Narmer

Narmer (Ancient Egyptian: nꜥr-mr, may mean "painful catfish", "stinging catfish", "harsh catfish", or "fierce catfish"; fl. c. 3100 BC) was an ancient Egyptian king of the Early Dynastic Period, whose reign began at the end of the 4th millennium BC. He is believed to have been the successor to the Protodynastic king Ka. Many scholars consider him the unifier of Egypt and founder of the First Dynasty, and in turn the first king of a unified Egypt. He also had a prominently noticeable presence in Canaan, compared to his predecessors and successors. Neithhotep is thought to be his queen consort or his daughter.

A majority of Egyptologists believe that Narmer was the same person as Menes.

According to Manetho, Menes was a native of Thinis, located now in Sohag. Therefore, the governorate adopted an emblem featuring the king wearing the double crown of unified Egypt.
