Answer :
And upon this act, sincerely believed to be an act of justice, warranted by the Constitution, upon military necessity, I invoke the considerate judgment of mankind, and the gracious favor of Almighty God, " Lincoln said.
Lincoln had proposed the Proclamation on September 22, 1862. In what became known as the preliminary Emanication Proclamation, Lincoln made it clear, and in public, to the Confederate states that if they didn't return to the Union by January 1 , 1863, the President would issue a proclamation freeing slaves in those rebellious territories.
Lincoln was persuaded by secretary of state William Seward to wait until the Union had won a significant battlefield victory. The Union forces had just repulsed an attack by General Robert E.Lee's forces at the battle of Antietam , which Lincoln saw as the sign that the time had came for the Proclamation.
President Lincoln had given the states in rebellion approximately three months notice to lay down the arms and give up their desire for a separation nation.
