If they had, they would have started by passing a constitution amendment abolishing slavery. They did the opposite. They overwhelmingly passed the Corwin Amendment, which left black people in slavery forever, even beyond the reach of Congress. This alone proves, unequivocally, that the North did not go to war to end slavery or free the slaves.

War measures halfway through the war, such as the Emancipation Proclamation that freed no slaves (and prevented close to a million slaves from achieving their freedom), have nothing to do with why the North went to war in the first place.
