Arthur, it seems, is claimed as the King of nearly every Celtic Kingdom known. The 6th century certainly saw many men named Arthur born into the Celtic Royal families of Britain but, despite attempts to identify the great man himself amongst them, there can be little doubt that most of these people were only named in his honour. Princes with other names are also sometimes identified with "Arthwyr" which is thought by some to be a title similar to "Vortigern".
