Answer :
From the earliest days of the Civil War, slaves had acted to secure their own freedom. The Emancipation Proclamation confirmed his insistence that the war for the Union must become a war for freedom.
It added moral force to the Union cause and strengthened it both militarily and politically. The Emancipation Proclamation was an executive order issued by Abraham Lincoln on January 1, 1863. It proclaimed the freedom of slaves in the ten Confederate states still in rebellion. He also decreed that freed slaves could enlist in the Union Army, thus increasing the Union's available manpower. Black Americans were allowed to serve in the Union Army for the first time, and nearly 200,000 would do so by the end of the war. Finally, the Emancipation Proclamation paved the way for the permanent abolition of slavery in the United States.
