By freeing all slaves in the Northern states, Lincoln allowed thousands of African Americans from the North to serve as soldiers in the Union Army.
Explanation:
- President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863. It freed all slaves who lived in the Confederacy during the Civil War.
- Since the southern states seceded from the Union, the proclamation originally had very little effect other than guaranteeing freedom to any slave who managed to escape to the northern states.
