Just read a graphic adaptation of “Lies My Teacher Told Me: Everything Your American History Textbook Got Wrong”, a 1995 book by James W. Loewen that critically examines twelve popular American high school history textbooks.
First themes are lies about the discovery of America by Europeans, who was there, and how it lived, first steps of colonization, about the reasons of Secession War.
Other themes are about what is untold, about segregation, about racism and anti racism, about Vietnam war.
And it also presents why such lies, theirs consequences, and who has something to earn from them.
