The Civil War was sparked by sectionalism, slavery, and states' rights disputes. The North and South disagreed on economic, social, and political matters. Slavery was a major source of conflict, as the South relied on it economically while the North opposed it morally. States' rights also played a role, with the South asserting their right to determine their own laws, including slavery. When Lincoln became president and posed a threat to their lifestyle, Southern states seceded in order to protect their states' rights and slavery. This initiated the beginning of the Civil War.
