Because of the bloodiest battle in the US History, Lincoln was able to issue the Emancipation Proclamation, which helped prevent France and Britain to recognize the Confederacy.
Explanation:
The battle of Antietam is know today as the bloodiest day in the history of the United States of America. It is calculated that there was a total of 22,717 dead, wounded, or missing in consequence of that battle. Somehow the Union was considered the winner, even though their losses weren't that different, giving Lincoln the perfect moment to write an executive order.
The United States experienced phenomenal economic growth. The war brought the return of prosperity, and in the postwar period the United States consolidated its position as the world's richest country.
The Confederate soldiers were called rebels because they were against the ideals and government of the North [or the Union], and they wanted their own way of life and governmental ideals.
