Why is Why did the Emancipation Proclamation only apply to states outside of the Union?

The Emancipation Proclamation was issued by President Abraham Lincoln during the American Civil War on January 1, 1863. It declared that all slaves in Confederate states shall be set free. However, it is important to note that the Emancipation Proclamation only applied to states that had seceded from the Union and were actively participating in the rebellion against the United States. There are several reasons for this limitation:

1. Legal and Constitutional Constraints: President Lincoln issued the Emancipation Proclamation as a war measure, relying on his authority as Commander-in-Chief during the wartime. Since the proclamation was based on the President's powers as a military commander, it was limited in its application to areas of rebellion (Confederate states). The Constitution protected slavery within the states that remained loyal to the Union.

2. Practical Considerations: The Emancipation Proclamation aimed to undermine the economy and military capability of the Confederacy, while also offering a moral critique of slavery. By declaring slaves in Confederate-held territories as free, Lincoln hoped to weaken the Confederacy economically and encourage enslaved individuals to escape or rebel against their owners. Applying the Emancipation Proclamation to states within the Union would have been impractical, as it could have sustained sentiments of disunion among states that were already divided on the issue of slavery.

3. Political Strategy: Lincoln understood that the Union consisted of both slaveholding states and states that had abolished slavery. He was aware that implementing the Emancipation Proclamation across the entire Union may have jeopardized public support for the Union cause, particularly in the border states such as Kentucky, Missouri, and Maryland, where slavery still existed. Lincoln was strategically navigating the issue of slavery to seek unity and support among a diverse population.

4. Diplomatic Considerations: By limiting the Emancipation Proclamation to Confederate states, Lincoln also managed to shape the international perception of the war. The proclamation effectively turned the Civil War into a battle over slavery rather than just a conflict to preserve the Union. It discouraged European powers, such as Britain and France, from recognizing the Confederacy or intervening on its behalf, as both countries had abolished slavery and public sentiment supported the Union's cause.

Overall, the Emancipation Proclamation's limited application served to target the institution of slavery in Confederate states, weaken the Confederacy's economy and military, while also navigating the complex political and constitutional dynamics within the Union.
