A flag is a piece of fabric with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration. The term flag is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging. Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin vexillum, meaning "flag" or "banner".
A national flag is a flag that represents and symbolizes a given nation. It is flown by the government of that nation, but can also be flown by its citizens. A national flag is typically designed with specific meanings for its colours and symbols, which may also be used separately from the flag as a symbol of the nation. The design of a national flag is sometimes altered after the occurrence of important historical events. The burning or destruction of a national flag is a greatly symbolic act.

The coat of arms of Egypt is known as the Republican Eagle or Egyptian Golden Eagle, is a heraldic golden eagle, facing the viewer's left (dexter). The eagle's breast is charged with an escutcheon bearing the red-white-black bands of the flag of Egypt rotated vertically, whilst the eagle's talons hold a scroll bearing the official name of the state written in Kufic script. The earliest version of the Eagle of Saladin was that used as the flag of Saladin, the first Sultan of Egypt, whilst the modern version of the eagle was adopted during the Egyptian Revolution of 1952. Subsequently, the modern design of the eagle of Saladin was adopted as the coat of arms of numerous other states in the Arab World, such as the United Arab Republic, North Yemen, Iraq, South Yemen, the Libyan Arab Republic, and Palestine. The current eagle was modified in 1984 to its present form.

An Islamic flag is the flag either representing an Islamic Caliphate, religious order, state, civil society, military force or other entity associated with Islam. Islamic flags have a distinct history due to the Islamic prescription on aniconism, making particular colours, inscriptions or symbols such as crescent-and-star popular choices. Since the time of the Islamic prophet Muhammad, flags with certain colours were associated with Islam according to the traditions. Since then, historical Caliphates, modern nation states, certain denominations as well as religious movements have adopted flags to symbolize their Islamic identity.

Many insignia are in the form of a circular roundel or modified roundel; other shapes such as stars, crosses, squares, or triangles are also used. Insignia are often displayed on the sides of the fuselage, the upper and lower surfaces of the wings, as well as on the fin or rudder of an aircraft, although considerable variation can be found amongst different air arms and within specific air arms over time.

Seven of these flags are the inspiration for more than 130 current national flags and ensigns.
