Salah ad-Din Yusuf ibn Ayyub, commonly known as Saladin, was the founder of the Ayyubid dynasty. Hailing from a Kurdish family, he was the first sultan of both Egypt and Syria. An important figure of the Third Crusade, he spearheaded the Muslim military effort against the Crusader states in the Levant. At the height of his power, the Ayyubid realm spanned Egypt, Syria, Upper Mesopotamia, the Hejaz, Yemen, and Nubia.
Year 1137 (MCXXXVII) was a common year starting on Friday of the Julian calendar.
The County of Tripoli (1102–1289) was one of the Crusader states. It was founded in the Levant in the modern-day region of Tripoli, northern Lebanon and parts of western Syria. When the Frankish Crusaders, mostly southern French forces – captured the region in 1109, Bertrand of Toulouse became the first count of Tripoli as a vassal of King Baldwin I of Jerusalem. From that time on, the rule of the county was decided not strictly by inheritance but by factors such as military force, favour and negotiation. In 1289, the County of Tripoli fell to the Muslim Mamluks of Cairo under Sultan Qalawun, and the county was absorbed into Mamluk Sultanate.
Raymond III was count of Tripoli from 1152 to 1187. He was a minor when Nizari Assassins murdered his father, Raymond II of Tripoli. Baldwin III of Jerusalem, who was staying in Tripoli, made Raymond's mother, Hodierna of Jerusalem, regent. Raymond spent the following years at the royal court in Jerusalem. He reached the age of majority in 1155, after which he participated in a series of military campaigns against Nur ad-Din, the Zengid ruler of Damascus. In 1161 he hired pirates to pillage the Byzantine coastline and islands to take vengeance on Byzantine emperor Manuel I Komnenos, who had refused to marry his sister Melisende. He was captured in the Battle of Harim by Nur ad-Din's troops on 10 August 1164, and imprisoned in Aleppo for almost ten years. During his captivity, Amalric I of Jerusalem administered the county of Tripoli on his behalf.
Raymond II was count of Tripoli from 1137 to 1152. He succeeded his father, Pons, Count of Tripoli, who was killed during a campaign that a commander from Damascus launched against Tripoli. Raymond accused the local Christians of betraying his father and invaded their villages in the Mount Lebanon area. He also had many of them tortured and executed. Raymond was captured during an invasion by Imad ad-Din Zengi, atabeg of Mosul, who gained the two important castles of Montferrand and Rafaniya in exchange for his release in the summer of 1137.
Pons was count of Tripoli from 1112 to 1137. He was a minor when his father, Bertrand, died in 1112. He swore fealty to the Byzantine Emperor Alexios I Komnenos in the presence of a Byzantine embassy. His advisors sent him to Antioch to be educated in the court of Tancred of Antioch, ending the hostilities between the two crusader states. Tancred granted four important fortresses to Pons in the Principality of Antioch. Since Pons held his inherited lands in fief of the kings of Jerusalem, Tancred's grant strengthened the autonomy of the County of Tripoli. On his deathbed, Tancred also arranged the marriage of his wife, Cecile of France, to Pons.
The Battle of Azaz was a major battle fought between king Baldwin II's crusader forces and the Muslims, led by Aq-Sunqur al-Bursuqi, the Seljuq atabeg of Mosul on 11 June 1125. Being one of the bloodiest confrontations before the Second Crusade, the battle resulted in a decisive victory for the Crusaders, causing disturbances of power in the Levant and weakened Seljuk domination in the area. Contemporary chronicler Matthew of Edessa even states that the remnants of al-Bursuqi's army were chased all the way to Aleppo. The battle effectively lifted the siege of the town of Azaz and prevented it from falling to Turkoman hands.
The Battle of Montgisard was fought between the Kingdom of Jerusalem and the Ayyubid Dynasty on 25 November 1177 at Montgisard, in the Levant between Ramla and Yibna. The 16-year-old Baldwin IV of Jerusalem, severely afflicted by leprosy, led outnumbered Christian forces against Saladin's troops in what became one of the most notable engagements of the Crusades. The Muslim Army was quickly routed and pursued for twelve miles. Saladin fled back to Cairo, reaching the city on 8 December, with only a tenth of his army. Muslim historians considered Saladin's defeat to be so severe that it was only redeemed by his victory ten years later at the battles of Cresson and Hattin and the Siege of Jerusalem in 1187. Saladin did defeat Baldwin IV in the Battle of Marj Ayyun and the Siege of Jacob’s Ford in 1179, only to be defeated by Baldwin again at the Battle of Belvoir Castle in 1182 and the Siege of Kerak in 1183.
