One big similarity is that they both were in the same area they dealt with the same terrain and they also lived in the same culture as each other they were quite similar despite being two different cultures.
The two main areas that led to disagreement before the Civil War would include the dispute over slavery and the argument over states' rights.
With the dispute over slavery, some states, especially in the North, believed the institution of slavery was morally wrong and wanted to stop slavery from spreading to expanding territories or areas.
That's why in the Compromise of 1850, California became a free state and slave trade was banned in Washington, D.C. because of all the support going against slavery.
This terrible practice of slavery was talked about in books like <em>Uncle Tom's Cabin</em> by Harriet Beecher Stowe, and also was spoken out by famous abolitionists like Frederick Douglass and others.
People in the Southern states believed slavery was part of their lifestyle, culture, and economy, and argued that it needed to thrive to keep the South going.
They wanted slavery to expand to territories and other states, like the argument of pushing slavery to go to Missouri.
The South also believed that their individual state should have more power over the federal government and that they should have the right to get rid of federal laws if needed. The South was not in favor of Abraham Lincoln keeping the country together when they were very divided on the issue of slavery as well as some government laws.
The North believed that the Union or country should stay together and that the federal government should have more power than the individual states.

Lincoln worried about resupplying fort Sumter because he thought it would provoke war (which it did), since the Southerners would view this as a federal intrusion.
