Constantine Palaiologos

Constantine Palaiologos (1278/1281–1334/1335) was the second son of Emperor Andronikos II, a purple-born prince made Despot in 1294 on his marriage to Eudokia.

In 1305 he fought under his brother Michael IX at the rout of Apros against the Catalan Company, and in 1317 turned back his half-sister Simonis, who had fled Serbia for a monastery. A second marriage to another Eudokia was also childless, though he had an illegitimate son, Michael.

He governed Avlona and Thessalonica until his nephew Andronikos III imprisoned him. He died as the monk Kallistos in 1334 or 1335.