The Battle of Cresson was a small battle between Frankish and Ayyubid forces on 1 May 1187 at the "Spring of the Cresson." While the exact location of the spring is unknown, it is located in the environs of Nazareth. The conflict was a prelude to decisive defeat of the Kingdom of Jerusalem at the Battle of Hattin two months later.
The Crusades were a series of religious wars initiated, supported, and sometimes directed by the Christian Latin Church in the medieval period. The best known of these military expeditions are those to the Holy Land in the period between 1095 and 1291 that had the objective of reconquering Jerusalem and its surrounding area from Muslim rule after the region had been conquered by the Rashidun Caliphate centuries earlier. Beginning with the First Crusade, which resulted in the conquest of Jerusalem in 1099, dozens of military campaigns were organised, providing a focal point of European history for centuries. Crusading declined rapidly after the 15th century.
Cecile of France was a French princess, daughter of Philip I of France and Bertrade de Montfort.
The Battle of Hab, also known as the Second Battle of Tell Danith, occurred on August 14, 1119, where a Crusader army commanded by King Baldwin II of Jerusalem won a disputed victory over a Muslim army led by Ilghazi of Mardin since the Muslim army claimed it as a victory also. The battle stabilized the Principality of Antioch, which had suffered a disastrous defeat only weeks before. Baldwin II managed to re-take all of the castles conquered by Ilghazi and prevented him from marching on Antioch.
The Battle of Belvoir Castle, also called the Battle of Le Forbelet, was a part of Saladin’s campaign in May — August 1182 against the Crusaders. Crusader forces led by King Baldwin IV of Jerusalem battled with Ayyubid forces from Egypt commanded by Saladin. Saladin took action in Damascus on June 11, 1182, together with his regent Farrukh Shah. Entering Palestine from the south of Tiberias, Saladin encountered the Crusader army coming from Transoxiana near Belvoir Castle. In the following battle, both sides attacked each other, and this fight, whose outcome was uncertain, ended in the evening.
The military history of the Crusader states begins with the formation of the County of Edessa in 1097 and ends with the loss of Ruad in 1302, the last Christian stronghold in the Holy Land.
In the Battle of Lake Huleh in June 1157, a Crusader army led by King Baldwin III of Jerusalem was ambushed and badly defeated by Nur ad-Din Zangi, the emir of Aleppo and Damascus. While the king and some fighting men escaped to a nearby castle, a large number were killed or made prisoner. The Latin Kingdom of Jerusalem escaped worse damage when their adversary became ill and was unable to follow up his victory. The Hula Valley is located in the northeast part of modern-day Israel. At the time of the battle, the area belonged to the Kingdom of Jerusalem.

Gibelacar, also known by its original Arabic name Hisn Ibn Akkar or its modern Arabic name Qal'at Akkar, is a fortress in the village of Akkar al-Atiqa in the Akkar Governorate in northern Lebanon. The fortress dates back to the Fatimid era in the early 11th century. It was captured and utilized by the Crusaders in the early 12th century until it was captured and strengthened by the Mamluks in the late 13th century. It became the headquarters of the Sayfa clan, whose members, chief among them Yusuf Pasha, served as the governors and tax farmers of the Tripoli Eyalet and its sanjaks from 1579 through the mid-17th century.
The Khwarazmian army, also called the Khwarazmiyya, maintained itself as a force of freebooters and mercenaries between 1231 and 1246, following the Mongol conquest of the Khwarazmian Empire (1221) and the death of the last Khwarazmshah, Jalal al-Din (1231). It was active in Upper Mesopotamia, Anatolia, Syria and Palestine and shifted its allegiance several times, often acting autonomously before it was defeated and destroyed by the Ayyubids.
