During the late schism, Tivoli had sided with Anacletus, and on his death still refused to acknowledge Innocent. A Roman army was accordingly marched out to reduce the place to obedience, but was defeated by a sudden sally of the besieged. A fresh army which was shortly raised behaved better, and Tivoli was reduced. Burning with shame at the disgraceful failure of their first attempt, the Romans clamoured for the total destruction of a hated rival and the dispersion of its inhabitants. But the pope, satisfied with the triumph of his authority, would lend no countenance to so guilty a severity, and concluded with his chastised children a fatherly peace. For thus checking the bad passions of his subjects, he incurred their displeasure; whereupon, the republican leaders, perceiving their opportunity seized it at once, and, by their virulent denunciations to the mob of the pretended tyranny of priests, soon stirred up an insurrection; and got the citizens to hold a congress in the Capitol, at which the papal government was declared at an end, and the ancient republic restored. Innocent strove to counteract this revolution, and called a synod at the Lateran; before which he protested against any right of the laity to interfere with his government, much less to alter it. But his efforts were vain; and he took his ill-fortune so much to heart that he sickened and died of grief. Celestine II., his successor, had, as papal legate in France, formerly befriended Arnold of Brescia: a circumstance that could not fail to make him popular, and conduce to give effect to his efforts at conciliation; so that he completely succeeded in allaying the revolutionary storm during his short reign, which his death terminated in the spring of the following year. Under Lucius II., who was next elected to the papal throne, the public disorders burst forth again in an aggravated degree. Lucius deeply offended the Romans by seeking to secure himself against their fickle loyalty in an alliance with Roger, the Norman king of Sicily. In resentment of this proceeding, the newly elected senate first caused the strongholds of the Frangipani, and of other adherents of the papal party within the city, to be demolished, and then sent an embassy to Conrad III. of Germany to invite him to come and assume the imperial crown under their auspices, and act as counter-check to the king of Sicily. But Conrad, mistrusting the high-flown letter containing the invitation, and feeling moreover little sympathy with rebels against the pope, declined it. Hereupon, Lucius thought it the proper time to strike a blow towards recovering his authority. To this end he marshalled his cardinals and other dignitaries in all their pomp; put himself at their head, and, escorted by an armed array of lay partisans, set out for Rome with the intention of besieging the Capitol.
