Any time you see a female monarch who's in power for half a century, it's worth looking into, because you're gonna see a beautiful story about how to wield power. When you can't rely on being able to physically overpower your opponents directly - when "I'm the biggest guy in the room, so fuck you" isn't in your toolkit - anyone who gets and keeps power does so by some really, really sharp tactics.
(and yeah, napoleon, et al, but those are in the same vein - short guy runs the world, probably an interesting story there too.)
