Why did the Mongolians want to kill shi huangdi?

Answer 1

Yes very. They were known as the bane of Christianity as they moved in to eirope on their military campiagns and killed Christians.

Generally, people throughout history have used the term "barbaric" to mean "something different than the way we do things", implying that the "barbaric" way was inferior. Which, of course, was not strictly true.

In that sense, the mongols were "barbaric", because they most certainly were very different than the European cultures of the time.

In the other sense of the word "barbaric", meaning "cruel or brutal", the tactics of the Mongols could certainly be characterized as such. The Mongols were famous for butchering to the last person any city which refused to surrender to it. That is, the Mongol army would arrive at a city, and demand it's surrender. If it refused, and the Mongols later captured the city (which, happend the vast majority of the time), then Mongols would then kill everyone inside. Even if the city surrendered immediately, the typical Mongol response would be to depopulate the city (move everyone out) into the local countryside, raze the entire city to the ground, then sell large portions of the remaining population into slavery, while forcing the rest into agricultural work.
