What was one of the major outcomes of the Civil War in the United States?

The preservation of the Union was one of the major outcomes of the Civil War in the United States. This conflict ultimately determined that the nation would remain united, rather than allowing the Southern states to secede and form an independent Confederacy. The outcome signified a reaffirmation of the principles of national unity and democracy, ensuring that the federal government held authority over the states.

Additionally, this outcome had significant implications for the future of the United States, leading to the dissolution of secessionist notions and reinforcing the idea of a single nation. The result of the war also set the stage for significant social and political changes, including the abolition of slavery, which further helped to unify the country under a common set of rights and freedoms.
