The crusading movement encompasses the framework of
personal relationships with Christ. The institution of crusading developed with the encouragement of church reformers the 11thcentury in what is commonly known as the Gregorian Reform and declined after the 16thcentury Protestant Reformation
.
The idea of crusading as holy war was based on the Greco-RomanJust war theory. A "just war" was one where a legitimate authority is the instigator, there is a valid cause, and it is waged with good intentions. The Crusades were seen by their adherents as a special Christian pilgrimage – a physical and spiritual journey authorised and protected by the Church. The actions were both a pilgrimage and penitental, Participants were considered part of Christ's army and demonstrated this by attaching crosses of cloth to their outfits. This marked them as followers and devotees of Christ and was in response to biblical passages exhorting Christian "to carry one's cross and follow Christ". Everyone could be involved, with the church considering anyone who died campaigning a Christian martyr. This movement was an important part of late-medieval western culture, that impacted politics, the economy and wider society.
The original focus and objective was the liberation of
heretics in France, Germany, and Hungary, as well as in Italy where Pope's indulged in armed conflict with their opponents. By definition all the crusades were waged with papal approval and through this reinforced the Western European concept of a single, unified Christian Church under the Pope
The Crusading movement's origins can be found in the significant changes within the Latin church during the mid-eleventh century. In the 1040s church
holy war and would eventually seek to enact it.[7][8]
Three initiatives were necessary before this could be but into action. Firstly, this reform of the Latin Church into an independent force that was motivated by the belief it had divine authority for religious renewal. This belief would lead to conflicts with the Holy Roman Empire, Muslim states, other Christian groups, and pagans. Secondly, the creation of crusading as a social institution through which the church could act militarily supported by armed nobility considered Knights of Christ.[9][10][11] Lastly, the development of formal army structures for the raising of armies through which the church could advance its ambitions.[9][10] The developments would lead to violent conflicts between the Church and its adversaries and have an impact on broader social and political transformations. These factors enabled the crusading movement, and its decline corresponded with their decreasing significance.[12]
Erdmann documented in The Origin of the Idea of Crusade the three stages of the development of a Christian institution of crusade:
the argument that preserving Christian unity was a just cause for warfare;
the ideas developed under Pope Gregory I that the conquest of pagans in an indirect missionary war was also in accordance;
The paradigm developed under the reformist popes Leo IX, Alexander II, and Gregory VII, in the face of Islamic conflict, that war should be waged to defend Christendom.[13]
Historians, such as Erdmann, believed that from the 10thcentury the
Norman conquest of the Emirate of Sicily.[15] For the philosophers and combatants, the conflict in Spain provided practical foundational arguments for the movement.[16] In 1074, Gregory VII planned a holy war in support of Byzantium's struggles with Muslims, which produced a template for a crusade, but he was unable to garner the required support, possibly because he stated he intended to lead the campaign himself.[17]
The Church defined crusading in legal and theological terms based on the theory of holy war and the concept of
Christocentric concept of forming an individual relationship with Christ that came from the New Testament. Holy war was based on bellum justum which was the Greco-Romanjust war theory. This was Christianised by a 4th-century theologian called Augustine of Hippo, and canon lawyers developed this further in the 11thcentury into bellum sacrum. This is what became the paradigm of Christian holy war.}[18] Augustine's argument was that war was sinful, but a "just war" could be rationalised if three criteria were met. These criteria were that the war must be declared by a legitimate authority, it was defensive or for the recovery of rights or property and the combatants intentions must be good.[19][20] Later, Anselm of Lucca consolidated the writing on just war theories into Collectio Canonum or Collection of Canon Law.[21] In the 13thcentury these principles formed the foundation of a doctrine of religious war developed by Thomas Aquinas and others.[22] The church used canon law to justify various Italian wars. This was by judging Rome as the Patrimony of Saint Peter and any papal war as being waged by the church in purely defensive crusades to protect theoretical Christian territory.[23]
