The idea of popular sovereignty is historically significant because it helped to lead to the Civil War.

In historical terms, popular sovereignty refers to the idea that each territory could decide for itself whether it wanted to have slaves or not.  That gave the people (thus the word “popular”) the power to decide for themselves rather than being told what to do (sovereignty).

This may seem like a good idea.  However, it upset policies that had already been created and more or less accepted by both the North and the South.  The idea of popular sovereignty was first put forth in the Kansas-Nebraska Act.  This act gave these two territories popular sovereignty even though the Missouri Compromise had said they would not be able to have slaves.  This meant that the issue was reopened.  When the issue was reopened, violence erupted as both sides tried to ensure that they would win the vote over whether to have slavery.   This violence, often called “Bleeding Kansas,” helped to make the North and South more angry at one another and, thus, to bring on the Civil War.
