This is a hard question to answer. In terms of sheer evil grisly brutality, combined
with the amount of humans slaughtered and the many nascent city states that
were obliterated off the face the earth, it would be the mongol empire. I realize
they are not European but they deserve the top spot.
In terms of misery that cursed humanity and sheer number of lives extinguished.
The muslims were excellent at civilization erasing also. We are getting closer to

Ukraine to the gulag archipelago… possibly 100 million killed and hundreds of
millions plunged into a fate of living dead. When the russion army was advancing
towards germany in the final months of WW2 the savagery and brutality of the women

people from the nazis.
Next come the Chinese.
Now we could mention the british.
Before I go, I have to give honorable mention to trump! Who’s tweets were so evil
