Pope Blessed Urban II (c.1035-1099)

The pope who launched the First Crusade

No speech of the Middle Ages had consequences as far-reaching as that of Urban II at Clermont. In a few months, tens of thousands of men, from princes to the poor, took up the cross to march toward Jerusalem. The First Crusade (1095–1099) opened two centuries of expeditions, founded the Latin States of the East, and permanently transformed relations between Christendom, Byzantium, and Islam.^[8][9]

However, recent historiography has corrected the image of a pope launching a war of conquest on a whim. Urban II acted as a diplomat: he responded to a documented request from Constantinople, imposed a strict penitential discipline on the expedition, and entrusted its spiritual direction to a legate. The crusade was born at the intersection of Church reform, the defense of Eastern Christians, and a spirituality of pilgrimage.^[10][11][12]

A great architect of the Gregorian reform

Urban II is often reduced to Clermont. This overlooks the essential part of his work: he saved the Gregorian reform at a time when it seemed lost. At his election, Rome belonged to the antipope, Emperor Henry IV dominated northern Italy, and the reform party was divided. In eleven years, Urban reconquered the City, reunited the Sacred College (the assembly of cardinals), held a series of councils that reaffirmed the program of the Church’s freedom, and gave the papacy a moral authority that radiated throughout the West.^[13][14]

Birth in Champagne and Studies at Reims

Odo — the Latin form Odo is the most common — was born around 1035 into a family of the lesser nobility of Champagne, at Lagery, near Châtillon-sur-Marne.^[15] He studied at the cathedral school of Reims, one of the great intellectual centers of the Kingdom of France, where his teacher is said to have been Saint Bruno, the future founder of the Carthusian Order. Having become a canon and then archdeacon of Reims, the young cleric steadily rose through the diocesan administration.^[16][17]

Entering Cluny under Saint Hugh

Around 1070, at the height of a promising career, Odo broke with the world and entered the Abbey of Cluny, then the most prestigious monastery in the West, under the leadership of the great abbot Saint Hugh. The Cluniac reform—exemption from lay control, sumptuous liturgical life, spiritual influence over hundreds of priories—would permanently shape his vision of the Church. He was soon appointed prior, second in the monastery after the abbot.^[18][19]

This Cluniac formation is decisive for understanding the man. The reform of which Urban II would become one of the leaders was not, at its core, a policy: it was a monastic ideal of purity and freedom for the Church, projected onto universal governance. Cluniac historiography, in line with the work of Alfons Becker, sees in it Cluny’s distinctive contribution to the reform of the Church: not primarily a doctrine, but the experience of a community removed from lay power and wholly ordered to God.^[20]

Cardinal-Bishop of Ostia and Legate in Germany

Around 1080, Gregory VII summoned the prior of Cluny to Rome and made him Cardinal-Bishop of Ostia, one of the highest dignitaries of the Curia. Odo became one of the most trusted collaborators of the reforming pope. In 1084-1085, Gregory sent him as legate (his personal representative) to Germany, at the heart of the conflict between the papacy and Emperor Henry IV. There, the legate held synods—including the great synod of Quedlinburg, where the antipope Guibert of Ravenna was anathematized by name—and supported the bishops loyal to Rome. He had already experienced, while returning to Rome in 1083, a brief captivity at the hands of Henry IV, from which he was soon freed.^[21][22]

At the death of Gregory VII (1085), and after the brief pontificate of Blessed Victor III (1086-1087), the Cardinal of Ostia appeared as the natural heir to the Gregorian program.

