The Hymno Patriótico (English: Patriotic Hymn), was considered Portugal’s first national anthem. Offered to the Prince Regent D. John and first performed for the Prince in 1809, the anthem was inspired by the cantata “La Speranza o sia l’Augurio Felice”. The lyrics changed several times, altered by contemporary events, until settling into a more or less permanent form in 1821. After D. Peter of Braganza became king and provided a new constitution, the song “Hymno da Carta” became more commonly used as the anthem, and the latter was officially decreed as such in 1834.
