Death Alfonso IX of León and Galicia died on 24 September 1230. His death was particularly significant in that his son, Ferdinand III of Castile, who was already the King of Castile, also inherited the thrones of León and Galicia from his father. This was thanks to the negotiations of his mother, Berengaria, who convinced her stepdaughters to renounce their claim on the throne. In an effort to quickly consolidate his power over León, Ferdinand III abandoned a military campaign to capture the city of Jaén immediately upon hearing news of his father's death and traveled to León to be crowned king. This coronation united the Kingdoms of León and Castile which would go on to dominate the Iberian Peninsula.
