Answer 1

Answer 2

States fighting the United States.

Step-by-step explanation:

The Emancipation Proclamation was a document that granted liberty to more than 3.5 million slaves. The Proclamation ordered the liberty of slaves in ten states, or the ones that were in rebellion. Because it was issued under the president's authority to suppress rebellion, it necessarily excluded areas not in rebellion. The Proclamation was issued in January 1863.
