The first symbol is the North for freedom and South for slavery. When the North is described it is used to show freedom, like when Eliza escaped north or when the Quakers took in Eliza's entire family. The south represents slavery, which is where Tom and the other slaves live their miserable lives.
The next symbol is Uncle Tom. He is used to show people what a good, honest, and hard working man truly is like. He symbolizes the themes of hope, faith, love, and persistence and is a great example of all the stories themes.
My last symbol is Eva. She is used to symbolize how to not be a stereotype. Since she is from the big racist area south, she is expected to have no respect for black people and treat them like dirt. She prevails from the stereotype and is a great character that is not racist at all. In conclusion all the symbols I have chosen have great value towards the story and how to live your life.
