Compared to rebels in the rest of world history's civil wars, the rebels of the defeated Confederacy were treated very harshly.

Rebels

Civil Wars

Conflicts between groups within the same country or state, often over political, social, or ethnic differences.

Confederacy

A union of states or groups united for a common purpose, often used to refer to the 11 southern states that seceded from the United States in 1861-1865.
