U.S. Civil War Map: Union vs. Confederacy States #250362 (License: Personal Use)

The map uses distinct colors to represent political allegiance during the American Civil War: deep blue for free Northern states, yellow for border slave states that remained in the Union (e.g., Kentucky, Missouri), gray for newly admitted Union states like Kansas, and brown for the eleven seceded Confederate states. Nebraska and Dakota Territories are shown in light blue but were not yet states; Kansas’s gray coloring reflects its contested status and late admission in 1861. The visual clearly demarcates the geographic and political split that defined the conflict.
