The Real History of the Crusades

The crusades are quite possibly the most misunderstood event in European history. Most of what passes for public knowledge about it is either misleading or just plain wrong

Misconceptions about the Crusades are all too common. The Crusades are generally portrayed as a series of holy wars against Islam led by power-mad popes and fought by religious fanatics. They are supposed to have been the epitome of self-righteousness and intolerance, a black stain on the history of the Catholic Church in particular and Western civilization in general. A breed of proto-imperialists, the Crusaders introduced Western aggression to the peaceful Middle East and then deformed the enlightened Muslim culture, leaving it in ruins. For variations on this theme, one need not look far. See, for example, Steven Runciman's famous three-volume epic, History of the Crusades, or the BBC/A&E documentary, The Crusades, hosted by Terry Jones. Both are terrible history yet wonderfully entertaining.

So what is the truth about the Crusades? Scholars are still working some of that out. But much can already be said with certainty. For starters, the Crusades to the East were in every way defensive wars. They were a direct response to Muslim aggression—an attempt to turn back or defend against Muslim conquests of Christian lands.

From the safe distance of many centuries, it is easy enough to scowl in disgust at the Crusades. Religion, after all, is nothing to fight wars over.

Christians in the eleventh century were not paranoid fanatics. Muslims really were gunning for them. While Muslims can be peaceful, Islam was born in war and grew the same way. From the time of Mohammed, the means of Muslim expansion was always the sword. Muslim thought divides the world into two spheres, the Abode of Islam and the Abode of War. Christianity—and for that matter any other non-Muslim religion—has no abode. Christians and Jews can be tolerated within a Muslim state under Muslim rule. But, in traditional Islam, Christian and Jewish states must be destroyed and their lands conquered. When Mohammed was waging war against Mecca in the seventh century, Christianity was the dominant religion of power and wealth. As the faith of the Roman Empire, it spanned the entire Mediterranean, including the Middle East, where it was born. The Christian world, therefore, was a prime target for the earliest caliphs, and it would remain so for Muslim leaders for the next thousand years.

With enormous energy, the warriors of Islam struck out against the Christians shortly after Mohammed's death. They were extremely successful. Palestine, Syria, and Egypt—once the most heavily Christian areas in the world—quickly succumbed. By the eighth century, Muslim armies had conquered all of Christian North Africa and Spain. In the eleventh century, the Seljuk Turks conquered Asia Minor (modern Turkey), which had been Christian since the time of St. Paul. The old Roman Empire, known to modern historians as the Byzantine Empire, was reduced to little more than Greece. In desperation, the emperor in Constantinople sent word to the Christians of western Europe asking them to aid their brothers and sisters in the East.
That is what gave birth to the Crusades. They were not the brainchild of an ambitious pope or rapacious knights but a response to more than four centuries of conquests in which Muslims had already captured two-thirds of the old Christian world. At some point, Christianity as a faith and a culture had to defend itself or be subsumed by Islam. The Crusades were that defense.

Pope Urban II called upon the knights of Christendom to push back the conquests of Islam at the Council of Clermont in 1095. The response was tremendous. Many thousands of warriors took the vow of the cross and prepared for war. Why did they do it? The answer to that question has been badly misunderstood. In the wake of the Enlightenment, it was usually asserted that Crusaders were merely lacklands and ne'er-do-wells who took advantage of an opportunity to rob and pillage in a faraway land. The Crusaders' expressed sentiments of piety, self-sacrifice, and love for God were obviously not to be taken seriously. They were only a front for darker designs.

The Crusades were wars, so it would be a mistake to characterize them as nothing but piety and good intentions. Like all warfare, the violence was brutal (although not as brutal as modern wars). There were mishaps, blunders, and crimes. These are usually well-remembered today. During the early days of the First Crusade in 1095, a ragtag band of Crusaders led by Count Emicho of Leiningen made its way down the Rhine, robbing and murdering all the Jews they could find. Without success, the local bishops attempted to stop the carnage. In the eyes of these warriors, the Jews, like the Muslims, were the enemies of Christ. Plundering and killing them, then, was no vice. Indeed, they believed it was a righteous deed, since the Jews' money could be used to fund the Crusade to Jerusalem. But they were wrong, and the Church strongly condemned the anti-Jewish attacks.

