The Battle of Qinnasrin took place between the Zengids and the County of Tripoli following a successful campaign against Antioch led by Imad al-Din Zengi.
[1] In 1135 Imad al-Din Zengi led a campaign against Antioch during which he captured Atharib, Zardana, Tell Aghdi, Ma’arat al-Nu’man, Ma’arrat Misrin and Kafartab.
[2][3] The Count of Tripoli, Pons, in an attempt to make up for the loss of Ma’arat al-Nu’man and block the road that crossed Syria from north to south, launched an attack on Qinnasrin, however Zengi repelled the attack and the Franks retreated.
