Some Egyptologists question this legendary account, arguing that an ancient decorative carving of a ruler named Narmer bearing the royal symbols of both Upper and Lower Egypt demonstrates that it was actually he who ruled as the first pharaoh of a united Egypt. Other scholars regard Menes and Narmer as the same person. Regardless of the founding monarch's precise identity, it is beyond doubt that during eight consecutive royal dynasties that spanned most of the next thousand years, Memphis was to serve as the political, cultural, religious, and economic capital of Egypt, and based on the huge size of the cemeteries found nearby, some historians believe that it may have been the largest city in the world at the time, with a population as high as 100,000 at its peak. The longevity of Memphis as the leading Egyptian city can be ascribed to a number of important advantages it offered.
