What major conflict was fought over the issue of states’ rights and slavery?

The Civil War is recognized as the major conflict fought primarily over the issues of states’ rights and slavery in the United States. Tensions had been escalating between the Northern states, which were generally anti-slavery, and the Southern states, which supported the institution of slavery. The Southern states argued that they had the right to govern themselves and make their own laws, including those regarding slavery. This clash of perspectives ultimately culminated in secession from the Union by several Southern states and the outbreak of war in 1861.

The significance of this conflict is rooted in its examination of federal authority versus states’ rights, with slavery acting as a central flashpoint. The war resulted in a redefinition of the relationship between state and federal powers, especially through the eventual passage of amendments aimed at abolishing slavery and granting citizenship and voting rights to African Americans. This lasting impact solidifies the Civil War’s place in history as a pivotal moment concerning issues of civil rights and governance in the United States.

In contrast, the Revolutionary War focused on independence from British rule, the War of 1812 involved conflicts over trade and warfare with Britain, and World War I centered on global alliances and conflicts rather than domestic issues regarding states' rights and slavery.
