Hey Addi, you have strayed into Ray territory. There is no evidence for a British "King" Arthur. BUT, there is real evidence for three of the characters from the "Legend" - Gawain, Tristram and King Mark, are certainly rooted in history. There is a hill fort near Queens Camel "Camelot"? That shows archaeological evidence of a Romano-Christian "castle" built at the top. I could go on for hours (yes, I am that sad) .. So, believe in Arthur (Artorius in the Latin scripted legends) if you wish. Perhaps he did exist. I deeply hope he did.
