I think that one research topic that would be really interesting to study would be about Christopher Columbus as a person, his effects on Latin America, and how he is portrayed today. I think that it would be especially interesting to compare how he is celebrated in America versus what his actions were and how he affected these civilizations. Christopher Columbus’s importance is well known, as he opened up the New World to Europe, and researching him as a person would bring a greater understanding to both sides of the world at this time period.
Very interesting, Luca! I’d start with this Library of Congress exhibit for a quick overview: https://www.loc.gov/exhibits/1492/columbus.html
