List of Crusades

The list of Crusades in Europe and to the Holy Land identifies those conflicts in the 11th through 16th centuries that are referred to as Crusades. These include the traditional numbered crusades and others that prominent historians have identified as crusades. The scope of the term crusade first referred to military expeditions undertaken by European Christians in the 11th, 12th, and 13th centuries to the Holy Land. The conflicts to which the term is applied has been extended to include other campaigns initiated, supported and sometimes directed by the Roman Catholic Church against pagans, heretics or for alleged religious ends.

This list first discusses the traditional numbered crusades, with the various lesser-known crusades interspersed. The later crusades in the Levant through the 16th century are then listed. This is followed by lists of the crusades against the Byzantine empire, crusades that may have been pilgrimages, popular crusades, crusades against heretics and schismatics, political crusades, the Northern Crusades, crusades in the Iberian peninsula, Italian crusades and planned crusades that were never executed. Comprehensive studies of the Crusades in toto include Murray's Encyclopedia, Stephen Runciman's A History of the Crusades, 3 volumes (1951–1954), and the Wisconsin Collaborative History of the Crusades, 6 volumes (1969-1989).

Crusades to the Holy Land (1095–1291)
The conflicts that are usually associated with crusades in the Holy Land begin with the Council of Clermont in 1095 and end with the loss of Acre in 1291. These include the numbered Crusades (First through Eighth or Ninth) with numerous smaller crusades intermixed. One of the first to view the Crusades as a movement was English historian Thomas Fuller (1608–1661), whose Historie of the Holy Warre (1639) identified crusades as the Holy War consisting of "Voyages," numbering One through Thirteen, plus a Last Voyage and two additional Holy Wars. These Voyages include the First through Eighth Crusades in current numbering. Shortly thereafter, French Jesuit Louis Maimbourg (1610–1686) published his Histoire des Croisades pour la délivrance de la Terre Sainte (1675), identify the First through Fifth Crusades. In his work The Crusades—An Encyclopedia, historian Alan V. Murray further explains the traditional numbering of crusades:

"It was in the eighteenth century that historians evidently first allocated numbers to individual crusades, from the first to the ninth. However, these numbers are neither consistent nor accurate. Of the identity of the First Crusade (1096—1099) there can be no doubt, but there is no consensus about numbering after the Fourth Crusade (1202–1204). The Crusade of Emperor Frederick II (1227–1229) is sometimes regarded as part of the Fifth Crusade (1217–1221) and sometimes as a separate expedition. This means that the term Sixth Crusade may refer either to Frederick II's crusade or to the first crusade of King Louis IX of France, which might also be called the Seventh Crusade. Consequently, each subsequent number after the fifth might refer to either of two different expeditions. The only absolutely clear method of designating individual crusades is by a combination of dates and descriptive terminology relating to participation, goals, or both, and this is the solution that has been adopted [here]. However, the names of the First, Second, Third, Fourth, and Fifth Crusades, which are at least unambiguous (if not accurate), have been retained, as they are now established by long tradition."

The list of the Crusades to the Holy Land from 1095 through 1291 is as follows.

First Crusade. The First Crusade (1095–1099) refers to the activities from the Council of Clermont of 1095 through the establishment of the Kingdom of Jerusalem and the battle of Ascalon in 1099. Sometimes segregated into the People's Crusade and the Princes' Crusade. Some accounts also include the Crusade of 1101 here. The original chroniclers of the First Crusade did not, of course, refer to it as such, or even as a crusade (as noted above). In the twelve Latin chronicles, the event is called, for example, the Deeds of the Franks or the Expedition to Jerusalem. Anna Komnene simply notes the arrival of the various armies in Constantinople, and Arabic historian ibn Athir calls it the Coming of the Franks. Thomas Fuller referred to it as Voyage 1 of the Holy Warre. It is unclear as to who first used the term, but it has been credited to Louis Maimbourg in his 1675 Histoire des Croisades. The term was certainly in common use by the 18th century as seen in Voltaire's Histoire des Croisades (1750–1751) and Edward Gibbon's History of the Decline and Fall of the Roman Empire (1776–1789). Thomas Asbridge's The First Crusade: A New History (2004) is among the standard references used today.

