Raymond of Poitiers is defeated and killed at the Battle of Inab by Nur ad-Din Zangi.

Raymond of Poitiers was Prince of Antioch from 1136 to 1149. He was the younger son of William IX, Duke of Aquitaine, and his wife Philippa, Countess of Toulouse, born in the very year that his father the Duke began his infamous liaison with Dangereuse de Chatelherault.

The Battle of Inab, also called Battle of Ard al-Hâtim or Fons Muratus, was fought on 29 June 1149, during the Second Crusade. The Zengid army of the atabeg Nur al-Din Zengi destroyed the combined army of Prince Raymond of Antioch and the Assassins of Ali ibn-Wafa. The prince was killed, and the Principality of Antioch was subsequently pillaged and reduced in size as its eastern border was pushed west.
