Drawings Featuring Crowns - Representing Authority and Power

Crowns have a long history on the Eurasian continent, with many cultures using them to signify power and wealth at some point in history. Their design can vary between a simple one using only precious metal or an elaborate one comprised of the finest materials and gems.

King Halo (from Uma Musume Pretty Derby) obviously deserves her crown, but what about the other characters featured in the illustrations below?
