'''De Administrando Imperio''' is the commonly used
Latin title of a scholarly work written in
Greek by the
10th-century Byzantine emperor Constantine VII.
Constantine was a scholar-emperor, who sought to revive learning and education in the
Byzantine Empire. He produced many other works, including ''
De Ceremoniis'', a treatise on the etiquette and procedures of the imperial court; and a biography of his grandfather,
Basil I. ''De Administrando Imperio'' was written between 948 and 952, as an internal and foreign policy manual for the use of his son and successor, the Emperor
Romanus II. It contains advice on running the ethnically-mixed empire as well as fighting external enemies. The work combines two of Constantine's earlier treatises, ''Περι εθνων'' (''Peri Ethnon''), concerning the histories and characters of the nations neighbouring the Empire, including the
Kievan Rus',
Arabs,
Lombards,
Armenians, and
Georgians; and ''Περι θεματων'' (''Peri Thematon''), concerning recent events in the imperial provinces. To this combination was added Constantine's own political instructions to his son Romanus.
The work describes the
Pechenegs,
Kievan Rus',
Turks,
Bulgarians,
Tatars, and
Khazars to the north; the
Arabs to the east and south and their expansion as far as
Spain; and the
Germans,
Lombards,
Venetians,
Dalmatians,
Croats,
Serbs, and
Moravians to the west. As well as historical and geographical information, which is often confused and filled with legend, Constantine gives information on how to manipulate each nation against each other, rather than use imperial money and resources to wage war against them directly. There is also information about imperial provinces, including
Armenia,
Iberia,
Cyprus, and the
Peloponnese, with recent diplomatic events which were considered useful for Romanus' instruction.
It was not intended for general publication, as it contains many state secrets (including
Greek fire, although, notably, not its ingredients) and is clearly written for Romanus' personal use. The earliest surviving copy was made by
John Doukas in the late 11th century. As a result, it is preserved fully in only three manuscripts (two of which are now located in
Bibliothèque Nationale in
Paris, and the third in the
Vatican Library), and only partially in a fourth (now located in
Modena). It was first published in
1611 by
Johannes Meursius, who gave it the Latin title by which it is now universally known, which translates as ''On Administering the Empire''. Constantine himself did not give the work a name. Among its later editors was
Jacques Paul Migne in the
Patrologia Graeca.
The latest critical edition was first proposed by
J.B. Bury, but was completed by Gyula Moravcsik and translated into English by Romily J.H. Jenkins in 1967.
