Uncle Tom
Uncle Tom was the title character of Harriet Beecher Stowe's 1852 novel, Uncle Tom's Cabin. He was a slave who used nonresistance and gave his life to protect others who had escaped from slavery. However, he also came to be seen as inexplicably kind to white slaveholders, which led to the use of Uncle Tom as a derogatory epithet for an exceedingly subservient person.
