Why was King Arthur called the "Once & Future King?"?

[AxlConrad]

Could it be that Malory sought to flatter the monarch of the day by implying that the spirit of King Arthur existed in them, and would in all their descendants

I have been thinking about the entire weekend!! Do you know why?
I liked the Death of Arthur story, but it wasn't my favorite book. My favorite book is Catcher in the Rye and 1984

This was supposedly on his gravestone: "Here lies Arthur, the once and future king." They believed he would return to rule again.

That's one of my favorite books. Did you enjoy it?
