The Holy Roman Emperor, Frederick I Barbarossa , achieved glory as a warrior. However, it is very possible that his campaigns were not as harsh as those of the soldiers who accompanied him in his victories . On the contrary, on the battlefield and between combat and combat, the emperor also enjoyed a comfortable and gifted life. To do this he transported with his army a good part of his library, a park of beasts and even a "harem" of kind ladies who made life pleasant for him and the prominent members of his army.
His enemies rightly said that while his troops were fighting on the battlefields, he was fighting another type of combat that was less bloody and much more pleasant.
It's another way to go to war, but only for some.
