Which describes michigan, minnesota, iowa, and oregon during the civil war

I believe the answer is: Union States

These states fight for the abolishment of slavery during the civil war, while the states that fight to maintain slavery is called to confederate states. It's predicted that around 200,000 soldiers from the union states died during the war, especially during the earlier stage.
