The vizier was the highest official in ancient Egypt to serve the pharaoh (king) during the Old, Middle, and New Kingdoms. Vizier is the generally accepted rendering of ancient Egyptian tjati, tjaty etc., among Egyptologists. The Instruction of Rekhmire, a New Kingdom text, defines many of the duties of the tjaty, and lays down codes of behavior. The viziers were often appointed by the pharaoh. During the 4th Dynasty and early 5th Dynasty, viziers were exclusively drawn from the royal family; from the period around the reign of Neferirkare Kakai onwards, they were chosen according to loyalty and talent or inherited the position from their fathers.

Ancient Egypt was a civilization of ancient Northeast Africa. It was concentrated along the lower reaches of the Nile River, situated in the place that is now the country Egypt. Ancient Egyptian civilization followed prehistoric Egypt and coalesced around 3100 BC with the political unification of Upper and Lower Egypt under Menes. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by periods of relative instability known as “Intermediate Periods.” The various kingdoms fall into one of three categories: the Old Kingdom of the Early Bronze Age, the Middle Kingdom of the Middle Bronze Age, or the New Kingdom of the Late Bronze Age.
