He was an avid coin collector, and he excavated ancient Indian archaeological sites looking for coins. Masson was a soldier of artillery who deserted the British army in 1827 and subsequently roamed the Punjab region. The first of these, according to World History Encyclopedia, was a man who went by the alias of Charles Masson (his real name was James Lewis). "The Indus Valley Civilization first came to the attention of the world through the work of British officer-archaeologists during the mid-1820s," Belcher said. Discovery of the Indus Valley Civilization Although archaeologists don't know the exact number of inhabitants that these cities contained, the larger urban centers, like Mohenjo-Daro and Harappa, might have had between 30,000 and 40,000 people, or possibly more, Belcher said. Many of the roads were broad avenues that were paved in baked brick with elaborate drainage systems. Indus Valley Civilization cities were characterized by sophisticated urban planning and included water control systems and grid-focused neighborhoods, with roads and alleyways laid out on the cardinal directions. Other Indus Valley Civilization cities are located in northwest India, and a few additional cities are in northeastern Afghanistan, near archaeological sites where tin and lapis lazuli, a blue metamorphic rock, were mined. Today, much of this area is part of the Punjab region, which is translated as the "land of the five rivers" in what is now Pakistan. Other Indus Valley Civilization cities were located next to different major rivers, such as the Ghaggar-Hakra, Sutlej, Jhelum, Chenab and the Ravi rivers, or on the alluvial floodplains between rivers. Many of the Indus Valley Civilization's large, well-planned cities, such as Mohenjo-Daro, Kot Diji and Chanhu-Daro, were situated along the course of the Indus River, which flows from the mountains of western Tibet, through the disputed region of Kashmir and southwestward before emptying into the Arabian Sea near the modern city of Karachi, Pakistan. The Indus Valley Civilization derives its name from the Indus River, one of the longest rivers in Asia.
