Although there are many valuable studies about the early history of the Turkoi, i.e. Magyars, such as the important study of C. Macarteny, The Magyars in the Ninth Century (Cambridge 1930); G.Moravcsik, Byzantium and the Magyars (Amsterdam 1970), and others, the important and useful account of Constantine Porphyrogenitus about the history of the Magyars still needs more analysis. Macarteny presented a good presentation about the Magyars' account of DAI, but he was more concerned with the discussion of the home-land of the Magyars, Lebedia and Atelkozou, and the different shapes of their name in the Byzantine sources. G. Vernadsky in 1939 presented an interesting study about Lebedia and its relation with southern Russia.
DAI draws a good image about the immigrations of the Magyars from the east of the Pontus to the west and shows their political and social developments during their journey.
This paper will deal with the account of DAI about the Magyars and will try to find answers to some questions: Why did the Magyars ally with the Khazars, and what was the nature of this alliance? Why the Magyars did not fight with the Khazars against the Pechenegs? Were the Magyars, according to Constantine VII, under the Khazarian sovereignty? What was the nature of Byzantine-Hungarian relations at the end of the ninth century?
