It is in our best interest as well as the North's to attempt to abolish slavery!
Compromise of 1850
Ever since the establishment of the first 13 colonies, the North and South states have always had different and colliding agendas. Their economies both work differently, their political beliefs are far from the same and their overall priorities were not in the same/right place at the time. Like any country with such undeniable tension and division, a civil war was bound to happen eventually.
Fugitive Slave Act (1850)
Get over here Dred and bring that negro son of yours too!
No I escaped and live in a free state now, you can't do this!
It is evident that during and before the Civil War, Northerners and Southerners were beyond loyal to their region of the country (for the most part). Often sacrificing social status or even their lives for what they thought to be a "noble cause." Their differing views on slavery as well as the preservation of the Union led to many rebellions, ultimately resulting in war.
Kansas-Nebraska Act (1854)
We the people of Kansas and Nebraska, will practice our popular sovereignty rights, and prohibit slavery throughout our states!
This agreement between both territories led to major disputes on the issues of popular sovereignty, slave trade and the enforcement of the infamous Fugitive Slave Act. It is obvious now that the South got dealt the better hand in this deal, however, the Union suffered the most after this "transaction." This Compromise alone divided the nation even more on the basis of slavery and sectionalism, which unfortunately called for a war not long after it's enactment.
Election of 1860
As a result of the Compromise of 1850 being passed, to appease the South, Congress enacted this law that allowed slave owners to retrieve run-away slaves EVEN IF they were free and living in free states! This infuriated Northern abolitionists and slaves in all of America. This bill solidified the fate of all slaves at the time which incited a rebellion leading to the Civil War.
The Kansas-Nebraska Act allowed the newly entered states into the union as well as letting them exercise their right to popular sovereignty. This act served to repeal the Missouri Compromise which angered both the North and the South. Specifically the South since both of these new states entered as free states. This new-found hatred fueled the South's reason to begin a civil war.
In this election two Southern Democrats, a Republican and Constitutional Union candidate all fought it out for the presidency. The South's decision to nominate two men for office turned out to be more of a sin than a blessing. Abraham Lincoln won only 40% if the votes and became president. He planned to eliminate slavery entirely and preserve the union. With this agenda Southern states one by one beginning with South Carolina, began to secede from the Union. Their secession not only widened the division between the North and South it also led to a lengthy war.
