From “Conflict Between the North and South” Three million soldiers fought in the Civil War. Of those, 180,000 were African Americans fighting for the North.

The North and the South had different beliefs about slavery. These beliefs were based on differences in their economies. The economy of a region is the way most people in that area earn their money . . .

The South’s economy was based on agriculture, or growing plants. The most important farms in the South were plantations. These were large farms that grew cotton and tobacco. Plantation owners depended on slaves to take care of their huge crops.

Many people in the North did not believe in slavery. They thought the people of the South should not own slaves. Although some Southerners opposed slavery, most believed they needed slaves for their plantations. They said that ending slavery would be a threat to their economy.

Crops, such as cotton, were picked by slave labor on the Southern plantations in the 1800s.

African Americans made up the majority of people who fought in the Civil War.

The differences between views on slavery was one of the major causes of the Civil War.
