Estate

Estate (Page 1)
In Common Universalis, estate acts as a true political power that fights with or against central power. Each province has an influence for each estate, including Administration Centrale - your central government( which is put into estate panel for convenience ), and the estate with highest influence gains control of the province. Province estate influence is affected by province development, literacy, buildings, modifiers, etc. and countrywide estate influence. For example, Burghers estate may have high influence in a province with high commerce and literacy.

Estate Reform Desire (Page 2)
Like in real world, each estate(excluding Administration Centrale of course) has political persuit. They have a preference for each type of government reform, and may take different means to pass their favorable ones. Whether they choose to remain silent, send a polite request, or resort to violence, is determined by Estate Reform Desire. In worst case, they may ignite a rebellion( or revolution if you call so) in your empire.
