A flag is a piece of coloured cloth, normally rectangular, which is hung from a pole so that it can be stretched out by the wind and the image on the flag can be seen from a distance. Flags are normally used as symbols of countries, cities or occasionally companies. They can also be used for signalling, although this is rare now that we have global telecommunications networks.
There are various names for flags flying on ships, such as 'jack', 'ensign', 'pennant' etc. We'd rather not get bogged down in too much detail here, so you'll just have to look those up elsewhere.
History of Flags
Flags appear to have been invented in China. They arrived in Europe gradually and their use then spread from Europe to the rest of the world. The ancient Greeks, Romans and Egyptians didn't use them, instead using standards, a carved wooden figure on a pole, to lead troops in battle.
It's difficult to find out exactly when flags arrived in Europe, because historical accounts used the same word for them (vexillium) as for the old Roman standards. The Bayeux Tapestry, which was probably completed in 1077 AD, shows knights with flags hanging from their lances, proving that flags had definitely arrived in Europe by this date.
Components of a Flag
The language of heraldry ('blazonry') was invented to describe coats of arms, the complicated patterns by which knights in armour could be told apart. This language is sometimes used to describe flags, but in general people are much freer when describing flags. The main terms to know when describing a flag are:
- Hoist - the half of the flag closer to the flagpole. Flags are usually depicted with the flagpole on the left, but in real life it can of course be on either side.
- Fly - the half of the flag further from the flagpole.
- Canton, or Upper Hoist Quarter - the quarter of the flag closer to the pole and at the top. The 'top left' quarter in a normal depiction of the flag. This is the most important quarter, where special symbols are often placed.
- Charges or Devices - these are special symbols placed on the background.
One of the most popular symbols to appear on flags is the star. More than 40 countries have stars on their flag, ranging from a single star, for example Chile, to 50 stars in the flag of the United States of America.
In some cases, the stars are intended to be an actual representation of the stars in the sky, such as the flags of Brazil (a 27-star map of the southern skies) or New Zealand (a four-star depiction of the Southern Cross constellation). Usually, though, the stars are symbolic. In the case of the United States flag, each star represents a State of the Union.
Star and Crescent
The star and crescent moon together are a symbol of Islam. This combination appears on the flags of many Islamic countries, including Turkey, Tunisia, Malaysia, Pakistan, Mauritania and Azerbaijan. It is also in a modified form with more stars on the flags of Uzbekistan, Turkmenistan and Singapore.
Interestingly, the star and crescent is a very old Middle Eastern symbol which long predates Islam - coins from Byzantion (modern Istanbul) dating from the 1st Century BC clearly feature the star and crescent symbol.
Coats of Arms
Some flags have complex coats of arms and seals on them. In this category are Ecuador, Spain, Portugal, Peru, Bolivia and many small countries such as San Marino, Belize and Moldova. In general the smaller the country, the more complex they seem to want their flag.
There's no restriction on what sort of devices can be added to a flag, and some fairly unusual ones have been used across the world. Here's a sample:
- Angola - part of a cog wheel, symbolising industry
- Brazil - a map of the southern stars, each star representing a state/province of the country
- Kenya - a Masai shield and spears
- Barbados - a trident, the symbol of the sea
- Cambodia - Temple of Angkor Wat, probably Cambodia's most famous ruin
- South Korea - a yin/yang symbol and four I-ching symbols, symbolising many things including harmony, the origin of the universe, the four elements, the four seasons and the ideal family.
- Bhutan - a dragon
- Cyprus - a map of Cyprus, symbolising Cyprus
- Lebanon - a cedar tree
- Uganda - a strutting bird, the Grey Crowned Crane
Particularly Notable Flags
The Danish flag has the distinction of being the oldest national flag still in use. It is a plain white cross on a red background, but the cross is not centred - the vertical bar is positioned closer to the flagpole than to the free end of the flag, so that the left arm of the cross is much shorter than the right one, and the red sections to the left of the vertical bar are squares.
Legend has it that this flag fell from the sky, apparently directly from God, during a battle. The Danish king caught the flag before it touched the ground. He waved it and his side was encouraged to fight and they won the battle. This legend was first written down in the 16th Century, but there is clear evidence that the flag was in use as early as the 14th Century.
The Danish flag became the model for the flags of all the Scandinavian countries: Sweden uses a yellow cross on a blue background, Norway is blue on red, Iceland is red on blue, while Finland is blue on white.
The Union Jack
The United Kingdom of Great Britain and Northern Ireland has a flag which is known as the Union Jack or Union Flag1. This uses three crosses of two different types: a regular one and one like a letter X, known as a saltire. The blue background and the white saltire represent Scotland, the red cross is England and the red saltire is (Northern) Ireland.
The French national flag is called the 'Tricolour', because it has three vertical coloured stripes. Many countries use tricolours, but the French one was the first, adopted by the French revolutionaries when they first executed their king and created a republic.
The United States of America created a new flag when they achieved independence from England. They made a background of 13 stripes (7 red and 6 white), and on a blue rectangle in the canton they put 13 white stars. Each stripe and each star represented one of the states of the United States.
Originally, they didn't specify any particular arrangement for the 13 stars, and various patterns were used. The most common one had the 13 stars in a circle, but there were other arrangements as well.
When the number of states increased, it was decided to keep the number of stripes at 13, but to increase the stars to match the number of states. The present flag has 50 stars. If a 51st state ever joins the Union, some ingenuity will be required to arrange 51 stars in a pleasing and symmetrical pattern.
Australia and New Zealand
The constellation of the Southern Cross (Crux) is featured on the flags of a number of Pacific countries:
New Zealand's plan of the constellation has only four stars, the four brightest. The stars are red, but they have white borders so that they will stand out from the dark blue background.
