Crusade
The crusades of the Middle Ages were armed pilgrimages preached by the pope, financed and carried out by the nobility of Occident. They fitted in the Christian holy war of S. These Christian military forwardings were preached in the name of the release of Jerusalem, conquered with the Arab Abbassides by the Turkish S in 1078.
The First crusade begins in 1095, that is to say seventeen years after the Turkish invasion. It was the only crusade known as popular, i.e. made up of thousands of pilgrims pedestrians. It was also the occasion for the pope to occupy the nobility in its power struggle with it.
They were held between 11th and 13th centuries. They found their origin in the will of the Christian of Occident to take again Jerusalem with the Turkish S, but the identity of emblem between Turks and Arabs - the crescent - did not make it possible illiterate lords to distinguish from/to each other, from where a drive out-crossed which settled in the duration. Later, of the crusades were launched against the other pagan nations of the Europe, such as the Lithuania, and against the heretics (the Croisades against Hussites, 1418 - 1437). The Reconquista is formally a crusade.
The term of crusade
At the end of the 11th century appear the armed pilgrimages, whose Latin name “ iter hierosolymitanum ” (voyage from Jerusalem) does not distinguish them from the individual pilgrimages. It is under this name which the contemporaries could indicate what we call the first crusades, or under that of peregrinatio , “pilgrimage”. Later are also employed the terms of auxilium ground sancte , “assistance with the Holy Land”, expeditio , transitio, “general passage” (national armies) and “particular passage” (specific, particular forwardings).
The term of crusade appears only tardily in French: The Trésor of the French language makes go up the expression “oneself cruisier” (to cross) with the Vie of St Thomas the martyr of Guernes of Bridge-Holy-Maxence gone back to 1174, and the term of “crusade” to the Chroniques of Chastellain gone back to before 1475, noting that it is about a substitute of close terms such as “crossing”, “croisery” or “cruising” which are older, without one being able to announce them before the end of the 12th century; The historical Dictionary of the French language notes a first appearance of the word about 1460 and also notes that it derives from “crossing”, that one meets before the end of the 12th century. However, former French “croiesery” appears in the chronicle of Robert de Clari during the Fourth crusade (1204) while one finds Spanish cruzada in a charter in Navarre of 1212. Actually, all these terms are substantives of the adjective crucesignatus , cross (literally, marked by the cross) which appears to him in the chronicle of Albert of Aix (undoubtedly written, for its first part, since 1106) or of the verb crucesignare , to take the cross, which is frequent at the 12th century.
It is thus clear that what we call “first crusade” was not called thus by its contemporaries. From the Moslem point of view, the crusades are not perceived besides like an innovation, but like the continuation of the fight against the Roman Empire of the East, which had lasted for several centuries. However, it is as obvious as the contemporaries were very early aware that the crusade was not a simple pilgrimage armed nor an military operation like the others but well a different reality, combining the characteristics of the pilgrimage with Jerusalem with the requirements of a war for the defense of the faith.

The conquest of the Palestine by the Arab S (Jerusalem was taken in 638) hardly affected the Pèlerinage towards the Christian holy places, such as Jerusalem, Bethlehem, and Nazareth. However in 1009 the Caliph fatimide of the Cairo, Al-Hakim, made destroy the the Holy Sepulchre. Its successor allowed the Byzantine Empire to rebuild it, and the pilgrimage was again authorized.
With the defeat of the Byzantine empire at the time of the Battle of Manzikert in 1071, the Turkish S Seldjoukides make captive the emperor Romain IV, the Byzantine patriarch, then take Jerusalem in 1078. Among the arguments called upon in particular by Pierre the Hermit, the main thing is that the Turkish S had prohibited with the Christian pilgrims the access to the Holy City. However, Robert Mantran counts several pilgrimages, including six between the years 1085 and 1092, which were held without the sources not mentioning particular difficulties.
