What is known as the bloodiest war in U.S. history?

The Civil War is recognized as the bloodiest war in U.S. history, primarily due to the staggering number of casualties it produced. Estimates suggest that around 620,000 to 750,000 soldiers died as a result of combat, disease, and other war-related causes. This number represents a significant portion of the U.S. population at the time, making this conflict particularly devastating.

The war not only inflicted heavy losses on the military but also had a profound impact on American society, with families and communities torn apart by the conflict. Its legacy persists in various ways, including cultural memory, historical commemorations, and the ongoing discussions around its causes and consequences.

In contrast, while World War I, World War II, and the Vietnam War also involved significant losses, their casualty counts—though high—do not surpass those of the Civil War when considered in the context of the total population and the percentage of the population affected. This distinction solidifies the Civil War's place in history as the most lethal conflict in the United States.
