The Praieira revolt (1848–1849), which originated Recife, spread to Água Preta in its first year. Captain Pedro Ivo Veloso da Silveira (? - 1852) took refuge in the forests of Agua Preta after the defeat of his faction in Recife and organized a guerrilla resistance for two years before his surrender.[2]
