Pope Gregory VII

Hildebrand was born around 1020 in Sovana, a small hill town in the southern part of Tuscany ^[1]. Almost nothing certain survives about his parents. Later tradition made his father a craftsman or smallholder named Bonizo, and the family's modest standing is one of the few points on which most accounts agree ^[2]. His uncommon rise from such origins to the papal throne became part of his legend even during his lifetime.

As a boy he was sent to Rome, where an uncle served as superior of the monastery of Santa Maria on the Aventine hill. There Hildebrand received his education and absorbed the monastic discipline that shaped his outlook for the rest of his life ^[1]. Contemporary sources describe him as small in stature and unimpressive in appearance, yet possessed of a forceful will that struck nearly everyone who dealt with him ^[2].

Rome in the 1030s and 1040s gave the young monk a close view of the papacy at a low point. Roman aristocratic families traded the office among their candidates, and in 1046 three rival claimants held the title at once. The German king Henry III intervened, deposed all three at the synods of Sutri and Rome, and installed a series of reform-minded German popes ^[3]. Hildebrand attached himself to one of the deposed pontiffs, Gregory VI, and followed him into exile in Germany, an experience that put him in contact with the reform circles north of the Alps ^[1].

After Gregory VI died in exile, Hildebrand returned to Rome in 1049 in the entourage of the new pope, Leo IX, a Lotharingian reformer who gathered talented clerics around him. Leo made Hildebrand a subdeacon and put him in charge of the finances of the Roman church, and he restored the fortunes of the monastery of Saint Paul Outside the Walls as its rector ^[1]. Over the following two decades he served six successive popes as administrator, legate, and negotiator, becoming the most experienced figure in the papal government ^[2].

His diplomatic missions carried real weight. He traveled to France to deal with the eucharistic teaching of Berengar of Tours, and he played a part in the disputed papal elections that followed the deaths of Leo IX and his successors ^[2]. In 1059 he helped shape one of the era's decisive measures: the election decree of Nicholas II, which placed the choice of a new pope primarily in the hands of the cardinal bishops and pushed the Roman aristocracy and the German court toward the margins of the process ^[3]. The same year brought an alliance with the Norman rulers of southern Italy, giving the reform papacy an armed protector for the first time.

By the pontificate of Alexander II (1061 to 1073), Hildebrand held the office of archdeacon of the Roman church and was widely regarded as the power behind the throne ^[1]. Peter Damian, a fellow reformer with a sharp pen, called him a "holy Satan", a phrase that captured both the admiration and the unease Hildebrand provoked ^[2]. When Alexander II died in April 1073, the crowd at the funeral acclaimed Hildebrand as pope, and the cardinals confirmed the choice. He took the name Gregory VII, honoring both Gregory the Great and his old master Gregory VI ^[1].

Gregory inherited a reform movement and radicalized it. The program targeted two entrenched abuses: simony, the buying and selling of church offices, and clerical marriage, which reformers saw as entangling the clergy in worldly dynasties ^[3]. At Roman synods in 1074 and 1075 Gregory renewed the prohibitions with unusual severity, ordering the laity to boycott services held by married or simoniac priests, a step that caused uproar among clergy in Germany, France, and Italy ^[4].

The most explosive measure came in 1075, when Gregory banned lay investiture, the custom by which kings and nobles conferred the ring and staff of office on bishops and abbots ^[3]. Since bishops in the German kingdom were also great landholders and royal administrators, the decree struck directly at the machinery of monarchy. To Gregory the issue was one of principle: church offices were spiritual trusts, not royal property, and their holders answered to Rome ^[4].

A remarkable document from March 1075, the Dictatus Papae, survives in Gregory's official register. Its twenty-seven terse propositions claim, among other things, that the Roman pontiff alone may depose bishops, that he may depose emperors, that he can be judged by no one, and that the Roman church has never erred ^[5]. Scholars still debate its exact purpose, whether a private memorandum, an index for a planned canon law collection, or a manifesto, but it distills the papal monarchy Gregory envisioned with startling clarity ^[4]. Any list of Pope Gregory VII achievements begins with this transformation of the papacy from a Roman bishopric into a claimed supreme authority over Latin Christendom.

The investiture ban collided with the German king Henry IV, who had just crushed a Saxon rebellion and had no intention of surrendering control over his bishops. When Henry continued to invest bishops in Italy, including a candidate for the great see of Milan, Gregory sent him a sharp warning in December 1075 ^[3]. Henry answered in January 1076 by assembling his bishops at Worms, where they renounced obedience to Gregory in a letter addressed contemptuously to "Hildebrand, not pope but false monk" ^[4].

