>shouldn't the nature of polities as heritable property be one of those mechanics?
It would be except that a lot of cultures who practice Stem Nuclear and Absolute Nuclear family systems are represented as practising Egalitarian Nuclear family systems.
Stem Nuclear: Eldest son takes everything, other sons get nothing. Practised by Germans, most Norwegians, Swedes, the Irish, the Scottish, the Czechs, and the Occitans as well as some other southern French & northern Spanish cultures.
Absolute Nuclear: Arbitrary inheritance up to the father, he can give one son everything, split it equally, split it unequally, whatever he wants. Practised by English, Dutch, Danish, some Norwegians.
Egalitarian Nuclear: Equal division of inheritance among all sons; Paradox treats all Europeans as following this system by default when historically only a minority did. IRL, practised by central French, north & south Italians (but not central Italians, they practised a communal large-family system similar to asians; as did the majority of Slavs, and the Finns), Romanians, Poles, most Spaniards
Often these were not absolute laws, of course, and in the nobility's case in particular, politics often trumped cultural tradition. If you were trying to manage too large a realm and/or really wanted all your sons to be at relative peace with each other you might choose to partition rather than risk civil war, even if your culture normally didn't do absolute/egalitarian inheritance. And likewise, as the French eventually started doing, you might have egalitarian inheritance in general but you pass the throne down to one son without territorial division because you realize it's bad for the realm to keep splitting it.
Forcing partition on everyone is retarded, it should be an option, with a risk of civil war if you have multiple sons who have a lot of political or military capital and you don't partition.
