Lost to the West: The Forgotten Byzantine Empire That Rescued Western Civilization

Only the threat of the Seljuk Turks at their rear prevented the Nicaean emperors from further exploiting Latin weakness; but in 1242, a terrifying Mongol horde suddenly appeared, and the situation dramatically changed. Smashing the Turkish army sent against him, the Mongol khan forced the Seljuk sultan to become his vassal and extracted a promise of an annual tribute of horses, hunting dogs, and gold. The Mongol horde seemed poised to descend on Nicaea next, but it unexpectedly withdrew the next year, leaving the Seljuks crippled in his wake. To the relieved Byzantines, it seemed as if God had delivered them from certain destruction, and perhaps even given them a powerful new ally. Nestorian Christians who had been expelled from the Byzantine Empire had reached Mongolia in the seventh century, and though the khans had yet to embrace a major religion, several high-ranking Mongols—including the daughter-in-law of Genghis Khan—were Christian. In any case, whether they were well disposed to Christianity or not, the Mongols’ timely attack finally left Nicaea free to pursue its dream of recapturing Constantinople.

Through careful diplomacy and military displays, Nicaea slowly built up the pressure on the tottering Latin Empire. By now the crusader kingdom had virtually shrunk down to Constantinople itself, and the capital lived under a perpetual shadow of gloom, with its deserted streets and dilapidated palaces. Its humiliated emperor Baldwin II was so impoverished that he’d been obliged to sell off the lead from the roof of the imperial palace—which was now in a tumbledown state of advanced decay—and in his desperate search for money had even begun to pawn the few relics that had survived the sack. By 1259, when a dashing young general named Michael Palaeologus was crowned in Nicaea, Baldwin was barely clinging on to power, and few doubted the general would recover the city. The only question was when.

Nicaea was not without its own turmoil. The thirty-four-year-old Michael Palaeologus had come to power only after the regent was brutally hacked to death during the funeral service of his predecessor, but by the time Michael was crowned on Christmas day, his empire was infinitely more powerful and vibrant than its Latin counterpart. In the summer of 1261, Michael neutralized the threat of the Venetian navy by signing a treaty with their archrivals Genoa, and sent his Caesar, Alexius Strategopoulos, to see how strong Constantinople’s defenses were. When the Caesar arrived outside the city in July with eight hundred men, some farmers immediately informed him that the Latin garrison—along with the Venetian navy—was away attacking an island in the Bosporus. Hardly believing his luck, Strategopoulos hid until nightfall in a monastery near the Pege Gate, easily escaping detection by the laconic defenders. Upon discovering a small, unlocked postern gate nearby, the Caesar sent through a handful of men who quietly overpowered the guards and opened the main gate. On the morning of July 25, 1261, the Nicaean army poured into the city, shouting at the top of their lungs and beating their swords against their shields. Emperor Baldwin II was so terrified by the noise that he left the crown jewels behind, fleeing to the palace of the Bucoleon, where he was somehow able to find a Venetian ship and make good his escape. Within hours, it was all over. The Venetian quarter was burned to the ground, and the returning Venetian navy was too busy rescuing its loved ones to fight back.

For the Latins inside the city, there was no thought of resistance, only of panicked flight. Scattering in all directions, they hid in churches, disguised themselves as monks, and even leaped into the sewers to avoid detection. When they cautiously emerged, however, they found that there had been no massacre. The Byzantines had come home not to plunder but to live. The bedraggled Latins hurried quietly down to the harbors and boarded the returning Venetian ships, glad that Byzantines had shown more restraint in victory than their own crusading predecessors.

The incredible news reached Michael Palaeologus where he was asleep in his tent, nearly two hundred miles away. Refusing to believe that his forces had captured the city until he had seen Baldwin’s discarded scepter, Michael hurried to take possession of the capital that he had long dreamed of but never seen. On August 15, 1261, he solemnly entered through the Golden Gate and walked to the Hagia Sophia, where he was crowned as Michael VIII. After fifty-seven years in exile, the Byzantine Empire had come home.
