slavery issue

Whereas the Missouri Compromise and the Compromise of 1850 were created to ameliorate the slavery issue, the Kansas-Nebraska Act was created in the hope of making a Midwestern transcontinental railroad possible. The Missouri Compromise kept the slavery issue at hold for a time until new states were added to the union that offset the sectional balance. After this, the Compromise of 1850 held off the issue for 4 or 5 years even though the north clearly won that battle. After that, the Kansas-Nebraska act was the final straw. As a reaction to this, the purely sectional Republican party was born, which was completely anti-slavery.
