Liberia
"All Hail, Liberia Hail!"

Words by: Daniel Bashiel Warner
Music by: Olmstead Luca
Adopted: 1847 (lyrics), 1860 (music)

Founded by freed slaves from the United States in the 1820s, the words to the anthem of the second oldest independent African nation were written by the nation's third president and adopted upon independence in 1847. Presumably, the anthem first had a different melody, as the current music was written in 1860.

Special thanks to: Sun Shu Zhang for the sheet music.
