The Second Carlist War, or the War of the Matiners or Madrugadores (Catalan and Spanish for early-risers, so-called from the harassing action that took place at the earliest hours of the morning), was a short civil war fought primarily in Catalonia by the Carlists under General RamA n Cabrera against the forces of the government of Isabella II. The uprising began in September 1846 and continued until May 1849, spreading to Galicia.

Theoretically, the war was fought to facilitate the marriage of Isabella with the Carlist pretender, Carlos, Count of MontemolA-n, which was supported by the moderate party and by the Carlists. The marriage never took place, as Isabella was wed to Francis of Assisa and Bourbon.

The conflict was minor, leading some historians to question even the label war. It coincided with the democratic Revolutions of 1848, when MarA-a Cristina revoked the constitution of RamA n MarA-a NarvA ez. NarvA ez himself led the counterattack against the revolt in Galicia while Fernando FernA ndez de CA rdova, captain-general of Catalonia, put down the isolated rebel cells in that region by early 1849. In June of that year, amnesty was granted to the Carlists and those who had fled returned.
