The concept of treason can be dated back to the early Roman republic, but was defined by nebulous criteria, it would be the common laws of this time period which would most directly influence those customary in the court of King Arthur, a legendary British leader who, according to medieval histories and romances, led the defence of Britain against which invaders in the late 5th and early 6th centuries AD?
Treason in Arthurian legend The concept of treason can be dated back to the early Roman republic, but was defined by nebulous criteria. Frederic William Maitland, author of The History of English Law Before the Time of Edward I, has said that "treason is a crime [with] a vague circumference and more than one centre." Early French and Anglo-Saxon laws for the prosecution of persons deemed traitorous were inspired by, and in some cases, directly pulled from, late Roman and Germanic conceptions of the crime. It would be the common laws of this time period which would most directly influence those customary in King Arthur’s court — assuming its existence is founded in more than the legends and fables of medieval romances.
Brutus of Troy Brutus, or Brute of Troy, is a legendary descendant of the Trojan hero Aeneas, known in medieval British history as the eponymous founder and first king of Britain. This legend first appears in the "Historia Britonum", an anonymous 9th-century historical compilation to which commentary was added by Nennius, but is best known from the account given by the 12th-century chronicler Geoffrey of Monmouth in his "Historia Regum Britanniae". Notwithstanding this, he is not mentioned in any classical text and cannot be considered to be historical.
