Fredrick Douglass wrote his own account of life in which he mentioned about the ills of slavery and about the hardships which the slaves had to undergo. He had tried to expose the cruelty of slavery which doesn't spare anyone born in a black family. He points out the idea that a slave is a form of property owned by the master and he possesses full control over him.
