Ancient Egyptian royal titulary

The royal titulary or royal protocol is the standard naming convention taken by the pharaohs of ancient Egypt. It symbolised worldly power and holy might, also acting as a sort of mission statement for the duration of a monarch's reign (although sometimes it even changed during the reign).
The full titulary, consisting of five names, did not come into standard usage until the Middle Kingdom but remained in use as late as the Roman Empire.
In order that the pharaoh, who held divine office, could be linked to the people and the gods, special epithets were created for them at their accession to the throne. These titles also served to demonstrate one's qualities and link them to the terrestrial realm. The five names were developed over the centuries beginning with the Horus name. This name identified the figure as a representative of the god Horus. The Nebty name was the second part of the royal titular of Upper and Lower Egypt. This name placed the king under the protection of two female deities, Nekhbet and Wadjet and began sometime towards the end of the First Dynasty as a reference to "The one who belongs to Upper and Lower Egypt", along with mention of the Two Ladies. Beginning sometime in the Fourth Dynasty of Egypt, the Gold Falcon name (sometimes called the Horus of Gold) was created. The last two names of the king, the prenomen and the nomen, were generally depicted within the circular, roped cartouche of the king (eventually the cartouche would contain all royal names, including the queen and the royal children) and were known as the Throne name and the Son of Re name.

The Horus name is the oldest form of the pharaoh's name, originating in prehistoric Egypt. Many of the oldest-known Egyptian pharaohs were known only by this title.
The Horus name was usually written in a serekh, a representation of a palace façade. The name of the pharaoh was written in hieroglyphs inside this representation of a palace. Typically an image of the falcon god Horus was perched on top of or beside it.
At least one Egyptian ruler, the Second Dynasty pharaoh Seth-Peribsen, used an image of the god Set instead of Horus, perhaps signifying an internal religious division within the country. He was succeeded by Khasekhemwy, who placed the symbols of both Set and Horus above his name. Thereafter, the image of Horus always appeared alongside the name of the pharaoh.
By the time of the New Kingdom, the Horus name was often written without the enclosing serekh.
The Nebty name (lit. "two ladies") was associated with the so-called "heraldic" goddesses of Upper and Lower Egypt:
The name is first definitively used by the First Dynasty pharaoh Semerkhet, though it only became a fully independent title by the Twelfth Dynasty.
This particular name was not typically framed by a cartouche or serekh, but always begins with the hieroglyphs of a vulture and cobra resting upon two baskets, the dual noun "nebty".
Also known as the Golden Horus name, this form of the pharaoh's name typically featured the image of a Horus falcon perched above or beside the hieroglyph for gold.
The meaning of this particular title has been disputed. One belief is that it represents the triumph of Horus over his uncle Set, as the symbol for gold can be taken to mean that Horus was "superior to his foes". Gold also was strongly associated in the ancient Egyptian mind with eternity, so this may have been intended to convey the pharaoh's eternal Horus name.
Similar to the Nebty name, this particular name typically was not framed by a cartouche or serekh.
The pharaoh's throne name, the first of the two names written inside a cartouche, usually accompanied the title nsw-bity (nsw(t)-bjt(j)), traditionally interpreted as "[He] of sedge [and] bee" and often translated for convenience as "King of Upper and of Lower Egypt". (The sedge and the bee symbolised Upper and Lower Egypt, respectively, although recent research has thrown this interpretation into doubt.)
The epithet nb tꜣwy, "Lord of the Two Lands", referring to the valley and delta regions of Egypt, often occurs as well.
This was the name given at birth. The name itself was preceded by the title "Son of Ra", written with the hieroglyph of a duck (za), a homonym for the word meaning "son" (za), adjacent to an image of the sun, a hieroglyph for the chief solar deity Ra. It was first introduced to the set of royal titles in the Fourth Dynasty and emphasizes the king's role as a representative of the solar god Ra. For women who became pharaoh, the preceding title was interpreted as "daughter" also.
Modern historians typically refer to the ancient kings of Egypt by this name, adding ordinals (e.g. "II", "III") to distinguish between different individuals bearing the same name.
