The Siege of Jaén begins, in the context of the Spanish Reconquista.

The siege of Jaén was one of many sieges on that city during the Spanish Reconquista. The siege was carried out from 24 June through September, 1230 by forces of the Kingdom of Castile commanded by Ferdinand III of Castile against the defending Taifa of Jayyān (جيان). 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.

June 24 is the 175th day of the year in the Gregorian calendar; 190 days remain until the end of the year.
