How many enslaved african americans did the emancipation proclamation immediately free?

a. none
b. all enslaved people living in the states of the union
c. all enslaved people living in western territories
d. about 280,000 african american men, who joined the union army

The correct answer is A) none.

None enslaved African Americans were immediately freed by the  Emancipation Proclamation.

Indeed, President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, and the Civil War ended until 1865. So there were no immediately slaves freed after the Emancipation Proclamation. Lincoln wanted to make the announcement after a solid battle victory during the war in order to get the public support. That is why waited after the Battle of Antietam of September 17, 1962. One of the main effects of the proclamation was that black people could enlist into the Union army. Probably some 200, 000 African American.
