Spanish conquest of the Aztec Empire
After the Spanish conquest of the Aztec Empire, Petatlán was part of an encomienda belonging to Ginés de Pinzón. Evangelization was carried out under Augustinian Juan Bautista Moya. This same friar gathered the dispersed peoples to found the modern town in 1550. This town became a dependency of the subdelegation of Zacatuna in 1786.
