The Spanish conquistador who founded Asunción, Paraguay

Juan de Salazar de Espinosa (1508–1560) was a Spanish conquistador, founder of the Paraguayan capital, Asunción. In August 1535 he set sail from Cádiz as a member of the expeditionary Pedro de Mendoza, who set sail towards the region of the Río de la Plata. After assisting Pedro de Mendoza in the first foundation of Buenos Aires, Juan de Salazar de Espinosa was then sent to look for Juan de Ayolas, who had been sent earlier by Pedro de Mendoza to explore the Paraná and the Paraguay River.

He managed to find another member of Ayolas' party, Domingo Martínez de Irala, holed up in the Puerto de la Candelaria, which was founded by Ayolas in February 1537. While continuing his trip in the search of Ayolas, he founded a fort on the eastern banks of the Paraguay River which he named 'Our Lady of Asunción', due to that day, August 15, being the Christian celebration of the Assumption of Mary. He then traveled as far as San Pedro to look for Ayolas, only to discover that he had been killed by the Chaco indigenous peoples.

Juan de Salazar de Espinosa is credited for having founded the first permanent European settlement in this region of the Río de la Plata: Asunción, which would become the capital of Paraguay. In 1544, he was expelled to Spain for having taken sides along the disgraced former governor of the Río de la Plata, Álvar Núñez Cabeza de Vaca. He returned to the region in 1550, in an expedition led by Diego de Sanabria. He died in 1560 in the city he had founded, Asunción.
