How did slaves view the civil war ?

Slavery played the central role during the American Civil War. The primary catalyst for secession was slavery, especially Southern political leaders' resistance to attempts by Northern antislavery political forces to block the expansion of slavery into the western territories.

Some slaves were treated well by their owners, while others were treated horribly. They were sometimes beaten, whipped, branded, burned, and imprisoned. Children of slaves were owned by the slave owner. They were often sold to other owners and the parents had no say.
