Spoiler alert if you care about getting spoiled, I don't know how far you are into the story.
In the One Piece story, their World Government was formed by 20 elite bloodline families. Very similar to what we talk about here with the 13 bloodline families. Makes me wonder if the author just straight up browses conspiracy boards and incorporates those ideas into his story lol: https://www.opfanpage.com/wp-content/uploads/2020/01/6q3wi380rr941.png
I watched the anime version a lot back in the 2000s and didn't realize it was an analogy.
