This category is called "historical revisionism" to distinguish it from "alternate histories", which are "what if" scenarios acknowledged by their authors to be fictional.
This category is for sites that discuss theories (recently, most notably promoted by Bernal in "Black Athena" and other publications) that "classical" Greek and Mesopotamian civilizations derived their central ideas from Egypt and therefore from people of an African racial type.
Listed sites may express opinions pro, con, or mixed on any such ideas.
