Raynald of Châtillon, French knight (b. 1125)

Raynald of Châtillon (French: Renaud; c. 1125 – 4 July 1187), also known as Reynald or Reginald, was Prince of Antioch from 1153 to 1160 or 1161, and Lord of Oultrejordain from 1175 until his death. He was born the second son of a French noble family. After losing a part of his patrimony, he joined the Second Crusade in 1147. He settled in the Kingdom of Jerusalem and served in the royal army as a mercenary.

Raynald married Constance, the reigning Princess of Antioch, in 1153, in spite of her subjects' opposition. He was always in need of funds. He captured and tortured Aimery of Limoges, Latin Patriarch of Antioch, because Aimery had refused to pay a subsidy to him. Raynald launched a plundering raid in Cyprus in 1155, causing great destruction. Four years later, the Byzantine Emperor, Manuel I Komnenos, came to Antioch at the head of a large army, forcing Raynald to beg for his mercy. Raynald made a raid in the valley of the river Euphrates at Marash to seize booty from the local peasants in 1160 or 1161, but he was captured by the governor of Aleppo.

Raynald was held in prison until 1176. After his release for a large ransom, he did not return to Antioch, because his wife had meanwhile died. He married Stephanie of Milly, the wealthy heiress of Oultrejordain. Since Baldwin IV of Jerusalem also granted Hebron to him, Raynald was one of the wealthiest barons of the realm. He controlled the caravan routes between Egypt and Syria. Baldwin, who suffered from leprosy, made him regent in 1177. Raynald led the crusader army that defeated Saladin at the Battle of Montgisard. He was the only Christian leader to pursue an offensive policy against Saladin, making plundering raids against the caravans travelling near his domains. He built a fleet of five ships which plundered the coast of the Red Sea, threatening the route of the Muslim pilgrims towards Mecca in early 1183. Saladin pledged that he would never forgive Raynald.

Raynald was a firm supporter of Baldwin IV's sister, Sybilla, and her husband, Guy of Lusignan, during conflicts regarding the succession of the king. Sibylla and Guy were able to seize the throne in 1186 due to Raynald's co-operation with her uncle, Joscelin III of Courtenay. Raynald attacked a caravan travelling from Egypt to Syria in late 1186 or early 1187, claiming that the truce between Saladin and the Kingdom of Jerusalem did not bind him. After Raynald refused to pay a compensation, Saladin invaded the kingdom and annihilated the crusader army in the Battle of Hattin. Raynald was captured in the battlefield. Saladin personally beheaded him after he refused to convert to Islam. Most historians have regarded Raynald as an irresponsible adventurer whose lust for booty caused the fall of the Kingdom of Jerusalem. On the other hand, Bernard Hamilton says that he was the only crusader leader who tried to prevent Saladin from unifying the nearby Muslim states.
