Advance Indus Valley civilization of Har'rapa in old Times | Pakistan

The civilization was first identified in 1921 at Harappa in the Punjab region and then in 1922 at Mohenjo-daro (Mohenjodaro), near the Indus River in the Sindh (Sind) region. Both sites are in present-day Pakistan, in Punjab and Sindh provinces, respectively. The ruins of Mohenjo-daro were designated a UNESCO World Heritage site in 1980.
The Indus River Valley civilization, also known as the Harappan civilization after the first site of their discovery, is a Bronze Age culture that spanned roughly from 3300 to 1300 BC. It stood toe to toe with the three other ancient heavyweights of the world — Egypt, Mesopotamia, and ancient China — often surpassing their scientific achievements; out of the four ancient cradles of civilization, the people of the Indus Valley could claim to be the largest and arguably most prosperous.