The Legacy of Gregory VII and the Schism

Urban II inherited an almost desperate situation. Gregory VII had died in exile at Salerno, driven from Rome by Henry IV. The emperor had an antipope elected, Guibert of Ravenna, who reigned under the name Clement III and occupied much of Rome, sometimes even Saint Peter's itself. The schism divided the European episcopate; many dioceses hesitated between the two obediences.^[23][24]

Terracina, March 12, 1088

It was under these conditions that Odo of Lagery was elected, on March 12, 1088, not in Rome but at Terracina, south of Latium, by a small assembly of cardinals and loyal prelates. He took the name Urban II and immediately presented himself as the continuator of Gregory VII, declaring his intention to follow in all things the footsteps of his master.^[25]

Reconquering Rome from Antipope Clement III

During the first years of his pontificate, Urban II was hardly master of Rome. He wandered through Norman southern Italy, supported by the dukes Roger Borsa and Roger of Sicily, held councils in exile, and only returned permanently to the city from 1093-1094, when the weakening of the imperial camp allowed him to retake the Lateran—at the price, it is said, of a sum paid to the guardian of the fortress.^[26][27]

This tenacity in adversity is one of the keys to his character. Without an army of his own, without a secure capital, Urban II patiently rebuilt papal authority through synods, diplomacy, and the loyalty of a network of reforming bishops and monks.

Simony, Nicolaitism, and Lay Investiture

At the heart of the Gregorian reform, which Urban II brings to maturity, lie three inseparable battles. Against simony—the trafficking of offices and sacraments—which corrupted access to ecclesiastical positions. Against nicolaitism—the concubinage and marriage of clerics—which threatened the discipline and patrimony of the Church. Against lay investiture—the conferral of the episcopal crozier and ring by a prince—which made bishops vassals of temporal powers.^[28][29]

These three fronts are not mere administrative disputes: they concern the freedom of the Church (libertas Ecclesiae), that is, her ability to choose her pastors according to God and not according to the interests of the powerful. It is this same demand for freedom that will open, after Urban II, the long Investiture Controversy, which will only be resolved in 1122 by the Concordat of Worms.^[30]

The Reform Councils: Melfi, Piacenza, Clermont

Urban II governs through councils. As early as September 1089, the Council of Melfi, in Norman territory, reaffirms the prohibition of simony, clerical marriage, and lay investiture. This is followed by Piacenza and Clermont in 1095, a tour of synods in France in 1096, Bari in 1098, and a final Lateran synod in 1099. The table below summarizes this intense conciliar activity.^[31][32]

Anti-Imperial Diplomacy: Matilda, Conrad, Praxede

To loosen the grip of Henry IV, Urban II deploys skillful diplomacy in Northern Italy. In 1089, he encourages the marriage of the powerful Countess Matilda of Tuscany, pillar of the papal party, with the young Welf of Bavaria, sealing an alliance against the emperor. He welcomes the defection of Conrad, son of Henry IV, who rebels against his father, rallies to the pope, and receives his support. Finally, at the Council of Piacenza, Empress Praxede (Eupraxia of Kiev), the repudiated wife of Henry IV, comes to publicly accuse her husband of degrading treatment—a scandal that further undermines imperial prestige.^[33][34]

When the year 1095 opens, Urban II is no longer the wandering pope of his early days: he has once again become the moral arbiter of Western Christendom. It is from this restored position that he will launch the call of Clermont.

The Council of Piacenza and the Embassy of Alexios Komnenos

At the Council of Piacenza in March 1095, ambassadors of the Byzantine Emperor Alexios I Komnenos appeared. Since the defeat at Manzikert (1071), the Eastern Empire had lost much of Asia Minor to the Seljuk Turks; Alexios requested military reinforcements from the West to repel Muslim pressure. The principal narrative source for this embassy, the chronicler Bernold of Constance, reports that the pope exhorted many faithful to swear an oath to aid the emperor.^[35][36] The Byzantine context of this request for help is also known, from the Greek side, through the later, partial but rich testimony of Alexios I's own daughter, Princess Anna Komnene, in her Alexiad.^[37]

"The lord pope exhorted many [...] to faithfully promise by oath that they would go to aid the emperor." — Bernold of Constance, Chronicon, for the year 1095^[38]

