Naqada III is the last phase of the Naqada culture of ancient Egyptian prehistory, dating approximately from 3200 to 3000 BC. It is the period during which the process of state formation, which had begun to take place in Naqada II, became highly visible, with named kings heading powerful polities. Naqada III is often referred to as Dynasty 0 or Protodynastic Period to reflect the presence of kings at the head of influential states, although, in fact, the kings involved would not have been a part of a dynasty. They would more probably have been completely unrelated and very possibly in competition with each other. Kings' names are inscribed in the form of serekhs on a variety of surfaces including pottery and tombs.
