Constantinople to take service with Vataces. At the commencement of his reign he was attacked by the newly appointed emperor, Robert of Courtenay, and in the combat which ensued not only was Vataces successful, but the last of the knights who had taken part in the capture of the city were left dead on the field. Until Robert's death in 1228, Nicaea had few troubles with the Latin empire.
