Which major event was addressed by the Emancipation Proclamation?

The Emancipation Proclamation was a pivotal document issued by President Abraham Lincoln during the American Civil War, specifically aimed at addressing the issue of slavery in the Confederate states. By declaring that all enslaved people in the states that were in rebellion against the Union were to be set free, Lincoln not only aimed to weaken the South's war efforts but also shifted the moral focus of the war towards the abolition of slavery.
