Constantine Palaiologos (half-brother of Michael VIII)

Constantine was born c. 1230, to Andronikos Palaiologos, Grand domestic of the Empire of Nicaea and his unknown second wife.

[1] The life of Constantine is unknown until 1259, when he was appointed Caesar by his elder half-brother, Michael VIII.

He commanded the Byzantine forces on an unsuccessful campaign against the Latin Principality of Achaea, where his army was routed at the Battle of Prinitza.

However, Constantine had already left the region by the time of the major Byzantine defeat at the Battle of Makryplagi in 1263/1264.

Constantine was married c. 1259/60 to Irene Komnene Laskarina Branaina,[5] by whom he seems to have had five children"