People's Crusade. The People's Crusade (1096) was a prelude to the First Crusade led by Peter the Hermit, the first of what is known as the Popular Crusades. It is sometimes regarded as an integral part of the First Crusade, with the Princes' Crusade as the second part. A standard reference is ''Peter der Eremite. Ein kritischer Beitrag zur Geschichte des ersten Kreuzzuges'' (1879) by pioneering German historian Heinrich Hagenmeyer (1834–1915). Peter and his crusade achieved a popular status in the 19th century through such works as Heroes of the Crusades (1869) by Barbara Hutton. The references shown above for the First Crusade generally cover the People's Crusade as well.

Crusade of 1101. The Crusade of 1101 (1101–1102) was also called the Crusade of the Faint-Hearted. Campaigns that followed the capture of Jerusalem in 1099 that were generally ignored by 18th and 19th century historians. Thomas Fuller nevertheless referred to it as Voyage 2 of the Holy Warre whereas Jonathan Riley-Smith considered it part of the First Crusade in his The First Crusaders, 1095-1131 (1997).

Norwegian Crusade. The Norwegian Crusade (1107–1110), also known as the Crusade of Sigurd Jorsalfar, king of Norway. More of a pilgrimage than a crusade, it did include the participation in military action, with the king's forces participation in the siege of Sidon. This crusade marks the first time a European king visited the Holy Land. This crusade is described in Heimskringla by Icelandic historian Snorri Sturluson.

Venetian Crusade. The Venetian Crusade (1122–1124), also known as the Crusade of Calixtus II. The Western participants from the Republic of Venice were regarded by Riley-Smith as First Crusaders, and the actions resulted in the capture of Tyre from the Damascene atabeg Toghtekin. This marked a major victor for Baldwin II of Jerusalem prior to his second captivity in 1123.

Crusade of 1129. The Crusade of 1129, also known as the Damascus Crusade, was begun by Baldwin II of Jerusalem after his captivity. The crusade failed in its objective to capture Damascus and is described by Syriac historian Michael the Syrian in his Chronicle (after 1195).

Second Crusade. The Second Crusade (1147–1150). After the disastrous siege of Edessa in 1144, the Western powers launched the Second Crusade, which accomplished little. Principal chroniclers of the event were Odo of Deuil, chaplin to Louis VII of France, who wrote his account De profectione Ludovici VII in Orientem and Otto of Freising who wrote Gesta Friderici imperatoris concerning the emperor Frederick Barbarosso. Referred to as the Second Crusade in Maimbourg's Histoire des Croisades... as well as Georg Müller's De Expedition Cruciatis Vulgo Von Kreutz Fahrten (1709). Thomas Fuller referred to it as Voyage 3 of the Holy Warre. The Wendish Crusade of 1147 (one of the Northern Crusades) is usually associated with the Second Crusade.

Crusader invasions of Egypt. The Crusader Invasions of Egypt (1154–1169) were attacks into Egypt by Amalric I of Jerusalem to take advantage of crises concerning the Fatimids. These activities eventually led to the fall of the Fatimids and the rise of Saladin and the Ayyubid dynasty.

Crusade to the East of Philip of Flanders. The Crusade to the East (1177) was a crusade led by Philip I, Count of Flanders that intended to invade Egypt, instead only mounting an unsuccessful siege of Harim.

Third Crusade. The Third Crusade (1189–1192). The Third Crusade was in response to the loss of Jerusalem to Saladin in 1187 and had significant English participation, under Richard I of England, as well as by the emperor Frederick Barbarossa and Philip II of France. To the English, it was known as the Itinerarium Regis Ricardi, the Itinerary of king Richard, and to the Germans as the expedition of Frederick, as described in Historia Peregrinorum (History of the Pilgrims). Thomas Andrew Archer's The Crusade of Richard I, 1189–1192 (1889) provides a comprehensive look at the crusade and its sources. Thomas Fuller referred to Frederick's portion as Voyage 4 of the Holy Warre, and Richard's portion as Voyage 5. The numbering of this crusade followed the same history as the first ones, with English histories such as David Hume's The History of England (1754–1761) and Charles Mills' History of the Crusades for the Recovery and Possession of the Holy Land (1820) identifying it as the Third Crusade. The former only considers the follow-on crusades to the extent that England participated.

Crusade of Emperor Henry VI. The Crusade of Henry VI (1197–1198) was also known as the Crusade of 1197 or the German Crusade. A crusade led by Holy Roman Emperor Henry VI as a follow-up to the Third Crusade. Although Henry died before the crusade began, it was modestly successful with the recapture of Beirut. Thomas Fuller referred to it as Voyage 6 of the Holy Warre.

