Battle of Monte Porzio: Holy Roman Empire Destroys the Pope's Army
Imperial forces under Christian of Buch and Rainald of Dassel destroyed a Roman army supporting Pope Alexander III at Monte Porzio, killing thousands of Romans in one of medieval Italy's bloodiest battles. The defeat left Rome virtually defenseless against Emperor Frederick Barbarossa and forced Pope Alexander to flee the city. The imperial victory temporarily broke papal resistance to Barbarossa's authority in Italy, though the conflict between pope and emperor would continue for another decade.
