Cerularius refused resulting in the leader of the contingent from Rome excommunicating Cerularius and the legates in turn being excommunicated by Constantinople. Though this event, in and of itself, was relatively insignificant (and the authority of the legates in their actions was dubious) it ultimately marked the end of any pretense of a union

). The end of lay investiture threatened to undercut the power of the Empire and the ambitions of noblemen for the benefit of Church reform.

Bishops collected revenues from estates attached to their bishopric. Noblemen who held lands (fiefdoms) hereditarily passed those lands on within their family. However, because bishops had no legitimate children, when a bishop died it was the king's right to appoint a successor. So, while a king had little recourse in preventing noblemen from acquiring powerful domains via inheritance and dynastic marriages, a king could keep careful control of lands under the domain of his bishops. Kings would bestow bishoprics to members of noble families whose friendship he wished to secure. Furthermore, if a king left a bishopric vacant, then he collected the estates' revenues until a bishop was appointed, when in theory he was to repay the earnings. The infrequence of this repayment was an obvious source of dispute. The Church wanted to end this lay investiture because of the potential corruption, not only from vacant sees but also from other practices such as simony

Ecclesiology

At the root of what became the Great Schism is the question of ecclesiology. The Eastern Churches maintained the idea that every local city-Church with its bishop, presbyters, deacons and people celebrating the Eucharist constituted the whole Church. In this view called Eucharistic ecclesiology (or more recently holographic ecclesiology), every bishop is Peter's successor in his Church ("the Church") and the Churches form what Eusebius called a common union of Churches. This implied that all bishops were ontologically equal, although functionally particular bishops could be granted special privileges by other bishops and serve as metropolitans, archbishops or patriarchs. Early on, the ecclesiology of the Roman Church was universal in nature, with the idea that the Church was a worldwide organism with a divinely (not functionally) appointed center: the Church/Bishop of Rome. These two views are still present in modern Roman Catholicism and Eastern Orthodoxy and can be seen as foundational causes for the schisms and Great Schism between East and West.

Language and culture

Many other factors caused the East and West to drift further apart. The dominant language of the West was Latin

 (1054) on the altar.

The consummation of the schism is generally dated from the year 1054, when this sequence of events took place. However, these events only triggered the beginning of the schism but the schism was not actually consummated by the seemingly mutual excommunications. The New Catholic Encyclopedia reports that the legates had been careful not to intimate that the Bull of Excommunication implied a general excommunication of the Byzantine Church. The bull excommunicated only Caerularius, Leo of Achrida, and their adherents. Thus, the New Catholic Encyclopedia argues that the dispute need not have produced a permanent schism any more than excommunication of any "contumacious bishop". The schism began to develop when all the other Eastern patriarchs supported Caerularius. According to the New Catholic Encyclopedia, it was the support of Emperor Michael VI Stratiotikos that impelled them to support Caerularius. Some have questioned the validity of the bull on the grounds that Pope Leo IX had died at that time and so the authority of the legates to issue such a bull is unclear.

The legates left for Rome two days after issuing the Bull of Excommunication, leaving behind a city near riot. The patriarch had the immense support of the people against the Emperor, who had supported the legates to his own detriment. To assuage popular anger, the bull was burnt, and the legates were anathema

tised. It should be noted here that only the legates were anathematised and, once again, there was no explicit indication that the entire Western church was being anathematised.

In the bull of excommunication issued against Patriarch Michael by the papal legates, one of the reasons cited was the Eastern Church's deletion of the "Filioque" from the original Nicene Creed. In fact, it was precisely the opposite: the Eastern Church did not delete anything. It was the Western Church that added this phrase to the Nicene-Constantinopolitan Creed.

"Even after 1054 friendly relations between East and West continued. The two parts of Christendom were not yet conscious of a great gulf of separation between them. … The dispute remained something of which ordinary Christians in East and West were largely unaware". In fact, efforts were made in subsequent centuries by Popes and Patriarchs to heal the rift between the churches. However, a number of factors and historical events worked to widen the separation over time.

