Used by the Republicans in the Spanish Civil War of 1931-1939, "Himno de Riego", written during the 19th century, had been a popular patriotic song since it was written, including at the outbreak of the war. The anthem was named after Rafael de Riego, a general during the first Spanish Civil War (1820-1823). The anthem was also used briefly at the conclusion of that war (from April 7, 1822 to 1823 on the restoration of the monarchy.) The words were written by Evaristo de San Miguel, a Spanish noble, military man and historian. The music was composed by Francisco Guerta.
The anthem was subsequently banned by Franco, who led the campaign against the republican forces in the civil war and who led the country following their defeat.
