"Æthelberht ([ˈæðelbeo̯rˠxt]; also spelled Ethelbert or Aethelberht) was the King of Wessex from 860 until his death in 865. He was the third son of King Æthelwulf by his first wife, Osburh. Æthelberht was first recorded as a witness to a charter in 854. The following year Æthelwulf went on pilgrimage to Rome and appointed his oldest surviving son, Æthelbald, as king of Wessex while Æthelberht became king of the recently conquered territory of Kent. Æthelberht may have surrendered his position to his father when he returned from pilgrimage, but resumed (or kept) the south-eastern kingship when his father died in 858." - (en.wikipedia.org 31.01.2020)
