Juan Valiente was born West Africa and purchased by Portuguese traders from African slavers. Around 1530 he was purchased by Alonso Valiente to be a slaved domestic servant in Puebla, Mexico. In 1533 Juan Valiente made a deal with his owner to allow him to be a conquistador for four years with the agreement that all earnings would come back to Alonso. He fought for many years in Chile and Peru. By 1540 he was a captain, horseman, and partner in Pedro de Valdivia's company in Chile. He was later awarded an estate in Santiago; a city he would help Valdivia found. Both Alonso and Valiente tried to contact the other to make an agreement about Valiente's manumission and send Alonso his awarded money. They were never able to reach each other and Valiente died in 1553 in the Battle of Tucapel.
