Today is a Federal holiday-- with selected state, local offices and schools closed. You may want to debate the contributions of Christopher Columbus:
- he was trying to find a route to China, and thought he got to India
- modern history states didn't prove the world was flat-- that was the current thinking of the time
- he spread small pox to Native American tribes
- he owned slaves
- he died broke.
- expanded trade and the influence of Christianity
- made Europe aware there was another continent
- exported foods of the Americans (hot peppers, tomatoes) around the world.
Enjoy your day!
