The Indus Valley Civilisation

civilisation in the northwestern regions of South Asia, lasting from 3300 BCE to 1300 BCE, and in its mature form 2600 BCE to 1900 BCE.[2][a] Together with ancient Egypt and Mesopotamia, it was one of three early civilisations of the Near East and South Asia, and of the three, the most widespread, its sites spanning an area from much of Pakistan, to northeast Afghanistan, and northwestern India.[3][b] The civilisation flourished both in the alluvial plain of the Indus River, which flows through the length of Pakistan, and along a system of perennial monsoon-fed rivers that once coursed in the vicinity of the Ghaggar-Hakra, a seasonal river in northwest India and eastern Pakistan.[2][4]

The term Harappan is sometimes applied to the Indus civilisation after its type site Harappa, the first to be excavated early in the 20th century in what was then the Punjab province of British India and is now Punjab, Pakistan.[5][c] The discovery of Harappa and soon afterwards Mohenjo-daro was the culmination of work that had begun after the founding of the Archaeological Survey of India in the British Raj in 1861.[6] There were earlier and later cultures called Early Harappan and Late Harappan in the same area. The early Harappan cultures were populated from Neolithic cultures, the earliest and best-known of which is named after Mehrgarh, in Balochistan, Pakistan.[7][8] Harappan civilisation is sometimes called Mature Harappan to distinguish it from the earlier cultures.

The cities of the ancient Indus were noted for their

baked brick houses, elaborate drainage systems, water supply systems, clusters of large non-residential buildings, and techniques of handicraft and metallurgy.[d] Mohenjo-daro and Harappa very likely grew to contain between 30,000 and 60,000 individuals,[10] and the civilisation may have contained between one and five million individuals during its florescence.[11] A gradual drying of the region during the 3rd millennium BCE may have been the initial stimulus for its urbanisation. Eventually it also reduced the water supply enough to cause the civilisation's demise and to disperse its population to the east.[e]

Although over a thousand Mature Harappan sites have been reported and nearly a hundred excavated,

Ganeriwala in the Cholistan Desert, Dholavira in western Gujarat (declared a UNESCO World Heritage Site in 2021 as "Dholavira: A Harappan City"), and Rakhigarhi in Haryana.[13][h] The Harappan language is not directly attested, and its affiliations are uncertain, as the Indus script has remained undeciphered.[14] A relationship with the Dravidian or Elamo-Dravidian language family is favoured by a section of scholars.[15][16]

Etymology

The Indus civilisation is named after the Indus river system in whose alluvial plains the early sites of the civilisation were identified and excavated.[17][i]

Following a tradition in archaeology, the civilisation is sometimes referred to as the Harappan, after its type site, Harappa, the first site to be excavated in the 1920s; this is notably true of usage employed by the Archaeological Survey of India after India's independence in 1947.[18][j]

The term "Ghaggar-Hakra" figures prominently in modern labels applied to the Indus civilisation on account of a good number of sites having been found along the Ghaggar-Hakra River in northwest India and eastern Pakistan.[19] The terms "Indus-Sarasvati Civilisation" and "Sindhu-Saraswati Civilisation" have also been employed in the literature after a posited identification of the Ghaggar-Hakra with the river Sarasvati described in the early chapters of Rigveda, a collection of hymns in archaic Sanskrit composed in the second-millennium BCE.[20][21]

Recent geophysical research suggests that unlike the Sarasvati, described in the Rigveda as a snow-fed river, the Ghaggar-Hakra was a system of perennial monsoon-fed rivers, which became seasonal around the time that the civilisation diminished, approximately 4,000 years ago.[4][k]

Extent

Major sites and extent of the Indus Valley Civilisation

The Indus Valley Civilisation was roughly contemporary with the other riverine civilisations of the ancient world: Ancient Egypt along the Nile, Mesopotamia in the lands watered by the Euphrates and the Tigris, and China in the drainage basin of the Yellow River and the Yangtze. By the time of its mature phase, the civilisation had spread over an area larger than the others, which included a core of 1,500 kilometres (900 mi) up the alluvial plain of the Indus and its tributaries. In addition, there was a region with disparate flora, fauna, and habitats, up to ten times as large, which had been shaped culturally and economically by the Indus.[22][l]