With the council of Pleasure of June 1095, the ambassadors of the Byzantine emperor Alexis Comnène claim with the Westerners a military aid to fight against the Turks. The letter gone back to 1095 addressed by Alexis Comnène to the count Robert II of Flanders, calling the Help! after a apocalyptic description of the situation of the Christians under the Moslem yoke (…) is a forgery. Alexis Comnène hoped however indeed which the Occident sends to him of the soldiers that it could have engaged as mercenaries to continue his operations of reconquest in Asia Mineure.
In parallel, the Roman Church tries to leave the crisis which she underwent at the beginning of the 10th century. The Clergé lost of its prestige: it lends itself to the Simonie S and the Nicolaïsme and thus saps the moral authority of the Church. The primary goals of the council of Clermont are thus to try to continue the work started by Gregoire VII in order to restore a certain rigor: Urbain II is resulting from the movement clunisien and reaffirms the great principles enacted by its predecessors: the “Truce of God” and the “Peace of God”. The last years of the 11th century are a succession bad harvests and the people, encouraged by certain preachers, see there a divine punishment and a call to penitence. The call to the crusade is the occasion to weld Christendom in a crowned search and to offer to the lords the occasion “to purify their heart”. Indeed, a plenary indulgence (discharge of all the sins) is granted to those which undertake the voyage. It makes it possible moreover to restore a certain peace by offering a discharge system to the quarrelsome impulses of noble Europeans who can thus appease their thirst for conquest and wealth very of ensuring the safety of their heart.
Reputation and evaluation
In Western Europe, the crusades were regarded traditionally as heroic efforts, but all the historians are not agreement on this vision of the things. In the Muslim world, the crusades are regarded as cruel and wild attacks Christians against the Islam. Currently, certain speeches of integrist Islamic use the word crusade in this context as for the actions of the West against them. The Orthodoxie sees also the crusades like attacks by the West, because of the bag of Constantinople during the fourth crusade in 1204.There is an interesting agreement between the terms crusade and Jihad . In the West the term crusade has positive connotations (for example in policy one could use the formula crusade against drugs ) whereas the term jihad has negative connotations, associated with a fanatic Holy war. In the Muslim world, the term jihad has positive connotations which also include a direction of personal and spiritual fight against oneself , whereas the term crusade has the negative connotations described above.
One did not underline enough the role of Norman/Vikings or rather of their descendants in the organization, the development and the control of the crusades: Godefroy de Bouillon and Robert de Flandres were directly parents or combined to the Normans big families. After their recognition of papal sovereignty, the Norman ones of the South of Italy and Sicily played a political role and " technique" essence. Richard Lion-hearted is well-known… There was a guard " besides; varègue" (Scandinavians of Russia) near the Byzantine emperor since the 9° century. Varègues, then the Norman ones of Southern Italy had launched attacks against Constantinople in IXe and Xe S. and still in 1043.
Actually all the actions of cross were not heroic. They made atrocities not only against the Musulmans but also against the Juif S and the Christian. For example the fourth crusade never arrived to Palestine, but instead of that it put at bag Constantinople, the capital of the Christian Byzantine empire. Many relics and stolen objects in Constantinople are still with the the Vatican, Venice, and elsewhere. This crusade worsened resentments between orthodoxy and Catholicism. The Byzantine Empire recovers finally Constantinople in 1261, but its power was not found, and the empire was overcome by the Ottoman Empire in 1453.
Chronology of the crusades
Crusade of Leon IX against the Norman ones, 1053
By definition, a crusade is a military forwarding made in a religious intention. The military forwarding of the pope Leon IX, in June 1053, against the Norman ones which occupied the south of Italy, can be considered, for this reason, like indeed a Christian crusade.To the call of the inhabitants of the town of Bénévent, besieged by the Norman ones, with at their head Richard count d' Aversa, the pope Leon IX goes to Germany to request military forces from the emperor Henri III. This last convenes in Worms in December 1052 a Diet whose members grant to him with against heart, 3000 souabes, the best soldiers of the Germanic empire. Leon IX then multiplies the diplomatic steps with the empire of Byzance which in its turn offers to him the support of the Argyros general and his army. After having excommunicated all the Norman ones of Italy, Leon IX decides definitively to drive out them. He succeeds in for his crusade, of which he will take the command personally, also raising many counts and Italian barons who will take the weapons in the name of the cross. The Norman ones had at their head, Onfroi de Hauteville which was car proclaimed count de Pouille and had made Melfi its fortified town. He was assisted by all his brothers and half-brothers whose among the latter, Robert de Hauteville says Guiscard, as well as the many Breton ones. The battle took place with Civitate in Pouille on June 23rd, 1053 close to the Fortore river. In spite of the very clear numerical superiority of the crusaders, Hauteville will be victorious. The pope will be held during nearly one year by the Norman ones in the town of Bénévent which it will leave on a stretcher to die in Rome a few weeks later in 1054.
