papyrus reed representing Lower Egypt - a sign of the unified rule of both parts of Egypt which was followed by all succeeding rulers. In mythology, the unification of Egypt is portrayed as the falcon-god, called Horus and identified with Lower Egypt, as conquering and subduing the god Set, who was identified with Upper Egypt. Divine kingship, which would persist in Egypt for the next three millennia, was firmly established as the basis of Egypt's government. The unification of societies along the Nile has also been linked to the end of the African humid period. Funeral practices for the peasants would have been the same as in predynastic times, but the rich demanded something more. Thus, the Egyptians began construction of the mastabas which became models for the later Old Kingdom constructions such as the step pyramid. Cereal agriculture and centralization contributed to the success of the state for the next 800 years. It seems certain that Egypt became unified as a cultural and economic domain long before its first king ascended to the throne in the lower Egyptian city of Memphis. Political unification proceeded gradually, perhaps over a period of a few centuries, as local districts established trading networks and as the ability of their governments to organize agriculture labor on a larger scale increased. Divine kingship may also have gained spiritual momentum as the cults of gods like Horus, Set and Neith associated with living representatives became widespread in the country. It was also during this period that the Egyptian writing system was further developed. Initially, Egyptian writing had been composed primarily of a few symbols denoting amounts of various substances. By the end of the 3rd dynasty it had been expanded to include more than 200 symbols, both phonograms and ideograms. First Pharaoh According to Manetho, the first monarch of the unified Upper and Lower Egypt was Menes, who is now identified with Narmer. Indeed, Narmer is the earliest recorded First Dynasty monarch: he appears first on the necropolis seal impressions of Den and Qa'a. This shows that Narmer was recognized by the first dynasty kings as an important founding figure. Narmer is also the earliest king associated to the symbols of power over the two lands (see in particular the Narmer Palette, a votive cosmetic palette showing Narmer wearing the crowns of Upper and Lower Egypt) and may therefore be the first king to achieve the
