Foundation The Byzantines augmented their armies with
mercenaries from the Turks and Europe. This compensated for a shortfall caused by lost territory, especially in Anatolia. In 1095 at the
Council of Piacenza, Emperor
Alexios I Komnenos requested support from
Pope Urban II against the Seljuk threat. What the emperor probably had in mind was a relatively modest force, and Urban far exceeded his expectations by calling for the First Crusade at the later
Council of Clermont. He developed a doctrine of
bellum sacrum (Christian holy war) and—based mainly on Old Testament passages in which God leads the Hebrews to victory in war—reconciled this with Church teachings. Urban's call for an armed
pilgrimage for the liberation of the Eastern Christians and the recovery of the Holy Land aroused unprecedented enthusiasm in Catholic Europe. Within a year, tens of thousands of people, both commoners and aristocrats, departed for the military campaign. Individual Crusaders' motivations to join the crusade varied, but some of them probably left Europe to make a permanent home in the Levant. Alexios cautiously welcomed the feudal armies commanded by western nobles. By dazzling them with wealth and charming them with flattery, Alexios extracted oaths of fealty from most of the Crusader commanders. As his vassals,
Godfrey of Bouillon, nominally
duke of Lower Lorraine; the
Italo-Norman Bohemond of Taranto; Bohemond's nephew
Tancred of Hauteville; and Godfrey's brother
Baldwin of Bologne all swore that any territory gained which the
Roman Empire had previously held, would be handed to Alexios' Byzantine representatives. Only
Raymond IV, Count of Toulouse, refused this oath, instead promising non-aggression towards Alexios. The Byzantine general
Tatikios guided the crusade on the arduous three-month march to
besiege Antioch, during which the Franks made alliances with local Armenians. Before reaching Antioch, Baldwin and his men left the main army and headed to the Euphrates river, engaging in local politics and seizing the fortifications of
Turbessel and
Rawandan, where the Armenian populace welcomed him. Thoros, then ruler of this territory, could barely control or defend Edessa, so he tried to hire the Franks as mercenaries. Later, he went further and adopted Baldwin as his son in a power-share arrangement. In March 1098, a month after Baldwin's arrival, a Christian mob killed Thoros and acclaimed Baldwin as , the Byzantine title Thoros had used. Baldwin's position was personal rather than institutional, and the Armenian governance of the city remained in place. Baldwin's nascent County of Edessa consisted of pockets separated from his other holdings of Turbessel, Rawandan and
Samosata by the territory of Turkic and Armenian warlords and the Euphrates. As the Crusaders marched towards Antioch, Syrian Muslims asked Sultan
Barkiyaruq for help, but he was engaged in a power struggle with his brother
Muhammad Tapar. At Antioch, Bohemond persuaded the other leaders the city should be his if he could capture it, and Alexios did not come to claim it. Alexios withdrew rather than join the siege after
Stephen, Count of Blois (who was deserting) told him defeat was imminent. In June 1098, Bohemond persuaded a renegade Armenian tower commander to let the crusaders into the city. They slaughtered the Muslim inhabitants and, by mistake, some local Christians. The crusade leaders decided to return Antioch to Alexios as they had sworn to at Constantinople, but when they learnt of Alexios' withdrawal, Bohemond claimed the city for himself. The other leaders agreed—apart from Raymond, who supported the Byzantine alliance. This dispute resulted in the march stalling in north Syria. The Crusaders were becoming aware of the chaotic state of Muslim politics through frequent diplomatic relations with the Muslim powers. Raymond indulged in a small expedition. He bypassed Shaizar and laid siege to Arqa to enforce the payment of a tribute. In Raymond's absence, Bohemond expelled Raymond's last troops from Antioch and consolidated his rule in the developing Principality of Antioch. Under pressure from the poorer Franks, Godfrey and
Robert II, Count of Flanders, reluctantly joined the unsuccessful siege of Arqa. Alexios asked the crusade to delay the march to Jerusalem, so the Byzantines could assist. Raymond's support for this strategy increased division among the crusade leaders and damaged his reputation among ordinary Crusaders. The Crusaders
marched along the Mediterranean coast to Jerusalem. On 15 July 1099 Crusaders took the city
after a siege lasting barely longer than a month. Thousands of Muslims and Jews were killed, and the survivors were sold into slavery. Proposals to govern the city as an
ecclesiastical state were rejected. Raymond refused the royal title, claiming only Christ could wear a crown in Jerusalem. This may have been to dissuade the more popular Godfrey from assuming the throne, but Godfrey adopted the title
Advocatus Sancti Sepulchri ('Defender of the Holy Sepulchre') when he was proclaimed the first Frankish ruler of Jerusalem. In Western Europe an was a layman responsible for the protection and administration of church estates. The foundation of these three Crusader states did not change the political situation in the Levant profoundly. Frankish rulers replaced local warlords in the cities, but large-scale colonisation did not follow, and the conquerors did not change the traditional organisation of settlements and property in the countryside. The Muslim leaders were massacred or forced into exile, and the natives, accustomed to the rule of well-organised warbands, offered little resistance to their new lords. Western Christianity's
canon law recognised that peace treaties and armistices between Christians and Muslims were valid. The Frankish knights regarded the Turkic mounted warlords as their peers with familiar moral values, and this familiarity facilitated their negotiations with the Muslim leaders. The conquest of a city was often accompanied by a treaty with the neighbouring Muslim rulers who were customarily forced to pay a tribute for the peace. The Crusader states had a special position in Western Christianity's consciousness: many Catholic aristocrats were ready to fight for the Holy Land, although in the decades following the destruction of the large
Crusade of 1101 in Anatolia, only smaller groups of armed pilgrims departed for Outremer.
