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

The U.S. war between the North and the South refers specifically to the Civil War, which took place from 1861 to 1865. This conflict arose primarily from tensions related to slavery and states' rights, with the Northern states (the Union) opposing the Southern states (the Confederacy) that sought to secede from the Union. The Civil War was a pivotal event in American history, leading to significant social, political, and economic changes.

It marked a critical turning point in the nation's trajectory, leading to the abolition of slavery and the preservation of the Union. Understanding this conflict is fundamental when studying U.S. history, as its consequences continue to shape the social and political landscape of the United States. The other wars mentioned, such as World War I, the Spanish-American War, and the Korean War, involve different contexts and are not characterized by the same North-South division that defines the Civil War.
