The Indus Valley Civilization (IVC) was a Bronze Age civilization (mature period 2600–1900 BCE) which centred mostly in the western part of the Indian Subcontinent or South Asia and flourished around the Indus river basin.Primarily centered along the Indus and the Punjab region, the civilization extended into the Ghaggar-Hakra River valley and the Ganges-Yamuna Doab, encompassing most of what is now Pakistan, as well as extending into the westernmost states of India, southeastern Afghanistan and the easternmost part of Balochistan, Iran.

The mature phase of this civilization is known as the Harappan Civilization as the first of its cities to be unearthed was the one at Harappa, excavated in the 1920s in what was at the time the Punjab province of British India (now in Pakistan). Excavation of IVC sites have been ongoing since 1920, with important breakthroughs occurring as recently as 1999.

The civilization is sometimes referred to as the Indus Ghaggar-Hakra civilization or the Indus-Sarasvati civilization. The appellation Indus-Sarasvati is based on the possible identification of the Ghaggar-Hakra River with the Sarasvati River of the Nadistuti sukta in the Rig Veda, but this usage is disputed on linguistic and geographical grounds.The Harappan language is not directly attested and its affiliation is unknown, a plausible relation would be to Proto-Dravidian or Elamo-Dravidian.

Discovery and excavation

The ruins of Harrappa were first described in 1842 by Charles Masson in his Narrative of Various Journeys in Balochistan, Afghanistan and the Punjab, where locals talked of an ancient city extending "thirteen cosses" (about 25 miles), but no archaeological interest would attach to this for nearly a century.

In 1856, British engineers John and William Brunton were laying the East Indian Railway Company line connecting the cities of Karachi and Lahore. John wrote: "I was much exercised in my mind how we were to get ballast for the line of the railway." They were told of an ancient ruined city near the lines, called Brahminabad. Visiting the city, he found it full of hard well-burnt bricks, and "convinced that there was a grand quarry for the ballast I wanted," the city of Brahminabad was reduced to ballast. A few months later, further north, John's brother William Brunton's "section of the line ran near another ruined city, bricks from which had already been used by villagers in the nearby village of Harappa at the same site. These bricks now provided ballast along of the railroad track running from Karachi to Lahore."

In 1872–75 Alexander Cunningham published the first Harappan seal (with an erroneous identification as Brahmi letters). It was half a century later, in 1912, that more Harappan seals were discovered by J. Fleet, prompting an excavation campaign under Sir John Hubert Marshall in 1921–22 and resulting in the discovery of the hitherto unknown civilization at Harappa by Sir John Marshall, Rai Bahadur Daya Ram Sahni and Madho Sarup Vats, and at Mohenjo-daro by Rakhal Das Banerjee, E. J. H. MacKay, and Sir John Marshall. By 1931, much of Mohenjo-Daro had been excavated, but excavations continued, such as that led by Sir Mortimer Wheeler, director of the Archaeological Survey of India in 1944. Among other archaeologists who worked on IVC sites before the partition of the subcontinent in 1947 were Ahmad Hasan Dani, Brij Basi Lal, Nani Gopal Majumdar, and Sir Marc Aurel Stein.

Following the Partition of India, the bulk of the archaeological finds were inherited by Pakistan where most of the IVC was based, and excavations from this time include those led by Sir Mortimer Wheeler in 1949, archaeological adviser to the Government of Pakistan. Outposts of the Indus Valley civilization were excavated as far west as Sutkagan Dor in Baluchistan, as far north as at Shortugai on the Amudarya or Oxus River in current Afghanistan.

Periodisation

The mature phase of the Harappan civilization lasted from c. 2600 to 1900 BCE. With the inclusion of the predecessor and successor cultures—Early Harappan and Late Harappan, respectively—the entire Indus Valley Civilization may be taken to have lasted from the 33rd to the 14th centuries BCE. Two terms are employed for the periodization of the IVC: Phases and Eras. The Early Harappan, Mature Harappan, and Late Harappan phases are also called the Regionalisation, Integration, and Localisation eras, respectively, with the Regionalization era reaching back to the Neolithic Mehrgarh II period. "Discoveries at Mehrgarh changed the entire concept of the Indus civilization," according to Ahmad Hasan Dani, professor emeritus at Quaid-e-Azam University, Islamabad. "There we have the whole sequence, right from the beginning of settled village life."

