ABSTRACT
The treaty of Constance between Emperor and Pope had been of short duration. Its terms satisfied the immediate requirements of both parties, but neither was able to fulfil them, and the consequent breach of the treaty by both sides gave rise to considerable ill feeling. With the surrender of Milan the purpose of the military expedition was achieved and most of the troops were allowed to return home. The Emperor himself proceeded to Roncaglia, where he held a diet in November to settle the future government of the Italian kingdom and the relations of the cities with their sovereign. Frederick had dismissed the greater part of his army before the diet at Roncaglia, and the decrees of that diet seemed to him so obviously just and reasonable that apparently he anticipated no trouble in their execution. Frederick had certainly intended to march on Rome, but the escape of the Pope frustrated his purpose.
