Franz den Kaiser". The "Hymn of the Soviet Union", was used until its dissolution in 1991, and was given new words and adopted by the Russian Federation in 2000 to replace an instrumental national anthem that had been introduced in 1990. "Bro Gozh ma Zadoù", the regional anthem of Brittany and, "Bro Goth Agan Tasow", the Cornish regional anthem, are sung to the same tune as that of the Welsh regional anthem "Hen Wlad Fy Nhadau", with similar words. For parts of states Some countries, such as the former Soviet Union, Spain, and the United Kingdom, among others, are held to be unions of several "nations" by various definitions. Each of the different "nations" may have their own anthem and these songs may or may not be officially recognized; these compositions are typically referred to as regional anthems though may be known by other names as well (e.g. "state songs" in the United States). Austria In Austria, the situation is similar to that in Germany. The regional anthem of Upper Austria, the "Hoamatgsang" (), is notable as the only (official) German-language anthem written – and sung – entirely in dialect. Belgium In Belgium, Wallonia uses "Le Chant des Wallons" and Flanders uses "De Vlaamse Leeuw". Brazil Most of the Brazilian states have official anthems. Minas Gerais uses an adapted version of the traditional Italian song "Vieni sul mar" as its unofficial anthem. During the Vargas Era (1937–1945) all regional symbols including anthems were banned, but they were legalized again by the Eurico Gaspar Dutra government. Canada The Canadian province of Newfoundland and Labrador, having been the independent Dominion of Newfoundland before 1949, also has its own regional anthem from its days as a dominion and colony of the UK, the "Ode to Newfoundland". It was the only Canadian province with its own anthem until 2010, when Prince Edward Island adopted the 1908 song "The Island Hymn" as its provincial anthem. Czechoslovakia Czechoslovakia had a national anthem composed of two parts, the Czech anthem followed by one verse of the Slovak one. After the dissolution of Czechoslovakia, the Czech Republic adopted its own regional anthem as its national one, whereas Slovakia did so with slightly changed lyrics and an additional stanza. Germany In Germany, many of the Länder (states) have their own anthems, some of which predate the unification of Germany in 1871. A prominent example is the Hymn of Bavaria,