Geography

The Indus Valley Civilization encompassed most of Pakistan, extending from Balochistan to Sindh, and extending into modern day Indian states of Gujarat, Rajasthan, Haryana and Punjab, with an upward reach to Rupar on the upper Sutlej. The geography if the Indus Valley put the civilizations that arose there in a highly similar situation to those in Egypt and Peru, with rich agricultural lands being surrounded by highlands, desert, and ocean. Recently, Indus sites have been discovered in Pakistan's northwestern Frontier Province as well. Other IVC colonies can be found in Afghanistan while smaller isolated colonies can be found as far away as Turkmenistan and in Gujarat. Coastal settlements extended from Sutkagan Dor in Western Baluchistan to Lothal in Gujarat. An Indus Valley site has been found on the Oxus River at Shortughai in northern Afghanistan, in the Gomal River valley in northwestern Pakistan, at Manda on the Beas River near Jammu, India, and at Alamgirpur on the Hindon River, only 28 km from Delhi. Indus Valley sites have been found most often on rivers, but also on the ancient seacoast, for example, Balakot, and on islands, for example, Dholavira.

There is evidence of dry river beds overlapping with the Hakra channel in Pakistan and the seasonal Ghaggar River in India. Many Indus Valley (or Harappan) sites have been discovered along the Ghaggar-Hakra beds. Among them are: Rupar, Rakhigarhi, Sothi, Kalibangan, and Ganwariwala. According to J. G. Shaffer and D. A. Lichtenstein, the Harappan Civilization "is a fusion of the Bagor, Hakra, and Koti Dij traditions or 'ethnic groups' in the Ghaggar-Hakra valley on the borders of India and Pakistan."

According to some archaeologists, over 500 Harappan sites have been discovered along the dried up river beds of the Ghaggar-Hakra River and its tributaries, in contrast to only about 100 along the Indus and its tributaries; consequently, in their opinion, the appellation Indus Ghaggar-Hakra civilisation or Indus-Saraswati civilisation is justified. However, these politically inspired arguments are disputed by other archaeologists who state that the Ghaggar-Hakra desert area has been left untouched by settlements and agriculture since the end of the Indus period and hence shows more sites than found in the alluvium of the Indus valley; second, that the number of Harappan sites along the Ghaggar-Hakra river beds have been exaggerated and that the Ghaggar-Hakra, when it existed, was a tributary of the Indus, so the new nomenclature is redundant. "Harappan Civilization" remains the correct one, according to the common archaeological usage of naming a civilization after its first findspot.

Early Harappan

The Early Harappan Ravi Phase, named after the nearby Ravi River, lasted from circa 3300 BCE until 2800 BCE. It is related to the Hakra Phase, identified in the Ghaggar-Hakra River Valley to the west, and predates the Kot Diji Phase (2800-2600 BCE, Harappan 2), named after a site in northern Sindh, Pakistan, near Mohenjo Daro. The earliest examples of the Indus script date from around 3000 BCE.

The mature phase of earlier village cultures is represented by Rehman Dheri and Amri in Pakistan. Kot Diji (Harappan 2) represents the phase leading up to Mature Harappan, with the citadel representing centralised authority and an increasingly urban quality of life. Another town of this stage was found at Kalibangan in India on the Hakra River.

Trade networks linked this culture with related regional cultures and distant sources of raw materials, including lapis lazuli and other materials for bead-making. Villagers had, by this time, domesticated numerous crops, including peas, sesame seeds, dates and cotton, as well as various animals, including the water buffalo. Early Harappan communities turned to large urban centres by 2600 BCE, from where the mature Harappan phase started.

Mature Harappan

By 2600 BCE, the Early Harappan communities had been turned into large urban centers. Such urban centers include Harappa, Ganeriwala, Mohenjo-daro in modern day Pakistan and Dholavira, Kalibangan, Rakhigarhi, Rupar, Lothal in modern day India. In total, over 1,052 cities and settlements have been found, mainly in the general region of the Indus Rivers and their tributaries.

Cities

A sophisticated and technologically advanced urban culture is evident in the Indus Valley Civilization making them the first urban centers in the region. The quality of municipal town planning suggests the knowledge of urban planning and efficient municipal governments which placed a high priority on hygiene, or, alternately, accessibility to the means of religious ritual.

