Spanish explorer and conquistador Juan Ponce de Leon was the first founder of European settlement in Puerto Rico and also became its first governor. He was also known for being the first European explorer to lead an expedition to Florida.
Ponce de Lion was also a successful gold miner who helped discover many gold mines. While in pursuit of a fountain of youth rumored to be found in an island of Bimini, he led an expedition to the coast of what would be known later as Florida. But he was killed by an Indian's poisoned arrow while trying to colonize that land.
Martin Luther King felt that if the African American people wanted justice, they should go about it in a civilized manner. Being violent, like Malcolm X, just brought about more cruelty and injustice.
