Alboin, king of the Lombards, entered Italy for the purpose of founding a state. Pavia alone ventured to oppose him. The new conqueror laid siege to it; and that city, after a vigorous resistance of three years, reduced to the last extremity, was forced to surrender at discretion. The conqueror, exasperated by the obstinacy of the defence, had resolved to put all the inhabitants to the sword, but their submission disarmed his vengeance. He entered Pavia, not as a conqueror, but as a pacific king; forbade murder, violation, or pillage, and made that important place the capital of his new empire. THIRD SIEGE, A.D. 774. Two centuries of profound peace had rendered Pavia one of the most flourishing cities of the universe, when it beheld the standards of Didier, king of the Lombards, floating at its gates. This grasping prince, jealous of the power of Pope Adrian, sacked every place belonging to the Pontiff. The holy father fulminated horrible excommunications; but these arms were too weak to stop the usurper, and the Pope had recourse to Charlemagne. That monarch crossed the Alps, combated the enemies of the court of Rome, and made such a carnage of them, that the field of battle took the name of _the Plain of the Dead_. Didier sought refuge in Pavia. He had provided that capital with everything necessary for a long resistance. Charlemagne blockaded it, and left the command of his troops to his uncle Bernard; he then took the road to Rome, where he was received as the liberator of the Holy See. After having made a sojourn there, he returned to his army before Pavia, and pressed the siege so vigorously, that it opened its gates after an heroic defence of six months. Didier, his wife and children, were made prisoners and banished to Liége. Thus finished the kingdom of the Lombards, which had subsisted two hundred and six years. Charlemagne added to the titles of Emperor of the Franks and Patrician of the Romans, that of King of the Lombards. FOURTH SIEGE, A.D. 1524.