As seen in Harappa, Mohenjo-daro and the recently partially excavated Rakhigarhi, this urban plan included the world's first known urban sanitation systems. Within the city, individual homes or groups of homes obtained water from well. From a room that appears to have been set aside for bathing, waste water was directed to covered drains, which lined the major streets. Houses opened only to inner courtyards and smaller lanes. The house-building in some villages in the region still resembles in some respects the house-building of the Harappans.

The ancient Indus systems of sewerage and drainage that were developed and used in cities throughout the Indus region were far more advanced than any found in contemporary urban sites in the Middle East and even more efficient than those in many areas of Pakistan and India today. The advanced architecture of the Harappans is shown by their impressive dockyards, granaries, warehouses, brick platforms and protective walls. The massive walls of Indus cities most likely protected the Harappans from floods and may have dissuaded military conflicts.

The purpose of the citadel remains debated. In sharp contrast to this civilization's contemporaries, Mesopotamia and Ancient Egypt, no large monumental structures were built. There is no conclusive evidence of palaces or temples—or of kings, armies, or priests. Some structures are thought to have been granaries. Found at one city is an enormous well-built bath, which may have been a public bath. Although the citadels were walled, it is far from clear that these structures were defensive. They may have been built to divert flood waters.

Most city dwellers appear to have been traders or artisans, who lived with others pursuing the same occupation in well-defined neighborhoods. Materials from distant regions were used in the cities for constructing seals, beads and other objects. Among the artifact discovered were beautiful glazed faïence beads. Steatite seals have images of animals, people (perhaps gods) and other types of inscriptions, including the yet un-deciphered writing system of the Indus Valley Civilization. Some of the seals were used to stamp clay on trade goods and most probably had other uses as well.

Although some houses were larger than others, Indus Civilization cities were remarkable for their apparent, if relative, egalitarianism. All the houses had access to water and drainage facilities. This gives the impression of a society with relatively low wealth concentration, though clear social leveling is seen in personal adornments.

Science

The people of the Indus Civilization achieved great accuracy in measuring length, mass, and time. They were among the first to develop a system of uniform weights and measures. Their measurements are said to be extremely precise; however, a comparison of available objects indicates large scale variation across the Indus territories. Their smallest division, which is marked on an ivory scale found in Lothal, was approximately 1.704 mm, the smallest division ever recorded on a scale of the Bronze Age. Harappan engineers followed the decimal division of measurement for all practical purposes, including the measurement of mass as revealed by their hexahedron weights.

These chert weights were in a perfect ratio of 4:2:1 with weights of 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 100, 200, and 500 units, with each unit weighing approximately 28 grams, similar to the English Imperial ounce or Greek uncia, and smaller objects were weighed in similar ratios with the units of 0.871. However, as in other cultures, actual weights were not uniform throughout the area. The weights and measures later used in Kautilya's Arthashastra (4th century BCE) are the same as those used in Lothal.

Unique Harappan inventions include an instrument which was used to measure whole sections of the horizon and the tidal lock. In addition, Harappans evolved some new techniques in metallurgy and produced copper, bronze, lead and tin. The engineering skill of the Harappans was remarkable, especially in building docks after a careful study of tides, waves and currents. The function of the so-called "dock" at Lothal, however, is disputed.

In 2001, archaeologists studying the remains of two men from Mehrgarh, Pakistan, made the discovery that the people of the Indus Valley Civilisation, from the early Harappan periods, had knowledge of proto-dentistry. Later, in April 2006, it was announced in the scientific journal Nature that the oldest (and first early Neolithic) evidence for the drilling of human teeth in vivo (i.e., in a living person) was found in Mehrgarh. Eleven drilled molar crowns from nine adults were discovered in a Neolithic graveyard in Mehrgarh that dates, from 7,500-9,000 years ago. According to the authors, their discoveries point to a tradition of proto-dentistry in the early farming cultures of that region.

A touchstone bearing gold streaks was found in Banawali, which was probably used for testing the purity of gold (such a technique is still used in some parts of India).

Arts and culture

Various sculptures, seals, pottery, gold jewelry and anatomically detailed figurines in terracotta, bronze and steatite have been found at the excavation sites.

