1291 CE
Alfonso’s reign has been marred by a constitutional struggle with the Aragonese nobles, which eventually culminate in the articles of the Union of Aragon—the so-called "Magna Carta of Aragon", which devolves several key royal powers into the hands of lesser nobles.
His inability to resist the demands of his nobles is to leave a heritage of disunity in Aragon and further dissent among the nobility, who increasingly see little reason to respect the throne, and bring the Kingdom of Aragon close to anarchy.
During his lifetime, a dynastic marriage with Princess Eleanor of England, daughter of King Edward I of England, has been arranged.
However, before meeting his bride Alfonso dies in in 1291 at the age of twenty-six and is buried in the Franciscan convent in Barcelona; since 1852 his remains have been buried in Barcelona Cathedral.
