Ineed an answer as soon as possible.

use the attached image.

1) by what authority did lincoln issue the emancipation proclamation?

2) what enslaved people does the emancipation proclamation free? what people does it not free?

3) in what way does the thirteenth amendment expand on the emancipation proclamation?

4) why do you think lincoln chose not to free all enslaved persons with the emancipation proclamation?

(1) Executive power of "necessary and proper"--Lincoln was able to legislate from the Oval by use of executive order and in this case as Commander in Chief of the army. Lincoln used the Emancipation Proclamation as a means to control the message of the Civil War, boost morale, and target the Southern labor force.

(2) President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, as the country moved toward its third year of the wicked common war. The announcement proclaimed "that all people held as slaves" inside the defiant states are, and henceforward might be free."

(3) Lincoln recognized that the Emancipation Proclamation would have to be followed by a constitutional amendment in order to guarantee the abolishment of slavery. The 13th amendment was passed at the end of the Civil War before the Southern states had been restored to the Union and should have easily passed the Congress.

(4) On September 22, 1862, Lincoln announced publicly that he would issue the Emancipation Proclamation as encouraged by the Union victory at Antietam. Emancipation Proclamation is a decree freeing all enslaved persons after January 1, 1863, in the states still in rebellion. Enslaved African Americans were freed by the Proclamation only in the states which had war with the Union. It did not free slaves in the border states. The proclamation changed the dispute over preserving the Union into a war of liberation.

Hope this helps you :) =)