A number of gold, terra-cotta and stone figurines of girls in dancing poses reveal the presence of some dance form. Also, these terra-cotta figurines included cows, bears, monkeys, and dogs. Sir John Marshall is known to have reacted with surprise when he saw the famous Indus bronze statuette of a slender-limbed dancing girl in Mohenjo-daro:

Many crafts "such as shell working, ceramics, and agate and glazed steatite bead making" were used in the making of necklaces, bangles, and other ornaments from all phases of Harappan sites and some of these crafts are still practiced in the subcontinent today. Some make-up and toiletry items (a special kind of combs (kakai), the use of collyrium and a special three-in-one toiletry gadget) that were found in Harappan contexts still have similar counterparts in modern India. Terracotta female figurines were found (ca. 2800-2600 BCE) which had red color applied to the "manga" (line of partition of the hair).

Seals have been found at Mohenjo-daro depicting a figure standing on its head, and another sitting cross-legged in what some call a yoga-like pose (see image, the so-called Pashupati, below).

A harp-like instrument depicted on an Indus seal and two shell objects found at Lothal indicate the use of stringed musical instruments. The Harappans also made various toys and games, among them cubical dice (with one to six holes on the faces), which were found in sites like Mohenjo-Daro.

Trade and transportation

The Indus civilization's economy appears to have depended significantly on trade, which was facilitated by major advances in transport technology. These advances included bullock carts that are identical to those seen throughout South Asia today, as well as boats. Most of these boats were probably small, flat-bottomed craft, perhaps driven by sail, similar to those one can see on the Indus River today; however, there is secondary evidence of sea-going craft. Archaeologists have discovered a massive, dredged canal and what they regard as a docking facility at the coastal city of Lothal in western India (Gujarat state). An extensive canal network, used for irrigation, has however also been discovered by H.-P. Francfort.

During 4300–3200 BCE of the chalcolithic period (copper age), the Indus Valley Civilization area shows ceramic similarities with southern Turkmenistan and northern Iran which suggest considerable mobility and trade. During the Early Harappan period (about 3200–2600 BCE), similarities in pottery, seals, figurines, ornaments, etc., document intensive caravan trade with Central Asia and the Iranian plateau.

Judging from the dispersal of Indus civilisation artifacts, the trade networks, economically, integrated a huge area, including portions of Afghanistan, the coastal regions of Persia, northern and western India, and Mesopotamia.

There was an extensive maritime trade network operating between the Harappan and Mesopotamian civilizations as early as the middle Harappan Phase, with much commerce being handled by "middlemen merchants from Dilmun" (modern Bahrain and Failaka located in the Persian Gulf). Such long-distance sea trade became feasible with the innovative development of plank-built watercraft, equipped with a single central mast supporting a sail of woven rushes or cloth.

Several coastal settlements like Sotkagen-dor (astride Dasht River, north of Jiwani), Sokhta Koh (astride Shadi River, north of Pasni) and Balakot (near Sonmiani) in Pakistan along with Lothal in India testify to their role as Harappan trading outposts. Shallow harbors located at the estuary of rivers opening into the sea allowed brisk maritime trade with Mesopotamian cities.

Agriculture

Some post-1980 studies indicate that food production was largely indigenous to the Indus Valley. It is known that the people of Mehrgarh used domesticated wheats and barley, and the major cultivated cereal crop was naked six-row barley, a crop derived from two-row barley (see Shaffer and Liechtenstein 1995, 1999). Archaeologist Jim G. Shaffer (1999: 245) writes that the Mehrgarh site "demonstrates that food production was an indigenous South Asian phenomenon" and that the data support interpretation of "the prehistoric urbanization and complex social organization in South Asia as based on indigenous, but not isolated, cultural developments." Others, such as Dorian Fuller, however, indicate that it took some 2000 years before Middle Eastern wheat was acclimatised to South Asian conditions.

Writing or symbol system

Well over 400 distinct Indus symbols (some say 600) have been found on seals, small tablets, or ceramic pots and over a dozen other materials, including a "signboard" that apparently once hung over the gate of the inner citadel of the Indus city of Dholavira. Typical Indus inscriptions are no more than four or five characters in length, most of which (aside from the Dholavira "signboard") are exquisitely tiny; the longest on a single surface, which is less than 1 inch (2.54 cm) square, is 17 signs long; the longest on any object (found on three different faces of a mass-produced object) has a length of 26 symbols.

