Pharaoh (/ˈfeɪ.roʊ/, /fɛr.oʊ/ or /fær.oʊ/) is the common title of the monarchs of ancient Egypt from the First Dynasty (c. 3150 BCE) until the Macedonian conquest in 305 BCE, although the actual term "Pharaoh" was not used contemporaneously for a ruler until circa 1200 BCE. According to Egypt's imperial cult, the Pharaohs were believed to be direct descendants of the sky god Hor.
