Narmer was an Egyptian pharaoh who ruled in the 32nd century BC. The successor of Serket, he is considered by some to be the founder of the First dynasty. The famous Narmer Palette, discovered in 1898, shows Narmer displaying the insignia of both Upper and Lower Egypt, giving rise to the theory that he unified the two kingdoms. As Menes is traditionally credited with that unification, this has caused some controversy. Some Egyptologists hold that Menes and Narmer are in fact the same person; some hold that Menes inherited an already-unified Egypt from Narmer; others hold that Narmer began the process of unification but either did not succeed or succeeded only partially, leaving it to Menes to complete.