Consolidation (1099 to 1130) castle The Fatimids' feud with the Seljuks hindered Muslim actions for more than a decade. Outnumbered by their enemies, the Franks remained in a vulnerable position, but they could forge temporary alliances with their Armenian, Arab, and Turkic neighbours. Each Crusader state had its own strategic purpose during the first years of its existence. Jerusalem needed undisturbed access to the Mediterranean; Antioch wanted to seize Cilicia and the territory along the upper course of the
Orontes River; and Edessa aspired to control the Upper Euphrates valley. The most powerful Syrian Muslim ruler,
Toghtekin of Damascus, took a practical approach to dealing with the Franks. His treaties establishing Damascene–Jerusalemite
condominiums (shared rule) in debated territories created precedents for other Muslim leaders. In August 1099, Godfrey defeated the Fatimid Vizier
Al-Afdal Shahanshah at the
Battle of Ascalon. When
Daimbert of Pisa, the papal legate, arrived in the Levant with 120 ships, Godfrey gained much-needed naval support by backing him for the
Patriarchate of Jerusalem, as well as granting him parts of Jerusalem and the Pisans a section of the port of
Jaffa. Daimbert revived the idea of creating an ecclesiastic principality and extracted oaths of fealty from Godfrey and Bohemond. When Godfrey died in 1100, his retainers occupied the
Tower of David to secure his inheritance for his brother Baldwin. Daimbert and Tancred sought Bohemond's help against the Lotharingians, but the Danishmends captured Bohemond under
Gazi Gümüshtigin while securing Antioch's northern marches. Before departing for Jerusalem, Baldwin ceded Edessa to his cousin,
Baldwin of Bourcq. His arrival thwarted Daimbert, who crowned Baldwin as Jerusalem's first Latin king on Christmas Day 1100. By performing the ceremony, the patriarch abandoned his claim to rule the Holy Land. Tancred remained defiant to Baldwin until an Antiochene delegation offered him the regency in March 1101. He ceded his
Principality of Galilee to the king but reserved the right to reclaim it as a fief if he returned from Antioch within 15 months. For the next two years, Tancred ruled Antioch. He conquered Byzantine Cilicia and parts of Syria. The Fatimid Caliphate attacked Jerusalem in
1101,
1102 and
1105, on the last occasion in alliance with Toghtekin. BaldwinI repulsed these attacks and with Genoese, Venetian, and Norwegian fleets conquered all the towns on the Palestinian coast except Tyre and
Ascalon. Raymond laid the foundations of the fourth Crusader state, the County of Tripoli. He captured
Tartus and
Gibelet and
besieged Tripoli. His cousin
William II Jordan continued the siege after Raymond's death in 1105. It was completed in 1109 when Raymond's son
Bertrand arrived. Baldwin brokered a deal, sharing the territory between them, until William Jordan's death united the county. Bertrand acknowledged Baldwin's suzerainty, although William Jordan had been Tancred's vassal. When Bohemond was released for a ransom in 1103, he compensated Tancred with lands and gifts. Baldwin of Bourcq and his cousin and vassal,
Joscelin of Courtenay, were captured while attacking Ridwan of Aleppo at
Harran with Bohemond. Tancred assumed the regency of Edessa. The Byzantines took the opportunity to reconquer Cilicia. They took the port but not the citadel of
Laodikeia. Bohemond returned to Italy to recruit allies and gather supplies. Tancred assumed leadership in Antioch, and his cousin
Richard of Salerno did the same in Edessa. In 1107, Bohemond crossed the Adriatic Sea and failed in besieging
Dyrrachion in the
Balkan Peninsula. The resulting
Treaty of Devol forced Bohemond to restore Laodikeia and Cilicia to Alexios, become his vassal and reinstate the
Greek patriarch of Antioch. Bohemond never returned. He died, leaving an underage son
Bohemond II. Tancred continued as regent of Antioch and ignored the treaty. Richard's son,
Roger of Salerno, succeeded as regent on Tancred's death in 1112. The fall of Tripoli prompted Sultan Muhammad Tapar to appoint the of Mosul,
Mawdud, to wage jihad against the Franks. Between 1110 and 1113, Mawdud mounted four campaigns in Mesopotamia and Syria, but rivalry among his heterogeneous armies' commanders forced him to abandon the offensive on each occasion. As Edessa was Mosul's chief rival, Mawdud directed two campaigns against the city. They caused havoc, and the county's eastern region could never recover. The Syrian Muslim rulers saw the sultan's intervention as a threat to their autonomy and collaborated with the Franks. After an assassin, likely a Nizari, murdered Mawdud, Muhammad Tapar dispatched two armies to Syria, but both campaigns failed. As Aleppo remained vulnerable to Frankish attacks, the city leaders sought external protection. They allied with the adventurous Artuqid princes,
Ilghazi and
Balak, who inflicted crucial defeats on the Franks between 1119 and 1124 but could rarely prevent Frankish counter-invasions. In 1118 Baldwin of Bourcq succeeded BaldwinI as King of Jerusalem, naming Joscelin his successor in Edessa. After Roger was killed at ('Field of Blood'), BaldwinII assumed the regency of Antioch for the absent BohemondII. Public opinion attributed a series of disasters affecting the Outremer—defeats by enemy forces and plagues of locusts—as punishments for the Franks' sins. To improve moral standards, the Jerusalemite ecclesiastic and secular leaders assembled a
