Emancipation Proclamation
Definition
An executive order issued by President Abraham Lincoln on January 1, 1863, declaring slaves in Confederate states to be free.
Explanation
The Emancipation Proclamation was one of President Abraham Lincoln's most significant actions during the Civil War. It declared that all slaves in the states that had seceded from the Union were to be set free. The proclamation became effective on January 1, 1863, and applied only to slaves in states still in rebellion against the United States, not to slaves in Border States that had remained in the Union. The Emancipation Proclamation reframed the Civil War as a struggle not only for union but also for human freedom. It paved the way for the Thirteenth Amendment, which completely abolished slavery throughout the United States. The proclamation demonstrated the President's power to take executive action during wartime and is considered one of the most important documents in American history.
