## Events
### By place
#### England

* July 10 – The Great Fire: The most severe of several early fires of London burns most of the city to the ground; over 3,000 people die, many of them by drowning in the River Thames. According to a contemporary account: "An awful fire broke out on the Southwark side of London Bridge; while it was raging, a fire broke out at the other end also and so hemmed in the numerous crowds who had assembled to help the distressed. The sufferers, to avoid the flames, threw themselves over the bridge into boats and barges; but many of these sunk, the people crowding into them.".
* John, King of England, impounds the revenue of all prelates appointed by bishops, who have deserted him at his excommunication. He remains on good terms, however, with churchmen who stood by him, including Abbot Sampson, who this year bequeaths John his jewels.

#### Europe

* Spring – After the fall of Argos the Crusaders complete their conquest of the Morea in southern Greece. The city, along with Nauplia, is given to Othon de la Roche, a Burgundian nobleman, as a fief, along with an income of 400 hyperpyron from Corinth. Meanwhile, the Venetians conquer Crete and evict Henry, Count of Malta ("Enrico Pescatore"), a Genoese adventurer and pirate, active in the Mediterranean.
* July 16 – Battle of Las Navas de Tolosa: The Christian forces of King Alfonso VIII of Castile ("the Noble") decisively defeat the Almohad army (some 30,000 men) led by Caliph Muhammad al-Nasir. The victory gives a further impulse to the Reconquista but this leaves the Kingdom of Castile in a difficult financial position, as numerous soldiers have to be paid by the treasury.
* The Children's Crusade is organized. There are probably two separate movements of young people, both led by shepherd boys, neither of which embark for the Holy Land – but both of which suffer considerable hardship.
** Early Spring – Nicholas leads a group from the Rhineland and crosses the alps into Italy. In August, he arrives with some 7,000 children in Genoa. Nicholas travels to the Papal States where he meets Pope Innocent III.

In the region of northern Germany, the center of Guelph power, his rival Otto IV continues to hold the imperial power despite his excommunication.
* The Teutonic Order builds Bran Castle in the Burzenland (modern Romania) as a fortified position at the entrance of a mountain pass through which traders can travel. The Teutonic Knights build another five castles, some of them made of stone.