council at Nablus and issued decrees against adultery, sodomy, bigamy, and sexual relations between Catholics and Muslims. A proposal by a group of pious knights about a
monastic order for deeply religious warriors was likely first discussed at the council of Nablus. Church leaders quickly espoused the idea of armed monks, and within a decade, two
military orders, the
Knights Templar and
Hospitaller, were formed. As the Fatimid Caliphate no longer posed a major threat to Jerusalem, but Antioch and Edessa were vulnerable to invasion, the defence of the northern Crusader states took much of BaldwinII's time. His absence, its impact on government, and his placement of relatives and their vassals in positions of power created opposition in Jerusalem. Baldwin's sixteen-month captivity led to a failed deposition attempt by some of the nobility, with the
Flemish count Charles the Good considered as a possible replacement. Charles declined the offer. Baldwin had four daughters. In 1126, Bohemond reached the age of majority and married the second-oldest,
Alice, in Antioch. Aleppo had plunged into anarchy, but Bohemond II could not exploit this because of a conflict with Joscelin. The new of Mosul
Imad al-Din Zengi seized Aleppo in 1128. The two major Muslim centres' union was especially dangerous for the neighbouring Edessa, but it also worried Damascus's new ruler,
Taj al-Muluk Buri. Baldwin's eldest daughter
Melisende was his heir. He married her to
Fulk of Anjou, who had widespread western connections useful to the kingdom. After Fulk's arrival, Baldwin raised a large force for an attack on Damascus. This force included the leaders of the other Crusader states, and a significant
Angevin contingent was provided by Fulk. The campaign was abandoned when the Franks' foraging parties were destroyed, and bad weather made the roads impassable. In 1130 Bohemond II was killed raiding in Cilicia, leaving Alice with their infant daughter,
Constance. Baldwin II denied Alice control, instead resuming the regency until his death in 1131.
Muslim revival (1131 to 1174) On his deathbed Baldwin named Fulk, Melisende, and their infant son
BaldwinIII joint heirs. Fulk intended to revoke the arrangement, but his favouritism toward his compatriots roused strong discontent in the kingdom. In 1134, he repressed a revolt by
Hugh II of Jaffa, a relative of Melisende, but was still compelled to accept the shared inheritance. He also thwarted frequent attempts by his sister-in-law Alice to assume the regency in Antioch, including alliances with
Pons of Tripoli and
JoscelinII of Edessa. Taking advantage of Antioch's weakened position,
Leo, a
Cilician Armenian ruler, seized the Cilician plain. In 1133, the Antiochene nobility asked Fulk to propose a husband for Constance, and he selected
Raymond of Poitiers, a younger son of
William IX of Aquitaine. Raymond finally arrived in Antioch three years later and married Constance. He reconquered parts of Cilicia from the Armenians. In 1137, Pons was killed battling the Damascenes, and Zengi invaded Tripoli. Fulk intervened, but Zengi's troops captured Pons' successor
RaymondII, and besieged Fulk in the border castle of
Montferrand. Fulk surrendered the castle and paid Zengi 50,000dinars for his and Raymond's freedom. Emperor Alexios' son and successor,
John II Komnenos, reasserted Byzantine claims to Cilicia and Antioch. His military campaign compelled Raymond of Poitiers to give homage and agree that he would surrender Antioch by way of compensation if the Byzantines ever captured Aleppo,
Homs, and Shaizar for him. The following year the Byzantines and Franks jointly besieged Aleppo and Shaizar but could not take the towns. Zengi soon seized Homs from the Damascenes, but a Damascene–Jerusalemite coalition prevented his southward expansion. Joscelin made an alliance with the Artuqid
Kara Arslan, who was Zengi's principal Muslim rival in Upper Mesopotamia. While Joscelin was staying west of the Euphrates at Turbessel, Zengi invaded the Frankish lands east of the river in late 1144. Before the end of the year, he captured the region, including the city of Edessa. Losing Edessa strategically threatened Antioch and limited opportunities for a Jerusalemite expansion in the south. In September 1146, Zengi was assassinated, possibly on orders from Damascus. His empire was divided between his two sons, with the younger
Nur ad-Din succeeding him in Aleppo. A power vacuum in Edessa allowed Joscelin to return to the city, but he was unable to take the citadel. When Nur ad-Din arrived, the Franks were trapped, Joscelin fled and the subsequent sack left the city deserted. The fall of Edessa shocked Western opinion, prompting the largest military response since the First Crusade. The
new crusade consisted of two great armies led overland by
Louis VII of France and
Conrad III of Germany, arriving in
Acre in 1148. The arduous march had greatly reduced the two rulers' forces. At a leadership conference, including the widowed Melisende and her son BaldwinIII, they agreed to
attack Damascus rather than attempt to recover distant Edessa. The attack on Damascus ended in a humiliating defeat and retreat. Scapegoating followed the unexpected failure, with many westerners blaming the Franks. Fewer crusaders came from Europe to fight for the Holy Land in the next decades. Raymond of Poitiers joined forces with the Nizari and Joscelin with the Rum Seljuks against Aleppo. Nur ad-Din invaded Antioch and Raymond was
defeated and killed at
Inab in 1149. The next year Joscelin was captured and tortured and later died.