First crusade (1096 - 1099)
See also: First crusade
In 1096, the Byzantine emperor Alexis I {{er}} Comnène required of the Occident to help it to defend its empire against the Seldjoukides. This request joined the concerns of the monk Pierre the Hermit and of the pope Urbain II (pontificate of 1088 with 1099) which during a public sermon on November 27th 1095, tenth day of the Concile of Clermont, called with the weapons all the Chrétienté, a call to the defense of the faith threatened by the new Moslem invasion and the taking possession of minor Asia by the Turks: of Nicée whose Islam had taken control 14 years earlier, one could at any moment surprise Constantinople. The cry of “God wants it! ” (“ God Li volt ! ”) became the general rallying cry, and the pope asked the soldiers to mark sign of the cross. This war would be regarded as Pénitence for the crusaders, a plenary Indulgence. The crusaders walked towards Jerusalem, several cities Christian on their road were put at bag. In 1099, they seized Jerusalem, and all the inhabitants still in the city were massacred. Following the first crusade, several small States were created, in particular the Royaume of Jerusalem, which remained during one century. Antioche and Édesse was also taken again.
Godefroy de Bouillon refused to be appointed king of the Kingdom of Jerusalem. He says: " I would not carry a gold crown, where Christ carried a crown of épines". He was then the Solicitor of the Holy Sepulchre, that is to say " advocatus Sancti Sepulchri". A few months later after the death of Godefroy his/her brother Baudouin, Count d' Édesse, were made crown King de Jérusalem by the Latin patriarch of the city.
Second crusade (1147 - 1148)
See also: Second crusade
Following the resumption of the county of Édesse by the Moslems in 1144, the pope Eugene III puts all his zeal to organize a new crusade the first December 1145. For that, he asks his Master Bernard de Clairvaux, one of the most estimated most famous men and Christendom of the time, to preach this crusade. Bernard de Clairvaux convinces, by promising that those which would take the cross would see their exonerated sins, of many noble French of which Louis VII (king de France) with Vézelay on March 31st 1146 at the time of a memorable speech. It is told that at the end of this assembly, the population claimed as well cross as the fabric had suddenly missed and than Bernard himself gave his dress so that crosses there are cut. He made in the same way with Conrad III (Germanic emperor) which he succeeds in convincing on December 25th of this same year.
But the catch of Edesse is not the only cause of the crusade, second is that Louis VII wanted expier a crime whose memory tormented it: the fire of a church in which a certain number of people had sought refuge. The two armies, Frenchwoman and allemande, join together more 200 000 cross.
