It really wasn't all that hard, taking over the kingdom. I had a few hundred years to amass my fortunes, and once the nobility saw through my charade of strikingly similar genes passed from son to son, it actually got easier! I wish I'd've come out to them hundreds of years ago so they'd treat me with the respect I deserve.
Anyway, it's been fun. My subjects really like what I've done with the place, my armies are strong and well fed, and advances in technology are finally letting people get out of the fields and focus on furthering goals of science and medicine.
But I'm a little bored. First, I really don't want to limit myself to a single kingdom. I'm still a few hundred years away from any sort of instant communications that would allow me to truly have a world empire, but I'd love to start with at least just this continent. But without being able to communicate back home quickly, I am worried whoever I choose to run my kingdom will let it fall apart while I'm gone. Further, once I finally do take over the continent (and the world) I need a process in place that allows me to have the freedom I deserve for taking over the while without losing my position of power.
Because I have such a high approval rating among my subjects, I'm thinking I could have some sort of democratic election. But if my subjects pick someone who is ultimately bad for the kingdom (not that it would happen, but you never know,) I need a solid escape valve.
If it helps, I do have a vague notion of things that haven't been invented yet, including things from 1300 AD (which is about present day) and about 1000 years after that. You should totally see what's in store for you in 2128, it will blow your mind!* But I don't have specifics enough to really recreate them from scratch. I'd be able to have a meaningful conversation with your typical college graduate about notions of government, economics, the scientific method, and the various inventions over the years.
What system can I use to find someone to rule my kingdom(s) that will 1) last for hundreds or thousands of years 2) give me the freedom to conquer the rest of the world and 3) keep my people happy?
