An example of sectionalism would be during the pre-Civil War era in the United States when there was a growing divide between the Northern and Southern states over issues such as slavery and states' rights. The North was becoming increasingly industrialized and urbanized, while the South was mainly agricultural and relied heavily on slave labor. This led to conflicts and tensions between the two regions, as each believed that their way of life was superior and that they deserved more power and influence in government. This sectionalism ultimately contributed to the outbreak of the Civil War.
