Constantine Palaiologos orPalaeologus (Greek:Κωνσταντῖνος Παλαιολόγος; 1261 – 5 May 1306) was aByzantine prince of thePalaiologos dynasty, who also served as a general in the wars against theSerbs andTurks.
Constantine was the third son of EmperorMichael VIII Palaiologos (r. 1259–1282) andTheodora Palaiologina. He was born in autumn 1261 inConstantinople, which had just been recovered from theLatin Empire in August. He was hence a trueporphyrogennetos ("purple-born") prince, and was often referred to as such. His father reportedly accorded him honours above even those of adespotes.[1]
In 1280, Constantine fought against theSerbs inMacedonia, and was then dispatched against theTurkish raiders inAsia Minor, where he was successful in clearing theMaeander River valley of their presence. He later rebuilt the famousMonastery of Stoudios inConstantinople. In 1293, he was slandered to his brother, EmperorAndronikos II Palaiologos (r. 1282–1328), and placed under arrest. He later became a monk, with themonastic nameAthanasios. He died at Constantinople on 5 May 1306, and was buried at theLips Monastery.[1]
From his marriage to Irene Palaiologina Raoulaina, he had one son, thepanhypersebastosJohn Palaiologos.[1]
