What was the U.S. war between the North and the South called?

The U.S. war between the North and the South is referred to as the Civil War. This conflict took place from 1861 to 1865 and primarily revolved around issues such as states' rights and slavery. The war was characterized by significant battles between the Union (the Northern states) and the Confederacy (the Southern states), leading to profound social, economic, and political changes in the United States.

The other wars listed, such as the Revolutionary War, which was fought for American independence from British rule, World War I, a global conflict primarily involving European nations, and the Spanish-American War, which involved U.S. intervention in Cuba and the Philippines, are entirely different in context, causes, and outcomes. The Civil War stands out as a pivotal moment in American history, addressing internal divisions rather than foreign conflicts.
