The Indus valley civilization is said to be the earliest civilizations in India and in the world. It is also known as the Harappan culture. About 5000years ago a group of people travelling from Someria the present Iran, entered Northwest India near Karachi. These people found the land so richly fertile on the banks of river Indus. This place has made an amazing habitat. Gradually, the immigrants spread all over a million square miles. This civilization laid with two beautiful cities of Mohenjo-daro and Harappa. The city was built around 2600 BC. They are made up of bricks of baked mud. The bricks were of the same size which is a significant factor. The city were built with the best sanitation system, each house had a well, the city has been built with an excellent drainage sewage system connecting every house.
Evidences say, that the people main occupation would be agriculture has it consists of a rich fertile soil and rivers. Another predominant factor is the great public bath, which involves a huge courtyard, it has an excellent architecture and has been assumed to be for ritual purposes. The houses were designed with safety and are noise resistant.
The civilization has no evidence of religion, governance or authority. It seems to promote equality showing that all houses contains the same kind of facilities. This civilization existed between 3300-1300 BC. There are no signs of army, weapons and the people were been more interested in trading rather than war. They were expected to be relying on a peaceful livelihood. By 1300BC the entire civilization of Harappans are gone. The reason for their extinction would be due to climate change, poverty, reduction in trade. As the factors suggest there is no evidence for battles or any other destruction.
