Documented Ancient Egyptian history spans from 3100 BC until about 332 BC when the Ptolemaic period began. Egyptologists have divided the history into periods and dynasties to make it easier to identify and reference times. Below is a brief introduction to ancient Egyptian history, with listing of the periods, dynasties and the kings who reigned during these times.
This period was before writing was invented (before 3100 BC), no records existed of the culture of state at that time which caused archeologists to talk about this period from traces of human life found in and around the Nile Valley. Cultures during this periods are known as Naqada I and II the former being the earlier and latter being the later.
Not much is known about the political situation during this period, it is believed however that two confederations existed, one centered in the South (Naqada) with Seth as the chief Diety and the other in the North (Behdet) with Horus (Falcon God) as the chief diety. The two confederations eventually merged into one with Menes who is shown wearing both crowns on some palettes.
