In 1869, fearing another revolt, the Spanish Crown disbanded the Puerto Rican Militia, which had been composed almost entirely of native-born Puerto Ricans, and also the Compañia de Artilleros Morenos de Cangrejos, a separate company of black Puerto Ricans. They then organized the Volunteer Institute, composed entirely of Spaniards and their sons.
