A flag is a piece of fabric with distinctive colours and design. 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 national flag of the Netherlands is a horizontal tricolour of red, white, and blue. The current design originates as a variant of the late 16th century orange-white-blue Prinsenvlag, evolving in the early 17th century as the red-white-blue Statenvlag, the naval flag of the States-General of the Dutch Republic, making the Dutch flag the oldest tricolour flag in continuous use. As a flag that symbolises the transformation from monarchy to republic, it has inspired both the derivative Russian flag, and after the French Revolution in 1789, the vertically striped French tricolour; both flags in turn influenced many other tricolours. During the economic crisis of the 1930s, the old Prince's Flag with the colour orange gained some popularity among some people. To end the confusion, the colours red, white and blue and its official status as the national flag of the Kingdom of the Netherlands were reaffirmed by royal decree on 19 February 1937.
The national flag of France is a tricolour featuring three vertical bands coloured blue, white, and red. The design was adopted after the French Revolution, whose 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 Germany is a tricolour consisting of three equal horizontal bands displaying the national colours of Germany: black, red, and gold. The flag was first sighted in 1848 in the German Confederation. The flag was also used by the German Empire from 1848 to 1849. It was officially adopted as the national flag of the German Reich from 1919 to 1933, and has been in use since its reintroduction in the Federal Republic of Germany in 1949.
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 Luxembourg consists of three horizontal stripes, watermelon red, white and light blue, and can be in 1:2 or 3:5 ratio. It was first used between 1845 and 1848 and officially adopted in 1993. It is informally called in the country, «rout, wäiß, blo».
The flag of Newfoundland and Labrador was introduced in 1980 and was designed by Newfoundland artist Christopher Pratt. The flag design was approved by the House of Assembly of the province of Newfoundland, Canada, on May 28, 1980. It was flown for the first time on Discovery Day, June 24, 1980. The name of the province was changed to Newfoundland and Labrador by an amendment to the constitution of Canada in December 2001 at the request of the provincial legislature.
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 variant of the flag with the national coat of arms in the middle of the white fess is legally reserved for official use abroad and at sea. A similar flag with the addition of a white eagle is used as the naval ensign of Poland.
The national flag of the Russian Federation is a tricolour of three equal horizontal bands: white on the top, blue in the middle, and red on the bottom.
The coat of arms of Belgium bears a lion or, known as Leo Belgicus, as its charge. This is in accordance with article 193 of the Belgian Constitution: The Belgian nation takes red, yellow and black as colours, and as state coat of arms the Belgian lion with the motto UNITY MAKES STRENGTH. A royal decree of 17 March 1837 determines the achievement to be used in the greater and the lesser version, respectively.
The national flag of Lithuania consists of a horizontal tricolour of yellow, green, and red. It was adopted on 25 April 1918 during Lithuania's first period of independence (1918–1940), which ceased with the occupation first by the Soviet Union, and then by Nazi Germany (1941–1944). During the post-World War II Soviet occupation, from 1945 until 1988, the Flag of the Lithuanian SSR consisted first of a generic red Soviet flag with the name of the republic, in 1953 that was changed to the red flag with white and green bands at the bottom.
The 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). That middle stripe bears the Coat of Arms.
The flag of Sudan was adopted on 20 May 1970 and consists of a horizontal red-white-black tricolour with a green triangle at the hoist. The flag is based on the Arab Liberation Flag of the Egyptian Revolution of 1952.
The White Ensign, at one time called the St George's Ensign because of the simultaneous existence of a crossless version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton.
A triband is a flag consisting of three parallel stripes. These stripes may be two or three colours, and the middle stripe may contain an emblem. All tricolour flags are tribands, but not all tribands are tricolour flags, which requires three unique colours.
A French ensign is the flag flown at sea to identify a vessel as French. Several such ensigns have existed over the years as well as terrestrial flags based on the ensign motif.

The flag of Yugoslavia was the official flag of the Yugoslav state from 1918 to 1992. The flag's design and symbolism are derived from the Pan-Slavic movement, which ultimately led to the unification of the South Slavs and the creation of a united south-Slavic state in 1918.
