Answer:
Often in things such as Bible verses, folk tales, and other media commonly used in the african-american community during pre-civil war, there is a common theme of freedom, pertaining to the want of it. In stories like "The People Could Fly", those who had been kidnapped from their rightful place and sold into slavery used ancient powers and magic, all allowing them to escape to their ultimate goal of regaining freedom. In other tales, this is also present. However, I don't have the time right now to list them. I will do so asap.
