A Portuguesa

"A Portuguesa" is the national anthem of Portugal. It was composed by Alfredo Keil and written by Henrique Lopes de Mendonça during the resurgent nationalist movement ignited by the 1890 British Ultimatum to Portugal concerning its African colonies. Used as the marching song of the failed republican revolt of 31 January 1891, in Porto, it was adopted as the national anthem of the newborn Portuguese Republic in 1911, replacing "Hino da Carta", the anthem of the deposed constitutional monarchy.
