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 national flag of France is a tricolour featuring three vertical bands coloured blue, white, and red. It is known to English speakers as the Tricolour, although the flag of Ireland and others are also known as such. The design was adopted after the French Revolution, where the revolutionaries were influenced by the horizontally striped red-white-blue flag of the Netherlands. While not the first tricolour, it became one of the most influential flags in history. The tricolour scheme was later adopted by many other nations in Europe and elsewhere, and, according to the Encyclopædia Britannica has historically stood "in symbolic opposition to the autocratic and clericalist royal standards of the past".
The national flag of Sweden consists of a yellow or gold Nordic cross on a field of light blue. The Nordic cross design traditionally represents Christianity. The design and colours of the Swedish flag are believed to have been inspired by the present coat of arms of Sweden of 1442, which is blue divided quarterly by a cross pattée of gold. Blue and yellow have been used as Swedish colours at least since Magnus III's royal coat of arms of 1275.
The national flag of Poland consists of two horizontal stripes of equal width, the upper one white and the lower one red. The two colours are defined in the Polish constitution as the national colours.

A similar flag with the addition of a white eagle is used as the naval ensign of Poland.

There is a blue canton in the upper hoist-side corner bearing a white cross; the cross symbolises Eastern Orthodox Christianity. The blazon of the flag is Azure, four bars Argent; on a canton of the field a Greek cross throughout of the second. The official flag ratio is 2:3. The shade of blue used in the flag has varied throughout its history, from light blue to dark blue, the latter being increasingly used since the late 1960s. It was officially adopted by the First National Assembly at Epidaurus on 13 January 1822.

The flag of Portugal is the national flag of the Portuguese Republic. It is a rectangular bicolour with a field divided into green on the hoist, and red on the fly. The lesser version of the national coat of arms of Portugal is centered over the colour boundary at equal distance from the upper and lower edges. Its presentation was done on 1 December 1910, after the downfall of the constitutional monarchy on 5 October 1910. However, it was only on 30 June 1911, that the official decree approving this flag as the official flag was published. This new national flag for the First Portuguese Republic, was selected by a special commission whose members included Columbano Bordalo Pinheiro, João Chagas and Abel Botelho. The conjugation of the new field color, especially the use of green, was not traditional in the Portuguese national flag's composition and represented a radical republican-inspired change that broke the bond with the former monarchical flag. Since a failed republican insurrection on 31 January 1891, red and green had been established as the colours of the Portuguese Republican Party and its associated movements, whose political prominence kept growing until it reached a culmination period following the Republican revolution of 5 October 1910. In the ensuing decades, these colours were popularly propagandised, green represented the hope of the nation and the colour red represented the blood of those who died defending it, this happened to endow them with a more patriotic and dignified, therefore less political, sentiment.
The national flag of Spain, as it is defined in the Constitution of 1978, consists of three horizontal stripes: red, yellow and red, the yellow stripe being twice the height of each red stripe. Traditionally, the middle stripe was defined by the more archaic term of gualda, and hence the popular name la Rojigualda (red-weld).

In military organizations, the practice of carrying colours, standards, flags, or guidons, both to act as a rallying point for troops and to mark the location of the commander, is thought to have originated in Ancient Egypt some 5,000 years ago. The Roman Empire also made battle standards reading SPQR a part of their vast armies. It was formalized in the armies of Europe in the High Middle Ages, with standards being emblazoned with the commander's coat of arms.

Since the dissolution of the Netherlands Antilles on 10 October 2010, it has been the sole flag used in the constituent country.
For most of its history, the Eastern Roman (Byzantine) Empire did not use heraldry in the Western European sense of permanent motifs transmitted through hereditary right. Various large aristocratic families employed certain symbols to identify themselves; the use of the cross, and of icons of Christ, the Theotokos and various saints is also attested on seals of officials, but these were often personal rather than family emblems. Likewise, various emblems were used in official occasions and for military purposes, such as banners or shields displaying various motifs such as the cross or the labarum. Despite the abundance of pre-heraldic symbols in Byzantine society from the 10th century, only through contact with the Crusaders in the 12th century, and particularly following the Fourth Crusade (1202–1204) and the establishment of Frankish principalities on Byzantine soil from 1204 onwards, did heraldic uses penetrate in Byzantium. A native Byzantine heraldry began to appear in the middle and lower rungs of aristocratic families in the 14th century, coinciding with the decline of imperial authority and with the fragmentation of political power under the late Palaiologan emperors. However, it never achieved the breadth of adoption, or the systematization, of its Western analogues.
