King of Jerusalem

In 1127 Fulk V, Count of Anjou, received an embassy from King Baldwin II of Jerusalem. Baldwin II had no male heirs but had already designated his daughter Melisende to succeed him. Baldwin II wanted to safeguard his daughter's inheritance by marrying her to a powerful lord. Fulk was a wealthy crusader and experienced military commander, and a widower. His experience in the field would prove invaluable in a frontier state always in the grip of war.

However, Fulk held out for better terms than mere consort of the Queen; he wanted to be king alongside Melisende. Baldwin II, reflecting on Fulk's fortune and military exploits, acquiesced. Fulk then resigned his titles to his son Geoffrey and sailed to become King of Jerusalem, where he married Melisende on 2 June 1129. Later Baldwin II bolstered Melisende's position in the kingdom by making her sole guardian of her son by Fulk, Baldwin III, born in 1130.

Fulk and Melisende became joint rulers of Jerusalem in 1131 with Baldwin II's death. From the start Fulk assumed sole control of the government, excluding Melisende altogether. He favored fellow countrymen from Anjou to the native nobility. The other crusader states to the north feared that Fulk would attempt to impose the suzerainty of Jerusalem over them, as Baldwin II had done; but as Fulk was far less powerful than his deceased father-in-law, the northern states rejected his authority.

The death of Fulk, as depicted in MS of William of Tyre's Historia and Old French Continuation, painted in Acre, 13C. Bib. Nat. Française.

In Jerusalem as well, Fulk was resented by the second generation of Jerusalem Christians who had grown up there since the First Crusade. These "natives" focused on Melisende's cousin, the popular Hugh II of Le Puiset, count of Jaffa, who was devotedly loyal to the Queen. Fulk saw Hugh as a rival, and in 1134, in order to expose Hugh, accused him of infidelity with Melisende. Hugh rebelled in protest and secured himself to Jaffa, allying himself with the Muslims of Ascalon. He was able to defeat the army set against him by Fulk, but this situation could not hold. The Patriarch interceded in the conflict, perhaps at the behest of Melisende. Fulk agreed to peace and Hugh was exiled from the kingdom for three years, a lenient sentence.

However, an assassination attempt was made against Hugh. Fulk, or his supporters, were commonly believed responsible, though direct proof never surfaced. The scandal was all that was needed for the queen's party to take over the government in what amounted to a palace coup. Author and historian Bernard Hamilton wrote that the Fulk's supporters "went in terror of their lives" in the palace. Contemporary author and historian William of Tyre wrote of Fulk "he never attempted to take the initiative, even in trivial matters, without (Melisende's) consent". The result was that Melisende held direct and unquestioned control over the government from 1136 onwards. Sometime before 1136 Fulk reconciled with his wife, and a second son, Amalric, was born.

In 1143, while the king and queen were on holiday in Acre, Fulk was killed in a hunting accident. His horse stumbled, fell, and Fulk's skull was crushed by the saddle, "and his brains gushed forth from both ears and nostrils", as William of Tyre describes. He was carried back to Acre, where he lay unconscious for three days before he died. He was buried in the Church of the Holy Sepulchre in Jerusalem. Though their marriage started in conflict, Melisende mourned for him privately as well as publicly. Fulk was survived by his son Geoffrey Plantagenet, Count of Anjou by his first wife, and Baldwin III and Amalric I by Melisende.

Baldwin III ascended the throne with his mother as co-ruler, in 1143. His early reign was laced with squabbles with his mother over the possession of Jerusalem, till 1153, when he took personal hold of the government. He died in 1163, without heirs, and the kingdom passed to his brother, Amalric I, although there was some opposition among the nobility to Amalric's wife Agnes; they were willing to accept the marriage in 1157 when Baldwin III was still capable of siring an heir, but now the Haute Cour refused to endorse Amalric as king unless his marriage to Agnes was annulled. The hostility to Agnes, it must be admitted, may be exaggerated by the chronicler William of Tyre, whom she prevented from becoming Latin Patriarch of Jerusalem decades later, as well as from William's continuators like Ernoul, who hints at a slight on her moral character: "car telle n'est que roine doie iestre di si haute cite comme de Jherusalem" ("there should not be such a queen for so holy a city as Jerusalem").

Nevertheless, consanguinity was enough for the opposition. Amalric agreed and ascended the throne without a wife, although Agnes continued to hold the title Countess of Jaffa and Ascalon and received a pension from that fief's income. The church ruled that Agnes's children were legitimate and preserved their place in the order of succession. Through them Agnes would exert much influence in Jerusalem for almost 20 years. Almaric was succeeded by his son by Agnes, Baldwin IV.

The marriage of Amalric I of Jerusalem and Maria Comnena at Tyre

Almaric's first wife Agnes of Courtenay was now married to Reginald of Sidon;Maria Comnena, the dowager Queen, had married Balian of Ibelin in 1177. His daughter by Agnes, Sibylla, was already of age, the mother of a son, and was clearly in a strong position to succeed her brother, but Maria's daughter Isabella had the support of her stepfather's family, the Ibelins.

In 1179, Baldwin began planning to marry Sibylla to Hugh III of Burgundy, but by spring 1180 this was still unresolved. Raymond III of Tripoli attempted a coup, and began to march on Jerusalem with Bohemund III, to force the king to marry his sister to a local candidate of his own choosing, probably Baldwin of Ibelin, Balian's older brother. To counter this, the king hastily arranged her marriage to Guy of Lusignan, younger brother of Amalric, the constable of the kingdom. A foreign match was essential to bring the possibility of external military aid to the kingdom. With the new French king Philip II a minor, Guy's status as a vassal of the King and Sibylla's first cousin Henry II of England – who owed the Pope a penitential pilgrimage – was useful.