penance for those who journeyed to Jerusalem to recover the holt places and the protection of all goods and property while doing so.[25] Subsequently, later Popes developed this into the granting of plenary indulgence that removed the guilt and the sins as well as just the God-imposed punishment.[26]
The weakness of conventional theology when confronted by crusading excitement was evident in a letter critical of
As late as the 16thcentury, writers were still looking for redemption in crusading, while others – such as English
Roman Catholics could agree on other grounds for the Turkish wars and the role of the granting of indulgence declined.[34]Alberico Gentili and Hugo Grotius developed international laws of war that discounted religion as a cause, in contrast to popes, who persisted in issuing crusade bulls for generations.[35]
Knights and chivalry
Further information:
Knighthood
When crusading began chivalry was just developing, but in time it played a central role in the crusading ethos, by shaping the ideals and principles of knights. The knighthood was separate from the aristocracy while being praised in literature.[36] The control of fortifications dominated society. The men who manned these became the basis of the knighthood. Simultaneosly, new military tactics based on the use of heavy cavalry combined with the growing naval capability of Italy's maritime republics, made the First Crusade feasible. The new methods of warfare led to codes, ethics, and ideologies. Knighthood required combat training, leading to solidarity and the rise of combat as sport.[37] The resulting tournaments were used by crusade preachers to obtain vows of support from attendees, conduct campaigns of persuasion, and make announcements of senior figures taking of the cross.[38] Despite the courage of knights and some notable generalship, the crusades in the Levant were typically unimpressive. Military strategy and medieval institutions were immature in feudal Europe at the time and power was too fragmented for the creation of disciplined units.[39]
The idealised perfect knight was represented in literature such as the c1130 romance Alexandre. This related adventurous ideas of the courage, charity, and good manners. These ideals of excellence, martial glory, and romantic love conflicted with the spiritual views of the Church. While the Church feared this knightly caste, it also co-opted it for support. The Church developed liturgical blessings to sanctify new knights..[40] Kings even began depicting themselves as knights to order to project their power.[41]
Crusade participation was considered integral to idealised knightly behaviour.[42] It became part of the knightly class's self-identification, in a way that created a cultural gap with other social classes.[43] From the Fourth Crusade onward, crusading became an adventure that was normalised in Europe. This altered the relationship between knightly enterprise, religious, and worldly motivation.[44]
There were few innovations in the crusading movement that originated from the polities created in the Eastern Mediterranean following the First Crusade. These polities are generally known as the Crusader states and they tended to follow the customs of western European homelands. One of the exceptions was the creation of military religious orders.[45]
The Knights Hospitaller were delivering ongoing medical functions in Jerusalem before the First Crusade but added a martial element to their to become a much larger military order. The Knights Templar were founded around 1119 by a small band of knights who dedicated themselves to protecting pilgrims en route to Jerusalem. Many other orders followed.[46] These military orders were Latin Christendom's first professional armies, supporting the Kingdom of Jerusalem and the other crusader states. [47] In time they developed a reach that crossed national borders. This was through papal support that led rich donations of land and revenue across Europe, a steady flow of recruits and the wealth to maintain multiple fortifications. Eventually, the orders even developed independent autonomous powers.[48]
When the Latin Christian control of territory in the Holy Land ended after the
In the movement's early years papal recruitment concentrated on warriors, but it was impossible to exclude non-knightly participants. Grooms, servants, smiths, armourers, and cooks provided services and fought if required. Traveling armies also included women.
Holy Sepulchre and dedicated chapels. Although, these acts predated crusading, they grew in popularity and may have provided a backdrop to Easter Drama or sacramental liturgy. In this way, what was known as the remotest place in 1099 became embedded in daily devotion, providing a visible sign of what crusading was about.[55]
