Diego García de Moguer

Diego García de Moguer (1484 or 1496–1544) was a Spanish explorer who also sailed for the Portuguese Crown later in life.

Spanish sources indicate that Diego García was born in Moguer in 1484 (or 1496), but there are Portuguese sources say he was born in Lisbon. However, his first expedition, in 1515, was with Juan Díaz de Solís in search of an oceanic passage leading to the Far East, returning to Spain after the death of Díaz de Solís in the Río de la Plata basin in 1516. He participated in the expedition of Ferdinand Magellan and Juan Sebastián Elcano between 1519 and 1522.

García received approval for a new voyage. On 15 January 1526 (15 August 1527 is also mentioned) he sailed from La Coruña, Cape Finisterre, in command of an expedition with three ships. The voyage was financed by merchants to find a suitable spice route, intended to follow Elcano's route and passing through the Magellan Strait. After voyaging through the Atlantic Ocean, García arrived on the south coast of Brazil. In February 1528, he explored the area around the Río de la Plata, an excursion documented in José Toribio Medina's Los viajes de Diego García de Moguer (The travels of Diego García de Moguer).

As he navigated through the Paraná River in early 1528, he met men from the Sebastian Cabot group. He was informed that Cabot was at the fort of Sancti Spiritu located at the confluence of the Paraná River in Carcaña. With a ship and a barquentine, García navigated the Paraná River, arriving at the Sancti Spiritu fort. He was surprised and indignant to find Cabot there. He ordered Captain Caro to abandon the place as he, García, alone had been charged by Spain to explore the region. However, after it was explained that Cabot was also in the service of Spain, they joined forces. García continued upstream between what are now the towns of Goya and Bella Vista where he met Cabot who forced him to cooperate in trying to find the legendary Sierra de la Plata.