While the Indus Valley Civilization is often characterized as a literate society on the evidence of these inscriptions, this description has been challenged on linguistic and archaeological grounds: it has been pointed out that the brevity of the inscriptions is unparalleled in any known premodern literate society. Based partly on this evidence, a controversial paper by Farmer, Sproat, and Witzel (2004) argues that the Indus system did not encode language, but was instead similar to a variety of non-linguistic sign systems used extensively in the Near East and other societies. Others have claimed on occasion that the symbols were exclusively used for economic transactions, but this claim leaves unexplained the appearance of Indus symbols on many ritual objects, many of which were mass-produced in molds. No parallels to these mass-produced inscriptions are known in any other early ancient civilizations.

In a 2009 study by P. N. Rao et al. published in Science, computer scientists, comparing the pattern of symbols to various linguistic scripts and nonlinguistic systems, including DNA and a computer programming language, found that the Indus script's pattern is closer to that of spoken words, supporting the hypothesis that it codes for an as-yet-unknown language. Farmer, Sproat, and Witzel have disputed this finding, pointing out that Rao et al. did not actually compare the Indus signs with "real-world nonlinguistic systems" but rather with "two wholly artificial systems invented by the authors, one consisting of 200,000 randomly ordered signs and another of 200,000 fully ordered signs, that they spuriously claim represent the structures of all real-world nonlinguistic sign systems". Farmer et al. have also demonstrated that a comparison of a nonlinguistic system like medieval heraldic signs with natural languages yields results similar to those that Rao et al. obtained with Indus signs. They conclude that the method used by Rao et al. cannot distinguish linguistic systems from nonlinguistic ones.

Photos of many of the thousands of extant inscriptions are published in the Corpus of Indus Seals and Inscriptions (1987, 1991), edited by A. Parpola and his colleagues. Publication of a final third volume, which will reportedly republish photos taken in the 1920s and 1930s of hundreds of lost or stolen inscriptions, along with many discovered in the last few decades, has been announced for several years, but has not yet found its way into print. For now, researchers must supplement the materials in the Corpus by study of the tiny photos in the excavation reports of Marshall (1931), Mackay (1938, 1943), Wheeler (1947), or reproductions in more recent scattered sources.

Religion

In view of the large number of figurines found in the Indus valley, it has been widely suggested that the Harappan people worshipped a Mother goddess symbolizing fertility. However, this view has been disputed by S. Clark.Some Indus valley seals show swastikas which are found in later religions and mythologies, especially in Indian religions such as Hinduism, Buddhism and Jainism. The earliest evidence for elements of Hinduism are present before and during the early Harappan periodname=History> The BBC names a bath and phallic symbols of the Harappan civilization as features of the "Prehistoric religion (3000-1000BCE)".. Phallic symbols resembling the Hindu Siva lingam have been found in the Harappan remains.

Many Indus valley seals show animals. One famous seal shows a figure seated in a posture reminiscent of the Lotus position and surrounded by animals was named after Pashupati (lord of cattle), an epithet of Shiva and Rudra..

In the earlier phases of their culture, the Harappans buried their dead; however, later, especially in the Cemetery H culture of the late Harrapan period, they also cremated their dead and buried the ashes in burial urns, a transition notably also alluded to in the Rigveda, where the forefathers "both cremated (agnidagdhá-) and uncremated (ánagnidagdha-)" are invoked (RV 10.15.14).

Late Harappan

Around 1800 BCE, signs of a gradual decline began to emerge, and by around 1700 BCE, most of the cities were abandoned. However, the Indus Valley Civilization did not disappear suddenly, and many elements of the Indus Civilization can be found in later cultures. Current archaeological data suggests that material culture classified as Late Harappan may have persisted until at least c. 1000-900 BCE and was partially contemporaneous with the Painted Grey Ware culture. Archaeologists have emphasised that, just as in most areas of the world, there was a continuous series of cultural developments. These link "the so-called two major phases of urbanisation in South Asia".



