Marcos Portugal, who had remained living in Portugal, had, in 1808, initially named the piece as 'the Prince's Hymn' ("D. Joao VI Hymn"). With this dedication, it was offered to the Prince Regent D. John and first performed for him in Brazil 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. Context_2 : "Thaxted" is a hymn tune by the English composer Gustav Holst, based on the stately theme from the middle section of the "Jupiter" movement of his orchestral suite "The Planets" and named after Thaxted, the English village where he resided much of his life. He adapted the theme in 1921 to fit the patriotic poem "I Vow to Thee, My Country" by Cecil Spring Rice but that was as a unison song with orchestra. It did not appear as a hymn-tune called "Thaxted" until his friend Ralph Vaughan Williams included it in "Songs of Praise" in 1926. This setting was sung at the Funeral of Diana, Princess of Wales, in 1997. Context_3 : "Song of Liberty" is a British patriotic song which became popular during the Second World War.
