On March 21, 1890, at a conference dedicated to the during the Third Carlist War, Miguel de Unamuno delivered a lecture titled "La última guerra carlista como materia poética". It was probably the first-ever attempt to examine the Carlist motive in literature, as for the previous 57 years the subject had been increasingly present in poetry, drama and novel. However, it remains paradoxical that when Unamuno was offering his analysis, the period of great Carlist role in letters was just about to begin. It lasted for some quarter of a century, as until the late 1910s Carlism remained a key theme of numerous monumental works of Spanish literature. Afterward, it lost its appeal as a literary motive, still later reduced to instrumental role during Francoism. Today it enjoys some popularity, though no longer as catalyst of paramount cultural or political discourse; its role is mostly to provide exotic, historical, romantic, and sometimes mysterious setting.