Conrad III starts from Ratisbon in May 1147 according to bank of the the Danube in direction of Edesse. The French with at their head Louis VII leave Paris later one month, that is to say in June 1147, by the same way as the Germans. First problem: The army of Conrad was extremely large and heterogeneous: a great part was not in fact not made up soldiers, but of civilians who ensured the support of the army in various ways; there were even poor people and criminals, who had crossed to be made forgive their sins and ensure their safety in the eternal life. It is thus hardly surprising that the Germanic emperor had little control on such an army. Indiscipline in the German army causes incidents in Balkans. But of other problems will occur while arriving at Constantinople. There, the Byzantine emperor Manuel Ier Comnène imposes to them an oath of vassalage (Manual required initially that the French Army, just as the German army, not carry not reached to its empire and its goods. It then required that the cities conquered by the crusaders are given to him and sent even a list of the cities concerned, in order to avoid a repetition of the misunderstandings which had occurred at the time of the first crusade.) But in spite of alliance germano-Byzantine, Conrad III and Louis VII refuse. They thus lose the support and the assistance of the Byzantines who refuse to supply them, which will result in to complicate the crossing of minor Asia and to even lengthen it a little. Moreover, the emperor of Constantinople, anxious to see the important manpower crossed with the doors of its city, the press to cross the Bosphorus to join Asia. In the same way, relations enveniment between French and Germans who, getting along more, decide to walk on separately. The army of Conrad falls into a Turkish ambush. This event enormously discourages German pilgrims who reconsider their steps. Conrad is reconciled with Manuel which proposes Byzantine vessels to him which will take them along to Acre. Louis VII and his army follow the littoral, but are made attack in the valley of the Meander, close to Dorylée where Louis gives up part of his troop. From there, it embarks with its knights towards Antioche. After one brief moment spent with Antioche, it joined Conrad in Jerusalem. It should be known that at this time from forwarding, the three quarter of the army disappeared. Their finished pilgrimage, some set out again in Europe; the two sovereigns let themselves involve by the barons of Jerusalem in a forwarding against, not Édesse as envisaged, but Damas. The seat of this city will last only four days (24 July 28th 1148) to which succeeded a defeat of the Christians.
They returned then to occident where the failure of the crusade caused deep movements: the prestige of Louis VII is strongly started, but the excellent regency of Suger, which was seen entrusting the regency of the frank kingdom, knew to preserve at the kingdom its power. The failure of this second crusade will be allotted by the popular opinion to excesses of sins of the crusaders.
Third crusade (1189 - 1192)
See also: Third crusade
In 1187, Saladin took again Jerusalem. The pope Gregoire VIII, sucessor of Urbain III, which one claimed died following the shock felt with this news, launched a new crusade, which was carried out by several of the most important chiefs of Europe: Richard of Poitou, future Richard Heart-of-Lion takes the cross the first, soon followed by Henri II of England, Philippe Auguste and, with the pritemps, by Frederic I {{er}} Barberousse, Germanic Roman Emperor. In same time, the naval fleet of Guillaume II of Sicily sets sail towards the outposts of Tripoli, Antioche and Tyr to help them to resist against the attacks of the sarasins. The fights Franco-English and the brutal death of Henri II delay the departure of king de France until 1190, whereas cross fleets left already Northern Europe, England and Flanders since May 1189 and take again Silves with the Moors on the way. The same month, Frederic leaves Ratisbon with more the large army crossed ever gathered.
The situation in Syria is alarming: the colonists between-tear between the partisans of Conrad de Montferrat, victorious of Saladin with Tyr, and the faithful ones of the king de Jérusalem Guy de Lusignan, person in charge of the defeat of Hattîn. Guy all the same started to besiege Acre with a small troop in August 1188, destination of the Western fleets. After a triumphal crossing of Europe and minor Asia, Frederic accidentally drowns in water of the Sélef (Asia Mineure) in 1190 and most of its Germans turned over to Europe, the others reaching not without sorrow Acre in October. In July 1190, the French and English kings leave Vézelay together and spend the winter to Sicily, where they dispute on many political and personal subjects. Philippe turned over at his place in 1191 after the crusaders had taken again Acre with the Moslems in July of the same year, while Richard Lion-hearted, large war leader, remained only, beat the Moslems with Arsouf. Arrived at Jaffa in September, it spends the year to Palestine of the south, period during which it makes rebuild Ascalon to strengthen the southernmost borders of the Royaume of Jerusalem. By twice (in December 1191 then in June 1192), he arrives a few kilometres from Jerusalem, but could not take again the Holy City. After having signed a treaty with Saladin, it sets out again for England in October 1192 while Philippe Auguste benefitted from his absence to remove many continental territories with his brother Jean without Ground. In 1194, the order of Trinitaires is founded by Jean de Matha for the repurchase of the prisoners captive of the Moslems. It is later confirmed by the Pape Innocent III in the bubble divine Operante dispositionis .
