Final answer:
The Emancipation Proclamation led to many free African-Americans volunteering to fight for the Union and shifted the focus of the Civil War to the struggle for freedom and the end of slavery.
Step-by-step explanation:
An effect of the Emancipation Proclamation was that many free African-Americans volunteered to fight for the Union. This was because the Proclamation declared that enslaved African-Americans in the Confederate states were to be considered free. By joining the Union army, African-Americans could fight for their own freedom and for the end of slavery.
However, it is important to note that the Emancipation Proclamation did not immediately free all enslaved African-Americans in the South. It only applied to the areas that were under Confederate control at the time. It wasn't until the 13th Amendment to the United States Constitution was ratified in 1865 that slavery was officially abolished in the entire country.
The Emancipation Proclamation also had another effect on the South. It shifted the focus of the Civil War and turned it into a struggle for freedom and the end of slavery. This made it more difficult for the Confederacy to gain international support for their cause, as many countries had already abolished slavery.
