The great Indus Valley Civilization, situated in modern India and West Pakistan, disappeared around 1800 BCE. The civilization eventually disappeared together with its two great cities, Mohenjo Daro and Harappa. Harappa lends its name to the great Indus valley.
Scholars have place forth differing theories to elucidate the disappearance of the Harappans, together with an Aryan Invasion and global climate change marked by overwhelming monsoons.
The Aryan Invasion Theory (C. 1800-1500 BC)
The Indus Valley Civilization could have met its end because of invasion. Consistent with one theory by British archeologist Roger de Mortimer Wheeler, a nomadic, Indo-European tribe, referred to as the Aryans, suddenly overpowered and conquered the Indus River valley.
Wheeler, who was Director-General of the archeologic Survey of Republic of India from 1944 to 1948, posited that a lot of unburied corpses found within the high levels of the Mohenjo-Daro archeologic site were victims of war. The speculation instructed that by victimization horses and additional advanced weapons against the peaceful Harappan individuals, the Aryans could have simply defeated them.
Various components of the Indus Civilization are found in later cultures, suggesting the civilization failed to disappear suddenly because of an invasion. Several students came to believe an Indo-Aryan Migration theory stating that the Harappan culture was assimilated throughout a migration of the Aryan individuals into the northwest Republic of India.

The temperature change Theory (C. 1800-1500 BC)
Another scholarship suggests the collapse of Harappan society resulted from global climate change. Some specialists believe the drying of the Saraswati stream, that began around 1900 BCE, was the most cause for climate change, whereas others conclude that an excellent flood affected the realm.
Any major environmental modification, like deforestation, flooding or droughts because of a stream ever-changing course, may have had fateful effects on Harappan society, like crop failures, starvation, and unwellness this conjointly would have caused a breakdown within the economy.
Another fateful modification within the Harappan climate might need to be eastward-moving monsoons or winds that bring significant rains. Monsoons will be each useful and prejudicious to a climate, looking on whether or not they support or destroy vegetation and agriculture.

By 1800 BCE, the Indus valley climate grew cooler and drier, and a tectonic event could have entertained the Ghaggar Hakra stream system toward the Ganges Plain. The Harappans could have migrated toward the Ganges basin within the east, wherever they established villages and isolated farms.
These little communities couldn’t turn out an equivalent agricultural surplus to support massive cities. With the reduced production of products, there was a decline in trade with Egypt and Mesopotamia. By around 1700 BCE, most of the Indus Valley Civilization cities had been abandoned.
