Court Grandeur Expectations
The game also links it as Grandeur Expectations, Court Grandeur Expectation.
From the game's encyclopedia
You are expected to have a Court Grandeur Level that is high enough compared to your Realm Size.
As your Realm becomes larger, your subjects and the world at large expect your Royal Court to be equally grand.
If you do not meet expectations, various penalties will apply. On the other hand, if you exceed expectations, you will instead gain various bonuses.
The Expectations of Tribal Rulers are always the same as their current Grandeur.
