The Crusades were two centuries of wars in which the Christian rulers of Europe tried to take and hold Jerusalem and the land around it, and the Muslim rulers of Egypt and Syria tried to take it back. There were nine of them by the usual count. The first took Jerusalem in 1099 with a massacre; the third failed to retake it from Saladin and made a treaty instead; the fourth never reached the Holy Land and sacked Constantinople; and the last ended with a thousand men, a truce and an assassin. This timeline runs from the split of the Church in 1054 to the last outposts falling in 1303, and one of its eight chapters has no dates in it at all, because it is about what taking the cross actually meant.

Clermont, Jerusalem, Constantinople and Acre.
Forty years before anyone took the cross, the Church split into a Catholic west and an Orthodox east, and the Turks destroyed the Byzantine army at Manzikert and took most of Asia Minor. The emperor in Constantinople, short of soldiers, wrote to a pope his own church had excommunicated and asked for mercenaries. What Urban II offered at Clermont on November 27th, 1095 was something else: a war in which fighting was a way to salvation. The response was larger than he expected, and he never learned how it ended.

On July 16th, 1054, a cardinal sent from Rome laid a bull of excommunication on the altar of the Hagia Sophia in Constantinople. The patriarch there answered in kind. Historians use that date for the split between the Roman Catholic Church in the west and the Eastern Orthodox Church in the east.
LEARN MORESHOW LESSwhy it matters · key numbersRELIGIONForty-one years later a pope would send western armies to help the eastern emperor. They were helping a church they had just excommunicated, and that awkwardness runs under the whole story, all the way to a crusader army sacking Constantinople in 1204.

In 1071 the Seljuk Turks defeated a Byzantine army at Manzikert in eastern Anatolia and captured the emperor. Much of Asia Minor, the empire's main source of soldiers and grain, was opened to Turkish settlement.

On November 27th, 1095, at the Council of Clermont in France, Pope Urban II preached a sermon calling on the knights of Europe to march east, help the Christians of the empire and free Jerusalem from Muslim control.

The poor went first and were slaughtered at Civetot. Then four armies of princes, about 35,000 men with no single commander, crossed Anatolia, starved for eight months outside Antioch, and took Jerusalem on July 15th, 1099, killing most of the people in it. It is the only crusade that did what it set out to do, and it did it against a Muslim world too divided to answer. Within eighteen months there were four Crusader States and a king in Jerusalem, and the next two centuries were spent trying to keep them.

Before the official armies had left, a preacher called Peter the Hermit led thousands of poor pilgrims, with few knights and little food, east through Germany and Hungary. The People's Crusade ran from April to October of 1096.

The four main armies, roughly 35,000 crusaders and 5,000 cavalry by historians' estimates, reached the Byzantine capital between late 1096 and early 1097. Alexius made each leader swear to hand back any former imperial land they captured.

The crusaders reached Antioch, one of the great walled cities of the east, in October of 1097 and settled in to besiege it. The siege lasted until June of 1098, through a winter in which the besiegers starved almost as badly as the besieged.

Godfrey's brother Baldwin left the main army, marched east, and in February of 1098 was adopted as heir by the Armenian ruler of Edessa. Within weeks he ruled the city. The County of Edessa was the first of the four Crusader States.

This chapter has no dates in it. Seven of the articles behind this timeline are about what going on crusade meant rather than when anything happened: what the Holy Land was and why Jerusalem above all, why a European would sew a cross on his cloak and walk 2,000 miles, what the vow committed him to, what a knight was, how a walled city was taken, and what the four small states the crusaders founded actually were. It sits here, after the First Crusade, because that is when all of it became real.

The Holy Land is the territory of the Bible: Jerusalem, Bethlehem, Nazareth and the country between them. It was holy to Christians, to Jews and to Muslims, all of whom had claims on it older than any crusade.
LEARN MORESHOW LESSwhy it mattersLIFEThe crusaders were not fighting over empty ground. Three faiths held the same places sacred, which is why control of them mattered so far beyond their size.

For Christians, Jerusalem was where Jesus was crucified and buried. For Muslims it was the place from which Muhammad ascended to heaven, the third holiest city in Islam. For Jews it was the site of the Temple.
LEARN MORESHOW LESSwhy it mattersLIFEA city that three religions could not give up is a city nobody could hold in peace. The Crusades were a two-hundred-year argument over one square mile.

