The people of the Indus Valley gave the world its earliest towns, its urban planning, its stone and clay architecture, and showed concern for health and sanitation. They developed a sophisticated drainage network in their cities. There is enough evidence to suggest that this practice stems from some of the early concepts of Hinduism. The present civilization as a whole is a hybrid product arising from the merger of many civilizations, in which the Indus Valley 's contribution is of utmost importance.It is said that this culture has come to an abrupt end. The following explanations for her sudden end are brought forward...
Aryans murdered people and destroyed civilization in the Indus Valley. The people of Harappan had a love for peace. They had no weapons . They had hunting or farming implements. So, they couldn't defend against Aryans. Aryans' devastation of those men was a tragic occurrence in history. The Aryans lived in villages, and did not know anything about urban life. Thus India once again took hundreds of years to have beautiful cities such as Mohen-jo-daro and Harappa.
Regular floods destroyed the area :: Many peoples believe that climate change caused the collapse of Indus Valley Civilization. Some experts believe the drying of the Saraswati River, which started around 1900 BCE, was the major cause of climate change, while others conclude that the area was hit by a great flood.
The changes in river patterns caused a breakup of the large civilization into smaller communities called late Harappan cultures.- These changes included drying up the Hakra River, and changes in the Indus River course. The river changes affected agricultural and economic structures and many people left the Indus Valley region cities.
