## Events
### Fifth Crusade

* Summer – Various groups of French knights reach the Italian ports. King Andrew II of Hungary arrives with his army in Split, in Dalmatia. He is joined by German forces, led by Duke Leopold VI (the Glorious). At the end of July, Pope Honorius III orders the crusaders assembled in Italy and Sicily to proceed to Cyprus, but there is no transport provided by the Italian city-states, Venice, Genoa and Pisa.
* September: Leopold VI finds some ships in Split, that bring him and a small force to Acre. Andrew follows him about a fortnight later; in Split, he receives only two ships. The rest of Andrew's army is left behind. Meanwhile, King Hugh I of Cyprus lands at Acre, with troops to support the Crusade.
* November – The Crusader army (some 15,000 men) under Andrew II sets out from Acre, and marches up the Plain of Esdraelon. Sultan Al-Adil I, on hearing that the crusaders are assembling, sends some Muslim troops to Palestine, to halt their advance. The crusaders move towards Beisan, while Al-Adil waits at Ajloun Castle, ready to intercept any attack on Damascus. He sends his son, Al-Mu'azzam, to cover Jerusalem. On November 10, Andrew's well-mounted army defeats Al-Adil at Bethsaida, on the Jordan River. Beisan is occupied and sacked; the Muslims retreat to their fortresses and towns.
* December – King John I of Jerusalem leads an expedition into Lebanon. On December 3, he undertakes fruitless assaults on Muslim fortresses and on Mount Tabor. Meanwhile, the Crusader army under Andrew II wanders across the Jordan Valley and up the eastern shore of the Sea of Galilee. During the occupation, Andrew spends his time collecting alleged relics. By the end of December, supplies run out, and the crusaders retreat to Acre.

### Other events by place
#### Europe

* Spring – First Barons' War: English forces of King Henry III besiege the French-controlled Mountsorrel Castle in Leicestershire. Prince Louis sends reinforcements (some 20,000 men) to assist the Barons in the castle. The English army lifts the siege and withdraws to Nottingham. Louis makes the mistake of moving the French forces to Lincoln Castle – where the English garrison holds out against previous attacks. Meanwhile, Henry's forces return to Mountsorrel Castle. This time Louis fails to arrive in time to prevent the razing to the ground of the castle.
* April 9 – Peter II of Courtenay is crowned emperor of the Latin Empire of Constantinople at Rome, by Pope Honorius III. Shortly after his coronation, Peter borrows some ships from the Venetians, promising in return to conquer Durazzo for them. He fails in this enterprise and seeks to make his way to Constantinople by land. On the journey, he is seized by troops of Theodore Komnenos Doukas, despot of Epirus, and is put in prison.
* May 20 – Battle of Lincoln: Henry III's forces led by William Marshal, 1st Earl of Pembroke defeat the French army of Prince Louis and the rebel barons who are besieging Lincoln Castle. During the battle, Thomas, Comte du Perche is killed and Louis is expelled from his base in the southeast of England. The looting that takes place afterward is known as the "Lincoln Fair". The citizens of Lincoln are loyal to Louis so Henry's forces sack the city. To the south, inhabitants of towns between Lincoln and London ambush and kill many of the French soldiers.
* June 6 – The 13-year-old King Henry I of Castile dies from the fall of a roof tile in Palencia, an event which his regent, Álvaro Núñez de Lara, attempts to conceal. He is succeeded by his sister Berengaria, who renounces the throne in favour of her son Ferdinand III, on August 31. The young king begins his reign (supported by his mother as adviser and regent) by a war against his father, King Alfonso IX of León, and the Castilian nobles.
* June – The 13-year-old Haakon IV becomes king of Norway, following the death of Inge II (Bårdsson) – this largely ends the civil war era in Norway. During his minority, Earl Skule Bårdsson becomes Haakon's regent.
* August 24 – Battle of Sandwich: An English fleet under Hubert de Burgh defeats the French armada (10 large ships and 70 supply ships) in the English Channel, near Sandwich. The French fleet is commanded by Eustace the Monk, a mercenary and pirate, who fights for both the French and English when it suits his needs. The French fleet is bringing more men and supplies to assist Prince Louis, in his quest to take the English throne. The English capture Eustace's flagship, and Eustace himself is (while offering 10,000 marks for ransom) beheaded.
* September 12 – Treaty of Kingston: The First Baron's War ends. After the defeat of the French fleet, Prince Louis is without hope of taking the English throne. William Marshal blockades London from the sea and land. At Lambeth Louis accepts peace terms. He waives his claim for the throne and promises to restore Normandy to Henry III but does not. The French and Scots are to leave England, and an amnesty is granted to the rebels.
* September 21 – Livonian Crusade: The Livonian Brothers of the Sword and allied Livs and Letts defeat the Estonian army in the Battle of St. Matthew's Day, and kill their leader Lembitu.
