The White Ship sinks in the English Channel, drowning William Adelin, son and heir of Henry I of England.
The White Ship (French: la Blanche-Nef; Medieval Latin: Candida navis) was a vessel transporting many nobles, including the heir to the English throne, that sank in the Channel during a trip from France to England near the Normandy coast off Barfleur, on 25 November 1120. Only one of approximately 300 people aboard, a butcher from Rouen, survived. Those who drowned included William Adelin, the only legitimate son and heir of Henry I of England, his half-sister Matilda of Perche, his half-brother Richard of Lincoln, the earl of Chester Richard d'Avranches, and Geoffrey Ridel. William Adelin's death led to a succession crisis and a period of civil war in England from 1135 to 1153 known as the Anarchy.
