First Dynasty of Egypt
Information about the First Dynasty comes from monuments and other objects with royal names. The most important are the Narmer palette, the Narmer Macehead and the Den and Qa'a king lists. No details of the dynasty have been found except for brief entry on the Palermo Stone. Manetho's book, Aegyptiaca is different to the archeological evidence and other historical records. Manetho names nine rulers of the First Dynasty, but only one name matches the other sources. He only has information for four of them. The hieroglyphs were fully developed and would be used with little change for more than 3000 years.
