Mohenjodaro, Larkana District, Sindh, Pakistan
Although the massive mounds of Mohenjo Dam and Harappa had been known to scholars for many years, it was only after excavations in the 1920's and 30’s that these ancient cities were identified as the product of a previously unknown civilization. The basic features of this civilization were revealed through surveys and excavations at a number of sites within the Indus River valley of Pakistan and the adjacent regions of western India, and it came to be known as the Harappa Culture or Indus Civilization. However, because of the lack of information and the fact that their writing system is still undeciphered, this culture has remained a major enigma in the field of South Asian archaeology and we have been plagued with many unanswered questions regarding its origins, its character and extent, and its decline.
