Constantine VII Porphyrogennetos or Porphyrogenitus, "the Purple-born" (Greek: Κωνσταντίνος Ζ΄ Πορφυρογέννητος, Kōnstantinos VII Porphyrogennētos), (Constantinople, 905 – November 9, 959 in Constantinople) was the son of the Byzantine emperor Leo VI and his fourth wife Zoe Karbonopsina. He was also the nephew of the Emperor Alexander. He is famous for his two descriptive books, De Administrando Imperio and De Ceremoniis.
Porphyrogennētos or Porphyrogenitus (Greek: Πορφυρογέννητος), literally "born in the Purple" was a title given to a son or daughter (Porphyrogenneta) of a reigning Emperor in the (Roman) Byzantine Empire.
His nickname alludes to the Purple Room of the imperial palace, decorated with the rare stone porphyry, where legitimate children of reigning emperors were normally born. Constantine was also born in this room, although his mother Zoe had not been married to Leo at that time. Nevertheless, the epithet allowed him to underline his position as the legitimized son, as opposed to all others who claimed the throne during his lifetime.
