BIOGRAPHICAL DOSSIER

Life and historical role

01

Life and political setting

John II became emperor in 1118 on the death of his father Alexios I Komnenos. He survived his sister Anna Komnene's attempt on the throne and campaigned successfully against the Pechenegs, the Hungarians and the Turks in Anatolia. Byzantine sources praise his character and piety.

02

Role in the Crusades

In 1137 he took Armenian Cilicia and besieged Antioch; Prince Raymond of Poitiers was forced to swear allegiance to the emperor. In 1138 Latin and Byzantine forces jointly besieged Shaizar, but the Latin leaders' reluctance left the siege inconclusive. The emperor entered Antioch in ceremony but left after unrest in the city.

03

Historical significance and source problems

While preparing a new Syrian campaign in 1142, John was wounded in a hunting accident in Cilicia and died in April 1143. His policy of turning Byzantium's claim to Antioch into real political power was continued by his son Manuel. Kinnamos, Choniates and William of Tyre are the main sources.
