In the beginning of what is known as the Predynastic period (3300 - 2920 B.C.), the population had gathered in two centers: one in the North, in the Delta region and the other in the South, in Hierakonopolis, where we know of sovereigns such as King Scorpion and Narmer. The last King of the Predynastic period, he conquered Lower Egypt and unified the country, no doubt after several wars. His successor, Aha - who can probably be identified with the legendary Menes - founded the 1st Dynasty (from the Greek: dynam(is) = power). The two first Dynasties were called Thinite because, according to the Greek historian, Manethon - to whom we owe a list of all thirty lineages of the Egyptian sovereigns - the pharaohs of this period came from the city of This, of which no trace was ever found, but which must have been located in the Abydos area.
