Such was the state of Italy, when the Germanic diet, assembled at Frankfort in 1152, conferred the crown on Frederick Barbarossa, duke of Swabia, and of the house of Hohenstaufen. This prince was nephew to Conrad III, whom he succeeded; he was allied to the two houses of the Guelfs and Ghibellines, which had contended with each other for the empire, and was regarded, with good reason, by the Germans as their most distinguished chief. Frederick Barbarossa was not only brave, but understood the art of war, at least so far as it could be understood in an age so barbarous. He made himself beloved by the soldiers, at the same time that he subjected them to a discipline which others had not yet thought of establishing. He held his word sacred; he abhorred gratuitous cruelty, although the shedding of human blood had in general nothing revolting in it to a prince of the Middle Ages; but the prerogatives of his crown appeared to him sacred rights, which from pride, and even from conscience, he was disposed to preserve and extend. The Italians he considered in a state of revolt against the imperial throne and the German nation, and he believed it to be his first duty to reduce them to subjection. [Illustration: A VENETIAN SOLDIER, TWELFTH CENTURY (Based on Vicellio)] Frederick Barbarossa, accordingly, in the month of October, 1154, entered Italy with a powerful German army, by the valley of Trent. He proposed to himself not only receiving there the crowns of Italy and the empire and reducing to obedience subjects who appeared to him to forget their duty to their sovereign, but also to punish in particular the Milanese for their arrogance, to redress the complaints which the citizens of Pavia and Cremona had brought against them, and to oblige Milan to render to the towns of Lodi and Como, which it had dismantled, all the privileges which Milan itself enjoyed. On arriving at Roncaglia, where the diets of the kingdom of Italy were held, he was assailed by complaints from the bishop and nobles against the towns, as well as by complaints against the Milanese from the consuls of Pavia, of Cremona, of Como, and of Lodi; while those of Crema, of Brescia, of Piacenza, of Asti and Tortona vindicated them. Before giving judgment on the differences submitted to his decision, Frederick announced his intention of judging for himself the state of the country, by visiting in person Piedmont and Montferrat. Having to pass through the Milanese territory on his way to Novara, he commanded the consuls of Milan to supply him with provisions on the road. The towns acknowledged that they owed the emperors upon their journeys the dues designated by the feudal words “_foderum, parata, mansionaticum_” (forage, food, and lodging); but the Germans, retarded in their march by heavy and continued rain, took two days to reach a stage which the Milanese supposed they would reach in one; provisions of course failed; and the Germans avenged themselves on the unhappy inhabitants by
