June 19 – King Louis IX of France ("the Saint") orders all Jews found in public without an identifying yellow badge to be fined ten livres of silver. He also confiscates goods from the Jewish population to fund the Eighth Crusade.
September – An Aragonese contingent under King James I ("the Conqueror") sails from Barcelona to the Holy Land but is caught in a storm and badly damaged. One squadron reaches Acre, but later returns to Aragon.
