ABSTRACT

The Roman Empire in the east, which we call Byzantine, was much longer lived than

other empires in the near east or Europe, surviving for about a thousand years. During

that exceptional span of existence, periods of military expansion, notably under Justinian

in the sixth century and under the Macedonian dynasty (870 to 1070), alternated with

periods of great difficulty and loss of power. During much of their history the Byzantines

were militarily, and in other ways, on the defensive, and were confronted with an

expanding Islam which was more powerful than they were. Their ability to maintain their

brilliant civilization in such difficult circumstances for so long, and actually to spread it

far and wide among more primitive peoples beyond the limits of their rule, must still

excite our admiration. The means they used are very pertinent to our study.
