Step-by-step explanation:
The Emancipation Proclamation was signed on January 1, 1863, by United States President Abraham Lincoln. It was signed during the American Civil War and declared that all slaves in Confederate-controlled territory were to be set free. The main reason for the Emancipation Proclamation was to weaken the Confederacy's ability to continue the war by removing a significant portion of their labor force. It was also a symbolic gesture that demonstrated the Union's commitment to ending slavery in America.
