of the trans-Pacific sailing route from Acapulco to Manila, in what was then a Spanish colony. History Pre-Columbian By the 8th century around the Acapulco Bay area, there was a small culture which would first be dominated by the Olmecs, then by a number of others during the pre-Hispanic period before it ended in the 1520s. At Acapulco Bay itself, there were two Olmec sites, one by Playa Larga and the other on a hill known as El Guitarrón. Olmec influence caused the small spread-out villages here to coalesce into larger entities and build ceremonial centers. Later, Teotihuacan influence came to the area via Cuernavaca and Chilpancingo. Then Mayan influence arrived from the Isthmus of Tehuantepec and through what is now Oaxaca. This history is known through the archaeological artifacts that have been found here, especially at Playa Hornos, Pie de la Cuesta, and Tambuco. In the 11th century, new waves of migration of Nahuas and Coixas came through here. These people were the antecedents of the Aztecs. In the later 15th century, after four years of military struggle, Acapulco became part of the Aztec Empire during the reign of Ahuizotl (1486–1502). It was annexed to a tributary province named Tepecuacuilco. However, this was only transitory, as the Aztecs could only establish an unorganized military post at the city's outskirts. The city was in territory under control of the Yopes, who continued defending it and living there until the arrival of the Spanish in the 1520s. 16th century There are two stories about how Acapulco bay was discovered by Europeans. The first states that two years after the Spanish conquest of the Aztec Empire, Hernán Cortés sent explorers west to find gold. The explorers had subdued this area after 1523, and Captain Saavedra Cerón was authorized by Cortés to found a settlement here. The other states that the bay was discovered on December 13, 1526, by a small ship named the El Tepache Santiago captained by Santiago Guevara. The first encomendero was established in 1525 at Cacahuatepec, which is still part of the modern Acapulco municipality. In 1531, a number of Spaniards, most notably Juan Rodriguez de Villafuerte, left the Oaxaca coast and founded the village of Villafuerte where the city of Acapulco now stands. Villafuerte was unable to subdue the local native peoples, and this eventually resulted in the Yopa Rebellion in the region of Cuautepec. Hernán Cortés was
