Wilhelmus van Nassouwe, usually known just as the Wilhelmus (Dutch: "Het Wilhelmus" ; ] ; English translation: the "William"), is the national anthem of the Kingdom of the Netherlands.
 It dates back to at least 1572, making it the oldest known national anthem in the world.
 The national anthem of Japan, Kimigayo, has the oldest lyrics, dating from the 9th century.
 However, a melody was added only in the late 19th century, making it a poem rather than an anthem for most of its lifespan.
 Although the "Wilhelmus" was not recognised as the official national anthem until 1932, it has always been popular with parts of the Dutch population and resurfaced on several occasions in the course of Dutch history before gaining its present status.
 It was also the anthem of the Netherlands Antilles from 1954 to 1964.
Josip Runjanin or Josif Runjanin (; 8 December 1821 – 2 February 1878) was a Croatian composer and lieutenant-colonel of the Austro-Hungarian Army of Aromanian origin.
 He is best known for composing the melody of the Croatian national anthem.
Croatian Chileans (Chileno-croatas, ] ; Croatian: "čileanski Hrvati") are an important ethnic group in Chile; they are citizens of Chile who were either born in Europe or are Chileans of Croatian descent deriving their Croatian ethnicity from one or both parents.
 Chile has one of the largest communities of ethnic Croats outside the Balkan Peninsula and it is one of the most significant Croatian communities – second only to Croats in Bosnia and Herzegovina.
 They are one of the main examples of successful assimilation of a non-Spanish-speaking European ethnic group into Chilean society.
 Many successful entrepreneurs, scientists, artists and prominent politicians holding the highest offices in the country have been of Croatian descent.
The National Anthem of the Republic of Kazakhstan (, "Qazaqstan Respuwblïkasınıñ Memlekettik Änuranı", قازاقستان زەسپۋبلئكاسىنىڭ مەملەكەتتئك أنۇرانى) was the title of the old national anthem of Kazakhstan, when it was adopted as the anthem from 1992 to early 2006.
 Upon independence in December 1991, the melody of the Kazakh SSR anthem, composed by Mukan Tulebayev, Yevgeny Brusilovsky and Latif Khamidi, was retained; and new lyrics were adopted in 1992 after a lengthy competition.
 The lyrics were written jointly by four people including poet Zhadyra Daribayeva, one of only a handful of women to have ever been involved in writing a national anthem.
The National Anthem of Bosnia and Herzegovina (Bosnian, Croatian and Serbian: "Državna himna Bosne i Hercegovine" / Државна химна Босне и Херцеговине), is the name of the official national anthem of Bosnia and Herzegovina.
 It is one of the four national anthems (along with that of Kosovo, Spain and San Marino) in the world to have no official lyrics.
 The anthem was adopted on 25 June 1999, by the promulgation of the Law on the National Anthem of Bosnia and Herzegovina, replacing the previous anthem, "Jedna si jedina", which excluded the country's Serb and Croat communities, this despite the fact that the text does not mention any nationality.
 It was in use from 10 February 1998, as the flag and coat of arms.
Croatian National Corpus (Croatian: "Hrvatski nacionalni korpus" , "HNK") is the biggest and the most important corpus of the Croatian language.
 Its compilation started in 1998 at the Institute of Linguistics of the Faculty of Humanities and Social Sciences, University of Zagreb following the ideas of Marko Tadić.
 The theoretical foundations and the expression of the need for a general-purpose, representative and multi-million corpus of the Croatian language started to appear even earlier.
 The Croatian National Corpus is compiled from selected texts written in Croatian covering all fields, topics, genres and styles: from literary and scientific texts to text-books, newspaper, user-groups and chat rooms.
The Aromanians (Aromanian: "Rrãmãnjã, Armãnjã" ) are an ethnic group native to the southern Balkans, traditionally living in northern and central Greece, central and southern Albania, the Republic of Macedonia, and south-western Bulgaria.
 Especially in Greece, the term Vlachs is widespread, but this term is internationally used to encompass all Romance-speaking peoples of the Balkans and Tatra Mountains regions, including the modern-day Romanians.
 "Vlach" is a blanket term covering several modern peoples descending from the Latinized population of the Balkans and Central-Eastern Europe.
The national anthem of Thailand was adopted on 10 December 1939.
 The melody was composed by Phra Chenduriyang (Peter Veit) and the words are by Luang Saranupraphan.
 "Phleng Chat" (Thai: เพลงชาติ ), literally meaning "national anthem", is a general word for national anthem.
 "Phleng Chat Thai" (Thai: เพลงชาติไทย ), Thailand's national anthem, is also used to refer to this specific song.
The oldest national anthem, defined as "a song, as of praise, devotion, or patriotism", is the Dutch national anthem "Het Wilhelmus", which was written between 1568 and 1572, but not then given any official status.
 The first anthem to be officially proclaimed as such was "God Save The Queen", adopted by Great Britain in 1745.
 "Het Wilhelmus" was declared the national anthem of the Netherlands in 1932; both of these anthems remain in use today.
 A royal or imperial anthem is a song that is similar in patriotic character to a national anthem, but which specifically praises a monarch, or royal dynasty.
 Some states have doubled their royal or imperial anthem as their national anthem.
Matica hrvatska (Latin: "Matrix Croatica" ) is the oldest independent, non-profit and non-governmental Croatian national institution.
 It was founded on February 2, 1842 by the Croatian Count Janko Drašković and other prominent members of the Illyrian movement during the Croatian National Revival (1835-1874).
 Its main goals are to promote Croatian national and cultural identity in the fields of art, science, spiritual creativity, economy and public life as well as to care for social development of Croatia.
