As many Americans began to move north from the expansion of land, the same issues that were once present for them came along with them as the Kansas-Nebraska Act began
All types of people embarked on a journey to Kansas and Nebraska for many reasons, with some hoping to spread positivity, and others bring the same behavior from the south and nort to the center
because of this, popular sovereignty became the main factor in the cause of the event since debates for and agains slavery began
This led to a divide between democrats and republicans on the decisionmaking towards having these states become either free or slave territories. Because of this, many people began to migrate to the states to state their opinions.
