List of national anthems
Most nation-states have an anthem, defined as "a song, as of praise, devotion, or patriotism"; most anthems are either marches or hymns in style. A song or hymn can become a national anthem under the state's constitution, by a law enacted by its legislature, or simply by tradition. A royal anthem is a patriotic song similar to a national anthem, but it specifically praises or prays for a monarch or royal dynasty. Such anthems are usually performed at public appearances by the monarch or during other events of royal importance. Some states use their royal anthem as the national anthem.
National anthems are usually written in the most common language of the state, whether de facto or official. States with multiple national languages may offer several versions of their anthem.
