Stability

From EU3 Wiki

Overview

Stability (Stab) represents the social stability of your realm and is shown as a value from -3 to +3 (positive being better). This number will change through actions that you make especially when declaring war, through choices you make with events, as well as events that you are forced to accept. Your stability level is increased depending on how much you pay into the investment sliders.

At high levels you will receive more income from your taxes and at lower levels you will experience a greater risk of revolt across all your provinces. The importance of keeping your stability at least above negatives is paramount in your goal to keep your realm productive.

Diplomacy & Stability

Actions that affect your stability are cumulative. So if you declare war against a country that you have military access with and is the same religion, the total stability hit will be -6.

• -1: Declaring war against a country of the same religion (IN: same religious group).
• -1: Canceling a royal marriage.
• -1: Moving any domestic policy slider in any direction (IN: some slider changes have a chance).
• -1: Declaring war against a nation with whom you have a royal marriage.
• -1: Declaring war against a nation with whom you have good relations (100-149).
• -2: Declaring war against a nation with whom you have great relations (150+).
• -2: Declaring war without a casus belli.
• -3: Declaring war against a nation which is your vassal.
• -5: Declaring war against a nation with whom you have a truce.
• -5: Declaring war against a nation with whom you have military access to.
• -1 to -7: Changing your form of government, this depends on what form of government you currently have and what you are switching to.
• -3 to +3: As a result of some event options.

Cost of Stability

The cost of recovering stability is mainly a function of how many provinces you control (enemy owned temples help, colonies are included), but also note that it costs twice as much to reach Stab +2, and three times as much for +3, versus the cost to increase from -2 through +1.

Cost of a stability point = [ SUM( province_cost + Province_Religion_Modifier + event_triggered_province_modifiers ) - 5 * temples ] * Level_modifier * ( DP & other %modifiers )

The level modifier component of the cost is:

• 1 for stab -2 through 1
• 2 for stab 2
• 3 for stab 3

Province cost is determined as follows:

• base 25 (IN: 5)
• same religious group +25 (IN: 5)
• other religious group +50 (IN: 20)
• non-accepted non-group culture +50 (added in NA v2.1, removed in IN)

Province Religion modifier is determined as follows:

• Catholic 20
• Protestant 30
• Reformed 30
• Orthodox 15
• Sunni 20
• Shiite 20
• buddhism 20
• hinduism 25
• confucianism 20
• shinto 15
• animism 10
• shamanism 10

event-triggered province modifiers:

• oppose_monarch +30
• suppress_free_thinkers +20
• bureaucratic_expansion +25
• isolate_rebels +5
• peasant_negotiation +5
• rebel_negotiation +8

Some %modifiers:

• DP slider: innovative-narrowminded +25% to -25%
• DP slider: serfdom-freesubjects -5% to +5%
• National Idea: Church Attendance Duty -33%
• Badboy: +1% per point
• Inflation: +1% per point
• curia_controller -20%
• luck -50%

event-triggered static modifier:

• religious_tolerance -10%
• domestic_improvements -5%
• reduced_stability_cost -20%
• hanseatic_league +3%

triggered modifiers:

• revolution +3%
• peasant_war +3%
