The connection between sectionalism, slavery, and states' rights as causes of the Civil War can be summarized as follows: The Northern and Southern states had distinct interests and concerns, leading to tensions over economic, social, and political differences. Slavery was a major point of contention, with the South relying on it as an essential part of their economy while the North increasingly opposed it morally. The Southern states argued for states' rights, claiming they had the right to determine their own laws, including those related to slavery. The election of Abraham Lincoln in 1860, who was against slavery's expansion, heightened Southern fears and led to their secession from the Union. The secession was based on the principle of states' rights and the desire to protect slavery, marking the start of the Civil War. reword this
