Pharaohs were the kings of ancient Egypt. A couple were women, but most pharaohs were men.
People referred to Pharaoh, not "the" pharaoh, but simply as Pharaoh. There was only one pharaoh (at a time) and in ancient Egypt, everything belonged to Pharaoh. When a new pharaoh came to power, everything in ancient Egypt automatically belonged to the new pharaoh.
Pharaoh was a living god. He ruled by divine right. Even thought Pharaoh was a living god, in the beginning of ancient Egypt, the people could talk directly to Pharaoh. As time went by, and the population grew and expanded, the Egyptian kings began to rely on their viziers to talk for them to the people. The vizier was the highest rank in government, next only to Pharaoh.
