5. KONSTANTINOS Doukas Palaiologos porphyrogennetos (after 1261-5 Mar 1306). Pachymeres names "tertium…natum in purpura Constantinum" as the son of Emperor Mikhael VIII, recording his later disgrace[137]. Ioannes Kantakouzenos records that "Michaeli primo Romanorum imperatori Palaeologo" had "filii nati tres Andronicus…Constantinus Porphyrogenitus et Theodorus"[138]. Georgios Phrantzes names "Andronicum imperatorum et Constantinum Porphyrogenitum" as the two sons of Emperor Mikhael VIII[139]. He inherited 60,000 hyperpyra from his father and boasted of his intention to amass a fortune of nearly double that amount before he died[140]. As part of his brother's campaign against the Turks in 1290, Konstantinos led an army which based itself at Nymphaion where it was alleged that he plotted against the emperor. He was tried, condemned and taken back to Constantinople as a prisoner. Pachymeres records the death of "Porphyrogenitum" in prison "quinta dies mensis eiusdem" (which appears from the context to refer to the month of March), as a monk named ATHANASIOS[141].

In a later passage, Pachymeres clarifies her parentage when he records that the "avia paterna" of "coniux Porphyrogeniti" was "Strategopulinæ neptis ex fratre"[143]. Her birth date is estimated from her marriage in [1291]. If correct, it suggests that her father must have been one of his parents’ youngest children.

 Konstantinos Palaiologos & his wife had one child:
