How did the definition of war evolve during the Civil War?

The definition of war evolved during the Civil War to encompass military, economic, and political means, reflecting the complex nature of conflicts during that period. The Civil War was not just a series of battles fought with tactics and strategies; it also involved significant economic dimensions, such as the impact on the Southern economy due to the Union blockade and the ability to mobilize resources effectively. Political factors were paramount, as the war was fundamentally about issues like states' rights and slavery, which shaped public sentiment and influenced military outcomes.

This holistic understanding recognizes that war is not merely confined to the battlefield, but involves strategies that include economic warfare, such as blockades and resource deprivation, as well as political maneuvers that seek to sway public opinion and governance. The shift in understanding during the Civil War laid the groundwork for future conflicts, where the integration of different means of warfare became essential in achieving comprehensive victory.
