Cause, it most likely started by making root histories. Example in like world history they only highlighted the history from Europe and surrounding countries. In American history they highlighted the history from the ones that came over from Europe.
What they failed to do is recognize other culures, like African-American history, Mexican American history, or Asian history. (Sorry if I missed anyone) And now all of these histories are available.
It would be almost impossible but it would be wonderful if someone would put all those different histories into the world and or American history. That way you get a broad idea of what people had to do, what they lived through, their accomplishments in society, or to the world. This would stop the stereotypes, and lies we are told regarding other races, and or cultures. It would certainly bridge many gaps that we see in the world today. It would also help all of us to know each other better.