Beatrice of Saone, his wife, sold the remains of the County of Edessa to the Byzantines with Baldwin's consent. Already 21 and eager to rule alone, Baldwin forced Melisende's retirement in 1152. In Antioch, Constance resisted pressure to remarry until 1153 when she chose the French nobleman
Raynald of Châtillon as her second husband. In the 1150s, Manuel successfully asserted Byzantine suzerainty over Edessa and Antioch, and a series of Byzantine-Crusader marriage alliances sealed the dependence of the Crusader states on the Empire. However, Manuel's 1157-58 expedition would be the last time a full imperial army would campaign in Syria. From 1149, all Fatimid caliphs were children, and military commanders were competing for power. Ascalon, the Fatimids' last Palestinian bridgehead, hindered Frankish raids against Egypt, but Baldwin
captured the town in 1153. The Damascenes feared further Frankish expansion, and Nur ad-Din seized the city with ease a year later. He continued to remit the tribute that Damascus' former rulers had offered to the Jerusalemite kings. Baldwin extracted tribute from the Egyptians as well. Raynald lacked financial resources. He tortured the
Latin Patriarch of Antioch,
Aimery of Limoges, to appropriate his wealth and attacked the Byzantine's Cilician Armenians. When Emperor
Manuel I Komnenos delayed the payment he had been promised, Raynald pillaged
Byzantine Cyprus.
Thierry, Count of Flanders, brought military strength from the West for campaigning. Thierry, Baldwin, Raynald and
Raymond III of Tripoli attacked Shaizar. Baldwin offered the city to Thierry, who refused Raynald's demands he become his vassal, and the siege was abandoned. After Nur ad-Din seized Shaizar in 1157, the Nizari remained the last independent Muslim power in Syria. As prospects for a new crusade from the West were poor, the Franks of Jerusalem sought a marriage alliance with the Byzantines. Baldwin married Manuel's niece,
Theodora, and received a significant dowry. With his consent, Manuel forced Raynald into accepting Byzantine overlordship. The childless BaldwinIII died in 1163. His younger brother
Amalric had to repudiate his wife
Agnes of Courtenay on grounds of
consanguinity before his coronation, but the right of their two children,
Baldwin IV and
Sibylla, to inherit the kingdom was confirmed. The Fatimid Caliphate had rival viziers,
Shawar and
Dirgham, both eager to seek external support. This gave Amalric and Nur ad-Din the opportunity to intervene. Amalric launched five invasions of Egypt between 1163 and 1169, on the last occasion cooperating with a Byzantine fleet, but he could not establish a bridgehead. Nur ad-Din appointed his
Kurdish general
Shirkuh to direct the military operations in Egypt. Weeks before Shirkuh died in 1169, the Fatimid caliph
Al-Adid made him vizier. His nephew
Saladin, who ended the Shi'ite caliphate when Al-Adid died in September 1171, succeeded Shirkuh. In March 1171, Amalric undertook a visit to Manuel in Constantinople to get Byzantine military support for yet another attack on Egypt. To this end, he swore fealty to the Emperor before his return to Jerusalem, but conflicts
with Venice and Sicily prevented the Byzantines from campaigning in the Levant. In theory, Saladin was Nur ad-Din's lieutenant, but mutual distrust hindered their cooperation against the crusader states. As Saladin remitted suspiciously small revenue payments to him, Nur ad-Din began gathering troops for an attack on Egypt, but he died in May 1174. He left an 11-year-old son,
As-Salih Ismail al-Malik. Within two months, Amalric died. His son and successor, BaldwinIV, was 13 and a
leper.
Decline and survival (1174 to 1188) The accession of underage rulers led to disunity both in Jerusalem and in Muslim Syria. In Jerusalem, the
seneschal Miles of Plancy took control, but unknown assailants murdered him on the streets of Acre. With the baronage's consent, Amalric's cousin, RaymondIII of Tripoli, assumed the regency for BaldwinIV as . He became the most powerful baron by marrying
Eschiva of Bures, the richest heiress of the kingdom, and gaining Galilee. Nur ad-Din's empire quickly disintegrated. His
eunuch confidant
Gümüshtekin took As-Salih from Damascus to Aleppo. Gümüshtekin's rival,
Ibn al-Muqaddam, seized Damascus but soon surrendered it to Saladin. By 1176, Saladin reunited much of Muslim Syria through warring against Gümüshtekin and As-Salih's relatives, the
Zengids. That same year, Emperor Manuel invaded the Sultanate of Rum to reopen the Anatolian pilgrimage route towards the Holy Land. His defeat
at Myriokephalon weakened the Byzantines' hold on Cilicia. Upholding the balance of power in Syria was apparently Raymond's main concern during his regency. When Saladin besieged Aleppo in 1174, Raymond led a relief army to the city; next year, when a united Zengid army invaded Saladin's realm, he signed a truce with Saladin. Gümüshtekin released Raynald of Châtillon and Baldwin's maternal uncle,
Joscelin III of Courtenay, for a large ransom. They hastened to Jerusalem, and Raynald seized
Oultrejourdain by marrying
Stephanie of Milly. As Baldwin, a leper, was not expected to father children, his sister's marriage was to be arranged before his inevitable premature death from the disease. His regent, Raymond, chose
William of Montferrat for Sybilla's husband. William was the cousin of both
Holy Roman Emperor Frederick Barbarossa and LouisVII of France. In 1176, Baldwin reached the age of 15 and majority, ending Raymond's regency. He revisited plans for an invasion of Egypt and renewed his father's pact with the Byzantines. Manuel dispatched a fleet of 70 galleys plus support ships to Outremer. As William had died, and Baldwin's health was deteriorating, the Franks offered the regency and the Egyptian invasion's command to Baldwin's crusader cousin
