But facts about the Crusades are much more complicated than that. The Crusades weren’t just one movement, but dozens, led by hundreds of knights, kings, and dukes, and not always bent on capturing Jerusalem. They were incredibly brave fighters, but also bloodthirsty killers. They tried to free Jerusalem, but also sacked a number of ancient cities, destroying priceless artifacts and culture.
The history of the Crusades is complicated, but also full of interesting information. Here are some of the most fascinating Crusades facts about this difficult period of time.
The Crusades Lasted Two Centuries
They’re Inexorabily Linked with the Catholic Church
There Were Nine “Official” Crusades
There Were Also Dozens of Smaller Crusades
Crusading Knights Had Very Complex Rules for Combat
Knights of the Middle Ages operated under a complex series of religious rules for combat, instituted to control what was perceived as an almost unquenchable lust for violence and conquest. Under the Peace of God, church property was off limits for destruction, as were women, children, the elderly, and other non-combatants.
The Truce of God, added to the Peace of God in the 11th century, limited the days that combat could be initiated (Lent, Advent, Fridays, and Saturdays were no-nos), ultimately making only 80 days available for fighting. The Peace and Truce of God is generally seen as a failure, but it did help reestablish order in conflict-ravaged western Europe, and was a critical precursor to the Crusades.
The Call for the First Crusade Came Straight from the Top
In 1095, Seljuk Turks had such a tight grip on Jerusalem that Christians were barred from entering. When the Turks threatened to invade the Byzantine Empire, Emperor Alexius I appealed to Pope Urban II for military assistance. Urban II promptly called the Council of Clermont in November 1095, ending it with a rousing speech. In front of hundreds of clerics and nobles, Urban denounced Islam, excoriated its anti-Christian acts (most of which likely didn’t happen), and called on the rich and poor to unite in a religious war against them.
With a battle cry of “God wills it!” the Crusades were born.
The First Crusade Went Way Better Than Anyone Expected
Urban II’s call to arms was a huge success. Tens of thousands of people attempted to join the growing Crusader armies, but most were peasants with no combat training. The exact numbers are unknown, but it’s generally agreed upon that about 35,000 soldiers under the command of four different princes left Europe for the Byzantine capitol Constantinople in August 1096.
After that, they crossed into Asia Minor, laid siege to several major cities, including Nicaea and Antioch, then finally reached Jerusalem in 1099. Only a third of the initial 35,000 strong force was left, forcing an attack on multiple sides of the walled city. Jerusalem was taken when the defenders abandoned the walls, and the Crusaders entered the city. They took the Church of the Holy Sepulcher, established the Kingdom of Jerusalem, and slaughtered most of the remaining Muslim and Jewish defenders. The First Crusade had been a stunning success.
It Also Wasn’t Actually the First Crusade
The Victorius Crusaders Formed Their Own Countries
Beyond the Kingdom of Jerusalem, formed in 1099 after the holy city fell, several other “Crusader states” were created in the wake of conquests in the Middle East. These were territories founded by Crusaders who went to the Holy Land and didn’t want to go back, instead staying to convert infidels and demonstrate Church power. For example, the County of Edessa, in modern day Turkey, was formed in 1098 and lasted about 50 years, when its sacking prompted the Second Crusade to form. The Principality of Antioch (modern day Turkey and Syria), also formed in the wake of the First Crusade, and was retaken in 1268 by the Sultan of Egypt.
A number of other Crusader States came into being in the next 200 years, almost all of which had been taken by other kingdoms by the end of the 13th Century.
There Was a Crusade of People Left Out of the First Crusade
Pope Urban II Didn’t Live to See the Results of His Fiery Speech
The Second Crusade Was a Humiliating Failure
In 1144, the Seljuk Turk general Zangi, governor of Mosul, captured the Crusader State of Edessa. The next year, Pope Eugenius III issued a call to arms similar to Urban II’s bull of 1098. King Louis VII of France answered the call for the Second Crusade, as did King Conrad III of Germany, who was spurred on by the mystic monk Bernard of Clairvaux. They raised a massive army and marched to Constantinople, where they planned to retake Edessa and reinforce Jerusalem.
