Civil War Causes: States Rights or Slavery — Reading Comprehension

The causes of the American Civil War remain debated by historians, but two major factors are often highlighted: states' rights and slavery. In the first half of the 1800s, the United States became increasingly divided between the North and the South. These regions held deeply different economic interests and social systems. The North favored industrial development and, over time, increasingly opposed slavery. The South, however, depended heavily on enslaved labor for its agricultural economy, especially in growing cotton and tobacco.

The issue of sovereignty—the right of each state to govern itself—was at the heart of many arguments. Southern leaders claimed that the federal government had no authority to interfere with their way of life, including the institution of slavery. They believed the U.S. Constitution protected their rights as independent states. As John C. Calhoun, a prominent Southern senator, wrote in 1837: "The peculiar institution [of slavery] is a positive good." Calhoun's words show how some Southerners justified slavery as essential, not only to their economy but to their society.

Meanwhile, many Northerners considered slavery morally wrong and wanted to prevent its expansion into new western territories. This led to fierce debates in Congress and the country. Compromises, such as the Missouri Compromise of 1820 and the Compromise of 1850, attempted to balance the interests of free and slave states. However, these agreements only provided temporary solutions. As the nation expanded westward, each new territory raised the question: Should slavery be allowed here?

Contradictions appeared even within the idea of states' rights. For example, Southern leaders wanted strong state power when it protected slavery but demanded federal enforcement of the Fugitive Slave Act, which required Northern states to return escaped enslaved people. This revealed a complex relationship between states and the federal government, with each side using the principle of states' rights when it benefited their cause.

The debate over slavery and states' rights grew more intense in the 1850s. The publication of "Uncle Tom's Cabin" and the violent conflict in Kansas, known as "Bleeding Kansas," increased tensions. Some Southerners felt threatened by growing Northern opposition and worried that their political power was slipping away. In 1860, Abraham Lincoln was elected president without winning any Southern states. Southern leaders saw this as proof that the federal government would act against their interests. In response, eleven Southern states decided to secede, or break away, from the Union.

While both sectionalism—loyalty to one’s own region—and disputes over states' rights shaped the conflict, the evidence shows that the expansion and preservation of slavery was the central issue. Most declarations of secession written by Southern states directly mention slavery as their main reason for leaving the Union. The Northern point of view, however, often focused on preserving the nation and stopping the spread of slavery, rather than abolishing it everywhere at first.

In summary, the Civil War was caused by a combination of factors. Arguments over states' rights provided a framework, but the survival of slavery was the most important cause, as demonstrated by speeches, laws, and official documents from the era. Understanding these complexities helps us see why the Civil War was such a significant and tragic turning point in American history.
