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

I need to write the thesis statement of the research paper about United States History: United States & Slavery. Be sure to write it in one or two complete sentences.

Also, I 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 your paper. Remember to begin with a title and to follow all the formatting rules. 

Then I need to list three or more sources that I'm using for the United States History: United States & Slavery research paper. At least one should be a print source. Domain sources should only be .edu or .gov.

I already cited one  please inlcude the rest:

WORKS CITED  Africans in America – Immigration. Library of Congress. https://www.loc.gov/teachers/classroommaterials/presentationsandactivities/presentations/immigration/african4.html.

I need the research paper as well.
