Native-born Puerto Rican (criollos) had petitioned the Spanish Crown to serve in the regular Spanish army, resulting in the 1741 organization of the Regimiento Fijo de Puerto Rico. The Fijo served in the defense of Puerto Rico and other Spanish overseas possessions, performing in battles in Santo Domingo, other islands in the Caribbean, and South America, most notably in Venezuela. However, Puerto Rican complaints that the Fijo was being used to suppress the revolution in Venezuela caused the Crown to bring the Fijo home and in 1815 it was mustered out of service.[19]
