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

Alexius immediately attacked, cobbling together no fewer than three mercenary armies, but each one met the same fate, and the emperor accomplished nothing more than further draining his treasury. Even without their charismatic leader, the Normans were clearly more than a match for his imperial forces, so Alexius began a search for allies to do the fighting for him. He found a ready one in Venice—that most Byzantine of sea republics—where the leadership was as alarmed as everyone else about the scope of Guiscard’s ambitions. In return for the help of its navy, Alexius reduced Venetian tariffs to unprecedented (and from native merchants’ perspectives rather dangerous) levels, and gave Venice a full colony in Constantinople with the freedom to trade in imperial waters. The concessions virtually drove Byzantine merchants from the sea, but that spring it must all have seemed worth it as the Venetian navy cut off Bohemond from supplies or reinforcements. By this time, the Normans were thoroughly exhausted. It had been nearly four years since they had landed in Byzantine territory, and though they had spectacularly demolished every army sent against them, they were no closer to conquering Constantinople than the day they arrived. Most of their officers were unimpressed by the son of Guiscard and wanted only to return home. Encouraged by Alexius’s shrewd bribes, they started to grumble, and when Bohemond returned to Italy to raise more money, his officers promptly surrendered.

The next year, in 1085, the seventy-year-old Robert Guiscard tried again, but he got no farther than the island of Cephalonia, where a fever accomplished what innumerable enemy swords couldn’t, and he died without accomplishing his great dream.^* The empire could breathe a sigh of relief and turn its eyes once more to lesser threats from the East.

The Muslim threat—much like the Norman one—had recently been tremendously diminished by a fortuitous death. At the start of Alexius’s reign, it had seemed that the Seljuk Turks would devour what was left of Asia Minor. In 1085, Antioch had fallen to their irresistible advance, and the next year Edessa and most of Syria as well. In 1087, the greatest shock came when Jerusalem was captured and the pilgrim routes to the Holy City were completely cut off by the rather fanatical new masters. Turning to the coast, the Muslims captured Ephesus in 1090 and spread out to the Greek islands. Chios, Rhodes, and Lesbos fell in quick succession. But just when it appeared as if Asia was lost, the sultan died and his kingdom splintered in the usual power grab.

With the Norman threat blunted and the Muslim enemy fragmented, the empire might never have a better opportunity to push back the Seljuk threat—and Alexius knew it. All the emperor needed was an army, but as the recent struggle with the Normans had shown, his own was woefully inadequate. Alexius would have to turn to allies to find the necessary steel to stiffen his forces, and, in 1095, he did just that. Taking pen in hand, he wrote a letter to the pope.

The decision to appeal to Rome was somewhat surprising in light of the excommunication of forty-one years before, but most of those involved in that unfortunate event were long dead, and tempers had cooled in the ensuing decades. The emperor and the pope might quibble occasionally about theological details, but they were members of the same faith, and it was as a fellow Christian that Alexius wrote Urban. As a gesture of goodwill to get things off on the right foot, the emperor reopened the Latin churches in Constantinople, and when his ambassadors reached Pope Urban II, they found the pontiff to be in a conciliatory mood. The appalling Turkish conquests had profoundly shocked him, and the sad plight of eastern Christians under Muslim rule could no longer be ignored. No record of the conversation that followed has survived, but by the time the pope made his way to France a few months later, a grand new vision had formed in his mind. Islam had declared a jihad to seize the holy places of Christendom and spread its faith into Europe; now it was time for a grand Christian counteroffensive. On November 18, the pope mounted a huge platform just outside the French city of Clermont and delivered one of the most fateful speeches in history.

The Saracens, he proclaimed, had come storming out of the deserts to steal Christian land and defile their churches, murdering Christian pilgrims and oppressing the faith. They had torn down the Church of the Holy Sepulchre in Jerusalem and forced innumerable believers to convert to Islam. The West could no longer in good conscience ignore the suffering—it was the sacred duty of every Christian to march to the aid of their eastern brothers. The Saracens had stolen the city of God and now righteous soldiers were needed to drive them out. All those who marched with a pure heart would have their sins absolved.
