1453: Constantinople and the Immortal Rulers

by Billy Cotsis

Overview

Experience the final days of Byzantium as history itself comes alive—where courage, innovation, and empire collide in a world on the brink of change.

Witness the fall of an empire through the eyes of those who lived it.

Emperor Constantine Palaiologos stands atop the legendary Theodosian Walls, facing Sultan Mehmed II’s massive army. With just 7,000 defenders against 120,000 invaders, the emperor must rely on an unlikely coalition: Giovanni Giustiniani’s Genoese warriors, Grant the Scottish engineer, Captain Michalis’s fierce Cretans, and Theodora, his trusted emissary racing against time. As Orban’s colossal cannons thunder against walls that have stood for a millennium, the fate of East and West hangs by a thread.

Billy Cotsis brings the siege of Constantinople to life with vivid, human detail, blending historical accuracy with the grit, fear, and courage of those who fought for civilization itself. Through the perspectives of both Christian and Muslim combatants, including the intimate chronicles of George Sphrantzes, the novel explores loyalty, faith, and the price of empire while capturing the technological revolution reshaping medieval warfare.

As the final assault begins on May 29, 1453, heroes emerge from every corner of the city—but with Venetian ships on the horizon and Ottoman banners flying over breached towers, will Constantine’s desperate gamble save Rome’s last remnant, or will the city finally succumb to history?

An epic of courage, cunning, and the human spirit at the end of an era.