Thus, Piacenza is not yet the call to crusade; but it is here that the idea of a Western expedition to the Christian East takes root. Between March and November, Urban II developed a much broader project: not merely reinforcements for Byzantium, but an armed pilgrimage whose ultimate goal would be Jerusalem itself.^[39][40]

The Council of Clermont, 18–28 November 1095

The Council of Clermont, in Auvergne, gathered from 18 to 28 November 1095 more than two hundred bishops and abbots. It first addressed issues of ecclesiastical discipline: renewal of the Truce of God (which forbade private wars on certain days and protected clergy, pilgrims, and peasants), condemnation of simony, clerical marriage, and lay investiture, and the excommunication of the King of France, Philip I, for his adulterous union.^[41][42]

It was only at the conclusion of these proceedings, on 27 November 1095, that the pope delivered, in the open air before a crowd too large for the cathedral, the speech calling for the liberation of Jerusalem and the Christians of the East. The event was so momentous that at least four chroniclers left versions of it—but none is a transcript: each reconstructs the speech according to his own perspective and the success of the crusade.^[43][44]

The Speech of 27 November: "God wills it!"

The versions differ, but agree on the essentials: Urban II describes the sufferings of the Christians of the East, exhorts knights to cease their private wars to fight the enemies of the faith, and promises a spiritual reward to those who depart out of devotion. The most restrained version, that of the eyewitness Fulcher of Chartres, redirects feudal violence toward a just cause.^[45]

"Let those who were formerly accustomed to wage wicked private wars against the faithful now fight against the infidels. [...] Let those who were robbers become soldiers." — Fulcher of Chartres, Historia Hierosolymitana, I, 3 (c. 1101)^[46]

According to Robert the Monk, who claims to have been present, the crowd interrupted the pope with a unanimous acclamation that became the battle cry of the crusaders:

"God wills it! God wills it!" — Acclamation reported by Robert the Monk, Historia Iherosolimitana (c. 1107)^[47]

The table below compares the four major accounts of the speech, to remind the reader that we do not possess the exact text, but four concordant reconstructions.

The Crusade Indulgence: A Penitential Act, Not a License to Kill

The doctrinally decisive point of Clermont is not the cry of the crowd, but the indulgence promised by the pope. Canon 2 of the council, as transmitted by the report of Lambert, Bishop of Arras, edited by historian Robert Somerville, gives the formula:^[50]

"Whoever, moved solely by devotion and not to gain honor or money, sets out for Jerusalem to liberate the Church of God, this journey shall be counted to him as full penance." — Canon 2 of the Council of Clermont, 1095^[51]

This text must be read carefully, for it has often been caricatured. The indulgence is not a license to kill, nor a reward for pillage: the formula requires "solely by devotion and not to gain honor or money." It fits within the penitential logic of the time: the crusader undertakes a pilgrimage of extreme difficulty, which serves as the canonical penance owed for sins already confessed. It is a remission of penalty, presupposing contrition and confession, not a magical absolution for future crimes.^[52][53] Historian Christopher Tyerman makes this penitential logic the key to understanding the Crusades.^[54]

For a comprehensive discussion of legitimacy, violence, and modern objections, the reader is referred to the dossiers The Crusades and The First Crusade, which address in detail the question of just war, the massacres of 1096 and 1099, and the real extent of papal responsibility.

The Letter to the Flemings and the Organization of the Expedition

Urban II did not launch an uncontrolled movement: he organized it. As early as December 1095, he sent a letter to the faithful of Flanders—one of the rare documents emanating directly from the pope about the crusade—in which he sets out the cause and names a leader.^[55]

“Your fraternity has, we believe, long since learned that a barbaric fury has deplorably ravaged the churches of God in the regions of the East. [...] We have appointed our most beloved son Adhemar, bishop of Le Puy, as leader of this expedition in our place.” — Urban II, Letter to the Faithful of Flanders, December 1095^[56]

