The Death of Alfonso VIII and Eleanor of England (1214) and the Ascension of Henry I of Castile

On October 5, 1214, King Alfonso VIII of Castile passed away at the age of fifty-nine in Gutierre-Muñoz. His death marked the end of a reign that had seen Castile's consolidation, military triumphs against the Almohads, and diplomatic ties with European royalty.

His wife, Queen Eleanor of England, daughter of Henry II of England and Eleanor of Aquitaine, was reportedly so overcome with grief that she was unable to attend her husband’s burial. Their eldest daughter, Berengaria of Castile, took on the responsibility of presiding over the funeral.

Just twenty-eight days later, Queen Eleanor succumbed to illness and passed away, possibly from the overwhelming sorrow of losing her husband. She was buried at Las Huelgas Abbey in Burgos, a monastery she had patronized.

The Succession of Henry I and Berengaria’s Guardianship

With Alfonso VIII's death, his ten-year-old son, Henry I, ascended the throne. Named after his maternal grandfather, Henry II of England, the young king required a regent to rule in his stead. His elder sister, Berengaria of Castile, wife of Alfonso IX of León, assumed this role, effectively controlling the kingdom during his minority.

Henry I's reign, though brief, was marked by political instability, as Castile’s powerful nobility sought to assert influence over the young monarch and the future of the realm.

Rudolf III of Burgundy had presented to his wife Irmengarde a new castle (French: neu-châtel, in antiquated German: Welschen Nüwenburg or Newenburg am See) in 1011, built on the northwestern shore of Lake Neuchâtel in western Switzerland.

The first counts of Neuchâtel had been named shortly afterwards, and in 1214 their domain receives a charter.

Bielefeld is founded by Count Hermann II of Ravensberg in 1214 to guard a pass separating the Northern and Southern Teutoburg Forest.