By 1182, Baldwin IV, increasingly incapacitated by his leprosy, named Guy as bailli. Raymond contested this, but when Guy fell out of favour with Baldwin the following year, he was re-appointed bailli and was given possession of Beirut. Baldwin came to an agreement with Raymond and the Haute Cour to make Baldwin of Montferrat, Sibylla's son by her first marriage, his heir, before Sibylla and Guy. The child was crowned co-king as Baldwin V in 1183 in a ceremony presided by Raymond. It was agreed that, should the boy die during his minority, the regency would pass to "the most rightful heirs" until his kinsmen – the Kings of England and France and Frederick I, Holy Roman Emperor – and the Pope were able to adjudicate between the claims of Sibylla and Isabella. These "most rightful heirs" were not named.

Baldwin IV died in spring 1185, and was succeeded by his nephew. Raymond was bailli, but he had passed Baldwin V's personal guardianship to Joscelin III of Edessa, his maternal great-uncle, claiming that he did not wish to attract suspicion if the child, who does not seem to have been robust, were to die. Baldwin V died during the summer of 1186, at Acre. Neither side paid any heed to Baldwin IV's will.

After the funeral, Joscelin had Sibylla named as her brother's successor, although she had to agree to divorce Guy, just as her father had divorced her mother, with the guarantee that she would be allowed to choose a new consort. Once crowned, she immediately crowned Guy. Meanwhile, Raymond had gone to Nablus, home of Balian and Maria, and summoned all those nobles loyal to Princess Isabella and the Ibelins. Raymond wanted instead to have her and her husband Humphrey IV of Toron crowned. However, Humphrey, whose stepfather Raynald of Châtillon was an ally of Guy, deserted him and swore allegiance to Guy and Sibylla.

Just 13 year old when he ascended to the throne, he immediately had to deal with the loss of Edessa in 1144 and the Second Crusade through 1149. He engaged his mother in a civil war from 1152 to 1154, with the two eventually reconciling.[6] He was responsible for the military first success after the Second Crusade, the siege of Ascalon of 1153, resulting in the capture of a strategic fortress from the Fatimids. In 1156, Baldwin was forced into a treaty with Nūr-ad-Din, and later entered into an alliance with the Byzantine Empire. Melisende died on 11 September 1161, and Baldwin succumbed two years later on 10 February 1163. Childless, he was succeeded by his brother, Amalric.

He married Agnes of Courtenay and, after an annulment, Maria Komnene. Three of Amalric's children would assume the throne of Jerusalem. He undertook a series of four invasions of Egypt from 1163 to 1169, taking advantage of weaknesses of the Fatimids. The campaign was generally indecisive, but did lay the groundwork for the takeover of Egypt by Saladin in 1171. Amalric died at a young age, on 11 July 1174, and was succeeded by his son Baldwin IV of Jerusalem.
Baldwin IV the Leprous 1174–1185 with Baldwin V from 1183		1161 Jerusalem son of King Amalric and Agnes of Courtenay	never married	16 March 1185 Jerusalem aged 24 [8]	Became king on 5 July 1174 at the age of 13. As a leper he was not expected to live long, and served with a number of regents, and served as co-ruler with his cousin Baldwin V of Jerusalem beginning in 1183. Baldwin IV's rule began simultaneously with the death of Nūr-ad-Din and the rise of Saladin. Notably, Baldwin and Raynald of Châtillon defeated Saladin at the celebrated battle of Montgisard on 25 November 1177, and repelled his attacks at the battle of Belvoir Castle in 1182 and later in the siege of Kerak of 1183.[9] He died on 16 March 1185.
Baldwin V 1183–1186 with Baldwin IV until 1185[10]		1177 son of William of Montferrat and Sibylla of Jerusalem	never married	August 1186 Acre, Kingdom of Jerusalem aged 9	Became sole king upon the death of his uncle in 1185 under the regency of Raymond III of Tripoli.[11] Raymond negotiated a truce with Saladin which went awry when Baldwin V died in the summer of 1186.[12] He was succeeded in the kingdom by his mother Sibylla of Jerusalem—daughter of Amalric—and his stepfather, the French knight Guy of Lusignan.

They immediately had to deal with the threat posed by Saladin, and, in particular the battle of Hattin in 1187. During the battle Guy was captured, and remained in Saladin's custody until 1188. After the fall of Jerusalem, Sibylla fled to Tripoli, later joining Guy in Acre to meet the vanguard of the Third Crusade. She died on 25 July 1190.

After much political haranguing, she married Conrad of Montferrat on 24 November 1190, with him become de jure king. In April 1192, Conrad was elected king but on 28 April 1192, he was felled by two Assassins before he could be crowned. Richard was suspected as supported the murder, a suspicion that remains unproven.[13]

A former commander at the Battle of Hattin of 1187 as well as King of Cyprus since the death of Guy of Lusignan in 1194, his rule was a period of peace and stability in both of his realms. In particular, he signed a truce with al-Adil, now Ayyubid sultan of Egypt in 1198 which secured the Christian possession of the coastline from Acre to Antioch. This truce essentially prevented the remnants of the Fourth Crusade from their mission. He died on 1 April 1205. His son Hugh I of Cyprus succeeded him in Cyprus, while Isabella I continued to rule the Kingdom of Jerusalem. Isabella died four days later on 5 April 1205 and was succeeded by her daughter by Conrad, Maria of Montferrat, who served through 1212, with her husband John of Brienne after 1210.

The frequent absence or minority of monarchs required regents to be appointed many times throughout the Kingdom's existence.
