National flag
From Wikipedia, the free encyclopedia
A national flag is a flag that symbolises a country and that can usually be flown by citizens of that country.
Both public and private buildings such as schools and courthouses often fly the national flag. In some countries, the national flags are only flown from non-military buildings on certain flag days.
There are three distinct types of national flag for use on land, and three for use at sea, although many countries use identical designs for several (and sometimes all) of these types of flag.

[edit] National flags on land
On land, there is a distinction between civil flags (FIAV symbol 
), state flags (
), and war or military flags (
). State flags are those used officially by government agencies, whereas civil flags may be flown by anyone irrespective of whether they are linked to government. War flags (also called military flags) are used by military organisations such as armies.
In practice, many countries (including the United States and the United Kingdom) have identical flags for these three purposes; national flag is sometimes used as a vexillological term to refer to such a three-purpose flag (
). In a number of countries, however — notably those in Latin America — there is a distinct difference between civil and state flags. In most cases, the civil flag is a simplified version of the state flag, the difference often being the presence of a coat of arms on the state flag which is absent from the civil flag.
Very few countries use a war flag that differs from the state flag; the People's Republic of China is a notable exception.
[edit] National ensigns at sea
- See also: Gallery of maritime flags
Many countries have special national flags for use at sea called national ensigns. Again, there are three varieties: the civil ensign (
), flown by private vessels; state ensigns (also called government ensigns; 
), flown by government ships; and war ensigns (also called naval ensigns; 
), flown by naval vessels. The ensign is flown from an ensign-staff at the stern of the ship, or from a gaff when underway. Both these positions are superior to any other on the ship, even though the masthead is higher. In the absence of a gaff the ensign may be flown from the yardarm. (See Maritime flags.) National flags may also be flown by aircraft and the vehicles of important officials.
In some countries, such as the United States and France, the national ensign is identical to the national flag, while in others, such as the United Kingdom and Japan, there are specific ensigns for maritime use. Most countries do not have a separate state ensign, although the United Kingdom is a rare exception, in having a red ensign for civil use, a white ensign as its naval ensign, and a blue ensign for government non-military vessels.
[edit] Similar flags
- See also: Gallery of confusable flags
Although the national flag is meant to be a unique symbol for a country, many pairs of countries have highly similar and thus easily confusable flags. Examples include the flags of Monaco and of Indonesia, which differ only slightly in proportion; of the Netherlands and of Luxembourg, which differ in proportion as well as in the shade of blue used; and of Romania and of Chad, which are almost completely identical.
While some similarities are coincidental, others are rooted in shared histories. For example, the flags of Venezuela, of Colombia, and of Ecuador all use variants of the flag of Great Colombia, the country they comprised upon their independence from Spain, created by the Venezuelan independence hero Francisco de Miranda; and the flags of Egypt, of Iraq, of Syria, and of Yemen are all highly similar variants of the flag of the Arab revolt of 1916–1918.
Many other similarities may be found among current national flags, particularly if inversions of color schemes are considered (e.g., compare the flag of Côte d'Ivoire to that of Ireland). Still more identical or closely similar pairs exist comparing present day and historical flags; for example, the current national flag of Albania was the war flag of the Byzantine (Eastern Roman) Empire.
[edit] Flag protocol
There is a great deal of protocol involved in the proper display of national flags. For example, national flags should never be flown upside down (where this is possible) except as a distress signal.
There are many regulations concerning the display of national flags, but the general rule is that the national flag should be flown in the position of honor, and not in an inferior position to any other flag (although some countries make an exception for royal standards). The following regulations are typical.
- When a national flag is displayed together with any other flags, it must be hoisted first and lowered last.
- When a national flag is displayed together with the national flags of other countries, all the flags should be of approximately equal size and must be flown at an equal height, although the national flag of the host country should be flown in the position of honour (in the center of an odd number of flagstaffs or at the far right — left from an observer's point of view — of an even number of flagstaffs).
- When a national flag is displayed together with flags other than national flags, it should be flown on a separate flagstaff, either higher or in the position of honor.
- When a national flag is displayed together with any other flags on the same flagstaff, it must be at the top, though separate flagstaffs are preferable.
- When a national flag is displayed together with any other flag on crossed staffs, the national flag must be on the observer's left and its staff must be in front of the staff of the other flag.
- When a national flag is displayed together with another flag or flags in procession, the national flag must be on the marching right. If there is a row of flags, it should be in the position of honor.
- When a national flag, with some exceptions, is flown upside down it indicates distress.
[edit] Trivia
- The flags of Switzerland and Vatican City are the only national flags which are exact squares. The Nepali flag is the only national flag which is not rectangular.
- The flag of the Philippines is unique in being flown upside-down (with red on top) when the nation is at war.
- The most popular colour combinations are: red, white, and blue (mainly European and Western nations) and red, yellow, and green (mainly African nations) The Olympic rings - blue, yellow, black, green and red represent colours used at least once in every national flag around the world.
- The Flag of Libya is the only flag that consists of only one color, green.
- Cyprus is the only country to display its land area on its official flag.
