3 strong main causes of the civil war

Slavery, Economic and Social difference, and Federal rights.

Explanation:

While there were many political and cultural differences between the North and the South that contributed to the American Civil War, the main cause of the war was slavery. Below we will discuss the impact slavery had in leading up to the war as well as some of the differences between the two sides that led to such a great divide. Slavery At the heart of the divide between the North and the South was slavery. The South relied on slavery for labor to work the fields. Many people in the North believed that slavery was wrong and evil. These people were called abolitionists. They wanted slavery to be illegal throughout the United States. Abolitionists such as Frederick Douglass, John Brown, Harriet Tubman, and Harriet Beecher Stowe began to convince more and more people of the evil of slavery. This made wealthy landowners in the South fearful that their way of life would come to an end. States' Rights The idea of states' rights was not new to the Civil War. Since the Constitution was first written there had been arguments about how much power the states should have versus how much power the federal government should have. The southern states felt that the federal government was taking away their rights and powers. Expansion As the United States continued to expand westward, each new state added to the country shifted the power between the North and the South. Southern states began to fear they would lose so much power that they would lose all their rights. Each new state became a battleground between the two sides for power. Industry vs. Farming In the mid-1800s, the economies of many northern states had moved away from farming to industry. A lot of people in the North worked and lived in large cities like New York, Philadelphia, and Boston. The southern states, however, had maintained a large farming economy and this economy was based on slave labor. While the North no longer needed slaves, the South relied heavily upon slaves for their way of life
