Portugal’s national anthem is “A Portuguesa,” with music by Alfredo Keil and lyrics by Henrique Lopes de Mendonça. It was written in 1890 amid public anger over the British Ultimatum and became associated with Portugal’s republican movement. The song was adopted as the national anthem in 1911, after the establishment of the Portuguese Republic. Short excerpts remain common in sporting broadcasts, national ceremonies, patriotic videos, and humorous edits because the melody quickly signals Portugal and gives a scene an unmistakably formal, triumphant tone.
