Following the success of the First Crusade and the failure of the Crusade of 1101, the Turks resumed their offensive operations against the Byzantines. Emperor Alexios I Komnenos, suffering from old age, was unable to deal with the swift Turkish raids into what was left of Byzantine Anatolia. However, the Seljuk Sultanate of Rum was finally brought to battle when it unsuccessfully laid siege to Nicaea.
