Centralisation is the process where a monarch tries to divert the power over the state from the Nobles to himself. The nobles are often not happy with changes like these and tend to oppose them. This struggle is represented in the game by the centralisation mechanic, Where are less centralised state Is more stable but weaker, and a more centralised state Is stronger but less stable.
As of version 2.00 The centralisation mechanic is presented very similarly to the 'Absolutism' mechanic in the base game. The major difference is that you cannot get centralisation from actions such as Harsh treatment and Lower autonomy, and is instead gained passively by a policy or increased by certain events and decisions
Ways to change centralisation Edit
- Enacting 'Centralise the state' policy -- Cost: 1 administrative power per month, effect: +0.4 yearly centralisation
- Some desicions to form countries
- Event choices
- +0.05 Yearly centralisation per Stability point
- Choosing 'Decentralise to Stabilise our Nation' decision -- Cost: 100 administrative power, effect: -10 centralisation, +50 stability points, -5 National Unrest for five years.
- Prince or Emperor of the HRE (-0.10 per year)
Effects of centralisation Edit
As of version 2.00, Having 100 centralisation has the following effects.
NOTE: These effects are scaled and having less centralisation will have these effects to a lesser degree.
- National unrest: +10.00
- Provincial trade power modifier: -10%
- Stability increase interval: +50%
- Yearly inflation reduction: +0.125 [not sure on amount]
- Trade power abroad: +20%
- Land force limit modifier: +12%
- Fort maintenance: +25%
- State maintenance: -20%
- Technology cost: -30%
- Core creation cost: +30%
- Income from vassals: +40%
- Monthly autonomy change -0.40%
- Max promoted cultures: -5
- Liberty desire in subjects: +30%
Reaching 40 centralisation is required to annex vassals.
When feudal monarchies get vassals or Personal Union minors they get extra diplomatic slots for vassal upkeep (up to 3 if you have 3 subjects). Centralizing your country removes this ability. At 20 centralisation you get at most 2 extra diplomatic slots for subjects and at 40 you get only one. Presumably at 60 this ability is lost entirely.
Max Centralisation Edit
Just like absolutism in the base game there is a max centralisation, Which can increase or decrease depending on various factors
