered by Muslims starting in the 7th century after Arabs had crossed Persia. Sindh
13650-653: The region, with persecution causing millions of Hindus and Christians to flee Pakistan and Bangladesh, and Hindu nationalism having grown in India with the election of the Bharatiya Janata Party in 2014. A recent phenomenon has been that of India and China fighting on their border , as well as vying for dominance of South Asia , with China partnering with Pakistan and using its superior economy to attract countries surrounding India, while America and other countries have strengthened ties with India to counter China in
13780-420: The relocation of up to one third of power plants by 2030. Food security will become more uneven, and some South Asian countries could experience significant social impacts from global food price volatility. Infectious diarrhoea mortality and dengue fever incidence is also likely to increase across South Asia. Parts of South Asia would also reach "critical health thresholds" for heat stress under all but
13910-412: The river and its delta are home to freshwater fish, but also several brackish and marine species. This includes pomfret and prawns . The large delta has been recognized by conservationists as an important ecological region. Here, the river turns into many marshes, streams and creeks and meets the sea at shallow levels. Palla fish ( Tenualosa ilisha ) of the river is a delicacy for people living along
14040-495: The river varies in different sources. The length used in this article is 3,180 km (1,980 mi), taken from the Himalayan Climate and Water Atlas (2015). Historically, the 1909 The Imperial Gazetteer of India gave it as "just over 1,800 miles". A shorter figure of 2,880 km (1,790 mi) has been widely used in modern sources, as has the one of 3,180 km (1,980 mi). The modern Encyclopedia Britannica
14170-664: The river, c. 515 BC . Etymologically, English language word "Indus" comes from Late Latin Indus (1598), specifically a use of classical Latin Indus (inhabitant of India, Indian) from ancient Greek Ἰνδός "inhabitant of India, Indian, the River Indus" from Achaemenian Old Persian "hindu," denoting an eastern province of the Achaemenid empire ( Persian language hind India), and Avestan hiṇdu , həṇdu "river," (natural) frontier; with same Proto Indo-Iranian language -root as Sanskrit sindhu (river), specifically
14300-484: The river. The population of fish in the river is moderately high, with Sukkur , Thatta , and Kotri being the major fishing centres – all in the lower Sindh course. As a result, damming and irrigation have made fish farming an important economic activity. The Indus is the most important supplier of water resources to the Punjab and Sindh plains – it forms the backbone of agriculture and food production in Pakistan. The river
14430-470: The same time, up to two-thirds of glacier ice in the Hindu Kush region may melt by 2100 under high warming, and these glaciers feed the water basin of over 220 million people. As glacier meltwater flow diminishes after 2050, Hydropower generation would become less predictable and reliable, while agriculture would become more reliant on the intensified monsoon than ever before. Around 2050, people living in
14560-474: The source was a small lake northeast of Mount Kailash, rather than either of the two points previously used. The Indus then flows northwest through Ladakh (Indian-administered Kashmir) and Baltistan and Gilgit (Pakistan-administered Kashmir), just south of the Karakoram range. The Shyok , Shigar and Gilgit rivers carry glacial waters into the main river. It gradually bends to the south and descends into
14690-416: The spread of urban diseases, contributed to the rise of ascetic movements and of new ideas which challenged the orthodox Brahmanism . These ideas led to Sramana movements, of which Mahavira ( c. 549 –477 BCE), proponent of Jainism , and Buddha ( c. 563 – c. 483 ), founder of Buddhism , was the most prominent icons. The Greek army led by Alexander the Great stayed in
14820-549: The surface. In November 2011, satellite images showed that the Indus river had re-entered India and was feeding the Great Rann of Kutch , Little Rann of Kutch and a lake near Ahmedabad known as Nal Sarovar . Heavy rains had left the river basin along with the Lake Manchar , Lake Hemal and Kalri Lake (all in modern-day Pakistan) inundated. This happened two centuries after the Indus river shifted its course westwards following
14950-499: The term Indian subcontinent began in the British Empire, and has been a term particularly common in its successors. South Asia as the preferred term is particularly common when scholars or officials seek to differentiate this region from East Asia. According to historians Sugata Bose and Ayesha Jalal , the Indian subcontinent has come to be known as South Asia "in more recent and neutral parlance." This "neutral" notion refers to
15080-513: The treasuries but retracted each time, only extending Islamic rule into western Punjab. The wave of raids on north Indian and western Indian kingdoms by Muslim warlords continued after Mahmud of Ghazni, plundering and looting these kingdoms. The raids did not establish or extend permanent boundaries of their Islamic kingdoms. The Ghurid Sultan Mu'izz al-Din Muhammad began a systematic war of expansion into North India in 1173. He sought to carve out
15210-584: The two countries. The Cold War decades also contributed to the divide , as Pakistan aligned with the West and India with the Soviet Union ; other factors include the time period after the 1962 Sino-Indian War , which saw India and China move apart while Pakistan and China built closer relations. Pakistan has been beset with terrorism , economic issues , and military dominance of its government since Independence, with none of its Prime Ministers having completed
