Civil flags

A ''civil'' flag is a version of the national flag that is flown by civilians on non-government installations or craft. The use of civil flags was more common in the past, in order to denote buildings or ships that were not crewed by the military. In some countries the civil flag is the same as the

Other countries' armed forces (such as those of the United States or Switzerland) use their standard Flag of the United States, national flag, in addition, the U.S. has alongside flags and seals designed from long tradition for each of its six uniformed military services/military sub-departments in the United States Department of Defense, U.S. Department of Defense and the United States Department of Homeland Security, U.S. Department of Homeland Security. The Philippines' armed forces may use their Flag of the Philippines, standard national flag, but during times of war the flag is turned upside down. Flag of Bulgaria, Bulgaria's flag is also turned upside down during times of war. These are also considered war flags, though the terminology only applies to the flag's military usage. Large versions of the war flag flown on the warships of countries' navy, navies are known as battle ensigns. In addition besides flying the national standard or a military services' emblem flag at a military fort, base, station or post and at sea at the stern (rear) or main top mast of a warship, a Jack (flag), Naval Jack flag and other Maritime flags, Pennant (commissioning), pennants and emblems are flown at the bow (front). In times of war waving a white flag is a banner of truce, talks/negotiations or surrender. Four distinctive African flags currently in the collection of the National Maritime Museum in United Kingdom, Britain were flown in action by Itsekiri ships under the control of Nana Olomu during the conflict in the late 19th century. One is the flag generally known as the Flag of the Benin Empire, Benin Empire flag and one is referred to as Nana Olomu's flag.


International flags

Among international flags are the Flag of the United Nations, the Olympic symbols#Flag, Olympic flag, flag of NATO and the Paralympic symbols#Flag, Paralympic flag.


Maritime flags

Flags are particularly important at sea, where they can mean the difference between life and death, and consequently where the rules and regulations for the flying of flags are strictly enforced. A national flag flown at sea is known as an ensign. A courteous, peaceable merchant navy, merchant ship or yacht customarily flies its ensign (in the usual ensign position), together with the flag of whatever nation it is currently visiting at the mast (known as a courtesy flag). To fly one's ensign alone in foreign waters, a foreign port or in the face of a foreign warship traditionally indicates a willingness to fight, with cannon, for the right to do so. As of 2009, this custom is still taken seriously by many naval and port authorities and is readily enforced in many parts of the world by boarding, confiscation and other civil penalties. In some countries yacht ensigns are different from merchant ensigns in order to signal that the yacht is not carrying cargo that requires a customs declaration. Carrying commercial cargo on a boat with a yacht ensign is deemed to be smuggling in many jurisdictions. Traditionally, a vessel flying under the courtesy flag of a specific nation, regardless of the vessel's country of registry, is considered to be operating under the law of her 'host' nation. There is a system of international maritime signal flags for numerals and letters of the alphabet. Each flag or pennant has a specific meaning when flown individually. As well, Flag semaphore, semaphore flags can be used to communicate on an ''ad hoc'' basis from ship to ship over short distances. Another category of maritime flag flown by some United States Government ships is the distinctive mark. Although the United States Coast Guard has its own service ensign, all other U.S. Government ships fly the national ensign their service ensign, following United States Navy practice. To distinguish themselves from ships of the Navy, such ships historically have flown their parent organisation's flag from a forward mast as a distinctive mark. Today, for example, commissioned ships of the National Oceanic and Atmospheric Administration (NOAA) fly the National Oceanic and Atmospheric Administration#Flag, NOAA flag as a distinctive mark.


