Sectionalism didn't really affect the War of 1812; it was an outcome of the war. The controversy over the statehood for Missouri, which had attracted many Southerners who expected to use slaves to grow cotton and hemp, upset Northerners. The North accused the South of conspiring to extend slavery, while the South believed the North was conspiring to destroy the Union and slavery. Virtually every issue that would wrack the Union in the next forty years was present in the Missouri controversy. This is the beginning of the separation that would lead to the Civil War.
