"The newer ones are too PC to admit to the notion that Muslims tried to pillage and conquer Europe other than Spain."
And they completely fail to mention the success of the Khan's Golden Horde invasion of the 1300s that had the Khan knocking on the gates of Vienna after thoroughly whipping the butts of the European Christian armies.
True, but the Mongols aren't Muslim.
Only after their empire broke up into different Khanate's did some convert to Islam.
After all, if they all converted to Islam, it would really be difficult to explain how come the modern Mongols are Buddhist.
