This isn't our history though. This guy had every power on the planet completely willing to submit to his will and gave it up willingly. Not only would anyone targeting him have to deal with a guy who took on the combined might of two technologically superior nations and won, but they'd also have to deal with said technologically superior nations because they owe him.

I personally find it more likely that he abdicated the throne and helped restructure the other kingdoms into more representative government to prevent someone like Mantle's leader having sole power over a country again, not to protect himself.