Fourth crusade (1200 - 1204)
See also: Fourth crusade
The fourth crusade was called by the pope Innocent III in 1202 and by Foulques de Neuilly, but it is diverted by the Vénitiens which finance it and which direct it against the Byzantine Empire Christian, in order to increase their possessions in the sector, whereas the crusades had been launched in the aim of protection also Byzance. Benefitting from the internal disorders of the empire, the crusaders were combined with Alexis IV, the son of the Byzantine emperor deposited Isaac II, to set up the Latin Empire of Constantinople). The crusade concludes with the bag from Constantinople in 1204, the creation of new Latin states in Greece, the secession of Épire and Trébizonde, Byzantine continuity being ensured by the Empire (strong tiny room) of Nicée.
The original spirit of the crusades from now on had died, and the successive crusades can be regarded as the will of the Pope to dominate the secular capacity by diverting its military power towards Palestine and the Syria.
Albigensian Crusade (1209)

The Albigensian Crusade was launched in 1209 to counter the divergent minority Cathare (regarded as Hérétique) in the south of France. The crusade is launched by Innocent III, in spite of the reserves of the king de France Philippe Auguste. This crusade is a defeat for the pontifical capacity which wanted to benefit from it to increase its capacity on the European sovereigns. Large gaining is the French royalty which fixes vast territories in the Occitanie without very beginning directly, the war being carried out for their own account by barons of north (Simon de Montfort). During this crusade an order of knighthood was created, the Order of the Militia of Jesus-Christ (1209), by the founder about the Preaching friars, Dominique de Guzman and the Foulques Bishop of Toulouse.

At the same time, other groups leave Germany and go towards the ports of Genoa and Marseilles. The chroniclers mention that some succeeded in embarking and that they were sold like slaves or died of hunger during the voyage. Some succeed in gaining Rome. The emperor Frederic II made hang some of the Marseilles traffickers compromised in the business (Provence formed then part of the Holy roman Empire Romain Germanique).
As for the name of crusade of the “children”, it would be in fact a literal translation of the Latin word “puer” not having in this context the direction of the word “child”. The crusade would have been in fact made up of the poor and peasants having been excluded from the economic revolution from the 12th century and believing firmly that God would support them in their company.

Assessment and consequences of the crusades in Europe
First great persecutions against the Jews
With many regards, the year 1096 marked a turning for the European Judaism. The call to the crusade of the pope Urbain II in 1095 did not encourage the crowd of faithful Christians to tackle the Jewish communities of the Rhine (indicated in Hebrew under the name of " Ashkenaz " אשכנז) but they was well victims. In margin of the official crusade, preachers indicated them with popular vindication. The Juif S were in front of the alternative to convert or to die as a martyr.Encircled by the stray (in Hebrew to' im תועים), without any hope, of the mothers and the fathers chose to cut the throat of their own children, with the image of Abraham ready to sacrifice his/her only son Isaac, rather than to see them apostasier.
A witness, Rabbi Solomon bar Siméon, reports as follows:
While passing by the villages where Jews were, they said one to the other: " here that we walk by long roads to the research of the house of idolatry and to draw revenge on the Ismaélite S, and here the Jews, whose ancestors killed it and crucifièrent it for nothing, which lives among us. We avenge for them initially, and erase to them number of the nations, which one does not remember any more of the name Israel, or although they are as us and believe in the wire of the impurity. "
Les epithet used here is not those of the Christians, but Rabbin which " speak in their nom"
Compared to those of Germany, the communities of France and England were, according to the Hebraic chronicles, relatively saved at the time of the second crusade (1146) thanks to the intervention of Bernard de Clairvaux. Bernard defines the position of the Church thus:
the Jews have the hope to be saved, because one day will come where their eyes will be dessilleront and where they will convert. The same does not apply for Islam from there: the Moslems will never convert. For them it is one language, that of the exterminating sword.However, of the attacks against the Jews, of the massacres, plunderings, the forced apostasies were held with Worms, Mainz, Bacharach and Würzburg, Strasbourg and Aschaffenbourg. At that time, the Jews of Germany still had the right to carry weapons. Rabbi Éphraïm bar Jacob of Bonn reports that the castle of Wolkenburg, emptied its inhabitants not Juifs and of his military garrison, was entrusted to the Jewish community of Cologne, of which the major part could thus be saved.
