Events

By place

Byzantine Empire

Battle of Adrianople: Byzantine forces under Emperor Theodore II Laskaris defeat the invading Bulgarians near Edirne (Adrianople). The young and inexperienced Tsar Michael II Asen is caught by surprise and the Bulgarians suffer heavy losses. Michael is wounded during his hasty retreat through the forest.

Europe

May 21 – King Conrad IV, son of the late Emperor Frederick II, dies of malaria at Lavello (southern Italy). With Conrad's death a interregnum begins, during which no ruler manages to gain undisputed control of Germany. The 22-year-old Manfred, half-brother of Conrad, refuses to surrender Sicily to Pope Innocent IV and accepts the regency on behalf of Conrad's 2-year-old son Conradin ("the Younger").
November 2 – German forces under Manfred start an anti-papal revolt against Innocent IV and seize Lucera in the Tavoliere Plains. He defeats the papal army at Foggia and gains the loyalty of Apulia, on December 2.

England

King Henry III of England grants his eldest son the Lord Edward areas of land including crown lands in Wales, Ireland, the Channel Islands and Gascony. He is also given the cities of Bristol, Stamford and Grantham. The reason for these concessions is to give Edward experience of governing lands of his own before becoming a king. Edward is granted the Three Castles in Wales, Skenfrith Castle, White Castle and Grosmont Castle.
Summer – The Lord Edward travels from Portsmouth with his mother, Queen Eleanor of Provence, and Boniface of Savoy, archbishop of Canterbury, to marry the 13-year-old Eleanor of Castile, the half-sister of King Alfonso X of Castile. Henry III has demanded the marriage in exchange for ending the war with Alfonso. In August, the party arrives in Burgos, capital of Castile, where the marriage is due to take place.
November 1 – Edward marries Eleanor of Castile in the Cistercian monastery of Las Huelgas at Burgos.
