The Pharaoh[a] is term that denotes monarch of ancient Egypt. The title is derived from word pr ꜥꜣ ("Great House") that initially was used as description of Royal Palace as an institution.
Pharaohs were kings of ancient Egypt. Though the term pharaoh referring to the king was not used in ancient Egypt until the New Kingdom period (c. 1539–c. 1077 bce), it is now used for all kings of ancient Egypt on the basis of its use in the Hebrew Bible.
Pharaohs were the heads of state and religious leaders of ancient Egypt.
The word Pharaoh is indeed rooted in authentic Ancient Egyptian language: it simply evolved in meaning over time, and later took on the form we know today. “Pharaoh” is the modern, Greek-derived form of the original Ancient Egyptian term 𓉐𓉻 (pr-ˁˁ), pronounced “per-ah” (or “pair-ah”)
Early ancient Egypt was ruled by kings, and only from the New Kingdom period (c. 1570 - c. 1069 BCE) did the title of ' pharaoh ' appear. Considered a god on earth and the supreme ruler of his people, a pharaoh was one of the most powerful rulers of any ancient civilization.
Egyptians believed that the pharaoh was a living god on earth, often associated with gods like Horus during life and Osiris after death. This divine status gave the pharaoh ultimate authority and placed him at the center of both religious and state affairs.