Some went for their faith and the promise that their sins would be forgiven. Some went for land, because younger sons of nobles inherited nothing. Some went for loot, for adventure, or because their lord went and they had to follow.
LEARN MORESHOW LESSwhy it matters · a debateLIFEMixed motives are not a modern discovery. The chroniclers of the time complained about crusaders who came for plunder, and the crusaders who came for God did most of the killing.
Did the crusaders go for God or for gain?
For God. Going was ruinously expensive, most who went came home poorer or did not come home, and the promise of remitted sins was the one thing the pope actually offered.
For gain. Younger sons with no land, merchants from Genoa and Venice, and kings who needed a war abroad all found what they were looking for in the east.

A crusader made a vow before God, sewed a cloth cross onto his clothing, and set out on a journey that could take a year each way. He paid his own costs, which for a knight could mean selling or mortgaging his land.
LEARN MORESHOW LESSwhy it mattersLIFETaking the cross was a religious act with a legal weight: the Church protected a crusader's property while he was away and punished those who failed to go. It was not a decision a man could take back.

A knight was a mounted, armored fighter trained from boyhood. The idea of the Christian knight as a defender of the faith was one of the main reasons so many of them answered the call.
LEARN MORESHOW LESSwhy it mattersLIFEThe Church spent a century trying to turn knights from a menace into a force it could direct. The crusade was the answer: a war in which knightly violence was holy.

Antioch, Jerusalem, Acre, Damietta, Constantinople: every decisive moment of the Crusades was a siege. Crusaders built towers, rams and stone-throwing engines on the spot, from whatever timber they could find.

The Germans were destroyed at Dorylaeum before reaching Syria; the French arrived weak, quarrelled at Antioch, and the two kings then attacked Damascus, a friendly Muslim city, for five days and went home. The only lasting conquest was Lisbon, made by accident on the way. A queen of France rode the whole way and her marriage did not survive it.

Why did the Second Crusade fail?
Bad luck and bad geography. The German army was destroyed in Anatolia before it had done anything, and the French arrived too weak to attempt Edessa.
Bad choices. Two kings who did not trust each other or the emperor chose to attack a friendly city rather than the one they had come to recover, and gave up after five days.
A Kurdish soldier who took command in Egypt at thirty-one spent seventeen years uniting Egypt and Syria, mostly by fighting other Muslims, and then destroyed the entire army of the Kingdom of Jerusalem in one day at Hattin. Jerusalem surrendered on terms, with no massacre, and the contrast with 1099 was the point. Europe's three most powerful rulers answered: an emperor who drowned in a river, a king of France who went home after Acre, and Richard of England, who beat Saladin at Arsuf, came within sight of Jerusalem, turned back, and made a treaty instead.

A crusade called against Egypt contracted Venice for a fleet three times larger than the army that turned up. To pay the debt it took a Catholic city for Venice and was excommunicated. To pay the rest it agreed to put a claimant on the Byzantine throne, sailed to Constantinople, put him there, and when he could not pay either, stormed the largest Christian city in the world on April 13th, 1204 and looted it for three days. It never saw the Holy Land. The empire it broke recovered its capital in 1261 and never its strength.
In 1201 the crusade's leaders contracted with Venice, the greatest naval power in the Mediterranean, to build and crew a fleet for 33,500 crusaders. The price was 85,000 marks, payable before sailing.
LEARN MORESHOW LESSwhy it matters · key numbersPOLITICSThe number was a guess and it was far too high. When only about a third of the expected crusaders turned up, the debt to Venice decided where the crusade went.
Unable to pay, the crusaders accepted Venice's offer to defer the debt in exchange for helping recapture Zara, a Christian city on the Adriatic that had rebelled against Venetian rule. They took it in November of 1202. The pope excommunicated the whole army.
LEARN MORESHOW LESSwhy it mattersWARA crusade called against Muslims began by sacking a Catholic city for a creditor. Once that line was crossed, Constantinople was only a larger version of the same decision.
A claimant to the Byzantine throne offered the crusaders money and soldiers if they would put him on it. The fleet sailed to Constantinople instead of Egypt and arrived on June 23rd, 1203, outside a city of about 500,000 people defended by 15,000 soldiers.
LEARN MORESHOW LESSwhy it matters · key numbersPOLITICSHistorians still argue over whether Venice steered the crusade there on purpose. Either way, an army sent to fight Islam was now outside the largest Christian city in the world.