Fourth Crusade. The Fourth Crusade (1202–1204) was also known as the Unholy Crusade. A major component of the crusade was against the Byzantine empire. Thomas Fuller referred to it as Voyage 7 of the Holy Warre. Charles du Cange, wrote the first serious study of the Fourth Crusade in his Histoire de l'empire de Constantinople sous les empereurs françois (1657). Geoffrey of Villehardouin was a knight and historian who wrote his eyewitness account De la Conquête de Constantinople (c. 1215) of the crusade and its aftermath. Voltaire did not call it a crusade in his Histoire des Croisades, instead calling it the Suite de la Prise de Constantinople par les Croisés. Jonathan Philips' The Fourth Crusade and the Sack of Constantinople (2004) is a standard reference today.

Fifth Crusade. The Fifth Crusade (1217–1221) was a failed attempt to recapture Jerusalem by first conquering Cairo. Critical original sources include Historia Damiatina by Oliver of Paderborn (died 1227) and Chronica Hungarorum by Joannes de Thurocz, compiled in the collection Gesta Dei per Francos (God's Work through the Franks) (1611) by Jacques Bongars. A standard reference is Reinhold Röhricht's Studien zur Geschichte des fünften Kreuzzuges (1891). Thomas Fuller referred to it as Voyage 8 of the Holy Warre.

Sixth Crusade. The Sixth Crusade (1228–1229), was also known as the Crusade of Emperor Frederick II. Sometimes regarded as part of the Fifth Crusade, it was an extension of that activity that involved little fighting. Jerusalem was nevertheless returned to Western hands by negotiation. Original sources include Chronica Majora (1259) by Matthew Paris and Flores Historiarum (1235) by Roger of Wendover, with Arabic sources that include Abu'l-Feda's Tarikh al-Mukhtasar fi Akhbar al-Bashar (1329). Modern histories include Röhricht's Die Kreuzfahrt Kaiser Friedrich des Zweiten (1228–1229) (1872). Referred to it as Voyage 9 of the Holy Warre by Thomas Fuller in his 1639 Historie. See also references under the Crusade against Frederick II (1220–1241) below.

Barons' Crusade. Barons' Crusade (1239–1241) was also referred to as the Crusade of 1239, or the Crusade of Theobald I of Navarre and the Crusade of Richard of Cornwall. Called for in 1234 by Gregory IX in his papal bull Rachel suum videns. Some successful expeditions recaptured portions of the Holy Land. First treated by R. Röhricht in his Die Kreuzzuge des Grafen Theobald von Navarra und Richard von Cornwallis nach dem heligen Landen. Thomas Fuller referred to it as Voyages 10 and 11 of the Holy Warre.

Crusade of Theobald I of Navarre. The Crusade of Theobald I of Navarre (1239–1240) was a crusade led by Theobald I of Navarre, also referred to as Thibaut of Navarre or Theobald of Champagne.

Seventh Crusade. The Seventh Crusade (1248–1254) is also known as the Crusade of Louis IX of France to the East, or Louis IX's First Crusade. Early works on this crusade include Primat of Saint-Denis' Roman des rois (1274) and Jean de Joinville's Life of Saint Louis (1309)''. '' Thomas Fuller referred to it as Voyage 12 of the Holy Warre. Grousset's Histoire des croisades... and Peter Jackson's Seventh Crusade, 1244–1254: Sources and Documents (2007) provide the necessary historical background.

Lord Edward's Crusade. Lord Edward's Crusade (1271–1272) was led by the future Edward I of England, and is also known as the Crusade of Lord Edward of England, the Ninth Crusade, or the Last Crusade. It is regarded by some as an extension of the Eighth Crusade. Edward, later King of England, was accompanied by his wife Eleanor of Castile, who came to his aid after an assassination attempt. Discussed as part of the Eighth Crusade by Joseph François Michaud in Volume 3 of his seminal Histoire des Croisades (1812–1822).

The only known reference to this is by Thomas Fuller in his Historie of the Holy Warre, where it is referred to as the Last Voyage.

Siege of Acre. The Siege of Acre (1291) marked the loss of the Holy Land to the Mamluks, typically identifying the end of the traditional Crusades. The anonymous Les Gestes des Chiprois (Deeds of the Cypriots) contains one of two eyewitness accounts of the siege.