Around 6500 BCE, agriculture emerged in Balochistan, on the margins of the Indus alluvium.[23][m][24][n] In the following millennia, settled life made inroads into the Indus plains, setting the stage for the growth of rural and urban settlements.[25][o] The more organized sedentary life, in turn, led to a net increase in the birth rate.[23][p] The large urban centres of Mohenjo-daro and Harappa very likely grew to containing between 30,000 and 60,000 individuals, and during the civilisation's florescence, the population of the subcontinent grew to between 4–6 million people.[23][q] During this period the death rate increased, as the close living conditions of humans and domesticated animals led to an increase in contagious diseases.[24][r] According to one estimate, the population of the Indus civilisation at its peak may have been between one and five million.[26][s]

During its height the civilisation extended from Balochistan in the west to western

Oxus River at Shortugai in Afghanistan which is the northernmost site of the Indus Valley Civilisation,[29] in the Gomal River valley in northwestern Pakistan,[30] at Manda, Jammu on the Beas River near Jammu,[31] and at Alamgirpur on the Hindon River, only 28 km (17 mi) from Delhi.[32] The southernmost site of the Indus Valley Civilisation is Daimabad in Maharashtra. Indus Valley sites have been found most often on rivers, but also on the ancient seacoast,[33] for example, Balakot (Kot Bala),[34] and on islands, for example, Dholavira.[35]

Discovery and history of excavation

Alexander Cunningham, the first director general of the Archaeological Survey of India (ASI), interpreted a Harappan stamp seal in 1875.
R. D. Banerji, an officer of the ASI, visited Mohenjo-daro in 1919–1920, and again in 1922–1923, postulating the site's far-off antiquity.
John Marshall, the director-general of the ASI from 1902 to 1928, who oversaw the excavations in Harappa and Mohenjo-daro, shown in a 1906 photograph

"Three other scholars whose names I cannot pass over in silence, are the late Mr. R. D. Banerji, to whom belongs the credit of having discovered, if not Mohenjo-daro itself, at any rate its high antiquity, and his immediate successors in the task of excavation, Messrs. M.S. Vats and K.N. Dikshit. ... no one probably except myself can fully appreciate the difficulties and hardships which they had to face in the three first seasons at Mohenjo-daro."

The first modern accounts of the ruins of the Indus civilisation are those of Charles Masson, a deserter from the East India Company's army.[37] In 1829, Masson traveled through the princely state of Punjab, gathering useful intelligence for the Company in return for a promise of clemency.[37] An aspect of this arrangement was the additional requirement to hand over to the Company any historical artifacts acquired during his travels. Masson, who had versed himself in the classics, especially in the military campaigns of Alexander the Great, chose for his wanderings some of the same towns that had featured in Alexander's campaigns, and whose archaeological sites had been noted by the campaign's chroniclers.[37] Masson's major archaeological discovery in the Punjab was Harappa, a metropolis of the Indus civilisation in the valley of Indus's tributary, the Ravi river. Masson made copious notes and illustrations of Harappa's rich historical artifacts, many lying half-buried. In 1842, Masson included his observations of Harappa in the book Narrative of Various Journeys in Baluchistan, Afghanistan, and the Punjab. He dated the Harappa ruins to a period of recorded history, erroneously mistaking it to have been described earlier during Alexander's campaign.[37] Masson was impressed by the site's extraordinary size and by several large mounds formed from long-existing erosion.[37][t]

Two years later, the Company contracted Alexander Burnes to sail up the Indus to assess the feasibility of water travel for its army.[37] Burnes, who also stopped in Harappa, noted the baked bricks employed in the site's ancient masonry, but noted also the haphazard plundering of these bricks by the local population.[37]

Despite these reports, Harappa was raided even more perilously for its bricks after the

railway lines being laid in the Punjab.[39] Nearly 160 km (100 mi) of railway track between Multan and Lahore, laid in the mid-1850s, was supported by Harappan bricks.[39]