Gregory's reply was without precedent. At his Lenten synod of February 1076 he excommunicated Henry, suspended him from ruling, and released his subjects from their oaths of fealty ^[1]. No pope had ever claimed to depose a reigning king in this manner. The sentence proved devastatingly effective because Henry's German enemies seized on it: the princes declared that unless the king obtained absolution within a year, they would elect a replacement, and they invited Gregory to judge the case in Germany ^[3].

Henry chose submission over deposition. In January 1077 he crossed the Alps in winter and appeared before the fortress of Canossa in the Apennines, where Gregory was staying as the guest of Countess Matilda of Tuscany. According to Gregory's own account in a letter to the German princes, the king waited before the gate for three days as a barefoot penitent in woolen clothing before the pope absolved him ^[5]. Canossa restored Henry to communion, but it settled nothing. The German opposition elected an anti-king, Rudolf of Swabia, and civil war followed. Gregory excommunicated and deposed Henry a second time in 1080, but Rudolf died of wounds that same year, and the sentence no longer commanded the assent it had in 1076 ^[4].

Henry struck back on Gregory's own ground. At Brixen in June 1080 a council of imperial bishops declared Gregory deposed and named Guibert, archbishop of Ravenna, as a rival pope under the name Clement III ^[3]. Henry then marched on Rome. After repeated sieges the city fell to him in March 1084, Guibert was enthroned in Saint Peter's, and the antipope crowned Henry emperor ^[1]. Gregory held out in the fortress of Castel Sant'Angelo, refusing every compromise.

Rescue came at a terrible price. Robert Guiscard, the Norman duke of Apulia and Gregory's sworn vassal, arrived with a large army and drove Henry off, but his troops then sacked Rome with such violence that the population turned its fury on the pope who had summoned them ^[3]. Gregory could not safely remain in the city. He withdrew with the Normans, first to Monte Cassino and then to Salerno on the Tyrrhenian coast.

He spent his final months in Salerno, still issuing letters and maintaining every claim he had ever advanced. He died there on May 25, 1085 ^[1]. A tradition recorded soon after his death gives him the parting words that he had loved justice and hated iniquity, and therefore died in exile, an adaptation of a psalm verse that his followers treated as a summary of his life ^[2]. He was buried in the cathedral of Salerno, where his tomb remains.

Gregory left an unusually rich personal record for a medieval pope. His official register, preserved in the Vatican Archives, contains roughly 360 letters in his name, and dozens more survive outside it ^[5]. The correspondence shows a ruler who wrote with urgency and biblical saturation, quoting scripture constantly and returning again and again to the word "justice". Among the verses he cited most was Jeremiah's curse on the one who keeps his sword from blood, which he read as a warning against slackness in God's cause ^[4].

He never abandoned the habits of a monk. Sources connected him with the Roman monastic milieu of his youth, and although a long-standing claim that he professed vows at Cluny is doubted by many modern historians, his asceticism was not in question even among enemies ^[2]. He relied heavily on a small circle of trusted allies, above all Matilda of Tuscany, whose lands and soldiers shielded the reform papacy, and Hugh, abbot of Cluny, his frequent correspondent ^[4].

Contemporaries disagreed violently about him, and the disagreement has never fully ended. To supporters he was a fearless liberator of the church from lay control. To critics, including some fellow reformers, he was rash, inflexible, and too ready to sanctify war. Modern biographers such as H. E. J. Cowdrey have portrayed a man of genuine religious conviction whose certainty about God's will made compromise nearly impossible ^[4].

The struggle Gregory began outlived him by decades. The Investiture Controversy continued under his successors until the Concordat of Worms in 1122 produced a compromise: the emperor gave up investing bishops with ring and staff, while retaining a role in their election within Germany ^[3]. The distinction that settlement drew between the spiritual office and its worldly possessions marked a lasting change in how Europeans thought about the boundary between religious and political power ^[6].

Historians came to name the whole eleventh-century transformation after him. The Gregorian Reform made the papacy the effective head of the Latin church, centralized appeals and legislation in Rome, and fixed clerical celibacy as the Western norm ^[3]. Some scholars have gone further, arguing that the Gregorian insistence on the church's freedom from lay control helped generate the Western legal tradition itself by forcing a systematic definition of competing jurisdictions ^[6].

The church honored him slowly. Gregory was beatified in 1584 and canonized by Paul V in 1606, and his feast is kept on May 25 ^[1]. The extension of his feast to the whole church in the eighteenth century provoked protests from Catholic monarchies that still bristled at his deposition of a king, evidence of how long his memory retained its edge ^[2]. Among the essential Pope Gregory VII facts is this durability: nearly a millennium after Canossa, his name remains shorthand for the claim that spiritual authority answers to no earthly power. Any Pope Gregory VII biography is finally the story of that claim and its price.
