The battle of antietam affected the focus of the civil war by?

Leading to the Emancipation Proclamation.

The Battle of Antietam was one of the bloodiest in American history. The war was photographed and many letters were sent home of the horrors seen at the battle.

The battle itself was a stalemate but the Union claimed victory. The battle kept Confederate forces in Maryland and prevented the war from entering the Union states. This convinced Lincoln to issue his Emancipation Proclamation which freed slaves in Confederate states. The proclamation was symbolic more than it had any actual effect. It gave the bloody war a moral reason to continue the fight. From that point the war became about unifying the Union--a Union that would be without slavery.

the doctrine of nullification recommended that states living inside the union have the one-sided, inalienable ideal to void any law made by the national government that could be esteemed illegal.

the united states was shaped based on a general agreement among its individual states. hence, it is inferred that under the hypothesis of invalidation, since the states are the establishment of the union, they have the ability to referee and disprove unlawful laws.
