What did president Lincoln freeing all slaves in confederacy?

President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, which declared that all slaves in the Confederate states were to be freed. This executive order aimed to weaken the Confederacy's war effort and bolster the Union's moral cause. While it did not immediately free all enslaved people, it paved the way for the eventual abolition of slavery in the United States and allowed for the enlistment of Black soldiers in the Union Army. The proclamation was a significant turning point in the Civil War and in American history.
