Cador (Latin: Cadorius) was a legendary Duke of Cornwall, known chiefly through Geoffrey of Monmouth's pseudohistorical Historia Regum Britanniae and previous manuscript sources such as the Life of Carantoc. Early sources present Cador as a relative of King Arthur, though the details of their kinship are usually left unspecified. Historicity Many stories involving Arthurian figures were likely passed down orally, which has led to many different interpretations and versions of the people and characters mentioned. Scholars generally question the historical accuracy of these tales. Evidence shows that people like Arthur may have been real historical figures. However, most of the deeds of Arthur have been discredited. Because of this, the people he is associated with and their stories could be solely a part of the orally passed down myths of Arthur's legacy and not true history. One of these figures was Cado, a successor of Geraint ab Erbin and a close associate of Arthur. Cador, the Duke of Cornwall, was a member that was summoned to Arthur's court. While it seems that Cador the Duke of Cornwall could have been a real historical figure, interpretations and stories that include him are very diverse in their information so understanding the true historical context of figures like him is difficult. Sources like King Arthur: The Truth Behind the Legend explain how the Arthurian history has been mixed with fact and fiction which means many events and figures could not have been accurate, “The Arthurian saga is nevertheless much more than a hotchpotch of tales made up by medieval minstrels, and it is essential to try to separate the Arthur of the romances—the Arthur of Geoffrey of Monmouth, Thomas Malory and the medieval troubadours—from the historical Arthur—the dark age warrior on whom all the rest of the super-structure was built”. Scholars were able to narrow down the true historical facts of Arthur's life to two things, “Some scholars have taken everything out, argued everything away, leaving just two brief mentions in the Easter Annals: 516: Battle of Badon, in which Arthur carried the cross of our Lord Jesus Christ on his shoulders for three days and three nights, and the British were victors. 537: Strife of Camlann, in which Arthur and Medraut perished [or fell]” (King Arthur: The Truth Behind the Legend). However, there is still a lot of information that is debatable of being facts or a part of the pseudohistory. Arthur,
