The Pharaoh in ancient Egypt was the political and religious leader of the people and held the titles 'Lord of the Two Lands’ and 'High Priest of Every Temple’. The word 'pharaoh’ is the Greek form of the Egyptian pero or per-a-a, which was the designation for the royal residence and means `Great House'. The name of the residence became associated with the ruler and, in time, was used exclusively for the leader of the people.
The early monarchs of Egypt were not known as pharaohs but as kings. The honorific title of `pharaoh' for a ruler did not appear until the period known as the New Kingdom (c.1570-c.1069 BCE). Monarchs of the dynasties before the New Kingdom were addressed as `your majesty' by foreign dignitaries and members of the court and as `brother' by foreign rulers; both practices would continue after the king of Egypt came to be known as a pharaoh.
The Kingship is Established
In 3150 BCE the First Dynasty appeared in Egypt with the unification of Upper and Lower Egypt by the king Menes (c. 3150 BCE, now believed to be Narmer). Menes/Narmer is depicted on inscriptions wearing the two crowns of Egypt, signifying unification, and his reign was thought to be in accordance with the will of the gods; but the office of the king itself was not associated with the divine until later.
During the Second Dynasty of Egypt (2890-2670 BCE) King Raneb (also known as Nebra) linked his name with the divine and his reign with the will of the gods. Following Raneb, the rulers of the later dynasties were equated with the gods and with the duties and obligations due to those gods. Chief among these was the maintenance of ma'at - harmony and balance - which had been decreed by the gods and needed to be observed in order for people to live the best possible life.
Osiris was considered the first "king" of Egypt and so earthly rulers honored him, and established their own authority, by carrying the crook and the flail. The crook stood for kingship (guidance of the people) while the flail was associated with the fertility of the land (threshing wheat). The crook and flail were associated with an early powerful god named Andjety who came to be absorbed by Osiris. Once Osiris was established in tradition as the first king, he son Horus also came to associated with a pharaoh's reign.
The cylindrical objects sometimes seen in the hands of statues of Egyptian monarchs are known as the Cylinders of Pharaoh and the Rods of Horus and are thought to have been used to focus one's spiritual and intellectual energy - much in the way someone today might use Rosary Beads or Komboloi (worry beads).
THE PHARAOH WAS CONSIDERED A GOD ON EARTH, THE INTERMEDIARY BETWEEN THE GODS & THE PEOPLE.
As supreme ruler of the people, the pharaoh was considered a god on earth, the intermediary between the gods and the people. When the pharaoh came to the throne he was instantly associated with Horus - the god who had defeated the forces of chaos and restored order - and when he died, he was associated with Osiris, the god of the dead.
As such, in his role of 'High Priest of Every Temple’, it was the pharaoh’s duty to build great temples and monuments celebrating his own achievements and paying homage to the gods of the land who gave him the power to rule in this life and would guide him in the next.
Additionally, the pharaoh would officiate at religious ceremonies, choose the sites of temples and decree what work would be done (although he could not choose priests and very rarely took part in the design of a temple). As 'Lord of the Two Lands’ the pharaoh made the laws, owned all the land in Egypt, collected taxes, and made war or defended the country against aggression.
