Making use of the methodology developed in his Origins of Arthurian Romances (McFarland, 2012), the author explores the question of King Arthur’s existence in several original approaches to the subject. Examining the extant literature and other evidence, the author searches for the truth of the who when and where of King Arthur. These explorations are grouped into historicity, geography and the years in which he flourished. The conclusion is that Arthur was indeed an historical entity and the author places him in a specific area and narrows the time frame of his period of activity.
