Quizplus · Accepted Answer

Some states in the Upper South, such as Virginia and North Carolina, were initially hesitant to secede from the Union. However, after Lincoln called for troops to suppress the growing rebellion in the Lower South, many in the Upper South felt betrayed and believed that he had broken his promise to achieve a peaceful reunion. This led to their decision to secede and join the Confederacy.
