Hernando de Soto's parents always talked about Peru as he was growing up. His family had moved to Switzerland after a coup. They were kicked out of the country, and for many years de Soto thought of Peru as this magical place.

When he was 38, de Soto moved back to Peru. He knew the country was poor, but he didn't really understand the extent of the poverty until he got there.
