A direct result of William Adelin's death was the period known as the Anarchy. The "White Ship" disaster had left Henry I with only one legitimate child, a second daughter named Matilda. Although Henry I had forced his barons to swear an oath to support Matilda as his heir on several occasions, a woman had never ruled in England in her own right. Matilda was also unpopular because she was married to Geoffrey V, Count of Anjou. He was a traditional enemy of England's Norman nobles. Upon Henry's death in 1135, the English barons were not sure they wanted Matilda as queen Regnant.
