Why was the emancipation proclamation important to the civil war?
It officially turned the war into a crusade against slavery. After that, free nations abroad could not support the Confederates without looking pro-slavery themselves.
The Emancipation Proclamation was issued to end slavery. It was issued by Abraham Lincoln, which eventually led to the end of the Civil War. However, the Emancipation Proclamation did not end slavery in all states. It banned slavery in all states but the border states. After the Civil War, Congress created the 13th Amendment, which abolished slavery.