The Australian flag is a mixture of symbolic and literal: the isolated big, seven-pointed star is symbolic, representing the seven states and territories of the Federation of Australia. The other five stars are the Southern Cross constellation again. As well as the four stars shown on the New Zealand flag, the fainter star epsilon Crucis is also depicted.
The Southern Cross constellation also appears on the flags of Samoa and of Micronesia.
The Jolly Roger
Most people will recognise the black flag with a white skull and crossed bones. It is the standard of piracy and is known as the Jolly Roger. In fact, many different pirates and privateers2 had their own personal flags. The skull and crossed cutlasses featured in the 'Pirates of the Caribbean' movies was the flag of Calico Jack Rackham. The most famous pirate of all was probably Edward Teach, known as 'Blackbeard'. His flag featured a skeleton holding a spear piercing a giant heart.
Flags of One Colour
Then raise the scarlet standard high,
Within its shade we'll live and die,
Though cowards flinch and traitors sneer,
We'll keep the red flag flying here.
The simplest flag is all one colour, with no device or insignia. Despite being so simple, such flags are rare, because there are only a limited number of colours that can be easily distinguished from each other.
Red: the all-red flag with no device was a symbol of proletariat workers uniting against their aristocratic rulers in the early days of the 20th Century. It was adopted by many communist nations, such as Albania, China, and the former USSR as a sign of communism. In fact the USSR flag was different on each side - the side normally shown was red with a yellow hammer and sickle on it. The other side was the Red Flag - plain red with no device.
Green: of all the countries of the world, only one has a flag that is just a plain field of one colour with no devices or charges. That country is Libya, and its flag is green. Green is the colour of Islam and many Islamic countries have it on their flags. The current Libyan flag was adopted in 1977.
White: a plain white flag is traditionally a sign of surrender or of willingness to discuss surrender terms.
Black: a black flag is a sign of mourning.
Yellow: a yellow flag flying on a ship is the quarantine symbol - with another flag it tells that there is sickness on board. On its own, it indicates that the ship is now clear of sickness and requests permission to enter port. Confusingly, the name 'yellow jack' is also a nickname for a sickness, yellow fever.
Because flags are symbolic of countries, there is an etiquette concerning their use. Respect for the country is accompanied by respect for their flag, and insulting the flag is considered an insult to the country. Some countries have a documented 'flag code', detailing what can and can't be done with the flag. The USA's flag code is probably the most detailed. It includes rules for flying the flag within United States Territory, such as:
- The flag must be taken down at sunset and not left flying through the night, unless it is illuminated.
- In a line of flags, the flag of the USA must be at the end of the line.
- No other flag may fly higher than the USA's flag.
Flying a flag at half mast - that is, half way up the pole - is a sign of mourning. It is often done when some notable person has died, as a sign of respect.
This practice almost caused a major incident when the UK's Princess Diana died suddenly in a car crash. It was known that Diana was not a great favourite of the ruling monarch, Elizabeth II. The Queen was on holiday in Balmoral Castle in Scotland. While the rest of the nation mourned the death of their favourite princess, the flag at Balmoral continued to fly at full mast, as though the Queen was deliberately flaunting her dislike of her ex-daughter-in-law. In fact, the rule governing the flag in Balmoral was that it was always flown at full mast when the Queen was in residence. When the protests of the people were made known to her, Elizabeth quickly ordered the flag to be lowered to half-mast, a symbol which for more than a thousand years had been reserved for the death of a monarch. In another change of tradition, she also arranged for a Union Flag to be flown at half mast at Buckingham Palace, her residence in London. Prior to this, no flag had been flown when the queen was away on holidays.
Flying the flag upside down is a traditional sign of distress in the UK and the USA. Bear in mind, though that it is quite difficult to tell when a Union Flag is upside down, and people flying an inverted American flag run the risk of being considered unpatriotic.
Flags for Signalling
Before the advent of radio communications, the easiest way for ships to signal to each other and to the port was by the use of flags. Flag codes were used, where combinations of different flags meant different things. The modern International Flag Code has 26 different flags representing the letters of the alphabet and another 10 representing the digits 0 to 9. While these could be used to spell out messages, most of them also have a particular meaning when used individually. The most famous of these is the white flag with a thick blue border which represents the letter P. Known as the 'Blue Peter', its meaning is 'The ship is about to sail'.
Probably the most extreme example of ship-to-ship signalling by flags was Nelson's message to his fleet before the Battle of Trafalgar: 'England expects that every man will do his duty'. In the code of the British Navy, every word except for the last one had a specific code symbol of three flags, while the word 'duty' was spelled out with two flags per letter. The original message had 'confides' (meaning 'is confident') in place of 'expects' but the flag officer pointed out that there was no code in the book for this word, so it would have to be spelled out letter by letter.
The flag of Saudi Arabia, unusually for a national flag, has a large chunk of writing in the middle. This means that the flag can't be made by printing through a single sheet of cloth, because the writing on the other side would be reversed. Instead, two separate flags must be made and sown together back to back. The writing is in the Arabic script and is a quotation from the Qur'an. Because of this, there is a rule that the Saudi flag is never flown at half mast: it would be disrespectful to the word of God.
The flag of Nepal is not a rectangle. It is an unusual shape which looks roughly like two triangular flags, one above the other. It is the only national flag which is non-rectangular.
While most countries have flags which are longer than they are high, Switzerland and the Vatican State have square flags.
The flag of Paraguay features three horizontal stripes with an emblem in the middle of the white stripe. But the emblem is not the same on the two sides of the flag; this is another flag that must be made from two sheets of cloth sewn together.
Another flag which is different on the two sides is the flag of the State of Oregon. Both sides feature yellow on a blue background; the front has the state seal and the words 'State of Oregon 1859'; the back has a picture of a beaver standing on a log.
