The accession of Baldwin II saw the revival of the Byzantine tradition of 'porphyrogenetos', as his father had briefly ruled as emperor in 1217. During his long reign Baldwin assisted the armies of the Nicaean empire in their expansion westwards, but he was unable to protect his own empire, and Constantinople was retaken for the Byzantines by the forces of Michael Palaeologus in 1261. Baldwin fled to the west, eventually forming an alliance with Charles of Anjou at the treaty of Viterbo in 1267.
