The "Brazilian National Anthem" was composed by Francisco Manuel da Silva in 1831 and had been given at least two sets of unofficial lyrics before a 1922 decree by president Epitácio Pessoa gave the anthem its definitive, official lyrics, by Joaquim Osório Duque-Estrada, after several changes were made to his proposal, written in 1909. The anthem's lyrics have been described as Parnassian in style and Romantic in content.
