chair. At length, in
1073, on the death of Alexander, Hildebrand was himself as it were compelled by the tumultuous demands of the mob to accept the vacant tiara (
22d April); but he refused to receive consecration until the sanction of the emperor had been obtained. This did not arrive for more than a
month, although meanwhile he had been practically exercising many of the papal functions; finally, however, he was ordained to the priesthood, and some
days afterwards (
30th June) solemnly consecrated pope by the title of
Gregory VII., a name which he chose in testimony of his veneration for the memory and character of his earliest patron,
Gregory VI.[1] Once firmly established on the papal throne, Gregory lost no
time in giving the utmost possible practical effect to the two leading ideas of his life, the establishment of the supremacy of the papacy within the church, and the effective assertion of the supremacy of the church over the state. In March
1074 a synod was held in Rome which condemned the simony that had grown so prevalent throughout the church, and also enacted the old stringent laws of celibacy which had become almost a dead letter, especially in Germany and in the north of Italy; simoniacal or married priests were declared to be deposed and their priestly functions invalid. The resistance of the clergy to these decrees was utterly in vain; papal legates visited every country, and, supported by the popular voice, compelled submission. At a second synod held in Rome in February
1075 the decrees of the first were confirmed, and the first blow was struck which afterwards resulted in the long protracted wars of investitures. At that synod it was determined that any ecclesiastic who in future should accept office from the hands of a layman incurred the penalty of deposition, while the secular lord who bestowed investiture was to be excommunicated. The decree was aimed immediately at certain German bishops, Henry's personal advisors, but hardly less directly at Henry himself. The emperor, finding his hands at the moment fully occupied with the suppression of a revolt among the Saxons, was politic enough to conceal his resentment for the
time, and to dismiss his advisers; but as soon as the war had been brought to a close, his defiance found ample expression. Meanwhile Gregory was not unopposed even in Italy, and during the Christmas festivities of
1075 a revolt in Rome itself was organized by Cencius, who had placed himself at the head of those nobles who were opposed to reform; the pope, however, had the popular enthusiasm on his side, and ultimately the insurgents were compelled to fly. A papal embassy was next sent, early in
1076, to Henry at Goslar, citing him to appear personally at Rome at a council to be held in the second
week of Lent, and there answer for his simony, sacrilege, and oppression. Henry's rage at this knew no bounds; he dismissed the legates with insult, and at a diet held at Worms (
24th January
1076) replied by declaring Gregory deposed on charges of tyranny, magic, and
adultery, by sending notification of this fact to the Roman clergy, and by taking steps for appointing a successor to the dethroned pontiff. Gregory now lost no time in excommunicating all the bishops who had attended the diet of Worms, in solemnly deposing and excommunicating the emperor, and in
absolving his subjects from their oath of allegiance (
22d February
1076). This counter action produced a powerful effect upon the German princes and people, many of whom had had good cause to resent Henry's tyrannies; one by one the bishops who had announced their withdrawal from Gregory's obedience now signified their contrition, and at a diet held at Tribur (September
1076) the
election of a new
emperor began to be discussed. Resistance being in the meantime impossible, Henry resolved upon humbling himself to the utmost; in the dead of winter he set out to make his submission; Gregory was in waiting for him at Canossa, where (
25th to
27th January
1077) that famous penance which Europe has not yet forgotten was imposed (see
vol. x.
p. 488).
Absolved only on condition of his not assuming the royal dignity till his case had been investigated and decided, Henry had no sooner left the papal presence than he began to plot his revenge. Throwing himself upon the generosity of his Lombard vassals, he took courage to face the papal excommunication which was renewed in November
1078; and in the wars which ensued his arms were finally successful. Rudolf of Swabia having died soon after the battle of Merseburg in
1080, the emperor proceeded with a powerful army to escort into Italy Guibert of Ravenna, who had been chosen at Brixen (June
1080) as Gregory's successor. In three successive summers the attack on Rome was renewed, but it was not until
1084 (March 21) that the treachery of some of the nobles of the city opened the gate to the invader. Gregory was now at last compelled to take refuge in the castle of
St Angelo, while Guibert was established on the pontifical throne as his successor with the title of
Clement III. After receiving coronation from Clement, Henry determined to return at once to Germany, especially as Robert Guiscard was known to be approaching. Released accordingly by the arrival of the Norman duke, Gregory excommunicated once more both Henry and Clement; but not deeming himself secure at Rome, where he had reason to know that his power was no longer what it once had been, he in May
1084 placed himself under Robert's protection at Salerno, where he died, May 25,
1085, after a comparatively brief pontificate of not much more than ten years. His last words are reported to have been, “I have loved righteousness and hated iniquity, and therefore I die in exile.” His festival (duplex) is observed throughout the Roman Church on the anniversary of his death. His successor was
Victor III.
Unlike Gregory the Great, Hildebrand was no author; his literary remains are all comprised in eleven books or “Registers” of letters, which have often been printed. The XXVII dictatus often attributed to him are not now regarded as genuine. Among the numerous earlier biographies may be mentioned those of Paul of Bernriet, Pandulf of Pisa, Nicolas of Aragon, and Cardinal Bruno; among later monographs the most important are those of Voigt (Hildebrand als Gregor VII. u. sein Zeitalter, 1815; 2d ed. 1846; French translation, with introduction and notes, by Jager, 1834; 4th ed. 1854), Bowden (The Life and Pontificate of Gregory VII., 1840), Söltl (Gregor VII., 1847), Helfenstein (Gregor's VII. Bestrebungen nach den Streitschriften seiner Zeit, 1856), Gfrörer (Papst Gregor VII. u. sein Zeitalter, 7 vols., 1859-61), Villemain (Histoire de Gregoire VII., 1873; English translation by Brockley, 1874), Langeron (Gregoire VII. et les origines de la politique ultramontane, 1874), and Meltzer (Gregor VII. u. die Bischofswahlen,1876). The events of the period are also very fully treated by W. Giesebrecht in his Geschichte der deutschen Kaiserzeit, and in other works. For the epistles, see S. Gregorii VII. epistolæ et diplomatica pontificia, acc. vita ejusdem pontificis et appendices amplissimæ veterum et recentiorum monumenta perplurima Gregorii VII. apologetica complectentes (1877).
