The Law Library of Congress features a section about Slavery and Indentured Servants (https://memory.loc.gov/ammem/awhhtml/awlaw3/slavery.html). By studying that category carefully, one is able to understand that slaves were not always of African descent as modern America has been led to believe.
Laws listed there lend credence to recent research by Don Jordan and Michael Walsh in a book called WHITE CARGO. The book has proffered outlandish evidence, but who can say it is false? Have the majority of Americans missed the facts because they were deliberately suppressed in our history books?
The New York Times Sunday Book Review had only favorable comments about the new release—stating in particular that the book uses vast irrefutable documentation (http://www.nytimes.com/2008/04/27/books/review/Lau-t.html).
