The Wars of The Roses. It was a thing (as in back in the day in the mid-to-late 1400s) and the plots and twists make for a fanciful story. One which found its place on HBO with eight seasons and more than seventy episodes. I confess I have not watched one (namely because I do not subscribe to HBO), but the actually history which inspired the storyline is of interest.
So, I turn to one of my favorite YouTube channels, "Royalty Now," which will give you an incredible look into the real story behind the "Game" and what the main characters may have looked like.