15340-466: The west had to cross to enter the Indian subcontinent ; notable conquests include the Indian campaign of Alexander the Great in the fourth century BCE and several Muslim invasions from the 8th century CE to the 18th century. Because of these many invasions, Northwestern South Asia has significant influences from various sources outside of South Asia, mainly from the Muslim world . Prior to Islamic influence,
15470-534: The west, and in the north to northeastern Iran, northern Afghanistan, and southern Uzbekistan . Identification with a South Asian identity was found to be significantly low among respondents in an older two-year survey across Bangladesh, India, Nepal, Pakistan, and Sri Lanka. The history of core South Asia begins with evidence of human activity of Homo sapiens , as long as 75,000 years ago, or with earlier hominids including Homo erectus from about 500,000 years ago. The earliest prehistoric culture have roots in
15600-472: The west. Originally, the delta used to receive almost all of the water from the Indus River, which has an annual flow of approximately 180 billion cubic metres (240 × 10 ^ cu yd), and is accompanied by 400 million tonnes (390 × 10 ^ long tons) of silt. Since the 1940s, dams, barrages and irrigation works have been constructed on the river. The Indus Basin Irrigation System
15730-547: The world , impelled by the economic/ labour needs and opportunities presented by the British Empire. The introduction of Western political thought inspired a growing Indian intellectual movement, and so by the 20th century, British rule began to be challenged by the Indian National Congress , which sought full independence under the leadership of Mahatma Gandhi . Britain, under pressure from Indian freedom fighters, increasingly gave self-rule to British India. By
15860-453: The world to exhibit a tidal bore . The Indus system is largely fed by the snow and glaciers of the Himalayas , Karakoram and the Hindu Kush ranges. The flow of the river is also determined by the seasons – it diminishes greatly in the winter while flooding its banks in the monsoon months from July to September. There is also evidence of a steady shift in the course of the river since prehistoric times – it deviated westwards from flowing into
15990-635: The world's third-largest store of ice. Qin Dahe, the former head of the China Meteorological Administration, said the recent fast pace of melting and warmer temperatures will be good for agriculture and tourism in the short term, but issued a strong warning: Temperatures are rising four times faster than elsewhere in China, and the Tibetan glaciers are retreating at a higher speed than in any other part of
16120-412: The world. In 2022, South Asia had the world's largest populations of Hindus , Muslims , Sikhs , Jains, and Zoroastrians. South Asia alone accounts for 90.47% of Hindus, 95.5% of Sikhs, and 31% of Muslims worldwide, as well as 35 million Christians and 25 million Buddhists. The South Asian Association for Regional Cooperation (SAARC) is an economic cooperation organisation in the region which
16250-460: The world... In the short term, this will cause lakes to expand and bring floods and mudflows... In the long run, the glaciers are vital lifelines of the Indus River. Once they vanish, water supplies in Pakistan will be in peril. "There is insufficient data to say what will happen to the Indus," says David Grey, the World Bank's senior water advisor in South Asia. "But we all have very nasty fears that
16380-439: Was established in 1985 and includes all the nations comprising South Asia. The geographical extent is not clear cut as systemic and foreign policy orientations of its constituents are quite asymmetrical. Beyond the core territories of the Indian Empire (territories of the British Empire which were under the system of British Raj), there is a high degree of variation as to which other countries are included in South Asia. There
16510-454: Was later dominated by the Mauryan and Kushan Empires , Indo-Greek Kingdoms , Indo-Scythians and Hepthalites . Over several centuries Muslim armies of Muhammad ibn al-Qasim , Mahmud of Ghazni , Muhammad of Ghor , Timur and Babur crossed the river to invade Sindh and Punjab , providing a gateway to the Indian subcontinent. Indus is an antecedent river , meaning that it existed before
16640-419: Was originally published in 1999 with the shorter measurement, but was updated in 2015 to use the longer measurement. Both lengths are commonly found in modern publications; in some cases, both measurements can be found within the same work. An extended figure of circa 3,600 km (2,200 mi) was announced by a Chinese research group in 2011, based on a comprehensive remeasurement from satellite imagery, and
16770-550: Was reaching the Arabian Sea by 45 million years ago, implying the existence of an ancient Indus River by that time. The delta of this proto-Indus river has subsequently been found in the Katawaz Basin , on the Afghan-Pakistan border . In the Nanga Parbat region, the massive amounts of erosion due to the Indus river following the capture and rerouting through that area are thought to bring middle and lower crustal rocks to
16900-539: Was the first region in the subcontinent to be conquered by Muslims, falling to the Umayyad Caliphate in the first Islamic century. During the subsequent Muslim invasions of the region, the religion of Sikhism was born, producing a warrior class with affinities to both Hindus and Muslims that was persecuted by and that fought against the invaders. Buddhism vanished from the region during Muslim rule, prompted by persecution and conversions. The end of colonial rule in
