"Maamme" is the de facto national anthem of Finland. The music was composed by the German immigrant Fredrik Pacius, with original Swedish lyrics by Johan Ludvig Runeberg. It was first performed with the current melody and lyrics on 13 May 1848. Originally, it was written for the 500th anniversary of Porvoo, and for that occasion it was Runeberg himself who wrote the music.

A national anthem is a patriotic musical composition symbolizing and evoking eulogies of the history and traditions of a country or nation. The majority of national anthems are marches or hymns in style. American, Central Asian, and European nations 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 ; their constituencies' songs are sometimes referred to as national anthems even though they are not sovereign states.
