The first biography of the last Byzantine Emperor.

Constantine XI’s last moments in life, as he stood before the walls of Constantinople in 1453, have bestowed a heroic status on him. This book produces a more balanced portrait of an intriguing individual: the last emperor of Constantinople. To be sure, the last of the Greek Caesars was a fascinating figure, not so much because he was a great statesman, as he was not, and not because of his military prowess, as he was neither a notable tactician nor a soldier of exceptional merit. This monarch may have formulated grandiose plans but his hopes and ambitions were ultimately doomed, because he failed to inspire his own subjects, who did not rally to his cause. Constantine lacked the skills to create, restore, or maintain harmony in his troubled realm. In addition, he was ineffective on the diplomatic front, as he proved unable to stimulate Latin Christendom to mount an expedition and come to the aid of south-eastern Orthodox Europe. Yet in sharp contrast to his numerous shortcomings, his military defeats, and the various disappointments during his reign, posterity still fondly remembers the last Constantine.

A major study and an essential reference work, this book presents a critical evaluation of the sources on the fall of Constantinople to the Ottoman Turks in 1453. In Part I: The Pen, drawing upon manuscript and printed sources, and looking at the contrasting interpretations in secondary works, the authors reassess the written evidence concerning the event. In Part II, The Sword, the investigation results in new conclusions concerning the layout of the Theodosian Walls, the offensive and defensive strategies of the Byzantines and Turks, including land and sea operations, and an analysis of some of the major engagements.

From the New York Times–bestselling “standard-bearer for alternate history”: A spy takes on the enemies of the Byzantine Empire (USA Today). In another, very different timeline—one in which Mohammed embraced Christianity and Islam never came to be—the Byzantine Empire still flourishes in the fourteenth century, and wondrous technologies are emerging earlier than they did in our own. Having lost his family to the ravages of smallpox, Basil Argyros has decided to dedicate his life to Byzantium. A stalwart soldier and able secret agent, Basil serves his emperor courageously, going undercover to unearth Persia’s dastardly plots and disrupting the dark machinations of his beautiful archenemy, the Persian spy Mirrane, while defusing dire threats emerging from the Western realm of the Franco-Saxons. But the world Basil so staunchly defends is changing rapidly, and he must remain ever vigilant, for in this great game of empires, the player who controls the most advanced tools and weaponry—tools like gunpowder, printing, vaccines, and telescopes—must certainly emerge victorious. A collection of interlocking stories that showcase the courage, ingenuity, and breathtaking derring-do of superspy Basil Argyros, Agent of Byzantium presents the great Harry Turtledove at his alternate-world-building best. At once intricate, exciting, witty, and wildly inventive, this is a many-faceted gem from a master of the genre.