In 1096, 1212, 1251, 1309, and 1320 uncontrolled peasant crusading erupted. Except for the Children's Crusade of 1212, these were all accompanied by violent antisemitism. It is not known why 1212 was the exception. The literate classes were hostile to this particular unauthorised crusade but mytho-historicised it so effectively that it has become one of the most evocative verbal accounts from the Middle Ages and this has remained in European and American imagination. The term "Children's Crusade" requires clarification in that neither word "children" – in Latin pueri – nor the word "crusade" – described in Latin as peregrinatio, iter, expeditio, or crucesignatio – are a completely accurate or inaccurate description.[56] Although, there are a numerous written sources they are of doubtful veracity. They differ on dates and details and utilise mytho-historical motifs and plot lines.[57] At the time, clerics used the sexual purity and "innocence" of the pueri as a critique of the sexual misbehaviour seen in the formal crusades. This misbehaviour was considered to be the source of God's anger and the ultimate reason for the failure of campaigns.[58]
Ethnic identity was a social construct in medieval times. In the opinion of Christians, all humanity shared descent from Adam and Eve. Differences were cultural, rather than racial. Chroniclers of the First Crusade often use the ethno-cultural term inherited from the Greeks of antiquity of barbarians or barbarae nationes. This is best understood in medieval terms as a differentiator from the self-identity of the word Latins, that the crusaders used for themselves.[59]
There are no specific crusading references in the 11thcentury chanson de geste
Mohammad was insulted.[62] Historian Jean Flori argues that to self-justify Christianity's move to war, their enemies needed to be ideologically destroyed.[63]
The Turks were respected as opponents in the Gesta Francorum despite some negative representations. Turks and the Franks were considered to share a knightly lineage. Aumont in the Chanson d'Aspremont and some others were represented as equals, even as far as being seen as following the chivalric code. By the time of the Third Crusade there is evidence of a class division within the nobility in both camps. They shared an identity that overcame religious and political differences. The two elites were separate from their common coreligionists who had other loyalties. Epics increasingly included conversions to Christianity. At a time when the crusading movement was being defeated militarily this offered the promise of a successful solution to the conflict.[64]
Numerous poets went on crusade. Theobald I of Navarre, Folquet de Marselha, and Conon de Béthune all wrote songs. Other leading crusaders provided patronage for poets. So poets extolled the values of the nobility.[65] These were feudal in nature and crusading was represented in these terms. The Holy Land was God's, this had been stolen and his Christian vassals was fight for its restoration.[66] The rule by Muslims of lands that had once been held by Christians was seen as theft and the mistreatment of Christians demanded revenge. Islamic polities' own self perception led them to the opposite view and violent resistance to the restoration of Christian governance.[67]
Decretists elaborated on this, and Aquinas refined it in the 13thcentury.[69] In the late 11th and early 12thcentury the papacy became a unit for organized violence in the Latin world order, equivalent to other kingdoms and principalities. This required what were partly inefficient mechanisms of control that mobilised secular military forces under direct control of the papacy.[70]
The sanctification of war developed from 1159 when fairly permanent conflict with Islam in the Mediterranean began with the encouragement of
At the Council of Clermont, Urban II laid the foundation of the crusading movement. The catalyst was an embassy from the Byzantine Emperor Alexios I Komnenos to the earlier Council of Piacenza, requesting military support in his conflict with the Seljuk Empire. These Turks were expanding into Anatolia and threatening Constantinople. Urban's two expressed objectives for the campaign were freeing Christians and the Holy Sepulchre – the tomb of Christ in Jerusalem – from Muslim control[72].[2]
The military vulnerability of the settlers in the East required further supportive expeditions throughout the 12th and 13th centuries. In each generation, these followed the pattern of a military setback in the East, followed by a request for aid, and then crusade declarations from the papacy.[73]
12th century
The first century of crusading was simultaneous with the
troubadours Marcabru and Cercamon wrote songs with themes called sirventes and about absent loves called pastorela. Crusading became the subject of songs and poems rather than creating a new genre. Many songs about the third and fourth crusades remain, written by troubadours, and their northern French Trouvère and German Minnesänger equivalents.[75] Crusade songs served multiple purposes. They provided material, variations on courtly love, allegories, and paradigms. Through song audiences learnt about crusading in a way unmediated by the Church. These songs reinforced the nobility's identity and its position in society. They also provided for the expression of injustice and criticism of mismanagement when events did not go well.[76]
The First crusade's success was astonishing and seen as only possible through God's will.
