According to historians, the history of India can be traced as far back as 5000 BC. During this time, a
civilization flourished in what is now modern Pakistan and Western India. Like most ancient civilizations, it is situated along a river - the Indus River.
The Indus Valley Civilization is the largest among the
world's ancient urban civilizations. It's contemporaries were Egypt, Mesopotamia and China. Harrapa was the central city of this civilization. The economy of Harappa seems to rely heavily on trade which caused major advances in the
technology of transportation. Harappa reached it's peak around 2500 BC but around 1900 BC people started to leave the cities and by 1800 BC most of the cities were abandoned.