Shapes and designs

Flags are usually rectangular in shape (often in the ratio 2:3, 1:2, or 3:5), but may be of any shape or size that is practical for flying, including square, triangular, or swallow tailed. A more unusual flag shape is that of the flag of Nepal, which is in the shape of two stacked triangles. Other unusually shaped flags include the civil flags of Flag of Ohio, Ohio (a Swallowtail (flag), swallowtail); Flag of Tampa, Florida, Tampa, Florida; and Pike County, Ohio. Many flags are dyed through and through to be inexpensive to manufacture, such that the reverse side is the mirror image of the obverse (front) side, generally the side displayed when, from the observer's point of view, the flag flies from pole-side left to right. This presents two possibilities: # If the design is symmetrical in an axis parallel to the flag pole, obverse and reverse will be identical despite the mirror-reversal, such as the flag of India, Indian Flag or Flag of Canada, Canadian Flag # If not, the obverse and reverse will present two variants of the same design, one with the Flag terminology#Description of standard flag parts and terms, hoist on the left (usually considered the obverse side), the other with the hoist on the right (usually considered the reverse side of the flag). This is very common and usually not disturbing if there is no text in the design. Some complex flag designs are not intended to be shown on both sides, requiring separate obverse and reverse sides if made correctly. In these cases there is a design element (usually text) which is not symmetric and should be read in the same direction, regardless of whether the hoist is to the viewer's left or right. These cases can be divided into two types: # The same (asymmetric) design may be duplicated on both sides. Such flags can be manufactured by creating two identical through and through flags and then sewing them back to back, though this can affect the resulting combination's responsiveness to the wind. Depictions of such flags may be marked with the symbol , indicating the reverse is congruent to (rather than a mirror image of) the obverse. # Rarely, the reverse design may differ, in whole or in part, from that of the obverse. Examples of flags whose reverse differs from the obverse include the flag of Paraguay, the flag of Oregon, and the historical flag of the Soviet Union. Depictions of such flags may be marked with the symbol . Common designs on flags include crosses, stripes, and divisions of the surface, or ''field'', into bands or quarters—patterns and principles mainly derived from heraldry. A heraldic coat of arms may also be flown as a Banner#Heraldic banners, banner of arms, as is done on both the state flag of Maryland and the flag of Kiribati. The ''de jure'' flag of Libya under Muammar Gaddafi, which consisted of a rectangular field of green, was for a long period the only national flag using a single colour and no design or insignia. However, other historical states have also used flags without designs or insignia, such as the short-lived Hungarian Soviet Republic, Soviet Republic of Hungary and the more recent Muscat and Oman, Sultanate of Muscat and Oman, whose flags were both a plain field of red. Colours are normally described with common names, such as "red", but may be further specified using colorimetry, colourimetry. The largest flag flown from a flagpole worldwide, according to Guinness World Records, is the flag of the United Arab Emirates flown in Sharjah. This flag was . The largest flag ever made was the flag of Qatar; the flag, which measures at , was completed in December 2013 in Doha.


Parts of a flag

The general parts of a flag are: canton (the upper inner section of the flag), field or ground (the entire flag except the canton), the hoist (the edge used to attach the flag to the hoist), and the fly (the furthest edge from the hoist end).


Vertical flags

Vertical flags are sometimes used in lieu of the standard horizontal flag in central and eastern Europe, particularly in the German-speaking countries. This practice came about because the relatively brisk wind needed to display horizontal flags is not common in these countries. The standard horizontal flag (no. 1 in the preceding illustration) is nonetheless the form most often used even in these countries. The vertical flag (German: ''Hochformatflagge'' or ''Knatterflagge''; no. 2) is a vertical form of the standard flag. The flag's design may remain unchanged (No. 2a) or it may change, e.g. by changing horizontal stripes to vertical ones (no. 2b). If the flag carries an emblem, it may remain centred or may be shifted slightly upwards. The vertical flag for hoisting from a beam (German: ''Auslegerflagge'' or ''Galgenflagge''; no. 3) is additionally attached to a horizontal beam, ensuring that it is fully displayed even if there is no wind. The vertical flag for hoisting from a horizontal pole (German: ''Hängeflagge''; no. 4) is hoisted from a horizontal pole, normally attached to a building. The topmost stripe on the horizontal version of the flag faces away from the building. The vertical flag for hoisting from a crossbar or
banner A banner can be a flag or another piece of cloth bearing a symbol, logo, slogan or another message. A flag whose design is the same as the shield in a coat of arms (but usually in a square or rectangular shape) is called a banner of arms. Also, ...
(German: ''Bannerflagge''; no. 5) is firmly attached to a horizontal crossbar from which it is hoisted, either by a vertical pole (no. 5a) or a horizontal one (no. 5b). The topmost stripe on the horizontal version of the flag normally faces to the left.