In 1861, three years after the dissolution of the East India Company and the establishment of Crown rule in India, archaeology on the subcontinent became more formally organised with the founding of the Archaeological Survey of India (ASI).[40] Alexander Cunningham, the Survey's first director-general, who had visited Harappa in 1853 and had noted the imposing brick walls, visited again to carry out a survey, but this time of a site whose entire upper layer had been stripped in the interim.[40][41] Although his original goal of demonstrating Harappa to be a lost Buddhist city mentioned in the seventh century CE travels of the Chinese visitor, Xuanzang, proved elusive,[41] Cunningham did publish his findings in 1875.[42] For the first time, he interpreted a Harappan stamp seal, with its unknown script, which he concluded to be of an origin foreign to India.[42][43]

Archaeological work in Harappa thereafter lagged until a new viceroy of India,

Expropriating Harappa for the ASI under the Act, Marshall directed ASI archaeologist Daya Ram Sahni to excavate the site's two mounds.[44]

Farther south, along the

D. R. Bhandarkar (1911), R. D. Banerji (1919, 1922–1923), and M. S. Vats (1924).[45] In 1923, on his second visit to Mohenjo-daro, Baneriji wrote to Marshall about the site, postulating an origin in "remote antiquity", and noting a congruence of some of its artifacts with those of Harappa.[46] Later in 1923, Vats, also in correspondence with Marshall, noted the same more specifically about the seals and the script found at both sites.[46] On the weight of these opinions, Marshall ordered crucial data from the two sites to be brought to one location and invited Banerji and Sahni to a joint discussion.[47] By 1924, Marshall had become convinced of the significance of the finds, and on 24 September 1924, made a tentative but conspicuous public intimation in the Illustrated London News:[17]

"Not often has it been given to archaeologists, as it was given to Schliemann at Tiryns and Mycenae, or to Stein in the deserts of Turkestan

, to light upon the remains of a long forgotten civilisation. It looks, however, at this moment, as if we were on the threshold of such a discovery in the plains of the Indus."

In the next issue, a week later, the British Assyriologist Archibald Sayce was able to point to very similar seals found in Bronze Age levels in Mesopotamia and Iran, giving the first strong indication of their date; confirmations from other archaeologists followed.[48] Systematic excavations began in Mohenjo-daro in 1924–25 with that of K. N. Dikshit, continuing with those of H. Hargreaves (1925–1926), and Ernest J. H. Mackay (1927–1931).[45] By 1931, much of Mohenjo-daro had been excavated, but occasional excavations continued, such as the one led by Mortimer Wheeler, a new director-general of the ASI appointed in 1944, and including Ahmad Hasan Dani.[49]

After the partition of India in 1947, when most excavated sites of the Indus Valley Civilisation lay in territory awarded to Pakistan, the Archaeological Survey of India, its area of authority reduced, carried out large numbers of surveys and excavations along the Ghaggar-Hakra system in India.

Ganeriwala and Rakhigarhi.[55] As of 2008, about 616 sites have been reported in India,[20] whereas 406 sites have been reported in Pakistan.[20]

Unlike India, in which after 1947, the ASI attempted to "Indianise" archaeological work in keeping with the new nation's goals of national unity and historical continuity, in Pakistan the national imperative was the promotion of Islamic heritage, and consequently archaeological work on early sites was left to foreign archaeologists.[56] After the partition, Mortimer Wheeler, the Director of ASI from 1944, oversaw the establishment of archaeological institutions in Pakistan, later joining a UNESCO effort tasked to conserve the site at Mohenjo-daro.[57] Other international efforts at Mohenjo-daro and Harappa have included the German Aachen Research Project Mohenjo-daro, the Italian Mission to Mohenjo-daro, and the US Harappa Archaeological Research Project (HARP) founded by George F. Dales.[58] Following a chance flash flood which exposed a portion of an archaeological site at the foot of the Bolan Pass in Balochistan, excavations were carried out in Mehrgarh by French archaeologist Jean-François Jarrige and his team in the early 1970s.[59]
