Generally we lump them all under World History, although in some cases European history is taught separately. But that's generally at the college level. Much of the teaching comes not in "history" classes per se, but rather in literature, foreign language etc.
Yeah, and those world history courses are (of course) biased all to heck.
I still take offense at how most courses depict the Mongols and Ghengis Khan. They *all* take the Muslim worldview that Ghengis was an unprovoked conquerer and one of the most evil men of all time, when research since the 1600's has shown exactly the opposite.
Of course, they also don't mention WHY Ghengis decided to try to destroy the Muslim world - because they chopped off the head of his *trade* ambassador and good friend for no good reason. I don't know about you, but if someone did that to my friend and I had uncontested control of the most powerful army on the planet, I'd start taking the world apart to get to those responsible and make sure they would never do that again.
