Events

By place

Seventh Crusade

• May 13 – King Louis IX (the Saint) assembles a Crusader fleet of 120 transports and embarks an army (some 15,000 men) at Limassol. Unfortunately, a storm scatters the ships a few days later. On May 30, Louis sets sail to Egypt – only a quarter of his forces sails with him, the others make their way independently to the Egyptian coast. Finally, the royal squadron arrives off Damietta on June 4 aboard Louis' flagship the Montjoie. The king's advisers urges a delay until the rest of his transports arrive before attempting to disembark, but Louis refuses.^[1]
• June 5 – Siege of Damietta: Louis IX lands with a Crusader force and captures Damietta, after a fierce battle at the edge of the sea. The onslaught of the knights of France and those of Outremer under John of Ibelin, force the Ayyubids back with heavy losses. At nightfall, Fakhr ad-Din withdraws his army over a bridge of boats to Damietta. Finding the population there in panic and the garrison wavering, Fakhr ad-Din decides to evacuate the city. On June 6, Louis marches triumphantly over the bridge into Damietta and builds a camp to attack Cairo.^[2]
• November 20 – Louis IX sets out (against the advice of his nobles) with a Crusader force from Damietta, along the southern road to Mansourah. A garrison is left to guard the city – where Queen Margaret of Provence and Patriarch Robert of Nantes remain. The Crusaders make slow progress along the Nile, carrying a number of supplies and equipment. After 32 days, Louis orders to make camp opposite the Ayyubid camp near Mansourah, protected by a branch of the river and fortifications. Both camps use their catapults to bombard each other.^[3]
• December – Louis IX consolidates his forces at Mansourah. After the death of Sultan As-Salih Ayyub, Fakhr ad-Din effectively becomes the ruler of Egypt. He takes command of the city's defense and his cavalry harasses the Crusaders but none of these skirmishes is successful in holding up the Crusader's advance. Meanwhile, Louis orders the construction of a dyke at Mansourah, although the Crusaders build covered galleries to protect the workmen, the Egyptian bombardment (particularly Greek fire), is so formidable that the work is halted.^[4]

Europe

• February 16 – Louis IX sends Andrew of Longjumeau on a diplomatic mission to meet the "Great Khan" of the Mongol Empire. He carries letters from Louis and the Papal States, and rich presents, including a chapel-tent lined with scarlet cloth and embroidered with sacred pictures. From Cyprus he goes to the port of Antioch in Syria and travels for a year to the khan's court at Karakorum.^[5]
• May – Nicaean–Latin Wars: Latin forces led by William of Villehardouin, arrive on the island of Rhodes on their way to join the Seventh Crusade. This causes the Nicaeans to raise the siege of Rhodes. William concludes an agreement with the Genoese and leaves behind some 100 knights before departing for the Holy Land.^[6]
• May 26 – Battle of Fossalta: King Enzo of Sardinia, an illegitimate son of Emperor Frederick II, is captured and imprisoned by Lombard forces, in a clash between the Guelphs and Ghibellines. Enzo is put in golden chains and paraded around Bologna on a horse. He becomes a prisoner in a palace, named Palazzo Re Enzo.
• July 6 – King Alexander II dies of a fever at the island of Kerrera in the Inner Hebrides. He is succeeded by his 7-year-old son, Alexander III, who is crowned as ruler of Scotland at Scone, on July 13. Alexander's minority causes a struggle for control of affairs between Walter Comyn and Alan Durward, Justiciar of Scotia.
• Summer – Second Swedish Crusade: A Swedish expedition led by Birger Jarl subjugates the province of Tavastia – securing Swedish power in Finland. As a part of the Treaty of Lödöse Birger marries off his 11-year-old daughter Rikissa to Haakon the Young, ruler and eldest son of King Haakon IV (the Old) of Norway.
• King Afonso III (the Boulonnais) recaptures Faro and Silves in the Algarve from the Almohads, thus ending the Portuguese Reconquista. The Almohads lose possession of Alicante in Al-Andalus (modern Spain).^[7]
• August 15 – First Battle of Athenry: Gaelic forces of Connacht besiege Athenry Castle in County Galway in Ireland. But are repelled by the Normans under Jordan de Exeter, Sheriff of Connacht.
• Winter – William of Villehardouin tours the Peloponnese and selects sites for new fortifications such as Grand Magne and Leuktron. At Mystras (ancient Sparta), he builds a fortress and a palace.
