A national anthem (also state anthem, national hymn, national song, etc.) is generally a patriotic musical composition that evokes and eulogizes the history, traditions, and struggles of its people, recognized either by a nation's government as the official national song, or by convention through use by the people. The majority of national anthems are marches or hymns in style. The countries of Latin America, Central Asia, and Europe tend towards more ornate and operatic pieces, while those in the Middle East, Oceania, Africa, and the Caribbean use a more simplistic fanfare. Some countries that are devolved into multiple constituent states have their own official musical compositions for them (such as with the United Kingdom, Russian Federation, and the former Soviet Union); their constituencies' songs are sometimes referred to as national anthems even though they are not sovereign states.
The custom of an officially adopted national anthem became popular in the 19th century.
They are often patriotic songs that may have been in existence long before their designation as national anthem. The national anthem of the Netherlands, "Wilhelmus", adopted as national anthem in 1932, originates in the 16th century: It was written between 1568 and 1572 during the Dutch Revolt and its current melody variant was composed shortly before 1626, and was a popular orangist march during the 17th century. The Japanese national anthem, "Kimigayo" (adopted 1999), was composed in 1880, but its lyrics are taken from a Heian period (794-1185) poem.
In the early modern period, some European monarchies adopted royal anthems. Some of these anthems have survived into current use. "God Save the King/Queen", first performed in 1619, remains the royal anthem of the United Kingdom and the Commonwealth realms. La Marcha Real, adopted as the royal anthem of the Spanish monarchy in 1770, was adopted as the national anthem of Spain in 1939. Denmark retains its royal anthem, Kong Christian stod ved højen mast (1780) alongside its national anthem (Der er et yndigt land, adopted 1835). In 1802, Gia Long commissioned a royal anthem in the European fashion for the Kingdom of Vietnam.
The first national anthem to be officially adopted was La Marseillaise, for the First French Republic. Composed in 1792, it was officially adopted by the French National Convention in 1796. It was retired in favour of Chant du départ under the First French Empire, and was re-instated in 1830, in the wake of the July Revolution. From this time, it became common for newly formed nations to define national anthems, notably as a result of the Latin American wars of independence, for Argentina (1813), Peru (1821), Brazil (1831) but also Belgium (1830).
Adoption of national anthems prior to the 1930s was mostly by newly formed or newly independent states, such as the First Portuguese Republic (A Portuguesa, 1911), the Kingdom of Greece ("Hymn to Liberty", 1865), the First Philippine Republic (Marcha Nacional Filipina, 1898), Lithuania (Tauti?ka giesm?, 1919), Weimar Germany (Deutschlandlied, 1922), Republic of Ireland (Amhrán na bhFiann, 1926) or Greater Lebanon ("Lebanese National Anthem", 1927).
The Olympic Charter of 1920 introduced the ritual of playing the national anthems of the gold medal winners. From this time, the playing of national anthems became increasingly popular at international sporting events, creating an incentive for such nations that did not yet have an officially defined national anthem to introduce one.
The United States introduced the patriotic song The Star-Spangled Banner as national anthem in 1931. Following this, several nations moved to adopt as official national anthem patriotic songs that had already been in de facto use at official functions, such as Mexico (Mexicanos, al grito de guerra, composed 1854, adopted 1943), Switzerland ("Swiss Psalm", composed 1841, de facto use from 1961, adopted 1981).
By the period of decolonisation in the 1960s, it had become common practice for newly independent nations to adopt an official national anthem. Some of these anthems were specifically commissioned, such as the anthem of Kenya, Ee Mungu Nguvu Yetu, produced by a dedicated "Kenyan Anthem Commission" in 1963.
A number of nations remain without official national anthem. In these cases, there are established de facto anthems played at sporting events or diplomatic receptions. These include the United Kingdom ("God Save the Queen"), Sweden (Du gamla, Du fria) and Norway (Ja, vi elsker dette landet). Countries that have moved to officially adopt their long-standing de facto anthems since the 1990s include: Luxembourg (Ons Heemecht, adopted 1993), South Africa ("National anthem of South Africa", adopted 1997), Israel (Hatikvah, composed 1888, de facto use from 1948, adopted 2004), Italy (Il Canto degli Italiani, adopted 2017).