Philip I, Count of Flanders. He wanted to be free to return to Flanders and rejected both offers. The plan for the invasion was abandoned, and the Byzantine fleet sailed for Constantinople. Baldwin negotiated a marriage between
Hugh III, Duke of Burgundy, and Sibylla, but the succession crisis in France prevented him from sailing. Tension between Baldwin's maternal and paternal relatives grew. When Raymond and Bohemond, both related to him on his father's side, came to Jerusalem unexpectedly before Easter in 1180, Baldwin panicked, fearing they had arrived to depose him and elevate Sibylla to the throne under their control. To thwart their coup, he sanctioned her marriage to
Guy of Lusignan, a young aristocrat from
Poitou. Guy's brother
Aimery held the office of
constable of Jerusalem, and
their family had close links to the
House of Plantagenet. Baldwin's mother and her clique marginalised Raymond, Bohemond and the influential
Ibelin family. To prepare for a military campaign against the Seljuks of Rum, Saladin concluded a two-year truce with Baldwin and, after launching a short but devastating campaign along the coast of Tripoli, with Raymond. For the first time in the history of Frankish–Muslim relations, the Franks could not set conditions for the peace. Between 1180 and 1183, Saladin asserted his suzerainty over the Artuqids, concluded a peace treaty with the Rum Seljuks, seized Aleppo from the Zengids and re-established the Egyptian navy. Meanwhile, after the truce expired in 1182, Saladin demonstrated the strategic advantage he had by holding both Cairo and Damascus. While he faced Baldwin in Oultrejordain, his troops from Syria pillaged Galilee. The Franks adopted a defensive tactic and strengthened their fortresses. In February 1183, a Jerusalemite assembly levied an extraordinary tax for defence funding. Raynald was the sole Frankish ruler to pursue an offensive policy. He attacked an Egyptian caravan and built a fleet for a naval raid into the
Red Sea. Byzantine influence declined after Manuel died in 1180. Bohemond repulsed his Byzantine wife
Theodora and married Sybil, an Antiochene noblewoman with a bad reputation. Patriarch Aimery excommunicated him and the Antiochene nobles who opposed the marriage fled to the Cilician Armenian prince,
RubenIII. Saladin granted a truce to Bohemond and made preparations for an invasion of Jerusalem where Guy took command of the defence. When Saladin invaded Galilee, the Franks responded with what
William of Tyre described in his contemporaneous
chronicle as their largest army in living memory but avoided fighting a battle. After days of fierce skirmishing, Saladin withdrew towards Damascus. Baldwin dismissed Guy from his position as , apparently because Guy had proved unable to overcome factionalism in the army. In November 1183, Baldwin made Guy's five-year-old stepson,
also called Baldwin, co-ruler, and had him crowned king while attempting to annul the marriage of Guy and Sibylla. Guy and Sibylla fled to Ascalon, and his supporters vainly intervened on their behalf at a general council. An embassy to Europe was met with offers of money but not of military support. Already dying, BaldwinIV appointed Raymond for 10years, but charged Joscelin with the ailing BaldwinV's guardianship. As there was no consensus on what should happen if the boy king died, it would be for the pope, the Holy Roman Emperor, the kings of France and England to decide whether his mother Sibylla or her half-sister
Isabella had stronger claim to the throne. Bohemond was staying at Acre around this time, allegedly because BaldwinIV wanted to secure Bohemond's support for his decisions on the succession. Back in Antioch, Bohemond kidnapped Ruben of Cilicia and forced him into becoming his vassal. 's chronicle Saladin signed a four-year truce with Jerusalem and attacked Mosul. He could not capture the city but extracted an oath of fealty from Mosul's Zengid ruler,
Izz al-Din Mas'ud, in March 1186. A few months later, BaldwinV died, and a power struggle began in Jerusalem. Raymond summoned the barons to
Nablus to a general council. In his absence, Sybilla's supporters, led by Joscelin and Raynald, took full control of Jerusalem, Acre and Beirut. Patriarch
Heraclius of Jerusalem crowned her queen and appointed Guy her co-ruler. The barons assembling at Nablus offered the crown to Isabella's husband
Humphrey IV of Toron, but he submitted to Sybilla to avoid a civil war. After his desertion, all the barons but
Baldwin of Ibelin and Raymond swore fealty to the royal couple. Baldwin went into exile, and Raymond forged an alliance with Saladin. Raynald seized another caravan, which violated the truce and prompted Saladin to assemble his forces for the jihād. Raymond allowed Muslim troops to pass through Galilee to raid around Acre. His shock at the Frankish defeat in the resulting
Battle of Cresson brought him to reconciliation with Guy. Guy now gathered a large force, committing all of his kingdom's available resources. The leadership divided on tactics. Raynald urged an offensive, while Raymond proposed defensive caution, although Saladin was besieging his castle at Tiberias. Guy decided to deal with the siege. The march towards Tiberias was arduous, and Saladin's troops overwhelmed the exhausted Frankish army
at the Horns of Hattin on 4July 1187. Hattin was a massive defeat for the Franks. Nearly all the major Frankish leaders were taken prisoner, but only Raynald and the armed monks of the military orders were executed. Raymond was among the few Frankish leaders who escaped captivity. He fell seriously ill after reaching Tripoli. Within months after Hattin, Saladin conquered almost the entire kingdom. The city of
Jerusalem surrendered on 2October 1187. There were no massacres following the conquest, but tens of thousands of Franks were enslaved. Those who could negotiate a free passage or were ransomed swarmed to Tyre, Tripoli, or Antioch.
