The list of city flags lists the flags of cities. Most of the city flags are based on the coat of arms or emblems of its city itself, and city flags can be also used by the coat of arms and emblems on its flag. Most of the city flags are flown outside town halls and councils.
Due to its size, the list is split into continents:
Cities with metropolitan area populations of five million; largest cities without their own city flag are not included.
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.
A coat of arms is a heraldic visual design on an escutcheon, surcoat, or tabard. The coat of arms on an escutcheon forms the central element of the full heraldic achievement, which in its whole consists of a shield, supporters, a crest, and a motto. A coat of arms is traditionally unique to the armiger. The term "coat of arms" itself, describing in modern times just the heraldic design, originates from the description of the entire medieval chainmail "surcoat" garment used in combat or preparation for the latter.
A saltire, also called Saint Andrew's Cross or the crux decussata, is a heraldic symbol in the form of a diagonal cross. The word comes from the Middle French sautoir, Medieval Latin saltatoria ("stirrup").
The hammer and sickle is a communist symbol representing proletarian solidarity between agricultural and industrial workers. It was first adopted during the Russian Revolution at the end of World War I, the hammer representing workers and the sickle representing the peasants.
The flag of Nicaragua was first adopted on September 4, 1908, but not made official until August 27, 1971. It is based on, and inspired by, the flag of the Federal Republic of Central America and flag of Argentina.
In vexillography, the canton is a rectangular emblem placed at the top left of a flag, usually occupying up to a quarter of a flag's area. The canton of a flag may be a flag in its own right. For instance, British ensigns have the Union Jack as their canton, as do their derivatives such as the national flags of Australia and New Zealand.
Flag desecration is the desecration of a flag, violation of flag protocol, or various acts that intentionally destroy, damage, or mutilate a flag in public. In the case of a national flag, such action is often intended to make a political point against a country or its policies. Some countries have laws against methods of destruction or forbidding particular uses ; such laws may distinguish between the desecration of the country's own national flag and the desecration of flags of other countries. Some countries have also banned the desecration of all types of flags from inside the country to other country flags.
This armorial of sovereign states shows the coat of arms, national emblem, or seal for every sovereign state. Although some countries do not have an official national emblem, unofficial emblems which are de facto used as national emblems are also shown below.
A red star, five-pointed and filled, is a symbol that has often historically been associated with communist ideology, particularly in combination with the hammer and sickle, but is also used as a purely socialist symbol in the 21st century. It has been widely used in flags, state emblems, monuments, ornaments, and logos.
In vexillology, a state flag is either the flag of the government of a sovereign state, or the flag of an individual federated state.
A cross pattée, cross patty or Pate, or cross paty, also known as a cross formy or cross formée or Templar cross, is a type of Christian cross with arms that are narrow at the centre, and often flared in a curve or straight line shape, to be broader at the perimeter. The form appears very early in medieval art, for example in a metalwork treasure binding given to Monza Cathedral by Lombard queen Theodelinda, and the 8th-century lower cover of the Lindau Gospels in the Morgan Library. An early English example from the start of the age of heraldry proper is found in the arms of Baron Berkeley.
The eagle is used in heraldry as a charge, as a supporter, and as a crest. Heraldic eagles can be found throughout world history like in the Achaemenid Empire or in the present Republic of Indonesia. The European post-classical symbolism of the heraldic eagle is connected with the Roman Empire on one hand, and with Saint John the Evangelist on the other.
The coat of arms of Mexico is a national symbol of Mexico and depicts a Mexican (golden) eagle perched on a prickly pear cactus devouring a rattlesnake. The design is rooted in the legend that the Aztec people would know where to build their city once they saw an eagle eating a snake on top of a lake. The image has been an important symbol of Mexican politics and culture for centuries. To the people of Tenochtitlan, this symbol had strong religious connotations, and to the Europeans, it came to symbolize the triumph of good over evil.
The national flag of Mexico is a vertical tricolor of green, white, and red with the national coat of arms charged in the center of the white stripe. While the meaning of the colors has changed over time, these three colors were adopted by Mexico following independence from Spain during the country's War of Independence, and subsequent First Mexican Empire.
Military aircraft insignia are insignia applied to military aircraft to visually identify the nation or branch of military service to which the aircraft belong. 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.
A national coat of arms is a symbol which denotes an independent state in the form of a heraldic achievement. While a national flag is usually used by the population at large and is flown outside and on ships, a national coat of arms is normally considered a symbol of the government or the head of state personally and tends to be used in print, on armorial ware, and as a wall decoration in official buildings. The royal arms of a monarchy, which may be identical to the national arms, are sometimes described as arms of dominion or arms of sovereignty.
