The Indus valley civilization also known as the Harappan culture is one of the earliest urban civilizations. About 500 years ago a group of nomads travelling from Sumeria entered North western India and settled there without hesitation
The civilization’s anchor lay in the beautiful twin cities of Mohenjo-daro and Harappa. These cities were made of bricks either baked mud or wood bricks and amazingly every brick were of the same size.
City’s population was about 10,000 and had very modern methods of sanitation and sewerage. Located below the great mountain range it was abundant with water and fertile soil making agriculture as the main occupation. Further proof of this is the presence of a large well it central marketplace and several granaries in the city. The Great Bath the great public bath house was near the granary. The beautiful bath aria had a layer of natural tar preventing water from leaking.
Houses were well protected from odour and thieves. Each house opened out onto inner courtyards and smaller lanes. So it was safe. Although some houses were larger than the others the city seemed to promote an equal society for all houses had the same kind of access to water and drainage.
The city had an impressive defense structure in place as well it lacked outer walls, but there were defensive towers in the West and South. Since other Indus cities had stronger defense systems in place. It is speculated that perhaps Moherjo_Daro was only an administrative centre.
