Christopher Columbus
Source: wikipedia.org
He “discovered” America for Europeans, Columbus Day in America is hailed throughout the world as the Hispanic Heritage Day, the country of Colombia is named after him, as is the capital of the United States (District of Columbia), but why are we never taught that this guy was a tyrant and mass murderer?
Columbus was appointed Governor of the Indies after his first voyage, and he ruled Hispaniola and the new world along with his brothers Bartolomé and Diego. Unfortunately, their rulership was plagued with reports of tyranny, torture, violence, and mutilation against native peoples and subordinates. Upon returning home from their third voyage, the Columbus brothers were imprisoned in Spain for six weeks.
