Francisco Pizarro was from Spain and was sent to go explore for the Spanish crown. After he explored and conquered a lot of South America, Spain was the best country in the world.

The main reason Pizarro was sent to explore was for conquest. Spain already had lots of land in the New World. But they wanted more. So they destroyed the Incas because they wanted more land. He was like his relative, Hernando Cortez. He wiped out the Aztecs. Pizarro did the same thing but wiped our Peru. so this also expanded Spain's main religion too.
