Siege of Jaén (1230)

The battle resulted in a Jayyānese victory after the Castilian withdrawal and abandonment of the siege immediately following the death of King Alfonso IX of León.

The siege of 1230 presented a greater challenge than the one in 1225 because the city defenses had been significantly improved by the ruling Taifa of Jayyān as they had expected further Castilian aggression.

Their placement in this location was an apparent punishment for having arrived late to the city's previous siege five years before indicating an unforgiving temperament on the part of Ferdinand III.

mandolos possar el rey en una cabeza que es sobre el alcaçar, e era logar que non se podrien acorrer quando menester les fuesse los de la hueste...By September, after a siege of around four months, Ferdinand III was obliged to withdraw prematurely a second time from his siege of the city, this time due to the death of his father, Alfonso IX of León.

Jaén would finally be permanently taken by Castilian forces in 1246 when the forces of Castile and members of the Order of Santiago under Ferdinand III of Castile and Paio Peres Correia, Grand Master of the Order of Santiago, returned to finish the capture of the defiant city, defeating a Granadan army under Muhammad I.