Pope Calixtus II was another with Spanish experience. In 1123, He proposed that crusading should be conducted in both Iberia in the Levant with Canon XI at the First Council of the Lateran. This led to the campaign by Alfonso the Battler against Granada in 1125.[28][78]
Strategically, the crusaders could not hold Jerusalem in isolation, which led to the establishment of other western polities known as the Latin East. Even then, these required regular defensive expeditions, supported by the developing military orders. The movement expanded into Spain with campaigns in 1114, 1118, and 1122. Eugenius III he drew ideological links between fighting the Wends, the reconquest of Spain and the Second Crusade. The crusade in the East was not a success, which left the movement at the lowest ebb that it would be until the 1400s. There were still three campaigns in Spain, and in 1177 one in the East, but the movement remained diminished until news of the defeat at the hands of the Muslims in the Battle of Hattin created consternation throughout Europe and reignited enthusiasm.[28]
From the latter part of the century, Europeans adopted the terms crucesignatus or crucesignata, meaning "one signed by the cross". Crusaders identified themselves by attaching cloth crosses to their clothing. This fashion derived from the biblical passages in Luke 9:23, Mark 8:34 and Matthew 16:24 "to carry one's cross and follow Christ".[81][82] Through this action, a personal relationship between Crusaders and God was formed. This was a mark of the crusader's spirituality. Anyone could become a crusader, irrespective of gender, wealth, or social standing. This was known as an imitatio Christi, an "imitation of Christ", a sacrifice motivated by charity for fellow Christians. Those who died campaigning were martyrs.[83]
13th century
Crusade
Salimbene saw themselves as ordo parvulorum – an "order of little ones" amongst a revivalist enthusiasm and a spirit of apocalypse. The Austrian Rhymed Chronicle added apocalyptic elements of mytho-history to the Children's Crusade. In 1213, Innocent III called for the Fifth Crusade by announcing that the days of Islam were over.[85]
Propaganda
The crusading movement brought together supporters within papal circles, monastic orders,
troubadours were hostile following the Albigensian Crusade in their homeland, but songs about the crusades gained popularity. Books, churches, and palaces included visual representations that contributed to the dissemination of information. Church art and architecture, including murals, stained glass windows, and sculptures, often depicted themes related to the movement.[87][88] Crusading themes featured in literary works include include romances, travelogues like Mandeville's Travels, poems such as Piers Plowman and John Gower's Confessio Amantis, and works by Geoffrey Chaucer.[89][90][91][92] Nationalism was largely absent. Instead great men were praised, such as Charlemagne and members of leading families.[93]
Institutional reform
From 1198 when he was elected pope, Innocent III reformed the ideology and practices of crusading. He created a new executive office to organise the Fourth Crusade. In each province of the Church he appointed executors and utilised freelance preachers such as
Academic views on the breadth of the crusading movement are varied. Riley-Smith excludes popular crusades by definition, while Gary Dickson has produced in depth research.
Nicholas of Cologne who used charisma when recruiting large followings.[100]
Early century
Cardinal Hugo Ugolino of Segni led teams of preachers in Tuscany and northern Italy between 1217 and 1221. He played a part in loosening the church funding and crusade recruitment rules by using five percent income tax on the Church known as the "clerical twentieth" to pay for the mercenaries who joined the Fifth Crusade and for grants to crucesignati.[101] He took the name Pope Gregory IX when elected pope in 1227.[102] In 1239 Gregory IX excommunicated Frederick II when the emperor attempted to expand into papal territory. In 1241 Frederick threatened Rome, so Gregory deployed the crusading tools of indulgences, privileges, and taxes against him.[103][104].
Second Council of Lyons began the gathering of ideas to improve crusading organisation and finance. This demonstrated the resilience that would enable the movement's continuing existence.[107]
Criticism
Early criticism of crusading and the conduct of crusaders is evident. While the concept itself was seldom questioned in the 12th and 13th centuries, there were vigorous objections to crusades targeting heretics and Christian secular powers. The assault on Constantinople during the Fourth Crusade and the diversion of resources against Church enemies in Europe, such as the Albigensian heretics and the Hohenstaufen, drew condemnation. Troubadours in southern France expressed discontent with expeditions, lamenting the neglect of the Holy Land. The behavior of participants was seen as falling short of the expectations of a holy war, with chroniclers and preachers decrying instances of sexual immorality, greed, and arrogance. Western Europeans attributed failures and setbacks, such as those during the First Crusade and the defeat of the kingdom of Jerusalem at Hattin by Saladin, to human frailty. Gerhoh of Reichersberg linked the shortcomings of the Second Crusade to the arrival of the Antichrist and accused the movement of fostering increased puritanism.[108][109]
In response to criticism, the movement implemented ceremonial processions, calls for reform, bans on gambling and extravagance, and restrictions on the participation of women. The Würzburg Annals condemned the conduct of the crusaders, attributing it to diabolical influence. The defeat of Louis IX of France at the Battle of Mansurah in 1250 triggered debates on crusading in sermons and writings, including Humbert of Romans's work De praedicatione crucis—concerning the preaching of the cross. Humbert raised doubts about the method of forcible conversion.[110]
