The "Canción Nacional" ( [kanˈsjon nasjoˈnal], ; 'National Song'), also known by its incipit Puro, Chile, es tu cielo azulado ( [ˈpuɾo ˈtʃile ˈes tu ˈsjelo asuˈlaðo], ; 'How pure, Chile, is thy blue sky'), is the national anthem of Chile. It was composed by Ramón Carnicer and first adopted in 1828. Later, the Chilean government wanted words for the song, so eventually, a poet by the name of Eusibio Lillo wrote the lyrics to the anthem in September 1847.
