Which document gave enslaved people their freedom in 1863?

The document that granted freedom to enslaved people in 1863 was the Emancipation Proclamation. Issued by President Abraham Lincoln on January 1, 1863, it declared that all enslaved people in Confederate-held territory were to be set free. While it did not immediately free all enslaved individuals, it was a significant step towards the abolition of slavery and paved the way for the eventual passage of the 13th Amendment.
