The correct answer is Spain. Spain's national anthem, officially known as the "Marcha Real" (Royal March), is one of only four national anthems in the world that has no official lyrics – the others being Bosnia and Herzegovina, San Marino, and Kosovo[reference:0][reference:1]. The anthem is performed as a purely instrumental piece.
Why the Marcha Real Has No Official Lyrics
The Marcha Real originated as a military march in the 18th century. It first appeared in a 1761 military manual entitled Libro de la Ordenanza de los Toques de Pífanos y Tambores, where it was called the "Marcha Granadera" (March of the Grenadiers)[reference:2]. The melody was declared a "March of Honor" by King Charles III in 1770[reference:3] and gradually became the de facto national anthem during the reign of Queen Isabella II (1833–1868)[reference:4].
Several attempts have been made to add official lyrics over the years – including competitions in 1870 and again in 2007–2008[reference:5][reference:6]. However, none of these efforts succeeded due to political disagreements and a lack of consensus among Spain's diverse regions and political factions[reference:7]. As a result, the anthem remains without any officially recognised words.
Why the Other Options Are Incorrect
- Chile: Chile's national anthem, "Himno Nacional de Chile," has official lyrics written by Eusebio Lillo.
- Greece: The Greek national anthem, "Hymn to Liberty," has official lyrics and is also the longest national anthem in the world.
- Albania: Albania's national anthem, "Himni i Flamurit," has official lyrics written by Asdreni.
Therefore, Spain is the only country among the options whose national anthem officially has no lyrics, making it the correct answer.
