Ambrosius Aurelianus

Ambrosius Aurelianus (Welsh: Emrys Wledig; Anglicised as Ambrose Aurelian and called Aurelius Ambrosius in the Historia Regum Britanniae and elsewhere) was a war leader of the Romano-British who won an important battle against the Anglo-Saxons in the 5th century, according to Gildas. He also appeared independently in the legends of the Britons, beginning with the 9th-century Historia Brittonum. Eventually he was transformed into the uncle of King Arthur, the brother of Arthur's father Uther Pendragon, and predeceases them both. Due to Gildas' description of him, Ambrosius is one of the figures called the Last of the Romans.
