John Cantacuzene reigned as Byzantine emperor in Constantinople from 1347 to 1354. A man of varied talents, as a scholar, soldier, statesman, theologian and monk, he was unique in being the only emperor to narrate the events of his own career. His memoirs form one of the most interesting and literate of all Byzantine histories. Following his abdication in 1354, he lived the last thirty years of his life as a monk, a writer and a grey eminence behind the throne. This book is not a social or political history of the Byzantine Empire in the fourteenth century. It is a biography of a much maligned man who had a hope, however naive, of coming to terms with the emerging Muslim world of Asia and of winning the co-operation of western Christendom without compromising the Orthodox faith of the Byzantine tradition.

With The Emperor and the Army in the Later Roman Empire, AD 235–395 Mark Hebblewhite offers the first study solely dedicated to examining the nature of the relationship between the emperor and his army in the politically and militarily volatile later Roman Empire. Bringing together a wide range of available literary, epigraphic and numismatic evidence he demonstrates that emperors of the period considered the army to be the key institution they had to mollify in order to retain power and consequently employed a range of strategies to keep the troops loyal to their cause. Key to these efforts were imperial attempts to project the emperor as a worthy general (imperator) and a generous provider of military pay and benefits. Also important were the honorific and symbolic gestures each emperor made to the army in order to convince them that they and the empire could only prosper under his rule.
