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?
King Arthur King Arthur is a legendary British leader who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the late 5th and early 6th centuries AD. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians. The sparse historical background of Arthur is gleaned from various sources, including the "Annales Cambriae", the "Historia Brittonum", and the writings of Gildas. Arthur's name also occurs in early poetic sources such as "Y Gododdin".
English feudal barony In the kingdom of England, a feudal barony or barony by tenure was the highest degree of feudal land tenure, namely "per baroniam" (Latin for "by barony") under which the land-holder owed the service of being one of the king's barons. The duties owed by and the privileges granted to feudal barons cannot now be defined exactly, but they involved the duty of providing soldiers to the royal feudal army on demand by the king, and the privilege of attendance at the king's feudal court, the precursor of parliament.