Religious flags

Flags can play many different roles in religion. In Buddhism, prayer flags are used, usually in sets of five differently coloured flags. Several flags and banners including the Black Standard are Islamic flags, associated with Islam. Many religion in national flags, national flags and other flags include religious symbols such as the cross, the crescent, or a reference to a patron saint. Flags are also adopted by religious groups and flags such as the Jain flag, Nishan Sahib (Sikhism), the Bhagwa Dhwaj, Saffron flag (Hindu) and the Christian flag are used to represent a whole religion.

In sports

Because of their ease of signalling and identification, flags are often used in sports. * In association football, assistant referee (association football), linesmen carry small flags along the touch lines. They use the flags to indicate to the Referee (Football), referee potential infringements of the laws, or who is entitled to possession of the ball that has gone out of the field of play, or, most famously, raising the flag to indicate an offside (association football), offside offence. Officials called ''touch judges'' use flags for similar purposes in both codes of Rugby football, rugby. * In American football, American and Canadian football, referees use penalty flags to indicate that a foul has been committed in game play. The phrase used for such an indication is ''flag on the play''. The flag itself is a small, weighted handkerchief, tossed on the field at the approximate point of the infraction; the intent is usually to sort out the details after the current play from scrimmage has concluded. In American football, the flag is usually yellow; in Canadian football, it is usually orange. In the National Football League, coaches also use red challenge flags to indicate that they wish to contest a ruling on the field. * In yacht racing, flags are used to communicate information from the race committee boat to the racers. Different flags hoisted from the committee boat may communicate a false start, changes in the course, a cancelled race, or other important information. Racing boats themselves may also use flags to symbolise a protest or distress. The flags are often part of the nautical alphabetic system of
International maritime signal flags International maritime signal flags are various flags used to communicate with ships. The principal system of flags and associated codes is the International Code of Signals. Various navies have flag systems with additional flags and codes, and ...
, in which 26 different flags designate the 26 letters of the Latin alphabet. * In auto racing, auto and Motorcycle sport, motorcycle racing, racing flags are used to communicate with drivers. Most famously, a checkered flag of black and white squares indicates the end of the race, and victory for the leader. A yellow flag is used to indicate caution requiring slow speed and a red flag requires racers to stop immediately. A black flag is used to indicate penalties. : * In addition, fans of almost all sports wave flags in the stands to indicate their support for the participants. Many sports teams have their own flags, and, in individual sports, fans will indicate their support for a player by waving the flag of his or her home country. * Capture the flag is a popular children's sport. * In Gaelic football and Hurling a green flag is used to indicate a goal while a white flag is used to indicate a point * In Australian rules football, the Umpire (Australian rules football), goal umpire will wave two flags to indicate a goal (worth six points) and a single flag to indicate a behind (worth one point). * For safety, Glossary of underwater diving terminology, dive flags indicate the locations of underwater SCUBA diving, scuba divers or that diving operations are being conducted in the vicinity. * In water sports such as wakeboarding and Water-Skiing, an orange flag is held in between runs to indicate someone is in the water. * In golf, the hole is almost always marked with a flag. The flagpole is designed to fit centered within the base of the hole and is removable. Many courses will use colour-coded flags to determine a hole location at the front, middle or rear of the green. However colour-coded flags are not used in the professional tours. (A rare example of a golf course that does not use flags to mark the hole is the East Course of Merion Golf Club, which instead uses flagpoles topped by Merion Golf Club#Wicker baskets, wicker baskets.) * Flag poles with flags of all shapes and sizes are used by marching bands, drum corps, and winter guard teams use flags as a method of visual enhancement in performances.