Fifty years later, when the Second Crusade was gearing up, St. Bernard frequently preached that the Jews were not to be persecuted:


Ask anyone who knows the Sacred Scriptures what he finds foretold of the Jews in the Psalm. "Not for their destruction do I pray," it says. The Jews are for us the living words of Scripture, for they remind us always of what our Lord suffered.... Under Christian princes they endure a hard captivity, but "they only wait for the time of their deliverance."

Nevertheless, a fellow Cistercian monk named Radulf stirred up people against the Rhineland Jews, despite numerous letters from Bernard demanding that he stop. At last Bernard was forced to travel to Germany himself, where he caught up with Radulf, sent him back to his convent, and ended the massacres.

It is often said that the roots of the Holocaust can be seen in these medieval pogroms. That may be. But if so, those roots are far deeper and more widespread than the Crusades. Jews perished during the Crusades, but the purpose of the Crusades was not to kill Jews. Quite the contrary: Popes, bishops, and preachers made it clear that the Jews of Europe were to be left unmolested. In a modern war, we call tragic deaths like these "collateral damage." Even with smart technologies, the United States has killed far more innocents in our wars than the Crusaders ever could. But no one would seriously argue that the purpose of American wars is to kill women and children.

By any reckoning, the First Crusade was a long shot. There was no leader, no chain of command, no supply lines, no detailed strategy. It was simply thousands of warriors marching deep into enemy territory, committed to a common cause. Many of them died, either in battle or through disease or starvation. It was a rough campaign, one that seemed always on the brink of disaster. Yet it was miraculously successful. By 1098, the Crusaders had restored Nicaea and Antioch to Christian rule. In July 1099, they conquered Jerusalem and began to build a Christian state in Palestine. The joy in Europe was unbridled. It seemed that the tide of history, which had lifted the Muslims to such heights, was now turning.

But it was not. When we think about the Middle Ages, it is easy to view Europe in light of what it became rather than what it was. The colossus of the medieval world was Islam, not Christendom. The Crusades are interesting largely because they were an attempt to counter that trend. But in five centuries of crusading, it was only the First Crusade that significantly rolled back the military progress of Islam. It was downhill from there.

When the Crusader County of Edessa fell to the Turks and Kurds in 1144, there was an enormous groundswell of support for a new Crusade in Europe. It was led by two kings, Louis VII of France and Conrad III of Germany, and preached by St. Bernard himself. It failed miserably. Most of the Crusaders were killed along the way. Those who made it to Jerusalem only made things worse by attacking Muslim Damascus, which formerly had been a strong ally of the Christians. In the wake of such a disaster, Christians across Europe were forced to accept not only the continued growth of Muslim power but the certainty that God was punishing the West for its sins. Lay piety movements sprouted up throughout Europe, all rooted in the desire to purify Christian society so that it might be worthy of victory in the East.

Crusading in the late twelfth century, therefore, became a total war effort. Every person, no matter how weak or poor, was called to help. Warriors were asked to sacrifice their wealth and, if need be, their lives for the defense of the Christian East. On the home front, all Christians were called to support the Crusades through prayer, fasting, and alms. Yet still the Muslims grew in strength. Saladin, the great unifier, had forged the Muslim Near East into a single entity, all the while preaching jihad against the Christians. In 1187 at the Battle of Hattin, his forces wiped out the combined armies of the Christian Kingdom of Jerusalem and captured the precious relic of the True Cross. Defenseless, the Christian cities began surrendering one by one, culminating in the surrender of Jerusalem on October 2. Only a tiny handful of ports held out.