Christianity and knighthood in the Middle Ages

The nobility of the Middle Ages was a military class; in the Early Medieval period a king (rex) attracted a band of loyal warriors (comes) and provided for them from his conquests. As the Middle Ages progressed, this system developed into a complex set of feudal ties and obligations. As Christianity had been accepted by barbarian nobility, the Church sought to prevent ecclesiastical land and clergymen, both of which came from the nobility, from embroilment in martial conflicts. By the early eleventh century, clergymen and peasants were granted immunity from violence – the Peace of God (Pax Dei). Soon the warrior elite itself became "sanctified", for example fighting was banned on holy days – the Truce of God (Treuga Dei). The concept of chivalry developed, emphasising honour and loyalty amongst knights, and, with the advent of Crusades, holy orders of knights were established who perceived themselves as called by God to defend Christendom against Muslim advances in Spain, Italy, and the Holy Land, and pagan strongholds in Eastern Europe.

This activity brought considerable wealth and power. Wealthy lords and nobles would give the monasteries estates in exchange for the conduction of masses for the soul of a deceased loved one. Though this was likely not the original intent of Benedict, the efficiency of his cenobitic Rule in addition to the stability of the monasteries made such estates very productive; the general monk was then raised to a level of nobility, for the serf

s of the estate would tend to the labor, while the monk was free to study. The monasteries thus attracted many of the best people in society, and during this period the monasteries were the central storehouses and producers of knowledge.

The system broke down in the eleventh and twelfth centuries as religion began to change.

A traditional numbering scheme for the crusades totals nine during the 11th to 13th centuries. This division is arbitrary and excludes many important expeditions, among them those of the 14th, 15th, and 16th centuries. In reality, the crusades continued until the end of the 17th century, the crusade of Lepanto

. In 1039 his successor, after requiring large sums be paid for the right, permitted the Byzantine Empire to rebuild it. Pilgrimages were allowed to the Holy Lands before and after the Sepulchre was rebuilt, but for a time pilgrims were captured and some of the clergy were killed. The Muslim conquerors eventually realized that the wealth of Jerusalem came from the pilgrims; with this realization the persecution of pilgrims stopped. However, the damage was already done, and the violence of the Seljuk Turks became part of the concern that spread the passion for the Crusades.

. It was a hotly debated issue throughout the Crusades as what exactly "remission of sin" meant. Most believed that by retaking Jerusalem they would go straight to heaven after death. However, much controversy surrounds exactly what was promised by the popes of the time. One theory was that one had to die fighting for Jerusalem for the remission to apply, which would hew more closely to what Pope Urban II

Another theory was that if one reached Jerusalem, one would be relieved of the sins one had committed before the Crusade. Therefore one could still be sentenced to Hell

After the First Crusade

On a popular level, the first crusades unleashed a wave of impassioned, personally felt pious Christian fury that was expressed in the massacres of Jews that accompanied the movement of the Crusader mobs through Europe, as well as the violent treatment of "schismatic" Orthodox Christians of the east. During many of the attacks on Jews, local Bishops and Christians made attempts to protect Jews from the mobs that were passing through. Jews were often offered sanctuary in churches and other Christian buildings.

The ruler of Antioch was not sure how the Christians living within his city would react and he forced them to live outside the city during the siege, though he promised to protect their wives and children from harm, while Jews and Muslims fought together. The siege only came to end when the city was betrayed and the Franks entered through the water-gate of the town causing the leader to flee. Once inside the city, as was standard military practice at the time, the Franks then massacred the civilians, destroyed mosques and pillaged the city. The crusaders finally marched to the walls of Jerusalem with only a fraction of their original forces.

Siege of Jerusalem


The Jews and Muslims fought together to defend Jerusalem against the invading Franks. They were unsuccessful though and on 15 July 1099 the crusaders entered the city. Again, they proceeded to massacre the remaining Jewish and Muslim civilians and pillaged or destroyed mosques and the city itself. One historian has written that the "isolation, alienation and fear" felt by the Franks so far from home helps to explain the atrocities they committed, including the cannibalism which was recorded after the Siege of Maarat in 1098. As a result of the First Crusade, several small Crusader states

When the Franks were defeated the people of Tyre did not surrender the city, but Zahir al-Din simply said "What I have done I have done only for the sake of God and the Muslims, nor out of desire for wealth and kingdom."

Eventually, the Muslims began to reunite under the leadership of Imad al-Din Zangi. He began by re-taking Edessa in 1144. It was the first city to fall to the Crusaders, and became the first to be recaptured by the Muslims. This led the Pope to call for a second Crusade.
