response: I have no idea how big a land mass he conquered, but he would often kill civilians on a large scale during his campaigns.
original_response: It really was, though these campaigns were accompanied by huge amounts of killings of civilians so he wasn't the greatest guy.
history: Do you know much about Genghis Khan? hes a really interesting figure. I know that he was the Great Khan, and that he was born in 1162. Oh where did he orginate? Somewhere in china? I'm not sure where he was from, exactly, but he was the founder of the Mongol Empire. How long did his reign last? When did he die off? I don't know either of those answers, but he amassed power by uniting the nomadic tribes in Northeast Asia. So he was basially a raider and conqueror? Exactly, he launched Mongol invasions and conquered the majority of Eurasia. Dang thats quite the accomplishment, so much land he took over.
knowledge: These campaigns were often accompanied by large-scale massacres of the civilian populations – especially in the Khwarazmian and Western Xia controlled lands.
