Answer 1

The key political decision made by Abraham Lincoln that helped change the nature of the war in the Union's favor was issuing the Emancipation Proclamation. This proclamation not only aimed to free enslaved people in the Confederate states but also transformed the Civil War into a struggle for freedom, bolstering the Union's moral cause and allowing for the enlistment of black soldiers into the Union Army.