Conrad of Montferrat commanded the
defences of Tyre. He was William's brother and arrived only days after Hattin. The childless Raymond died, and Bohemond's younger son, also called
Bohemond, assumed power in Tripoli. After news of the Franks' devastating defeat at Hattin reached Italy,
Pope Gregory VIII called for a
new crusade. Passionate sermons raised religious fervour, and it is likely that more people took the crusader oath than during recruitment for the previous crusades. Bad weather and growing discontent among his troops forced Saladin to abandon the siege of Tyre and allow his men to return to Iraq, Syria, and Egypt early in 1188. In May, Saladin turned his attention to Tripoli and Antioch. The arrival of
William II of Sicily's fleet saved Tripoli. Saladin released Guy on the condition that he go overseas and never bear arms against him. Historian Thomas Asbridge proposes that Saladin likely anticipated that a power struggle between Guy and Conrad was inevitable and it could weaken the Franks. Indeed, Guy failed to depart for Europe. In October, Bohemond asked Saladin for a seven-month truce, offering to surrender the city of Antioch if help did not arrive. Saladin's biographer
Ali ibn al-Athir wrote, after the Frankish castles were starved into submission, that "the Muslims acquired everything from as far as
Ayla to the furthest districts of Beirut with only the interruption of Tyre and also all the dependencies of Antioch, apart from
al-Qusayr".
Recovery and civil war (1189 to 1243) Guy of Lusignan, his brother Aimery, and
Gerard de Ridefort,
grand master of the Templars, gathered about 600 knights in Antioch. They approached Tyre, but Conrad of Montferrat refused them entry, convinced Guy had forfeited his claim to rule when Saladin conquered his kingdom. Guy and his comrades knew western crusaders would arrive soon and risked a token move
on Acre in August 1189. Crusader groups from many parts of Europe joined them. Their tactic surprised Saladin and prevented him from resuming the invasion of Antioch. Three major crusader armies departed for the Holy Land in 1189–1190. Frederick Barbarossa's crusade ended abruptly in June 1190 when he drowned in the
Saleph River in Anatolia. Only fragments of his army reached Outremer.
Philip II of France landed at Acre in April 1191, and
Richard I of England arrived in May. During his voyage, Richard had seized Cyprus from the island's self-declared emperor
Isaac Komnenos. Guy and Conrad had reconciled, but their conflict returned when Sybilla of Jerusalem and her two daughters by Guy died. Conrad married the reluctant Isabella, Sybilla's half-sister and heir, despite her marriage to Humphrey of Toron, and gossip about his two living wives. After an
attritional siege, the Muslim garrison surrendered Acre, and Philip and most of the French army returned to Europe. Richard led the crusade
to victory at
Arsuf, capturing Jaffa, Ascalon and
Darum. Internal dissension forced Richard to abandon Guy and accept Conrad's kingship. Guy was compensated with possession of Cyprus. In April 1192, Conrad was assassinated in Tyre. Within a week, the widowed Isabella was married to
Henry, Count of Champagne. Saladin did not risk a defeat in a pitched battle, and Richard feared the exhausting march across arid lands towards Jerusalem. As he fell ill and needed to return home to attend to his affairs, a three-year truce was agreed in September 1192. The Franks kept land between Tyre and Jaffa, but dismantled Ascalon; Christian pilgrimages to Jerusalem were allowed. Frankish confidence in the truce was not high. In April 1193,
Geoffroy de Donjon, head of the Knights Hospitaller, wrote in a letter, 'We know for certain that since the loss of the land the inheritance of Christ cannot easily be regained. The land held by the Christians during the truces remains virtually uninhabited.' The Franks' strategic position was not necessarily detrimental: they kept the coastal towns and their frontiers shortened. Their enclaves represented a minor threat to the Ayyubids' empire in comparison with the Artuqids, Zengids, Seljuks of Rum, Cilician Armenians or
Georgians in the north. After Saladin died in March 1193, none of his sons could assume authority over his
Ayyubid relatives, and the dynastic feud lasted for almost a decade. The Ayyubids agreed near-constant truces with the Franks and offered territorial concessions to keep the peace. BohemondIII of Antioch did not include his recalcitrant Cilician Armenian vassal
Leo in his truce with Saladin in 1192. Leo was RubenIII's brother. When Ruben died, Leo replaced his daughter and heir,
Alice. In 1191, Saladin abandoned a three-year occupation of the northern Syrian castle of
Bagras, and Leo seized it, ignoring claims of the Templars and Bohemond. In 1194, Bohemond accepted Leo's invitation to discuss Bagras' return, but Leo imprisoned him, demanding Antioch for his release. The Greek population and the Italian community rejected the Armenians, and formed a
commune under Bohemond's eldest son,
Raymond. Bohemond was released when he abandoned his claims on Cilicia, forfeiting Bagras and marrying Raymond to Alice. Any male heir of this marriage was expected to be the heir to both Antioch and Armenia. When Raymond died in 1197, Bohemond sent Alice and Raymond's posthumous son
Raymond-Roupen to Cilicia. Raymond's younger brother BohemondIV came to Antioch, and the commune recognised him as their father's heir. In September 1197, Henry of Champagne died after falling out a palace window in the kingdom's new capital Acre. The widowed Isabella married Aimery of Lusignan who had succeeded Guy in Cyprus. Saladin's ambitious brother
Al-Adil I, reunited Egypt and Damascus under his rule by 1200. He expanded the truces with the Franks and enhanced commercial contacts with Venice and Pisa. Bohemond III died in 1201. The
