Constantine was the intended heir of Basil, and as such received much attention from him, and accompanied him on military campaigns; whereas his younger brother,
Leo VI (), was made co-emperor merely to secure the imperial lineage and bolster legitimacy. However, Constantine died of fever on 3 September 879, before his father. After his death, Leo became the primary heir, and another brother,

() as Basil's only legitimate son. Most modern scholars doubt the accuracy of such claims, considering Leo as the legitimate son of Basil and Eudokia.
Tougher in his 1994 Ph.D. thesis supports the theory that Constantine was the son of Basil and Eudokia. In his later 1997 work, he argues against much of the reasoning behind considering Constantine to be Maria's son but does not definitively state a mother for Constantine. In his 1994 work, he points out that many Byzantine chroniclers consider Constantine to be the son of Basil, and that many historians use an argument that Constantine is Maria's son as a tool to explain why, Leo, but not Constantine, is said to be hated by Basil, as Basil would therefore consider Constantine his true son. He also argues that Alexander, who could not possibly be Michael's son by virtue of being born after his death, was not elevated in place of Constantine and Leo, suggesting either Basil believed them both to be his own sons, or else was not bothered by them not being such, and that Michael does not seem to have viewed Leo in any paternal way, stating that "this in itself is telling". Tougher questions the arguments that preclude Constantine from being the son of Eudokia, by arguing that if he was born after the marriage of Eudokia and Basil, he would have been too young to campaign with his father in 878; he argues that, given the issues related to the chronology of the marriage of Basil and Eudokia, it is possible that Constantine would be of fighting age. Historian
Arnold J. Toynbee argues that parents may have different feelings for sons, and the difference of personality is as likely as different mothers to explain why Basil preferred Constantine to Leo.
In his 1997 work, Tougher points out that Mango's reconstruction is ingenious, but convoluted, arguing that Michael could simply have adopted Constantine, rather than enacting a conspiracy to have his child, who he could not have known would be male, born in the purple. This is further reinforced by the fact that Alexander was only made emperor in 879, after Constantine's death. Tougher also points out that Leo VI advocated bringing the son of noblemen, called "noble whelps", on campaigns in his ''
Tactica'', the same term that the ''
Life of Basil'' uses for Constantine in its narrative of the 878 campaign; therefore stating that it was possible Constantine may have been 13/14 at the time, and therefore the son of Eudokia. Adontz argues that Constantine must have been born around 855, and is, therefore, the son of Maria, in order to be engaged to
Ermengard of Italy, the daughter of
Holy Roman Emperor Louis II (), however, Tougher argues that this engagement reflects that more of a child's engagement than a true marriage, and that, given that many Byzantine men were married at age 15, this may point to him being younger.

Constantine VII Porphyrogenitus (; 17 May 905 – 9 November 959) was the fourth Emperor of the Macedonian dynasty of the Byzantine Empire, reigning from 6 June 913 to 9 November 959. He was the son of Emperor Leo VI and his fourth wife, Zo ...

exclude information regarding Basil's first marriage to Maria. Constantine VII states that all of his aunts and uncles were the legitimate children of Basil and Eudokia, while Leo goes further, stating that Basil and Eudokia produced children before being married to each other. Constantine VII gives an idealized version of Basil's reign, stating that when Basil was crowned at the Hagia Sophia, he was followed by a chariot containing Eudokia, Constantine, and Leo, and that both Constantine and Leo were crowned at the same time as Basil, in 867, which no other source agrees with. Anti-Macedonian sources, such as Symeon Logothete, usually assume that Constantine was the son of Eudokia, and provide information regarding the alleged infidelity of Eudokia, and the arrangement between Michael and Basil.
Later life
Basil rose to co-emperor by convincing Michael that his uncle
Bardas was plotting against him and after slaying Bardas with Michael's blessing, was crowned on 26 May 866. Tensions between Basil and Michael built up, and Basil feared that he would be replaced, as Michael had threatened to make the
Basiliskianos emperor instead. Therefore, on the night of 23/24 September 867, Basil and his conspirators murdered him in his bed, making Basil the sole emperor.
Constantine, along with the rest of his brothers, was educated by
Photios, later the
Patriarch of Constantinople

; Photios may also have been the
godfather of Constantine, although some sources, such as Tougher, believe Photios was the godfather of Leo, rather than Constantine. Constantine is thought to have received more direct education and attention from Basil, whereas his other brothers may have been accompanied by court eunuchs. Constantine was made co-emperor by Basil in , and was his intended heir. Some historians date the

to 6 January 868, the
Feast of Epiphany, but there is no certainty of this; the ceremony could also have taken place on 25 December 867. Although Leo was raised to co-emperor on 6 January 870, Tougher views it likely that although Leo technically shared in imperial status, he was intended to live a life of obscurity, existing only to secure the imperial succession, much as Alexander later would under Leo himself.

take the position that they married, however, Tougher (1994) argues that there is no evidence he ever married. Constantine served in military campaigns alongside his father, in order to prepare him to be a military leader, including a campaign in
Syria, for which he shared a

. Constantine is mentioned as Emperor in The Acts of the
Eighth Ecumenical Council. He also appears, bearing the title , on numerous coins, alongside Basil and other members of his family.
Death
Constantine died unexpectedly of fever on 3 September 879, leaving Leo as the primary heir. Basil was severely effected by Constantine's death, and declared a period of mourning after this, possibly lasting up to six months. Notably, much of the coinage made after his death focuses upon him. Jenkins states that after Constantine's death "Basil went out of mind, and continued during the next seven years to be subject to fits of derangement," and relates that Basil became violent and contemptuous toward Leo, whom he "had never cared for", despising his "bookish youth"; Tougher considers this "at best, an overstatement." Tougher does concede that pro-Macedonian sources have an obvious bias in declaring that Basil recovered "manfully, inspired by the example of
Job", but believes Basil's shock was due more to the loss of an heir which Basil had trained well, and expected to succeed him, rather than true favoritism. Basil also had Constantine declared a saint by Photios I, the Patriarch of Constantinople, confirmed by the ''
Synaxarion of Constantinople''. The ''

was supposedly able to summon the ghost of Constantine for Basil.
After the death of Constantine, Basil focused upon securing his dynasty by marrying Leo to
Theophano Martinakia, in order for them to produce heirs, and Tougher (1994) remarks that Basil may even have become overprotective, shielding his remaining children from warfare. Additionally, Alexander is believed to have been crowned emperor following Constantine's death, in 879. Leo was imprisoned and stripped of imperial rank by Basil in 883, allegedly for his plans to usurp him, whereafter Alexander appears to have become the heir, until July 886, when Leo was released and restored as emperor. Just a month later, on 29 August 886, Basil died of wounds from a hunting trip, and Leo succeeded him.
