The Marcha Real is the national anthem of Spain. It is one of only four national anthems in the world to have no official lyrics. Though the Marcha Real has no lyrics, words have been written and used for it in the past. One version was used during Alfonso XIII's reign and another during General Franco's dictatorship; however, none of them were ever made official. The national anthem has been played without words since 1978, when the lyrics that had been approved by General Francisco Franco were abandoned.
