## Events
### By place
#### Byzantine Empire

* July 31 – John Komnenos the Fat, a Byzantine aristocrat, attempts to usurp the imperial throne; he is proclaimed emperor and crowned by Patriarch John X Kamateros, at Constantinople. Meanwhile, Emperor Alexios III Angelos, who resides in the Palace of Blachernae, dispatches a small force under Alexios Palaiologos, Alexios' son-in-law, who is regarded as his heir-apparent. With support of the Varangian Guard, John is overthrown and decapitated by the end of the day. His head is displayed at the Forum of Constantine, while John's supporters are captured and tortured to extract the names of all the conspirators.
* Autumn – Prince Alexios Angelos, son of the deposed, blinded and imprisoned late Emperor Isaac II Angelos, escapes from Constantinople. He makes his way to Sicily and then Rome where he is turned away by Pope Innocent III. Next, Alexios travels to the court of his brother-in-law, Philip of Swabia, the King of Germany, who receives him well.

#### Europe

* Spring – A treaty is signed between the Crusade leaders and Venice. Doge Enrico Dandolo agrees to manufacture a fleet capable of transporting the Crusader army to the Levant, and to provide provisions for 33,500 men and 4,500 horses, for the price of 85,000 silver marks while Venice will also take half of whatever the expedition conquers. As part of this deal the Venetians will provide – at their own expense – sufficient ships to carry the Crusader forces, plus 50 galleys to defend it.
* May 24 – Count Theobald III of Champagne suddenly dies and is replaced by Boniface I, marquis of Montferrat, as leader of the Fourth Crusade. He travels to France, where he meets his chief colleagues at Soissons.
* Battle of Stellau: Count Adolf III of Holstein is defeated by the Danish army under King Canute VI. Adolf retreats with his forces to Hamburg, where he is besieged and later captured by Duke Valdemar of Schleswig.
* Northern Crusades: The town of Riga is chartered as a city by Albert of Buxhoeveden, bishop of Livonia, who has landed on the site with some 1,500 Crusaders earlier in the year.

#### British Isles

* July 11 – Llywelyn the Great pays homage to John, King of England after Llywelyn has added Eifionydd and Llŷn to his kingdom of Gwynedd in north Wales.
* King John puts an embargo on wheat exported to Flanders, in an attempt to force an allegiance between the states. He also puts a levy of a fifteenth on the value of cargo exported to France and disallows the export of wool to France without a special license. The levies are enforced in each port by at least six men – including one churchman and one knight. John affirms that judgments made by the court of Westminster are as valid as those made "before the king himself or his chief justice".
