Semerkhet

Semerkhet is the Horus name of an early Egyptian king who ruled during the First Dynasty. This ruler became known through a tragic legend handed down by the historian Manetho, who reported that a calamity of some sort occurred during Semerkhet's reign. The archaeological records seem to support the view that Semerkhet had a difficult time as king and some early archaeologists questioned the legitimacy of Semerkhet's succession to the Egyptian throne.
