The cartoon that accompanies the video features everything from gladiator battles, the purpose of Hadrian's Wall and the religious make-up of Roman society.

It also features a series of ethnically diverse characters, which is what appeared to anger the Infowars host, who implied that the BBC didn't care about 'historical accuracy'.
