Your crusades were as all covering political, and not achieved by religions. Your religions are often holding oneself as better, when others are observed as more wrongful, which is not although always holding good. So, the Viking areas as well have been conquered with crusades, so that they would not do raiding more than they did. The meaning of crusades was to sanctify the Europeans to feel themselves as better towards the rest of the world, which eased their controlling to do matters meaningful to the Creator as well. Crusades did tales also later, when we observe those as meaningful also in later times, while causing so super emotions, that angels in Heaven as well were as if accomplishing their functions, which very little was the reality, because no one is more holy than the other as a soulful entity, but only humans’ different cultures were the cause of crusades.
