History of the Eastern Roman Empire surveys Byzantium from the fall of Irene to the accession of Basil I (802–867), following rulers from Nikephoros I and Leo V to Theophilos and the regency of Theodora. Bury balances narrative with chapters on administration, finance, court ritual, and the Church, culminating in the end of Iconoclasm. In lucid, restrained prose grounded in chronicles, law, coins, and seals, he corrects Gibbon's biases and reframes Byzantine statecraft. J. B. Bury (1861–1927), an Irish classicist and later Regius Professor at Cambridge, applied a positivist, source-driven method refined as editor of Gibbon and historian of Late Antiquity. Fluent in Greek and attentive to German and French Byzantinists, he fused philology with institutional analysis. This volume extends his earlier Later Roman Empire, reflecting a lifelong bid to integrate the medieval Roman East into European history. Scholars and serious readers will value this precise, judicious guide to ninth-century Constantinople. Clear structure, robust notes, and attention to economic and military mechanisms make it an indispensable entry point into how theology, bureaucracy, and war reshaped a still-Roman empire.
