Three ships carrying 70 men departed from Sanlúcar de Barrameda on 8 October 1515, commanded by an admiral tasked with exploring the southern reaches of the American continent. Juan Díaz de Solís led this mission, aiming to navigate the eastern coastline of South America and charting the vast, unknown territories that defined the era of maritime discovery.
Early Career and Naval Experience
Origins regarding the birthplace of Díaz de Solís remain subject to historical dispute. While some accounts point to São Pedro de Solis or Lisbon, other documentation suggests he lived in Lebrija, Spain. Initially recognized as João Dias de Solis in Portugal, he served as a pilot within the Portuguese India Armadas. In 1506, he participated in the armada of Tristão da Cunha, serving on a vessel captained by Afonso de Albuquerque. Before entering the formal service of the Spanish Crown, he spent a brief period operating as a privateer within French fleets.

By 1506, he served as a navigator during expeditions to the Yucatán alongside Vicente Yáñez Pinzón, followed by a mission to Brazil in 1508. Following the death of Amerigo Vespucci in 1512, the Spanish Crown appointed him Pilot Major. In this prestigious capacity, he received the responsibility of maintaining and updating the Padrón Real, a task he performed in collaboration with Juan Vespucio.
The Final Expedition and Death
In 1516, he reached the body of water he named the Río de la Plata. During an excursion upriver toward the confluence of the Uruguay and Paraná rivers, he disembarked with two officers and seven men. The landing party faced an attack from local indigenous people. While survivors identified the Charrúa, researchers note that the Guarani were known to practice cannibalism, suggesting they were the group responsible for his death. Following his demise at Punta Gorda, his brother-in-law, Francisco de Torres, assumed command of the remaining fleet to navigate back to Spain.
