One instance of sectionalism began in America in the 1850s. By then, the North and the South were loyal only to their interests, not the interests of the country. One example was the Wilmot Proviso, which proposed an end to slavery in all territory won from Mexico. The bill was defeated and the North and the South continued to argue over the issue of slavery. When Abraham Lincoln was elected President in 1860, the South felt as though their voice no longer mattered in Washington. As a result, South Carolina eventually seceded on December 20th, 1860. Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, and Texas were quick to follow. This led to the American Civil War. . Sectionalism in America Divided the nation into factions by location and economic standing. Slavery was a major contributor to Sectionalism in America. Slavery was a heavily disputed topic and caused a clash in viewpoints of Northerners and Southerners. Sectionalism led to racist ideas formed about different groups of Americans and also was a major contributor to the end of slavery through the Civil war. Sectionalism inflicted the black people the most. The Hispanics only effected minorly.