Diplomatic flags

Some countries use diplomatic flags, such as the United Kingdom (see :File:British Ambassador Ensign.svg, image of the Embassy flag) and the Kingdom of Thailand (see :File:Embassador Flag of Thailand.svg, image of the Embassy flag). The Socialism, socialist movement uses Red flag (politics), red flags to represent their cause. The Anarchism, anarchist movement has a variety of different flags, but the primary flag associated with them is the Anarchist symbolism#Black flag, black flag. In the Spanish civil war, the anarchists used the red-and-black bisected flag. In the 20th century, the Rainbow flag (gay movement), rainbow flag was adopted as a symbol of the LGBT social movements. Its derivatives include the Bisexual pride flag, Bisexual pride and Transgender pride flags. Some of these political flags have become national flags, such as the red flag of the
Soviet Union The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national ...
and national socialist banners for Nazi Germany. The present Flag of Portugal is based on what had been the political flag of the Portuguese Republican Party previous to the 5 October 1910 revolution which brought this party to power.


Personal flags

Throughout history, monarchy, monarchs have often had personal flags (including royal standards), representing the royal person, including in personal union of national monarchies.


Vehicle flags

Flags are often representative of an individual's affinity or allegiance to a country, team or business and can be presented in various ways. A popular trend that has surfaced revolves around the idea of the 'mobile' flag in which an individual displays their particular flag of choice on their vehicle. These items are commonly referred to as car flags and are usually manufactured from high strength polyester material and are attached to a vehicle via a polypropylene pole and clip window attachment.


Swimming flags

In Australia, Canada, New Zealand, the Philippines, Ireland and the United Kingdom, a pair of red-yellow flags is used to mark the limits of the bathing area on a beach, usually guarded by surf lifesaving, surf lifesavers. If the beach is closed, the poles of the flags are crossed. The flags are coloured with a red triangle and a yellow triangle making a rectangular flag, or a red rectangle over a yellow rectangle. On many Australian beaches there is a slight variation with beach condition signalling. A red flag signifies a closed beach (in the UK also other dangers), yellow signifies strong current or difficult swimming conditions, and green represents a beach safe for general swimming. In Ireland, a red and yellow flag indicates that it is safe to swim; a red flag that it is unsafe; and no flag indicates that there are no lifeguards on duty. Blue flags may also be used away from the yellow-red lifesaver area to designate a zone for surfboarding and other small, non-motorised watercraft. Reasons for closing the beach include: * dangerous rip * hurricane warning * no lifeguards in attendance * pollution, overpolluted water * sharks * tsunami * waves too strong A surf flag exists, divided into four quadrants. The top left and bottom right quadrants are black, and the remaining area is white. International maritime signal flags, Signal flag "India" (a black circle on a yellow square) is frequently used to denote a "blackball" zone where surfboards cannot be used but other water activities are permitted.


Railway flags

Railways use a number of coloured flags. When used as wayside signals they usually use the following meanings (exact meanings are set by the individual railroad company): * red = stop * yellow = proceed with care * green or white = proceed. * a flag of any colour waved vigorously means stop * a blue flag on the side of a locomotive means that it should not be moved because someone is working on it (or on the train attached to it). A blue flag on a track means that nothing on that track should be moved. The flag can only be removed by the person or group that placed it. In the railway dominated steel industry this principle of "blue flag and tag" was extended to all operations at Bethlehem Steel, Lackawanna, New York. If a man went inside a large machine or worked on an electrical circuit for example, his blue flag and tag was sacrosanct. The "Lockout-tagout, Lock Out/Tag Out" practice is similar and now used in other industries to comply with safety regulations. At night, the flags are replaced with lanterns showing the same colours. Flags displayed on the front of a moving locomotive are an acceptable replacement for classification lights and usually have the following meanings (exact meanings are set by the individual railroad company): * white = extra (not on the timetable) * green = another section following * red = last section Additionally, a railroad brakeman will typically carry a red flag to make his or her hand signals more visible to the engineer. Railway signals are a development of railway flags.


