Best Books on the Byzantine Emperors

The best books on the Byzantine emperors treat the Eastern Roman Empire as what it actually was: not a postscript to Rome but a continuous civilisation that lasted eleven hundred years, produced some of history's most complex political operators, and preserved Greek and Roman knowledge through the period when Western Europe lost it. The word "Byzantine" has come to mean needlessly complicated in everyday English. The empire earned that reputation.

The reading challenge is that Byzantine history is long, its emperors number in the dozens, and many of the best primary sources exist only in partial translations or academic editions. The guide below prioritises books accessible to general readers while covering the major periods and figures that actually shaped the empire's history.

Where to Start: The Best Single-Volume Introduction

The best starting point for Byzantine history is Byzantium: The Surprising Life of a Medieval Empire by Judith Herrin. Herrin is a professor of Byzantine history at King's College London, and she structures the book thematically rather than chronologically, which solves the problem that most introductory Byzantine histories run into: a chronological tour of ninety-plus emperors is not readable. By organising around themes like law, religion, trade, and military culture, Herrin gives you the texture of Byzantine civilisation before the emperor-by-emperor detail becomes meaningful.

Read Herrin first. Every other book in this guide will make more sense after it.

Justinian I: The Emperor Who Almost Reunited Rome

Justinian I (reigned 527 to 565) is the most written-about Byzantine emperor for good reason. He reconquered North Africa, Italy, and parts of Spain. He commissioned the Hagia Sophia. He codified Roman law in the Corpus Juris Civilis, the foundation of legal systems across Europe. He also presided over the Plague of Justinian, possibly history's first pandemic of bubonic plague, and he governed alongside his wife Theodora, an ex-actress from the lower classes who became one of the most consequential women in Byzantine history.

Justinian's Flea by William Rosen

Justinian's Flea by William Rosen covers Justinian's reign through the lens of the plague that struck in 541 CE. Rosen is a science writer as much as a historian, and his treatment of the disease, its origins in Central Asia, its spread through the empire's trade networks, and its demographic consequences gives the book a modern relevance that pure political biographies of Justinian lack. The title is memorable, the argument is serious: the plague may have destroyed Justinian's reconquest project more decisively than any military defeat.

Theodora: Actress, Empress, Saint by David Potter

Potter's biography of Theodora is the most complete account of her life available in English. He separates the hostile primary sources (principally Procopius's Secret History, which is Byzantine court gossip at its most vicious) from what can be corroborated, and constructs a careful account of how a woman with no conventional claim to power became co-ruler of the empire. The book is also a useful introduction to how Byzantine court politics worked.

The Middle Byzantine Period: Military Expansion and Cultural Flowering

The ninth and tenth centuries produced the Macedonian dynasty, which historians often call Byzantium's golden age. The empire expanded into Bulgaria, Mesopotamia, and parts of Syria. The Varangian Guard was established. Byzantine missionaries converted the Slavic peoples and created the Cyrillic alphabet. Art, theology, and scholarship flourished in Constantinople while Western Europe was still rebuilding from the Carolingian collapse.

John Julius Norwich's three-volume A History of Byzantium (published as A Short History of Byzantium in the abridged one-volume edition) covers this period with the most complete narrative treatment available for general readers. Norwich is not an academic historian but he read the sources carefully and writes with clarity. His abridged single volume is the practical option for most readers.

The Komnenian Restoration and Anna Komnene

The Komnenian dynasty (1081 to 1185) is notable partly because it produced one of the most remarkable primary sources in medieval history: The Alexiad, written by Anna Komnene, daughter of Emperor Alexios I. Anna Komnene was the first female historian in recorded history. She wrote a detailed account of her father's reign that covers the First Crusade from the Byzantine perspective, the political intrigues of the Komnenian court, and military campaigns across the Balkans and Anatolia. The Penguin Classics edition with E.R.A. Sewter's translation is the accessible version for modern readers.

The Fall of Constantinople, 1453

The fall of Constantinople to Mehmed II in May 1453 is one of history's most precisely documented endings. The city had been under siege for fifty-three days. Constantine XI was the last emperor. When the walls were breached, he reportedly threw off his imperial regalia and died fighting. The Ottoman cannon that breached the Theodosian Walls had been cast by a Hungarian engineer named Urban who had first offered his services to the Byzantines, who could not afford him.

Roger Crowley's Constantinople: The Last Great Siege, 1453 covers the siege in the kind of military and eyewitness detail that makes the fall feel as immediate as a contemporary report. Crowley uses Byzantine, Ottoman, Venetian, and Genoese sources, because the defense was as multinational as any medieval coalition, and the result is the most complete and readable account of the siege available in English.

Three Books to Read First

• Byzantium: The Surprising Life of a Medieval Empire by Judith Herrin is the thematic introduction that makes the entire Byzantine period legible before you attempt any deeper reading.
• Justinian's Flea by William Rosen covers the most pivotal reign in Byzantine history through the double lens of political ambition and pandemic, and it reads faster than its depth suggests.
• Constantinople: The Last Great Siege by Roger Crowley is the finest narrative account of the empire's final weeks, grounded in multiple primary sources and written with genuine momentum.
