There are multiple claimants to the position of oldest national anthem. Among the national anthems, the first to be composed was the Dutch national anthem the ""Wilhelmus"", which was written between 1568 and 1572. The Japanese anthem, ""Kimigayo"", employs the oldest lyrics of any national anthem, taking its words from the ""Kokin Wakashū"", which was first published in 905, yet these words were not set to music until 1880. The first anthem to be officially adopted as such was the Spanish anthem ""Marcha Real"", in 1770; its origins remain unclear, being suggested to have sixteenth century Venetian origins, or even to have been composed by king Frederick the Great himself; it is also one of the few national anthems that has never had official lyrics. Anthems became increasingly popular among European states in the 18th century. For example, the British national anthem ""God Save the Queen"" was first performed under the title ""God Save the King"" in 1745. The French anthem ""La Marseillaise"" was written half a century later in 1792, and adopted in 1795.