commune of Antioch renewed its allegiance to BohemondIV, although several nobles felt compelled to support Raymond-Roupen and joined him in Cilicia. Leo of Cilicia launched a series of military campaigns to assert Raymond-Roupen's claim to Antioch. Bohemond made alliances with Saladin's son,
Az-Zahir Ghazi of Aleppo, and with
SuleimanII, the Sultan of Rum. As neither Bohemond nor Leo could muster enough troops to defend their Tripolitan or Cilician hinterland against enemy invasions or rebellious aristocrats and to garrison Antioch simultaneously, the
War of the Antiochene Succession lasted for more than a decade. The Franks knew they could not regain the Holy Land without conquering Egypt. The leaders of the
Fourth Crusade planned an invasion of Egypt but
sacked Constantinople instead. Aimery and Isabella died in 1205. Isabella's daughter by Conrad,
Maria of Montferrat, succeeded, and Isabella's half-brother,
John of Ibelin, became regent. The regency ended with Maria's marriage in 1210 to
John of Brienne, a French aristocrat and experienced soldier. After her death two years later, John ruled as regent for their infant daughter,
IsabellaII. He participated in a military campaign against Cilicia, but it did not damage Leo's power. Leo and Raymond-Roupen had exhausted Antioch with destructive raids and occupied the city in 1216. Raymond-Roupen was installed as prince and Leo restored Bagras to the Templars. Raymond-Roupen could not pay for the aristocrats' loyalty in his impoverished principality and Bohemond regained Antioch with local support in 1219. The personal union between Antioch and Tripoli proved lasting, but in fact both crusader states disintegrated into small city-states. Raymond-Roupen fled to Cilicia, seeking Leo's support, and when Leo died in May, attempted to gain the throne against Leo's infant daughter
Isabella. John of Brienne was leader of a
gathering crusade but
FrederickII, the ruler of Germany and Sicily, was expected to assume control on his arrival; the papal legate,
Cardinal Pelagius, controlled the finances from the west. The crusaders invaded Egypt and
captured Damietta in November 1219. The new sultan of Egypt
Al-Kamil repeatedly offered the return of Jerusalem and the Holy Land in exchange for the crusaders' withdrawal. His ability to implement his truce proposals was questionable for his brother
Al-Mu'azzam Isa ruled the Holy Land. The crusaders knew that their hold on the territory would not be secure as long as the castles in Oultrejourdain remained in Muslim hands. Prophecies about their inevitable victory spread in their camp, and Al-Adil's offer was rejected. After twenty-one months of stalemate, the crusaders marched on Cairo before being trapped between the
Nile floods and the Egyptian army. The crusaders surrendered Damietta in return for safe conduct, ending the crusade. While staying in Damietta, Cardinal Pelagius sent reinforcements to Raymond-Roupen in Cilicia, but
Constantine of Baberon, who was regent for the Cilician queen, acted quickly. He captured Raymond-Roupen, who died in prison. The queen was married to Bohemond's son,
Philip to cement an alliance between Cilicia and Antioch. A feud between the two nations broke out again after neglected Armenian aristocrats murdered Philip in late 1224. An alliance between the Armenians and his former Ayyubid allies in Aleppo foiled Bohemond's attempts at revenge. Frederick renewed his crusader oath on his
imperial coronation in Rome in 1220. He did not join the Egyptian crusade but reopened the negotiations with Al-Adil over the city of Jerusalem. In 1225, Frederick married IsabellaII and assumed the title of king of Jerusalem. Two years later, Al-Adil promised to abandon all lands conquered by Saladin in return for Frankish support against Al-Mu'azzam. An epidemic prevented Frederick's departure for a crusade, and
Pope Gregory IX excommunicated him for repeatedly breaking his oath. In April 1228, Isabella died after giving birth to
Conrad. Without seeking a reconciliation with the Pope, Frederick sailed
for the crusade. His attempts to confiscate baronial fiefs brought him into conflict with the Frankish aristocrats. As Al-Mua'zzam had died, Frederick made the most of his diplomatic skills to achieve the partial implementation of Al-Adil's previous promise. They signed a
truce for ten years, ten months, and ten days (the maximum period for a peace treaty between Muslims and Christians, according to Muslim custom). It restored Jerusalem, Bethlehem,
Nazareth and
Sidon to the Franks while granting
Temple Mount to the Muslims. The native Franks were unenthusiastic about the treaty because it was questionable whether it could be defended. Frederick left for Italy in May 1229, and never returned. He sent
Richard Filangieri, with an army, to rule the kingdom of Jerusalem as his . The Ibelins denied Frederick's right to appoint his lieutenant without consulting the barons, and Outremer plunged into a civil war, known as the
War of the Lombards. Filangieri occupied Beirut and Tyre, but the Ibelins and their allies firmly kept Acre and established a commune to protect their interest. Pope Gregory IX called for a
new crusade in preparation for the expiry of the truce. Between 1239 and 1241, wealthy French and English nobles like
Theobald I of Navarre and
Richard of Cornwall led separate military campaigns to the Holy Land. They followed Frederick's tactics of forceful diplomacy and played rival factions off against each other in the succession disputes that followed Al-Kamil's death. Richard's treaty with Al-Kamil's son,
As-Salih Ayyub, restored most land west of the Jordan River to the Franks. Conrad reached the age of majority in 1243 but failed to visit Outremer. Arguing that Conrad's
heir presumptive was entitled to rule in his absence, the Jerusalemite barons elected his mother's maternal aunt,
Alice of Champagne, as regent. The same year, they captured Tyre, the last centre of Frederick's authority in the kingdom.
