The south depended on slaves to help America function economically and it had been that way since the early 1600’s. The sickening thought of owning slaves developed in the North, alongside the fact that mass agricultural work wasn’t needed due to the cold climate. As northern states came to the realization that slavery is morally wrong, any attempt to fully abolish slavery right then and there was a direct threat to the South’s way of living. The fight of states becoming free or slave states gradually progressed and became unbalanced until The Missouri Compromise in 1820, which established the 36′ 30 parallel as a line that would evenly divide free and slave states equally. In 1847, Lewis Cass produced the idea of popular sovereignty, but Senator Stephen Douglas popularized it in the 1850’s. Popular sovereignty is when the citizens of the state get to decide whether it becomes a free or slave state. This idea will mostly contribute to the civil war in the 1860’s by raising tensions and persuading people to fight for what they think is right. The Southerners claimed that slavery drove the economy because slaves didn’t have to be paid, and without the ability to mass produce crops to sell the other countries, America would be in a recession. The Southerners claimed that the idea of owning a slave is morally wrong and that an African-American male should be just as equal as a White male. The spark that ignited the fire was Abraham Lincoln’s election in 1860. His party’s anti-slavery outlook struck fear into many southerners, as Lincoln was most certainly going to abolish slavery and merge the North and South for good. As a result, South Carolina became the first state to secede from the Union along with six other states in 1861 in order to avoid losing the ability to own slaves. The Battle of Fort Sumter in 1861 marked the true breaking point of the tensions between the North and South and was known as the first battle of the Civil War.In conclusion, slavery is wrong and the North had all of the right to fight for slavery’s abolishment, but being a society based on textiles and manufacturing, the North just didn’t understand that slavery fueled the southern economy was able to make crops affordable for everyone.
