Synopsis
A History of the Eastern Roman Empire: From the Fall of Irene to the Accession of Basil I by J.B. Bury is a definitive, deeply detailed work of historical scholarship covering a crucial but often overlooked transition period in Byzantine history. Published in 1912, the book bridges the gap between Bury’s earlier works and his edition of Edward Gibbon’s history. It focuses strictly on the years 802 to 867 AD, a turbulent era that witnessed the end of the Isaurian dynasty with the deposition of Empress Irene, weathered the final fractures of the Iconoclastic controversy, and concluded with the rise of the influential Macedonian dynasty under Basil I.
Bury approaches this sixty-five-year interval with a focus on internal administrative reform, ecclesiastical politics, and foreign relations. He meticulously charts the reigns of emperors like Nicephorus I, Leo V, and Michael III "the Drunkard," challenging the traditional narrative that this era was merely one of stagnation and moral decay. Instead, Bury highlights how the empire consolidated its provincial theme system, reorganized its finances, and successfully defended its borders against formidable external threats. A significant portion of the text is dedicated to Byzantium’s complex foreign affairs, including the brutal and shifting wars with the Bulgar Khanate under Krum, ongoing naval and territorial struggles with the Saracens in Sicily and Crete, and the critical diplomatic mission of Saints Cyril and Methodius, which expanded Byzantine cultural and religious influence into the Slavic world.
Beyond military and political maneuvers, Bury provides a thorough examination of the intellectual and social life of the 9th-century empire. He details the final phase of Iconoclasm, leading up to the definitive restoration of icons in 843 AD under Empress Theodora, and explores how these religious struggles shaped the power dynamic between the Patriarchate of Constantinople and the imperial throne. The book concludes by illustrating how the artistic, educational, and military foundations laid during this brief, intense era directly paved the way for the golden age of the Macedonian dynasty, securing the Eastern Roman Empire's position as the preeminent cultural and political power of early medieval Europe.
