Answer:
End slavery
Explanation:
The Emancipation Proclamation was a document signed by president Abe Lincoln that said that slavery was now illegal in the Confederate States of America. Even though it did not technically free any slaves, as the Confederate States largely ignored this, it did make the purpose of the Civil War to end the institution of slavery within the US instead of focusing on just preserving the Union.