Flagpoles

A flagpole, flagmast, flagstaff, or staff can be a simple support made of wood or metal. If it is taller than can be easily reached to raise the flag, a cord is used, looping around a pulley at the top of the pole with the ends tied at the bottom. The flag is fixed to one lower end of the cord, and is then raised by pulling on the other end. The cord is then tightened and tied to the pole at the bottom. The pole is usually topped by a flat plate or ball called a "Truck (rigging), truck" (originally meant to keep a wooden pole from splitting) or a finial in a more complex shape. Very high flagpoles may require more complex support structures than a simple pole, such as a guyed mast. Dwajasthambam are flagpoles commonly found at the entrances of South Indian Hindu temples.


Record heights

Since 26 December 2021, the List of flagpoles by height, tallest free-standing flagpole in the world is the Cairo Flagpole, located in the New Administrative Capital under construction in Egypt at a height of , exceeding the former record holders, the Jeddah Flagpole in Saudi Arabia (height: ), the Dushanbe Flagpole in Tajikistan (height: ) and the National Flag Square, National Flagpole in Azerbaijan (height: ). The flagpole in North Korea is the fourth tallest flagpole in the world, however, it is not free-standing. It is a radio tower supported flagpole. Many of these were built by American company Trident Support: the Dushanbe Flagpole, the National Flagpole in Azerbaijan, the Ashgabat Flagpole, Ashgabat flagpole in Turkmenistan at ; the Aqaba Flagpole in Jordan at ; the Raghadan Flagpole in Jordan at ; and the Abu Dhabi Flagpole in the United Arab Emirates at . The current tallest flagpole in India (and the tallest flying the tricolour) is the flagpole in Belgaum, Karnataka which was first hoisted on 12 March 2018. The tallest flagpole in the United Kingdom from 1959 until 2013 stood in Kew Gardens. It was made from a Canadian Douglas-fir tree and was in height. The current tallest flagpole in the United States (and the tallest flying an American flag) is the pole completed before Memorial Day 2014 and custom-made with an base in concrete by wind turbine manufacturer Broadwind Energy. It is situated on the north side of the Acuity Insurance headquarters campus along Interstate 43 in Sheboygan, Wisconsin, and is visible from Cedar Grove, Wisconsin, Cedar Grove. The pole can fly a 220-pound flag for in light wind conditions and a heavier 350-pound flag in higher wind conditions.


Design

Flagpoles can be designed in one piece with a taper (typically a steel taper or a entasis, Greek entasis taper), or be made from multiple pieces to make them able to expand. In the United States, ANSI, ANSI/NAAMM guide specification FP-1001-97 covers the engineering design of metal flagpoles to ensure safety.

Hoisting the flag

Hoisting the flag is the act of raising the flag on the flagpole. Raising or lowering flags, especially national flags, usually involves ceremonies and certain sets of rules, depending on the country, and usually involve the performance of a national anthem. A flag-raising squad is a group of people, usually troops, cadets, or students, that march in and bring the flags for the flag-hoisting ceremony. Flag-hoisting ceremonies involving flag-raising squads can be simple or elaborate, involving large numbers of squads. Elaborate flag-hoisting ceremonies are usually performed on national holidays. The cord or rope that ties a flag to its pole is called a halyard. Flags may have a strip of fabric along the hoist side called a ''heading'' for the halyard to pass through, or a pair of grommets for the halyard to be threaded through. Flags may also be held in position using Inglefield clips.


Flags in communication

Flag semaphore, Semaphore is a form of communication that utilises flags. The signalling is performed by an individual using two flags (or lighted wands), the positions of the flags indicating a symbol. The person who holds the flags is known as the signalman. This form of communication is primarily used by navy, naval signallers. This technique of signalling was adopted in the early 19th century and is still used in various forms today. The colours of the flags can also be used to communicate. For example; a white flag means, among other things, surrender or peace, a red flag can be used as a warning signal, and a black flag can mean war, or determination to defeat enemies. Orientation of a flag is also used for communication, though the practice is rarely used given modern communication systems. Raising a flag upside-down was indicative that the raising force controlled that particular area, but that it was in severe distress.
