How slavery was the reason behind the Civil War?

Slavery was a major reason behind the Civil War because the Northern and Southern states had opposing views on it. The North shunned slavery, considering it a blot on the nation, while the South relied on slaves for their cotton, tobacco, and sugarcane plantations. The Anti-Slavery Movement of 1840 threatened the Southern economy, and public opinion in the North, intensified by Harriet Beecher Stowe's novel Uncle Tom’s Cabin (1852), strongly opposed slavery. These economic and moral differences created such tension that a Civil War became inevitable.
