I need to write the thesis statement of a research paper about United States History: United States & Slavery. 

I also need to write a formal outline for the research paper. Include topics, subtopics, and details so that the reader gains a clear idea of the contents of the paper. Remember to begin with a title and to follow all the formatting rules. 

Lastly I need to list three or more sources that I'm  using for the research paper. At least one should be a print source. Sources must include .gov or .edu domains.

I already cited one  please inlcude the rest:
