Saipan, together with Tinian, was possibly first sighted by Europeans by the Spanish expedition of Ferdinand Magellan, when it made a landing in the southern Marianas on 6 March 1521. It is likely Saipan was sighted by Gonzalo Gómez de Espinosa in 1522 on board of Spanish ship ''Trinidad'', which he commanded after the death of Ferdinand Magellan in an attempt to reach Panama. This is likely to have occurred after the sighting of the Maug Islands between the end of August and the end of September, 1522. Gonzalo de Vigo deserted in the Maugs from Gomez de Espinosa's ''Trinidad'' and in the next four years, living with the local indigenous Chamorro people, visited thirteen main islands in the Marianas and possibly Saipan among them. The first clear evidence of Europeans arriving to Saipan was by the Manila galleon ''Santa Margarita'' commanded by Juan Martínez de Guillistegui, that wrecked on the island in February, 1600 and whose survivors stayed on it for two years, until 250 were rescued by the ''Santo Tomas'' and the ''Jesus María''. The Spanish formally occupied the island in 1668, with the missionary expedition of Diego Luis de San Vitores who named it ''San José''. After 1670, it became a port of call for Spanish and occasional English, Dutch and French ships as a supply station for food and water. The native population shrank dramatically due to European-introduced diseases and conflicts over land.  The survivors were forcibly relocated to Guam in 1720 for better control and assimilation. Under Spanish rule, the island was developed into ranches for raising cattle and pigs, which were used to provision Spanish galleons on their way to Mexico.
