Constantine VII, renowned for his abilities as a writer and scholar, has written, or had commissioned, the works De Ceremoniis ("On Ceremonies"), describing the kinds of court ceremonies (also described later in a more negative light by Liutprand of Cremona); De Administrando Imperio ("On the Administration of the Empire"), giving advice on running the Empire internally and on fighting external enemies; and a history of the Empire covering events following the death of the chronographer Theophanes the Confessor in 817.
Among his historical works is a history eulogizing the reign and achievements of his grandfather, Basil I (Vita Basilii).
These books are insightful and of interest to the historian, sociologist, and anthropologist as a source of information about nations neighboring the Empire.
They also offer a fine insight into the Emperor himself.
Constantine has had active diplomatic relationships with foreign courts, including those of the caliph of Córdoba, Abd ar-Rahman III and of Otto I, Holy Roman Emperor.
Constantine had been visited by Olga of Kiev, regent of the Kievan Rus' in the autumn of 957.
The reasons for this voyage have never been clarified; but she had been baptized a Christian with the name Helena, and sought Christian missionaries to encourage her people to adopt Christianity.
Constantine VII dies at Constantinople in November 959.
It is rumored that Constantine had been poisoned by his daughter-in-law Theophano or his so, who now ascends the imperial throne as Romanos II.
A politically incapable ruler, he will leave affairs of state to the eunuch Joseph Bringas and military affairs to Nikephoros Phokas.