A possible natural reason for the IVC's decline is connected with climate change that is also signaled for the neighboring areas of the Middle East: The Indus valley climate grew significantly cooler and drier from about 1800 BCE, linked to a general weakening of the monsoon at that time. Alternatively, a crucial factor may have been the disappearance of substantial portions of the Ghaggar Hakra river system. A tectonic event may have diverted the system's sources toward the Ganges Plain, though there is complete uncertainty about the date of this event as most settlements inside Ghaggar-Hakra river beds have not yet been dated. Although this particular factor is speculative, and not generally accepted, the decline of the IVC, as with any other civilization, will have been due to a combination of various reasons. New geological research is now being conducted by a group led by Peter Clift, from the University of Aberdeen, to investigate how the courses of rivers have changed in this region since 8000 years ago in order to test whether climate or river reorganizations are responsible for the decline of the Harappan. A 2004 paper indicated that the isotopes of the Ghaggar-Hakra system do not come from the Himalayan glaciers, and were rain-fed instead, contradicting a Harappan time mighty "Sarasvati' river.

Legacy

In the aftermath of the Indus Civilization's collapse, regional cultures emerged, to varying degrees showing the influence of the Indus Civilization. In the formerly great city of Harappa, burials have been found that correspond to a regional culture called the Cemetery H culture. At the same time, the Ochre Coloured Pottery culture expanded from Rajasthan into the Gangetic Plain. The Cemetery H culture has the earliest evidence for cremation, a practice dominant in Hinduism until today.

Historical context and linguistic affiliation

The IVC has been tentatively identified with the toponym Meluhha known from Sumerian records. It has been compared in particular with the civilizations of Elam (also in the context of the Elamo-Dravidian hypothesis) and with Minoan Crete (because of isolated cultural parallels such as the ubiquitous goddess worship and depictions of bull-leaping). The mature (Harappan) phase of the IVC is contemporary to the Early to Middle Bronze Age in the Ancient Near East, in particular the Old Elamite period, Early Dynastic to Ur III Mesopotamia, Prepalatial Minoan Crete and Old Kingdom to First Intermediate Period Egypt.

After the discovery of the IVC in the 1920s, it was immediately associated with the indigenous Dasyu inimical to the Rigvedic tribes in numerous hymns of the Rigveda. Mortimer Wheeler interpreted the presence of many unburied corpses found in the top levels of Mohenjo-daro as the victims of a warlike conquest, and famously stated that "Indra stands accused" of the descruction of the IVC. The association of the IVC witht he city-dwelling Dasyus remains alluring because the assumed timeframe of the first Indo-Aryan migration into India corresponds neatly with the period of decline of the IVC seen in the archaeological record. The discovery of the advanced, urban IVC however changed the 19th century view of early Indo-Aryan migration as an "invasion" of an advanced culture at the expense of a "primitive" aboriginal population to a gradual acculturation of nomadic "barbarians" on an advanced urban civilization, comparable to the Germanic migrations after the Fall of Rome, or the Kassite invasion of Babylonia. This move away from simplistic "invasionist" scenarios parallels similar developments in thinking about language transfer and population movement in general, such as in the case of the migration of the Greeks into Greece (between 2100 and 1600 BC), or the Indo-Europeanization of Western Europe (between 2200 and 1300 BC).

It was often suggested that the bearers of the IVC corresponded to proto-Dravidians linguistically, the breakup of proto-Dravidian corresponding to the breakup of the Late Harappan culture.Today, the Dravidian language family is concentrated mostly in southern India and northern Sri Lanka, but pockets of it still remain throughout the rest of India and Pakistan (the Brahui language), which lends credence to the theory. Finnish Indologist Asko Parpola concludes that the uniformity of the Indus inscriptions precludes any possibility of widely different languages being used, and that an early form of Dravidian language must have been the language of the Indus people. However, the proto-Dravidian origin theory is far from established, and the Harappan language remains an unknown quantity, and there are a number of hypotheses: Proto-Dravidian, Proto-Munda (or Para-Munda) and a "lost phylum" (perhaps related or ancestral to the Nihali language) have been proposed as candidates.

Latest Archaeological Findings

In September 2009, a rock engraving indicating clear remnants of Harappan culture, has been found in the Edakkal caves in neighboring Wayanaddistrict of Kerala, south India. The symbols akin to Indus valley culture links the Indus Valley civilization with South India.
