Speaking of the Mongols, why is it that leftist historians never mention the fact that the Mongols invaded Europe and slaughtered thousands of Europeans leaving areas of eastern Europe practically depopulated? Or that the Turks and other violent, Islamic hordes conquered large parts of Europe? I guess we know the reasons for that.
For the most part the Mongols conquered territory for the purpose of taxing it or opening it up to trade. The local Mongol populations ended up being quite tiny. Eastern Europeans, as a whole, have no more Eastasian ancestry than Western Europeans and that's mostly from events during the Ice Age.
The big killings were done further South in the Islamic countries where, frankly, none of us care how many Moslems they killed nor what they did with the land.
