The total population of the civilization is thought to have been upward of 5 million, and its territory stretched over 900 miles (1,500 km) along the banks of the Indus River and then in all directions outward. Indus Valley Civilization sites have been found near the border of Nepal, in Afghanistan, on the coasts of India, and around Delhi, to name only a few locations.īetween c. 1500 BCE, the civilization began to decline for unknown reasons. In the early 20th century CE, this was thought to have been caused by an invasion of light-skinned peoples from the north known as Aryans who conquered a dark-skinned people defined by Western scholars as Dravidians. This claim, known as the Aryan Invasion Theory, has been discredited. The Aryans – whose ethnicity is associated with the Iranian Persians – are now believed to have migrated to the region peacefully and blended their culture with that of the indigenous people while the term Dravidian is understood now to refer to anyone, of any ethnicity, who speaks one of the Dravidian languages. When Masson returned to Britain after his adventures (and having been somehow forgiven his desertion), he published his book Narrative of Various Journeys in Balochistan, Afghanistan and the Punjab in 1842 CE which attracted the attention of the British authorities in India and, especially, Alexander Cunningham. L 3 CIVILIZATION V IMAGES PROFESSIONALġ814-1893 CE), a British engineer in the country with a passion for ancient history, founded the Archaeological Survey of India (ASI) in 1861 CE, an organization dedicated to maintaining a professional standard of excavation and preservation of historic sites.

Cunningham began excavations of the site and published his interpretation in 1875 CE (in which he identified and named the Indus Script) but this was incomplete and lacked definition because Harappa remained isolated with no connection to any known past civilization which could have built it.

In 1904 CE, a new director of the ASI was appointed, John Marshall (l. 1876-1958 CE), who later visited Harappa and concluded the site represented an ancient civilization previously unknown. He ordered the site to be fully excavated and, at about the same time, heard of another site some miles away which the local people referred to as Mohenjo-daro (“the mound of the dead”) because of bones, both animal and human, found there along with various artifacts. Excavations at Mohenjo-daro began in the 1924-1925 season and the similarities of the two sites were recognized the Indus Valley Civilization had been discovered. Harappa did not conform to either Egyptian or Mesopotamian architecture, however, as there was no evidence of temples, palaces, or monumental structures, no names of kings or queens or stelae or royal statuary. The city spread over 370 acres (150 hectares) of small, brick houses with flat roofs made of clay.
