Ierne L. Plunket, Europe in the Middle Ages
“ Since other people’s possessions were not surrendered without a struggle, even in the Middle Ages, it was fortunate for them that they had the genius to win and hold what they coveted.Pope Leo IX, like his predecessors in the See of Peter ever since Charlemagne had confirmed their right to the lands of the Exarch of Ravenna,6 looked uneasily on invaders of Italy, and he therefore attempted to form a league with both the Emperors of the East and West that should ruin these presumptuous usurpers. ”
