23 November 1248
After a siege lasting from July 1247 — about sixteen months — Seville capitulated to Ferdinand III on 23 November 1248.
The Alcázar was delivered to the Castilians and Ferdinand's royal standard was raised on its tower, symbolising the surrender.
The prolonged blockade had worsened conditions inside the city, attempted outside relief failed, and its leaders lost hope of aid.
One month to leave
The Muslim population received one month to sell property and organise its compulsory evacuation.
Ferdinand's formal entry followed on 22 December, not on 23 November.
Seville had been governed during the siege by the military leader Axataf, or al-Saqqaf, with a council of notables — calling the defenders simply “the Almohads” obscures that recent political history.
A handover in stages
The transfer was a process rather than a single ceremony. Sources associate 23 November with the capitulation and delivery of the Alcázar, 22 December with Ferdinand's formal entry and the expiry of the agreed month, and some Arabic chronicles use 13 January 1249 for the completed loss or evacuation of the city.
The claim that Alfonso took Alicante on this same date is unsupported: documentary evidence does not securely establish Alicante's conquest date, and proposed dates range from 1248 to 1250.