The crusaders attacked from July 11th, 1203. On August 1st the emperor fled and the crusaders' candidate was crowned, but he could not pay what he had promised, and the city turned against him and them.
LEARN MORESHOW LESSwhy it mattersSIEGEThe crusaders had done what they came for and got nothing. Over the winter the deal fell apart, and in the spring they attacked the city for themselves.

After fighting through the spring, the crusaders broke into Constantinople on April 13th, 1204 and sacked it for three days: churches stripped, the Hagia Sophia looted, and treasures that had survived since antiquity carried off or melted down. The empire was carved into crusader and Venetian states.
LEARN MORESHOW LESSwhy it matters · a debateWARThe Fourth Crusade never reached the Holy Land. It destroyed the Christian empire that had asked for the First Crusade, deepened the schism of 1054 beyond repair, and left Constantinople too weak to survive the Turks two centuries later.
Was the sack of Constantinople an accident?
Yes. A chain of debts and broken promises took a crusade somewhere no one had planned to go, and each step looked reasonable to the people taking it.
No. Venice had every reason to want its rival broken, the crusade's leaders had every reason to want a rich city, and the 'accident' happened to serve both perfectly.
The planners now reasoned that Jerusalem could not be held while Egypt was hostile. The Fifth Crusade took Damietta after sixteen months, was offered Jerusalem in exchange for leaving, refused, marched on Cairo and surrendered in the flooded delta. An excommunicated emperor then got Jerusalem back by treaty without a battle, and nobody rebuilt the walls, so it was lost again in 1244. Louis IX of France, the best-prepared crusader since Barbarossa, took Damietta in a day, marched on Cairo, and was captured in the same mud thirty years after the last army had been.
In April of 1213 Innocent III called for another crusade, this one planned and financed by the Church from the start so that no one could divert it. The target was Egypt again.
LEARN MORESHOW LESSwhy it mattersRELIGIONThe lesson of the Fourth Crusade was that the pope had to own the whole thing. He did, and it changed the outcome very little.

Innocent III died on July 16th, 1216, a year before the crusade he had organized set out. His successor, Honorius III, saw it through.
LEARN MORESHOW LESSwhy it mattersRELIGIONTwo crusades called, neither of them seen to its end. The most powerful pope of the age never saw a crusader army reach the Holy Land.
The Fifth Crusade began in July of 1217 when King Andrew II of Hungary left for the Holy Land. As many as 30,000 crusaders took part in all. Andrew fell ill early in 1218 and went home.

Was the Sixth Crusade a success?
Yes. It recovered Jerusalem, Bethlehem and Nazareth without a single battle, which no crusade since the first had managed by any means.
No. The treaty ran out, the city was indefensible without its walls, and it was lost again fifteen years later. Frederick gained a title and Jerusalem gained nothing lasting.
The treaty expired and nobody had rebuilt the walls. In 1244 Khwarazmian horsemen, allies of the Egyptian sultan, stormed Jerusalem and sacked it. The city was never in Christian hands again.
LEARN MORESHOW LESSwhy it mattersWARFifteen years after Frederick's treaty, Jerusalem was gone for good. It was the news that sent a king of France to Egypt.

Louis IX of France, who had vowed to crusade during a near-fatal illness, sailed from Aigues-Mortes in 1248 with over 15,000 men, 3,000 of them knights, in thirty-six ships. He aimed at Egypt.

Louis IX took the cross a second time and went to Tunis, 1,500 miles from Jerusalem, for reasons historians still argue about, and died of dysentery in his camp within six weeks. Edward of England, sailing to join him, went on to Acre alone with a thousand men, helped it survive one attack, made a truce and survived an assassin. He was the last western prince to fight in the Holy Land. In 1291 the Mamluks took Acre in six weeks and no army came. Popes went on calling crusades for two more centuries; nobody answered.
On March 24th, 1267, Louis IX announced that he would go on crusade again. His nobles were unenthusiastic, and the target this time was not Egypt or the Holy Land but Tunis, in North Africa.
LEARN MORESHOW LESSwhy it matters · 1 key figureRELIGIONWhy Tunis has puzzled historians ever since. Louis may have believed its ruler could be converted; his brother, the king of Sicily, had interests there. Either way it was 1,500 miles from Jerusalem.

Why did the Crusader States fall?
Because Europe stopped sending armies. After Louis IX died, no king went east again, and Acre was left to a garrison and a handful of military orders.
Because they could never have lasted. Four small states of western settlers on a hostile coast, dependent on a sea route and on Muslim disunity, were finished the moment Saladin and then the Mamluks united Egypt and Syria.