Destruction by the Mamluks (1244 to 1291) The
Mongol Empire's westward expansion reached the Middle East when the
Mongols conquered the
Khwarazmian Empire in Central Asia in 1227. Part of the Khwarazmian army fled to eastern Anatolia and these masterless Turkic soldiers offered their services to the neighbouring rulers for pay. Western Christians regarded the Mongols as potential allies against the Muslims because some Mongol tribes adhered to
Nestorian Christianity. In fact, most Mongols were pagans with a strong belief in their
Great Khan's divine right to universal rule, and they demanded unconditional submission from both Christians and Muslims. As-Salih Ayyub hired the Khwarazmians and garrisoned new troops in Egypt, alarming his uncle
As-Salih Ismail, Emir of Damascus. Ismail bought the Franks' alliance by a promise to restore 'all the lands that Saladin had reconquered'. Catholic priests took possession of the Dome of the Rock, but in July 1244 Khwarazmians marching towards Egypt
sacked Jerusalem unexpectedly. The Franks gathered all available troops and joined Ismail near Gaza, but the Khwarazmians and Egyptians defeated the Frankish and Damascene coalition
at La Forbie on 18 October. Few Franks escaped from the battlefield. As-Salah captured most of the crusaders' mainland territory, restricting the Franks to a few coastal towns.
Louis IX of France launched a
failed crusade against Egypt in 1249. He was
captured near Damietta with the remnants of his army, and ransomed days after the
Bahri Mamluks assumed power in Egypt through murdering As-Salih's son
Al-Muazzam Turanshah in May 1250. Louis spent four more years in Outremer. As the kingdom's effective ruler, he conducted negotiations with both the Syrian Ayyubids and the Egyptian Mamluks and refortified the coastal towns. He sent an embassy from Acre to the Great Khan
Güyük, offering an anti-Muslim alliance to the Mongols. Feuds between rival candidates to the regency and commercial conflicts between Venice and Genoa resulted in a new civil war in 1256 known as the
War of Saint Sabas. The pro-Venetian
Bohemond VI's conflict with his Genoese vassals the
Embriaci brought the war to Tripoli and Antioch. In 1258, the
Hulagu, younger brother of the Great Khan
Möngke,
sacked Baghdad and ended the Abbasid Caliphate. Two years later,
Hethum I of Cilicia and Bohemond VI joined forces with the Mongols in the
sack of Aleppo, when Bohemond set fire to
its mosque, and in the conquest of northern Syria. The Mongols emancipated the Christians from their status, and the local Christian population cooperated with the conquerors. Jerusalem remained neutral when the Mamluks of Egypt moved to confront the Mongols after Hulagu, and much of his force moved east on the death of Möngke to address the Mongol succession. The Mamluks defeated the greatly reduced Mongol army
at Ain Jalut. On their return, the Mamluk sultan
Qutuz was assassinated and replaced by the general
Baibars. Baibars revived Saladin's empire by uniting Egypt and Syria and held Hulagu in check through an alliance with the Mongols of the
Golden Horde. He reformed governance in Egypt, giving power to the elite . The Franks did not have the military capability to resist this new threat. A Mongol garrison was stationed at Antioch, and individual Frankish barons concluded separate truces with Baibars. Determined to conquer the crusader states, he captured
Caesarea and Arsuf in 1265 and
Safed in 1266, and
sacked Antioch in 1268. Jaffa surrendered and Baibers weakened the military orders by capturing the castles of
Krak des Chevaliers and
Montfort before returning his attention to the Mongols of the
Ilkhanate for the rest of his life. Massacres of the Franks and native Christians regularly followed a Mamluk conquest. In 1268, the new Sicilian king
Charles I of Anjou executed
Conradin, the titular king of Jerusalem, in Naples after his victory
at Tagliacozzo. Isabella I's great-grandson
Hugh III of Cyprus and her granddaughter
Maria of Antioch disputed the succession. The barons preferred Hugh, but in 1277 Maria sold her claim to Charles. He sent
Roger of San Severino to act as . With the support of the Templars, he blocked Hugh's access to Acre, forcing him to retreat to Cyprus, again leaving the kingdom without a resident monarch. The Mongols of the Ilkhanate sent embassies to Europe proposing anti-Mamluk alliances, but the major western rulers were reluctant to launch a new crusade for the Holy Land. The
War of the Sicilian Vespers weakened Charles's position in the west. After his death in 1285,
Henry II of Cyprus was acknowledged as Jerusalem's nominal king, but the rump kingdom was in fact a mosaic of autonomous lordships, some under Mamluk suzerainty. In 1285, the death of the warlike
Abaqa, combined with the Pisan and Venetian wars with the Genoese, finally gave the Mamluk sultan,
Al-Mansur Qalawun, the opportunity to expel the Franks. In 1289 he
destroyed Genoese-held Tripoli, enslaving or killing its residents. In 1290, Italian crusaders broke his truce with Jerusalem by killing Muslim traders in Acre. Qalawun's death did not hinder the successful Mamluk
siege of the city in 1291. Those who could fled to Cyprus, while those who could not were slaughtered or sold into slavery. Without hope of support from the West, Tyre, Beirut, and Sidon all surrendered without a fight. The Mamluk policy was to destroy all physical evidence of the Franks; the destruction of the ports and fortified towns ruptured the history of a
coastal city civilisation rooted in antiquity. ==Government and institutions==
