Fifth Crusade in the context of "Crusades"

Andrew II (Hungarian: II. András, Croatian: Andrija II., Slovak: Ondrej II., Ukrainian: Андрій II; c. 1177 – 21 September 1235), also known as Andrew of Jerusalem, was King of Hungary and Croatia between 1205 and 1235. He ruled the Principality of Halych from 1188 until 1189/1190, and again between 1208/1209 and 1210. He was the younger son of Béla III of Hungary, who entrusted him with the administration of the newly conquered Principality of Halych in 1188. Andrew's rule was unpopular, and the boyars (or noblemen) expelled him. Béla III willed property and money to Andrew, obliging him to lead a crusade to the Holy Land. Instead, Andrew forced his elder brother, King Emeric of Hungary, to cede Croatia and Dalmatia as an appanage to him in 1197. The following year, Andrew occupied Hum.

Although Andrew did not stop conspiring against Emeric, the dying king made Andrew guardian of his son, Ladislaus III, in 1204. After the premature death of Ladislaus, Andrew ascended the throne in 1205. According to historian László Kontler, "[i]t was amidst the socio-political turmoil during [Andrew's] reign that the relations, arrangements, institutional framework and social categories that arose under Stephen I, started to disintegrate in the higher echelons of society" in Hungary. Andrew introduced a new grants policy, the so-called "new institutions", giving away money and royal estates to his partisans despite the loss of royal revenues. He was the first Hungarian monarch to adopt the title of "King of Halych and Lodomeria". He waged at least a dozen wars to seize the two Rus' principalities, but was repelled by the local boyars and neighboring princes. He participated in the Fifth Crusade to the Holy Land in 1217–1218, but the crusade was a failure.

Pope Honorius III (c. 1150 – 18 March 1227), born Cencio Savelli, was head of the Catholic Church and ruler of the Papal States from 18 July 1216 to his death. A canon at the Basilica di Santa Maria Maggiore, he came to hold a number of important administrative positions, including that of Camerlengo. In 1197, he became tutor to the young Frederick II. As pope, he worked to promote the Fifth Crusade, which had been planned under his predecessor, Innocent III. Honorius repeatedly exhorted King Andrew II of Hungary and Emperor Frederick II to fulfill their vows to participate. He also gave approval to the recently formed Dominican and Franciscan religious orders.

The Sixth Crusade (1228–1229), also known as the Crusade of Frederick II, was (like the other Crusades) a military expedition to recapture Jerusalem and the rest of the Holy Land. It began seven years after the failure of the Fifth Crusade and involved very little actual fighting. The diplomatic maneuvering of the Holy Roman emperor and king of Sicily, Frederick II, resulted in the Kingdom of Jerusalem regaining some control over Jerusalem for much of the ensuing fifteen years as well as over other areas of the Holy Land. Frederick II's negotiations and power-sharing agreement and negotiation with envoys from al-Malik Al-Kamil of Egypt, which led to a shared Christian-Muslim governance situation in Jerusalem, made this Crusade different from the others (and some call it the only successful one). Frederick II carried out his maneuvers in 1228 while under excommunication from the Church by Pope Gregory IX.

John of Brienne (c. 1170 – 19–23 March 1237) was the king of Jerusalem from 1210 to 1225 and Latin emperor of Constantinople from 1229 to 1237. He was the youngest son of Erard II of Brienne, a wealthy nobleman in Champagne. John, originally destined for an ecclesiastical career, became a knight and owned small estates in Champagne around 1200. After the death of his brother Walter III, he ruled the County of Brienne on behalf of his minor nephew Walter IV, who lived in Italy.

The barons of the Kingdom of Jerusalem proposed that John marry their queen, Maria. With the consent of Philip II of France and Pope Innocent III, he left France for the Holy Land and married Queen Maria; the couple were crowned in 1210. After Maria's death in 1212 John administered the kingdom as regent for their infant daughter Isabella II; Maria's influential uncle, John of Ibelin, attempted to depose him. King John was a leader of the Fifth Crusade. Although his claim of supreme command of the crusader army was never unanimously acknowledged, his right to rule Damietta (in Egypt) was confirmed shortly after the city fell to the crusaders in 1219. He claimed the Armenian Kingdom of Cilicia on behalf of his second wife, Stephanie, in 1220. After Stephanie and their infant son died that year, John returned to Egypt. The Fifth Crusade ended in failure (including the recovery of Damietta by the Egyptians) in 1221.

Frisian involvement in the Crusades is attested from the very beginning of the First Crusade, but their presence is only felt substantially during the Fifth Crusade. They participated in almost all the major Crusades and the Reconquista. The Frisians are almost always referred to collectively by contemporary chroniclers of the Crusades and few names of individual Frisian crusaders can be found in the historical record. They generally composed a naval force in conjunction with other larger bodies of crusaders.

The first Frisians to participate in the First Crusade were part of the army which was led to the Holy Land by Godfrey of Bouillon and they are only mentioned in passing by Fulcher of Chartres, who mentions that the Frisian language was one of the many tongues spoken by the crusaders. William of Tyre, drawing his information from Fulcher, mentions Frisians as part of the troops led by Godfrey at the Siege of Antioch in 1097–1098. According to Albert of Aix, there was also a fleet of pirates, hailing from Denmark, Frisia, and Flanders and led by Guynemer of Boulogne, who assisted Baldwin of Boulogne at Tarsus.

Pelagio Galvani (c. 1165 – 30 January 1230, Portuguese: Paio Galvão Latin: Pelagius) was a Leonese cardinal, and canon lawyer. He became a papal legate and leader of the Fifth Crusade.

Born at Guimarães, his early life is little known. It is repeatedly claimed that he entered the Order of Saint Benedict but this is not proven. Pope Innocent III created him cardinal-deacon of Santa Lucia in Septisolio around 1206. Later, he was promoted to the rank of cardinal-priest of S. Cecilia (probably on 2 April 1211), and finally opted for the suburbicarian see of Albano in the spring of 1213. He subscribed the papal bulls between 4 May 1207 and 26 January 1230. He was sent on a diplomatic mission to Constantinople in 1213. During this two-year mission he attempted to close Orthodox churches and imprison the clergy, but this caused such domestic upset that Henry of Flanders, the Latin Emperor of Constantinople, reversed his actions which had caused the "tempest which held the city of Constantine in its grip", as noted a contemporary historian. Three years later he was elected Latin Patriarch of Antioch but his election was not ratified by the Holy See. He was dispatched in 1218 by Pope Honorius III to lead the Fifth Crusade at Damietta in Egypt, and made a poor strategic decision in turning down favourable peace offers made by the sultan al-Kamil. During his absence, the see of Albano was administer by Thomas of Capua.