The expense of maintaining armies resulted in taxation, a notion vehemently opposed by
Roger Wendover, Matthew Paris, and Walther von der Vogelweide. Critics expressed apprehensions regarding Franciscan and Dominican friars exploiting the vow redemption system for monetary benefits. While the peaceful conversion of Muslims was considered a possibility, there is no indication that it reflected the prevailing public sentiment, as the ongoing crusades suggest otherwise.[111]
Later century
The triumph of the Egyptian Mamluk in the Holy Land plunged the crusading movement into turmoil. Despite successes in Spain, Prussia, and Italy, the loss of the Holy Land remained irreparable. This crisis encompassed both a crisis of faith and military strategy, deemed religiously disgraceful by the Second Council of Lyon.[112]
Prominent critics such as Matthew Paris in Chronica Majora and Richard of Mapham, the dean of Lincoln, voiced notable concerns at the council. The military orders, especially the Teutonic Order, faced censure for their arrogance, greed, luxurious lifestyles funded by their wealth, and inadequate deployment of forces in the Holy Land. Internal conflicts between the Templars and Hospitallers, as well as among Christians in the Baltic, hindered collaborative efforts. The Church perceived military actions in the East as less effective due to the independence of these orders and their perceived reluctance to engage in combat with Muslims, with whom critics believed they maintained overly cordial relations. A minority perspective, advocated by Roger Bacon and others, argued that aggressive actions, particularly in the Baltic, impeded the conversion efforts.[113]
The movement continued to exhibit traits of innovation, commitment, resilience, and flexibility by consolidating methods of organisation and finance, which facilitated its survival.[107] General opinion did not consider the loss of the Holy Land as final, only later when the Hundred Years' War began in 1337 did hopes for recovery fade.[112] One of Pope Gregory X's objectives was the reunification of the Latin and Greek churches, which he viewed as essential for a new crusade. At the Second Council of Lyon, he demanded the Eastern Orthodox delegation accept all Latin teaching. In return, Gregory offered a reversal of papal support for Charles I of Anjou, the king of Sicily, to meet the Byzantines' primary motivation of the cessation of Western attacks. However, there was little interest from European monarchs, who were focussed on their own conflicts.[112] Gregory created a complex tax gathering system for the funding of crusading, dividing Latin Christendom in 1274 into twenty-six collectorates. Each of these was under the direction of a general collector who further delegated the assessment of tax liability to reduce fraud. The vast amounts raised by this system led to clerical criticism of obligatory taxation.[114]
14th century
Between the councils of Lyon in 1274 and Vienna in 1314, there existed over twenty treatises concerning the recovery of the Holy Land. These were instigated by Popes who, following the lead of Innocent III, sought counsel on the matter. This led to unfulfilled strategies for the blockading Egypt and possible expeditions to establish a foothold that would pave the way for full-scale crusades with professional armies. Discussions among writers often revolved around the intricacies of Capetian and Aragonese dynastic politics. Periodic bursts of popular crusading occurred throughout the decades, spurred by events like the Mongol victory at Homs and grassroots movements in France and Germany. Despite numerous obstacles, the papacy's establishment of taxation, including a six-year tithe on clerical incomes, to fund contracted professional crusading armies, represented a remarkable feat of institutionalisation.[115] The 1320 pastores of the Second Shepherds' Crusade was the first time that the papacy decried a popular crusade.[116]
Beginning in 1304 and lasting the entire 14thcentury, the Teutonic Order used the privileges Innocent IV had granted in 1245 to recruit crusaders in Prussia and Livonia, in the absence of any formal crusade authority. Knightly volunteers from every Catholic state in western Europe flocked to take part in campaigns known as Reisen, or journeys, as part of a chivalric cult.[117] Commencing in 1332, the numerous Holy Leagues in the form of temporary alliances between interested Christian powers, were a new manifestation of the movement. Successful campaigns included the capture of Smyrna in 1344, the Battle of Lepanto in 1571, and the recovery of territory in the Balkans between 1684 and 1697.[118]
After the Treaty of Brétigny between England and France, the anarchic political situation in Italy prompted the curia to begin issuing indulgences for those who would fight the merceneries threatening the pope and his court at Avignon. In 1378, the Western Schism split the papacy into two and then three, with rival Popes declaring crusades against each other. The growing threat from the Ottoman Turks provided a welcome distraction that would unite the papacy and divert the violence to another front.[119] By the end of the century, the Teutonic Order's Reisen had become obsolescent. Commoners had limited interaction with crusading beyond the preaching of indulgences, the success of which depended on the preacher's ability, local powers' attitudes, and the extent of promotion. However, there is no evidence that the failure to organize anti-Turkish crusading was due to popular apathy or hostility rather than to finance and politics.[120]
15th century
Gabriel Condulmaro, hailing from Venice, ascended to the papal throne as
Felix V as pope, Eugenius retained support and continued his policies until his death in 1447. The fall of Constantinople to Mehmed II in 1453 marked the beginning of a twenty-eight-year expansion of the sultanate.[121][122]