Instead, the two kings barely communicated and the attack was poorly planned. Their combined force was eventually beaten at Damascus – never having actually tried to liberate Edessa.
Jerusalem Was Retaken Between the Second and Third Crusades
The Third Crusade Was Launched by Richard the Lionheart
When news reached Europe that Saladin had taken Jerusalem, another call for Crusade went out. King Henry II of England and Phillip II of France began to organize a new army, but Henry died soon after, and Richard I took his place. Along with the elderly emperor of the Holy Roman Empire, Fredrick Barbarossa, the kings planned the attempt to retake Jerusalem.
Typical of the disorganization of the Crusades, Frederick couldn’t wait for the other armies, and launched his crusade on his own. He had some success at first, then drowned crossing a river. Most of his army turned around and went back to Germany before the French and English armies even arrived in the Middle East. A series of battles and massacres ensued, and the Third Crusade ended with Saladin beaten at Jaffa. A truce was reached, with Jerusalem staying under Muslim control.
The Fourth Crusade Split the Catholic Church in Two
1202 saw the Fourth Crusade called. Crusaders from Venice, the Holy Roman Empire, and the Kingdom of France laid siege to Constantinople. In 1204, they brutally sacked the city, going on a vicious spree of killing, looting, and burning. Pope Innocent III, who had initially called for the Fourth Crusade, rebuked the Crusaders – but still accepted the loot they brought back to Rome.
Only a few knights actually bothered going on to the Holy Land, and the ancient Greek treasures of Constantinople were either destroyed or taken. The conflict between Greek and Roman Catholic Christians was so bloody that it permanently cemented the schism between Eastern Orthodox Christianity and the Vatican. It still hasn’t healed.
The Fifth Crusade Ended with a Bit of Scammery
Pope Innocent III and his successor called for yet another Crusade to take Jerusalem back. Plans were duly made, and in 1213, a coalition of German, Hungarian, Austrian, French, and Holy Roman Empire knights left for the Holy Land. They attacked Egypt as a precursor to taking Jerusalem, but were crushed by forces led by Al-Kamil, the nephew of Saladin.
Al-Kamil agreed to a truce with the Crusaders, and agreed to give them back a piece of the True Cross, taken at the Battle of Hattin. Al-Kamil didn’t actually have it, and used the True Cross as a bargaining chip.
The Sixth Crusade Actually Worked… For a While
Seven years after the Fifth Crusade failed, the Sixth Crusade was launched. Unlike most of the others, this one involved very little combat. Instead, Holy Roman Emperor Frederick II negotiated with Al-Kamil to regain control over certain parts of Jerusalem. Christian control was restored to much of what’s now Israel – though Muslims stayed in possession of the Temple Mount, the al-Aqsa mosque, and the Domeof the Rock – all areas that are still in Muslim custody.
The treaty was cemented in February 1229, and Frederick entered the city a month later.
The Seventh Crusade Was a Disaster
Christian control of Jerusalem didn’t last long. In 1244, the remnants of the Khwarezmian Empire, which had been thrown out of Iran by the Mongols, were invited by Al-Kamil’s successors to invade the holy city, which was weakly defended. The Kwarezmians completely razed Jerusalem, leaving it in ruins. Europe was too preoccupied by other wars and conflicts with the Papacy to take much notice.
Only King Louis IX of France was outraged enough to mount a Crusade in response, but his weak effort was crushed with tens of thousands of deaths.
The Crusade Chronology Gets Pretty Complicated After That
Louis IX of France was humiliated by the defeated of the Seventh Crusade, and called for another. Some historians call this subsequent effort the Eighth Crusade, while others consider it an extension of the Seventh. Making things even more confusing is that the Ninth Crusade, which followed a few years later, is sometimes considered part of the Eighth.
