The opera was written between 1897 and 1902, the first of a projected trilogy of Arthurian operas commissioned by the librettist. After completing Merlin, Albéniz worked on the second part of the trilogy, Lancelot, in 1902–03, but broke off work and did not complete it before his death in 1909. He did not even begin the final part, Guinevere (Barulich 2001).
