Background information:
Frederick Douglass was a slave who was born in Tuckahoe, Maryland. He experienced many brutal conditions as a slave and escaped to be able to write his autobiography in 1845, Narrative of the Life of Frederick Douglass to reveal the horrors of slavery.

Thesis Statement:
Along with the use of the many different types of figurative language, Douglass uses his life story to unveil the effects of slavery on slaves as well as slaveowners, which supports his position to end slavery.
