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".
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 Romania is a tricolour. The Constitution of Romania states that "The flag of Romania is tricolour; the colours are arranged vertically in the following order from the flagpole: blue, yellow, red". The flag has a width-length ratio of 2:3; the proportions, shades of colour as well as the flag protocol were established by law in 1994, and extended in 2001.
The flag of Vatican City was adopted in 1929, the year Pope Pius XI signed the Lateran Treaty with Italy, creating the new independent state of Vatican City governed by the Holy See. The flag is a vertical bicolour of yellow and white, with the white half charged with the coat of arms of Vatican City. It was modeled after the 1808 flag of the Papal States, a yellow-and-white bicolour defaced with the tiara and keys in the centre.
The flag of England is the national flag of England, a constituent country of the United Kingdom. It is derived from Saint George's Cross. The association of the red cross as an emblem of England can be traced back to the Late Middle Ages when it was gradually, increasingly, used alongside the Royal Banner. It became the only saint's flag permitted to be flown in public as part of the English Reformation and at a similar time became the pre-eminent maritime flag referred to as a white ensign. It was used as a component in the design of the Union Jack in 1606.
The national flag of Croatia or The Tricolour is one of the state symbols of Croatia. It consists of three equal size, horizontal stripes in colours red, white and blue. In the middle is the coat of arms of Croatia.
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 as representing the hope of the nation (green) and the blood of those who died defending it (red), to endow them with a more patriotic and dignified, therefore less political, sentiment.
A maritime flag is a flag designated for use on ships, boats, and other watercraft. Naval flags are considered important at sea and the rules and regulations for the flying of flags are strictly enforced. The flag flown is related to the country of registration: so much so that the word "flag" is often used symbolically as a metonym for "country of registration".
The commissioning pennant is a pennant flown from the masthead of a warship. The history of flying a commissioning pennant dates back to the days of chivalry with their trail pendants being flown from the mastheads of ships they commanded. Today, the commissioning pennants are hoisted on the day of commissioning and not struck until they are decommissioned. Some navies have a custom of flying a "paying off" or "decommissioning pennant," the length of which often reflects the length of service of the warship.
Each of the 26 modern cantons of Switzerland has an official flag and a coat of arms. The history of development of these designs spans the 13th to the 20th centuries.
The flag of Great Britain, commonly known as King's Colours, the first Union Flag, the Union Jack, or the British flag, was used at sea from 1606 and more generally from 1707 to 1801. It was the first flag of the Kingdom of Great Britain. It is the precursor to the Union Jack of 1801.
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number. Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship.
Commodore (Cdre) is a rank of the Royal Navy above captain and below rear admiral. It has a NATO ranking code of OF-6. The rank is equivalent to brigadier in the British Army and Royal Marines and to air commodore in the Royal Air Force. Commodore has only been a substantive rank in the Royal Navy since 1997. Until then the term denoted a functional position rather than a formal rank, being the title bestowed on the senior officer of a fleet of at least two naval vessels comprising an independent command.
The island nation of Malta has a variety of national flags and symbols, some current and some no longer in use.
The municipal flag of Springfield, Illinois, is the lawful flag of the capital of the U.S. state of Illinois, Springfield. Its background is "Old Glory blue". The flag is emblazoned with a circle of 20 small, white stars, all pointed upward; the circle is offset, slightly, to the left of the flag. Those stars encircle a large, white-bordered "Old Glory red" star, also pointed upward. The center star is described as two stars, one atop the other, in the Springfield, Illinois Code of Ordinances. In the past, the flag has the words "Springfield Illinois," across its bottom; now photographs show no lettering on the flag, and governmental buildings have been seen sporting a version absent text.
