The population of the new Spanish colony stood at approximately 104,000. Of this number, about 30,000 were slaves, and the rest a mixture of white, Indian, and black. The European Spaniards were few, and consisted principally of Catalans. In 1812, a group of blacks and mulattoes staged a rebellion, with the goal of annexation to the Republic of Haiti. On August 15 and 16, mulattoes José Leocadio, Pedro Seda, and Pedro Henriquez, with other conspirators, attacked the Mendoza hacienda in Mojarra in the municipality of Guerra near the capital. Seda and Henriquez were apprehended and executed; Leocadio was captured within days, hanged, dismembered, and boiled in oil. A year later enslaved laborers in the rural community El Chavón also rebelled, but they were quickly caught and executed.
