The siege of Baalbek in 1139 was undertaken by Imad al-Din Zengi who laid siege to the city in August and captured it in October.[1]
In 1139 Imad al-Din Zengi marched south of Aleppo to Baalbek which he laid siege to on 28 August with a large army and fourteen siege engines.[2][1] The town was captured on 9 or 10 October and the citadel surrendered on 12 or 21 October after Zengi swore to spare the lives of the garrison.[1][2] Zengi broke his oath and they were all brutally massacred, the governor was flayed and most of the others were hanged.[1][2] The massacre was intended to terrify the Damascenes.[2] Zengi named Nağm ad-Din Ayyub, the father of Saladin, as the governor of Baalbek.[3]
