Civil War: Repressible or Irrepressible?

Due to the course in which events unraveled in the history of the United States, the Civil War could not have been avoided or repressed. The major causes of the Civil War, as listed below, would inevitably have led to a war due to the rising tensions between the north and the south.
1. Economic and social differences between the North and the South.
Especially with the invention of Eli Whitney's invention of the cotton gin, the south was gearing towards a one crop economy as the north became deversified in their economy.
2. States versus federal rights.
Strong supporters of states rights were the southern states, fearing that the federal government would have the power to abolish slavery. This led to the idea of nullification, which presented the idea of states having the power to rule federal acts unconstitutional. When nullification would not work the states moved towards sucession and therefore the civil war.
3. The fight between slave and non-slave states.
A constant issue, the fight over new territories to be slave or non-slave greatly increased tensions between the north and the south, as shown by "Bleeding Kansas."
4. Growth of the abolition movement.
The Second Great Awakening helped greatly to persuade many to become abolitionists. With the help of the publishing of Harriet Beecher Stowe’s Uncle Tom’s Cabin, the Dred Scott Case, John Brown’s Raid, and the passing of the Fugitive Slave Act, the abolitionist movement gained momentum and the south began to fear this, driving them towards sucession.
5. The election of Abraham Lincoln.
This was "the final straw" as South Carolina threatened to sucede if Lincoln was elected president. As fate would have it, Lincoln won the 1960 election causing S. Caroline to declare their secession, and other southern states followed.
