The Harappan cities were generally divided into two main parts the raised area; known as the 'Citadel', and the lower town. The Citadel was more in height because the buildings in it were built on mud brick platforms. This area was separated from the lower town by a wall. The Citadel had within its fold important buildings like the Great Bath, the assembly hall, the granary and the workshops. The lower town, on the other hand had residential dwellings.

ii. The main streets of the Harappan cities were built

according to the grid pattern. They were built from north to south and from east to west.

iii. The houses built on the corners of streets were

rounded in order to allow the passage of carts. The main road in the city of Mohenjo-daro was 10.5 meters wide and 800 meters long.

iv. The house drains relayed all the waste water to the

drains built in streets.

The dearth of unifying sense of nationalism and patriotic feelings was one of the cogent contributing factors to the foundation and consolidation of the British rule in India . This unity and diversity growth helps in the rising of Indian national movement. The Indian Independence Movement was a series of activities with the ultimate aim of ending the British rule in India. The movement spanned a total of 90 years (1857–1947). The first nationalistic revolutionary movement for Indian independence emerged from Bengal.
