Not having a crown or the status associated with it.
The crownless king ruled with wisdom and fairness, despite his lack of a royal crown.
Crownless → It is formed from "crown" (from Old English "cyrn", meaning a circular ornamental headdress worn by a monarch) and "-less" (meaning without). The word "crownless" means without a crown or lacking a crown.
Think of someone who is 'without' ('-less') a 'crown' — that's what crownless means.
