2. Geographical location and discovery:

It was called the Harrapan Civilization, after Harappa, the first of its sites to be excavated, in what was then the Punjab province of British India and is now in Pakistan. Initially, many archaeologists thought they had found ruins of the ancient Maurya Empire, a large empire which dominated ancient India between c. 322 and 185 BCE.
Mohenjo Daro, or "Mound of the Dead" is an ancient Indus Valley Civilization city that flourished between 2600 and 1900 BCE. The site was discovered in the 1920s and lies in Pakistan's Sindh province. Only a handful of archaeologists have excavated here, described in the introduction and illustrated essay Mohenjodaro: An Ancient Indus Valley Metropolis.