Whatever the nomenclature, the Eighth Crusade was as much a disaster as the Seventh. Louis IX raised another army, and landed in Tunis in July 1270. Dysentery ravaged the Crusaders, killing Louis IX, and with their army under siege, the Crusaders went back to France.
The Mongols Got Involved in the Whole Thing
When Jerusalem fell to the Kwarezhmians in 1244, many European Christians looked outside the box for allies in fighting the Muslim menace. Around the same time, in 1242, the Mongol threat to western Europe ended with the death of Ogedai Khan, the son and successor of Genghis. The lull in conflict in the east led to the proposal of a Franco-Mongol alliance to take Jerusalem back from an empire that was already an enemy of the Mongols.
Pope Innocent IV sent an envoy, the monk John of Plano Carpini, to the Mongol capitol of Karakorum, with an incomprehensible letter asking for peace and assistance dealing with Islam. But the new Khan, Guyuk, responded with a demand that the Pope submit to Mongol rule. The alliance never came to fruition, and the Mongols would eventually go to war with Islam, laying waste to Baghdad.
The Ninth Crusade Petered Out and Ended the Crusades
The Crusades Drew in Many Luminaries of the Time
Women Played a Major Role in the Crusades
Women participated in every aspect of the Crusades, shattering a number of old gender restrictions. As land-owning men went off to fight, their wives took control of their estates. Papal protection was given to these women, as not doing so would discourage men from joining. Many women also went along with the Crusading parties as camp followers and nurses, including prominent noble women. Muslim chroniclers write of women fighting ferociously alongside men, though these accounts are disputed.
Finally, the death of nobles sometimes meant land holdings and possessions were left to wives, disrupting much of the culture of inheritance prominent in Europe at the time.
The Infamous Children’s Crusade Might Not Have Ever Happened
The Children’s Crusade is one of the most controversial aspects of studying this period of the Middle Ages. Traditional accounts say that in or around 1212, a French or German boy began preaching that he’d been called on by God to liberate the Holy Land. He gathered a huge band of children, and together they marched toward the Mediterranean Sea, expecting it to part. When it didn’t, the children either drowned or were captured and sold into slavery.
Modern scholarship disputes almost every aspect of this story. While the Crusade is mentioned in dozens of period sources, the stories are contradictory and embellished. It’s not clear whether there was actually an organized crusade, or if there was, if it was made up of children. Scholars generally agree that separate French and German bands of mostly children, led by charismatic boy preachers, set out for the holy land and met disaster – but the details will never be known.
The Crusades Had an Enormous Impact on Europe
The cost in lives of the Crusades can’t be known with certainty, but it’s anywhere between two million and six million deaths over 200 years. They brought the Papacy immense wealth and power, made fortunes for shipbuilders and merchants, and introduced Europe to the opulence of Oriental trade. They also swept away much of the remnants of feudalism, cross-pollinated a number of European cultural traits around the world, and obliterated many prominent noble family lines.
European expansion that started in the Crusades continued with the sending of ships to the New World, and the Greek and Roman works brought back to Europe were among the catalysts of the Renaissance. Mathematical, architectural, and historic knowledge exploded in Europe as a result of the Crusades – all of which would make the foundation of the modern world.
The Crusades Were Incredibly Anti-Semitic
The Crusades Are Still Talked About – Often Incorrectly
Even now, both Western and Muslim pundits come back to the Crusades when they need a shorthand for “atrocities.” Western conservatives often see the Crusades as an attempt to liberate the Holy Land from murderous heathens, and liberals point out that mass killing was carried out on all sides. When President Obama mentioned Christian atrocities carried out during the Crusades, he was accused of belittling Christianity – despite the fact that it’s an indisputable fact that Christian Crusaders did in fact kill countless numbers of Jews, Muslims, Byzantine Greeks, and others.
