How long did king Arthur rule over Camelot?

King Arthur is a legendary figure, and the exact duration of his reign over Camelot is not definitively established in historical texts. Various legends and stories suggest that he ruled for around 15 to 20 years, but these accounts are often inconsistent and mythical in nature. Additionally, the concept of Camelot itself is more symbolic than historical, representing an idealized version of Arthur's rule rather than a specific timeline.
