Changing the culture of my heir
Russian Tsars have always taken young dusky beauties as wifes, because there's a lot of them and it's easy to find a genius one. This has always worked fine, except this time my heir grew up to be a Turk. An empire of a million little counts suffers enough problems during succession crises, but a foreigner on the throne turns it into a million little counties overnight, and even the deep coffers of the new Tsar, er, Sultan are not enough to bribe them all.
Is there a way to make my son embrace Russian culture if he's a grown man already?
