Harappan Civilisation The Indus Valley Civilization (IVC) was a Bronze Age civilization (3300–1300 BCE; mature period 2600–1900 BCE) extending from what today is northeast Afghanistan to Pakistan and northwest India. Along with Ancient Egypt and Mesopotamia it was one of three early civilizations of the Old World, and of the three the most widespread covering an area of 1.25 million km2.It flourished in the basins of the Indus River, one of the major rivers of Asia, and the Ghaggar-Hakra River, which once coursed through northwest India and eastern Pakistan. Inhabitants of the ancient Indus river valley developed new techniques in handicraft (carnelian products, seal carving) and metallurgy (copper, bronze, lead, and tin). The Indus cities are noted for their urban planning, baked brick houses, elaborate drainage systems, water supply systems, and clusters of large non-residential buildings. The Indus Valley Civilization is also known as the Harappan Civilization, after Harappa, the first of its sites to be excavated in the 1920s, in what was then the Punjab province of British India, and is now in Pakistan. The discovery of Harappa, and soon afterwards, Mohenjo-Daro, was the culmination of work beginning in 1861 with the founding of the Archaeological Survey of India in the British Raj.The Harappan civilization is sometimes called the Mature Harappan culture to distinguish it from these cultures. By 1999, over 1,056 cities and settlements had been found, of which 96 have been excavated, mainly in the general region of the Indus and Ghaggar-Hakra Rivers and their tributaries. The Harappan language is not directly attested and its affiliation is uncertain since the Indus script is still undeciphered. Skeletal remains at Harappan sites belonged to proto-Australoid, Mongoloid, Mediterranean and AlpineThe 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. 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 lifeGeography :The Indus Valley Civilization encompassed most of Pakistan and parts of northwestern India, Afghanistan and Iran, extending from Balochistan in the west to Uttar Pradesh in the east, northeastern Afghanistan to the north and Maharashtra to the south.The geography of 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, Jammu on the Beas River near Jammu, India, and at Alamgirpur on the Hindon River, only 28 km from Delhi.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. 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 dated to 3rd millennium BC. Discoveries from Bhirrana, Rajasthan, in India, by archeologist K. N. Dikshit indicate that Hakra ware from this area dates from as early as 7500 BC. 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 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 centres. Such urban centres include Harappa,Ganeriwala, Mohenjo-Daro in modern day Pakistan, and Dholavira, Kalibangan, Rakhigarhi, Rupar, and Lothal in modern day India. In total, more than 1,052 cities and settlements have been found, mainly in the general region of the Indus Rivers and their tributaries.Cities :The quality of municipal town planning suggests the knowledge of urban planning and efficient municipal governments which placed a high priority on hygiene, or, alternatively, accessibility to the means of religious ritual.Within the city, individual homes or groups of homes obtained water from wells. 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