National anthems are used in a wide array of contexts. Certain etiquette may be involved in the playing of a country's anthem. These usually involve military honours, standing up/rising, removing headwear etc. In diplomatic situations the rules may be very formal. There may also be royal anthems, presidential anthems, state anthems etc. for special occasions.
They are played on national holidays and festivals, and have also come to be closely connected with sporting events. Wales was the first country to adopt this, during a rugby game against New Zealand in 1905. Since then during sporting competitions, such as the Olympic Games, the national anthem of the gold medal winner is played at each medal ceremony; also played before games in many sports leagues, since being adopted in baseball during World War II. When teams from two different nations play each other, the anthems of both nations are played, the host nation's anthem being played last.
In some countries, the national anthem is played to students each day at the start of school as an exercise in patriotism, such as in Tanzania. In other countries the state anthem may be played in a theatre before a play or in a cinema before a movie. Many radio and television stations have adopted this and play the national anthem when they sign on in the morning and again when they sign off at night. For instance, the national anthem of China is played before the broadcast of evening news on Hong Kong's local television stations including TVB Jade. In Colombia, it is a law to play the National Anthem at 6:00 and 18:00 on every public radio and television station, while in Thailand, "Phleng Chat Thai" is played at 08:00 and 18:00 nationwide (the Royal Anthem is used for sign-ons and closedowns instead).
The use of a national anthem outside of its country, however, is dependent on the international recognition of that country. For instance, Taiwan has not been recognized by the International Olympic Committee as a separate nation since 1979 and must compete as Chinese Taipei; its "National Banner Song" is used instead of its national anthem. In Taiwan, the country's national anthem is sung before instead of during flag-rising and flag-lowering, followed by the National Banner Song during the actual flag-rising and flag-lowering. Even within a state, the state's citizenry may interpret the national anthem differently (such as in the United States some view the U.S. national anthem as representing respect for dead soldiers and policemen whereas others view it as honoring the country generally).
Most of the best-known national anthems were written by little-known or unknown composers such as Claude Joseph Rouget de Lisle, composer of "La Marseillaise" and John Stafford Smith who wrote the tune for "The Anacreontic Song", which became the tune for the U.S. national anthem, "The Star-Spangled Banner." The author of "God Save the Queen", one of the oldest and most well known anthems in the world, is unknown and disputed.
Very few countries have a national anthem written by a world-renowned composer. Exceptions include Germany, whose anthem "Das Lied der Deutschen" uses a melody written by Joseph Haydn, and Austria, whose national anthem "Land der Berge, Land am Strome" is sometimes credited to Wolfgang Amadeus Mozart. The "Anthem of the Armenian Soviet Socialist Republic" was composed by Aram Khachaturian. The music of the "Pontifical Anthem", anthem of the Vatican City, was composed in 1869 by Charles Gounod, for the golden jubilee of Pope Pius IX's priestly ordination.
The committee charged with choosing a national anthem for the Federation of Malaya (later Malaysia) at independence decided to invite selected composers of international repute to submit compositions for consideration, including Benjamin Britten, William Walton, Gian Carlo Menotti and Zubir Said, who later composed "Majulah Singapura", the national anthem of Singapore. None were deemed suitable. The tune eventually selected was (and still is) the anthem of the constituent state of Perak, which was in turn adopted from a popular French melody titled "La Rosalie" composed by the lyricist Pierre-Jean de Béranger.
A few anthems have words by Nobel laureates in literature. The first Asian laureate, Rabindranath Tagore, wrote the words and music of "Jana Gana Mana" and "Amar Shonar Bangla", later adopted as the national anthems of India and Bangladesh respectively. Bjørnstjerne Bjørnson wrote the lyrics for the Norwegian national anthem "Ja, vi elsker dette landet".
Other countries had their anthems composed by locally important people. This is the case for Colombia, whose anthem's lyrics were written by former president and poet Rafael Nuñez, who also wrote the country's first constitution. A similar case is Liberia, the national anthem of which was written by its third president, Daniel Bashiel Warner.
A national anthem, when it has lyrics (as is usually the case), is most often in the national or most common language of the country, whether de facto or official, there are notable exceptions. Most commonly, states with more than one national language may offer several versions of their anthem, for instance:
