A Portuguesa (pronounce [ɐ puɾtuˈɣezɐ]) is the national anthem of Portugal. It was written by Henrique Lopes de Mendonça (lyrics) and Alfredo Keil (music) after the nationalist resurgence provoked by the British Ultimatum (for Portuguese troops to vacate the territory between Angola and Mozambique), was adopted as a Republican anthem and, finally, by the new Portuguese Republic in 1910 as the national anthem, replacing "O Hino da Carta", the last anthem of the Constitutional Monarchy in Portugal.