The pope set the departure for August 15, 1096, the feast of the Assumption, and entrusted the spiritual leadership of the expedition to his legate Adhemar of Le Puy, the first to receive the cross at Clermont. The great lord Raymond of Saint-Gilles, Count of Toulouse, was among the first to commit. In this way, Urban oversaw an enterprise of which he would remain, until his death, the distant master builder.^[57][58]

He was careful, however, to distinguish the crusade from the excesses that accompanied it: the poorly supervised bands of the “popular crusade” led by Peter the Hermit, who set out prematurely, and especially the massacres of Jewish communities in the Rhineland in the spring of 1096, which the Church neither desired nor authorized.^[59][60]

In October 1098, Urban II presided at Bari, in Apulia, over a great council bringing together—according to tradition—about 185 bishops, many of whom were Greek-rite bishops from southern Italy, recently brought under Norman rule. The aim was reconciliation between Latins and Greeks, separated since the schism of 1054, on the controversial question of the Filioque: the procession of the Holy Spirit “from the Father and the Son.”^[61]

One of the greatest theologians of the time, Anselm of Canterbury, then exiled from England, played a key role. At the pope’s request, he delivered a masterful discourse on the procession of the Holy Spirit, defending the Latin doctrine before the assembly. His biographer Eadmer reports that Urban II personally called upon him to speak as an authority. From this intervention would arise the treatise De Processione Spiritus Sancti.^[62][63]

“Father and master Anselm, Archbishop of the English, where are you?” — Words of Urban II calling Anselm to speak at the Council of Bari, according to Eadmer of Canterbury, Historia Novorum, II^[64]

The Council of Bari did not end the Eastern Schism—none of the major Greek Churches were represented—but it demonstrates Urban II’s concern for the unity of the Church and the theological seriousness of his pontificate, too often reduced to the Crusade alone.^[65][66]

Urban II’s final years were devoted to consolidating the reconquered Rome, continuing the reform, and following from afar the progress of the crusaders. In April 1099, he held a final Lateran synod, renewing the reforming decrees.^[67]

In the summer of 1099, the Crusade reached its goal. Jerusalem fell on July 15, 1099. But Urban II died in Rome on July 29, 1099, fourteen days later, before news of the capture of the Holy City could reach him. He was buried in the crypt of the old St. Peter’s Basilica, near the tomb of Hadrian I; this tomb no longer exists today.^[68][69][70] His successor, Paschal II, would inherit the dual task of continuing the reform and supporting the young Latin states of the East.

Blessed Urban II

The cult of Urban II, vibrant since the Middle Ages in Cluniac and Roman circles, was officially confirmed by Leo XIII on July 14, 1881, which is equivalent to a beatification. His memory is celebrated on July 29, the anniversary of his death (dies natalis), without inscription in the General Roman Calendar.^[71][72] The liturgical memory honors him as a reformer and a servant of unity, more than merely as the preacher of the crusade.

A Contested Figure: Responding Honestly

Urban II is perhaps the medieval pope whose image suffers most from modern controversies over the crusades. For many, he embodies “holy war” and religious intolerance. This reading calls for three clarifications, in line with the current state of research.

First, the call of Clermont is a response, not a spontaneous act of aggression: it follows the request for aid from Alexios Komnenos and decades of Turkish advances in Asia Minor and the Levant.^[73][74] Next, the crusade as envisioned by Urban is a penitential pilgrimage, governed by spiritual discipline, not a license for massacre: the real acts of violence—such as the Rhineland pogroms of 1096 and the sack of Jerusalem in 1099—were neither ordered nor authorized by him, and several occurred after his death or at the time of his passing.^[75][76] Finally, his work is not limited to Clermont: the freedom of the Church and the pursuit of unity with the Greeks are as significant in his pontificate as the Eastern expedition.^[77][78]

Recognizing the shadows in the history of the crusades does not require attributing to Urban II faults that were not his. The blessed whom the Church honors is a reforming monk who, in an age of iron, sought to free the Church from the power of princes and to aid threatened Christians—with the means and limitations of his time.
