As in
Mesopotamia and Egypt, the Indus Valley, with its river Indus and its
annual floods, was the main reason for the emergence of the Indian
Valley Culture, and its great agriculture, which in turn led to a great civilization was formed that was bigger than all the ancient civilizations. Year
after year, when the Indus overflowed, the farmers had abundant
harvests, planted wheat and barley, as well as legumes, dates and
melons. The societies of farmers, with the passage
of hundreds of years, became walled cities, and the cultures of the
valley of the Indian, reached more than one million square kilometers. Harappa
and Mohenjo-Daro, (in present-day Pakistan) were the most important
cities, having their great agricultural potential, thanks to the river
Indus, as the main engine of their economy.