Four Hebrew chronicles treat tragic first and second crusades and their consequences for the Jewish communities:
- chronicles of Rabbi Solomon bar Siméon
- chronicles of Rabbi Eliézer bar Nathan
- the anonymity of Mainz
- " a book of the souvenir" of Rabbi Éphraïm bar Jacob of Bonn who relates to the second crusade

Military adaptations
The frank knights were confronted in the East with climatic conditions and unusual adversaries. The torrid climate and dryness, the sandy or rocky ground, the pouring rain of the autumn, put at severely tested men, equipment and mountings. The Moslem, fast riders and badgering with their arrows the knights, equipped slightly, incontestably had the advantage on the Western knights. Those adapted equipment and tactic, which enabled them to remain nearly two centuries in the East.
A certain number of adaptations aim at limiting the heating to the sun: several authors announce many deaths due to the Insolation. The heaume was often replaced by the iron hat, length Haubert by a shorter coat of mail, the haubergeon, or by the gambeson (stuffed clothing worn under the coat of mail, to deaden the shocks). In the same way, with the covers the armours and the horses cover, to limit the heating to the sun. The horses turcomans are also bought (or stolen) in great number, to replace the horses killed with the combat or died. The local armament, as excellent quality (the arms manufacturers of Damas had excellent reputation), also serves to replace the weapons which the European combatants lost or broke.
In a broader way, the use of the Turkish mass, which makes it possible to smash the parts of armor, spreads in Europe after the crusades. It involves the abandonment of the Heaume at flat top, replaced by the convex helmets, deviating the blows.
The principal military adaptations are located however in the tactics. The fatal effectiveness of the assembled archers, who often aimed at the horses of the Francs, pushed with a questioning of the combat based on research of the frontal shock. The more frequent recourse to the infantry, protecting the horses behind long shields, and with the archers and especially with the principal rafters, more powerful and precis which the archers, allowed to compete with the Moslem riders. Units of assembled principal rafters are also created, as well as units of indigenous light cavalry, the Turcopole S, very useful also for the information.
But the favorite tactics, the massive load creating the rupture of the enemy army, are not abandoned, and the heavy armament either. On the one hand, the heavy practices and expenditure in this armament made that it was difficult to give up them. In addition, the heavy armament generally ensured an unquestionable superiority Christian combatants in numerical inferiority. Lastly, by choosing the moment of the combat so that the combatants do not await of weapons under the sun, and so that the combat is short, Europeans had sometimes excellent results.
Cultural exchanges
The interest of the Western well-read men for Arab and ancient science is former to the crusades: The states resulting from the Spanish Marche are in direct contact with the Muslim world. their emancipation with respect to the frank empire pushes them to trade with the Califat of Cordoue. Thus as of 985 the Comté of Barcelona profits from a push of technical and cultural development. The monastic development and that of the Pèlerinage of Saint-Jacques-to-Compostelle will make it possible to fix written knowledge and to diffuse them in whole Europe. The kings of Navarre and León thus make maintain the roads and build bridges. Reception facilities for the pilgrims who flow per tens of thousands are organized along the ways of Saint-Jacob. Thus, the mathematician and clerk Gerbert d' Aurillac (938? - 1003) - more known as pope Sylvestre II - had brought back from Spain the figures known as “Arab” of Indian origin of which the Zero. The very strong development of the religious orders and the broad recourse to the monks Convers support the diffusion of the artisanal and agricultural techniques in the campaigns. It results from it a population increase and technique in occident at the 11th century which makes possible the crusades. However, they are the occasion to multiply and look further into this knowledge. With the crusades the scientific and philosophical spirit of Occident develops the study and the criticism of works arabo-Moslems. Robert Grossetête), Albert Large the (1200? - 1280), the first Roger Bacon) and Thomas d' Aquin), inter alia, take this route, without their step being attached more to the crusades only with the contacts with Spain and Sicily Moslem women.