Later Crusades (1291–1578)
After the fall of Acre, the crusades continued in the Levant through the 16th century. Principal references on this subject are Kenneth Setton's ''History of the Crusades, Volume III. The Fourteenth and Fifteen Centuries (1975), and Norman Housley's The Later Crusades, 1274-1580: From Lyons to Alcazar (1992) and The Crusading Movement, 1274–1700'' (1995). Barbara Tuchman's A Distant Mirror: The Calamitous 14th Century (1978) provides an interesting perspective on both the crusades and the general history of the era. A nineteenth-century reference often cited is Joseph François Michaud's Histoire des Croisades (1812–1822), translation by William Robson.

Shortly thereafter, Robert of Naples gave the crusade his support. The Venetians, however, renewed their treaty with the Catalans in 1331. By the summer, it was clear that the expedition had failed, and Walter returned to Brindisi, saddled with crippling debts.

Nothing beyond the defeat of the Byzantines at the naval battle of Settepozzi in 1263. Urban IV renewed his call for crusade in 1264, for the succor of the Morea, but to no avail. In 1281, Charles I of Anjou, Philip of Courtenay and the Venetians planned an incursion into the Byzantine Empire for the recapture of Constantinople.

Among those taking arms was Walter III of Brienne who wished to secure his claim to Taranto by virtue of his marriage to Elvira of Sicily. The need for the crusade ended with Markward's death in 1202.

It was conducted mostly by Germans from the Holy Roman Empire and Danes, and consisted of four parts: Crusades against the Livonians (1198–1209); Conquest of the Estonian Hinderland (1208–1226); Crusades against the Oeselians (1206–1261); Crusade against Curonians (1242–1267); and, Crusade against Semigallians (1219–1290). The principal original sources on these crusades are the Livonian Rhymed Chronicle and the Livonian Chronicle of Henry.

When peaceful means of conversion failed to convert the Livonians, bishop Berthold of Hanover arrived with a large contingent of crusaders in 1198.

Albert of Riga arrived the following year with a large force and in 1202, formed the Livonian Brothers of the Sword to aid in the conversion of the pagans. The Livonians led by Caupo of Turaida rebelled against the crusaders. Caupo's forces were defeated in 1206, and the Livonians were declared to be converted. Albert invaded with the forces of the Order in 1209, and the Livonians under duke Visvaldis were forced to submit to Albert.

They were led by Lembitu of Lehola who was killed along with Caupo of Turaida (fighting for the crusaders), at the 1217 battle of St. Matthew's Day, a crushing defeat for the Estonians. The Chronicle of Henry of Livonia relates how in 1226, papal legate William of Modena successfully mediated peace in the area.

Crusades against the Oeselians. The Crusades against the Oeselians (1206–1261).

Danish armies led by Valdemar II of Denmark failed in Saaremaa in 1206 and 1222, as did John I of Sweden in 1220. The Livonian Brothers of the Sword finally succeeding in converting the Oeselians to Christianity in 1226 after failing in 1216. After regressing, the Oeselians once again accepted Christianity in 1241, and signed a treaty in 1255.

After the defeat of the Estonians in 1126 and the Oeselians in 1241, the crusade moved against the Curonians who had attacked Riga in 1210 and 1228. Those in the north accepted peace with the Germans in 1230, but in the south the fighting continued. In 1260, the Curonians fought alongside the crusaders in the battle of Durbe, abandoning them in the midst of battle, allowing the Lithuanians to gain victory over the Livonian Order and Teutonic Knights. The Curonians were finally subdued in 1267 and the land partitioned. This was documented by Peter of Dusburg in his 1326 work ''Chronicon terrae Prussiae. ''

Crusade against Semigallians. The Crusade against Semigallians (1219–1290).

In 1219, this alliance was shattereded after a crusader invasion in Semigallia. Duke Viestards then formed an alliance with Lithuanians and Curonians. In 1228, Semigallians and Curonians attacked the main crusader stronghold, with the crusaders taking revenge and invaded Semigallia. In 1236, Semigallians attacked crusaders retreating to Riga after the battle of Saule, but by 1254, the Semigallians had been subdued by the Livonian Order. In 1270, the Semigallians joined Lithuanian Grand Duke Traidenis in an attack on Livonia and Saaremaa. During the battle of Karuse, the Livonian Order was defeated, and its master Otto von Lutterberg killed. In 1287, a force of Semigallians attacked a crusader stronghold in Ikšķile and plundered nearby lands.
