How is the Emancipation Proclamation different from the 13th Amendment?

The Emancipation Proclamation was issued by President Abraham Lincoln in 1863 during the Civil War and declared that all slaves in the Confederate states "shall be then, thenceforward, and forever free." However, it only applied to states in rebellion and did not have the force of law. The 13th Amendment, on the other hand, was passed by Congress in 1865 and abolished slavery and involuntary servitude throughout the United States, including the border states that had remained in the Union during the Civil War. It was ratified by the required number of states later that year and became a part of the Constitution. In short, the Emancipation Proclamation was a wartime measure that only applied to certain states, while the 13th Amendment was a permanent constitutional amendment that ended slavery and forced labor in the entire country.
