省份忠誠度
 |
這部分內容可能已不適合當前版本，最後更新於1.5。 |
每一個省份都有一個 省份忠誠度（province loyalty） 值, 代表當地對中央政府的支持程度和這個省份對於支持命令的意願大小。不忠誠的省份會拒絕 遵守從首都的指令而且可能最終發動 叛亂或者加入一場 
內戰 - 管理省份忠誠度是運轉一個帝國的最重要的方面之一。
省份忠誠度每月根據所有省份忠誠度修正值的總和而變化。
.不滿值 - 其本身在很大程度上由人口的
幸福感所驅動，是影響省份忠誠度的主要因素，每個地區不滿值增加一點，忠誠度 -0.08 ，且根據該省在該地區的
人口比例進行縮放（因此，大城市對該省忠誠度的影響要比人口較少的定居點大得多）。
省長腐敗（在腐敗度為 100時為-0.25）以及缺乏一名省長來管理整個地區（-0.35）也會對省份忠誠度產生重大影響。減少省忠誠度損失的主要途徑是解決根源問題，如派遣地區部隊或增加民眾幸福感以減少不滿值或者更換腐敗的州長。
如果處理忠誠度損失的根源問題還不夠，還可以從以下方面提高省份忠誠度：
- 省份長官的
忠誠度（從50 忠誠度時的+0到 100 忠誠度時的+0.20 忠誠度) - 嚴酷鎮壓政策（每點省份長官
智略+0.03 , 加上+0.03基礎值） 
省檢察官省份投資（每級+0.01）- 不滿值為0的地區（+0.10，根據該省在該地區的人口比例進行縮放）
- various deities and omens ( +0.03 from passive modifiers, +0.04 per
100% omen power for omens) - the
Central Urban Spaces national idea +0.05) - the
Reduced Governorship invention +0.05)
Once a province's loyalty drops below 33, the province is considered disloyal and will refuse follow orders from the central government. Territories in disloyal provinces cannot be interacted with, blocking building construction, pop movement and cohort recruitment.
If a province's loyalty drops all the way down to 0, it will immediately rebel. A new state will be formed from the province (or possible a previously existing one that has been annexed), and it will either declare a independence war or join an ongoing one if there is a nearby province that has already rebelled. While the rebellion of a single province is unlikely to be successful, widespread discontent and unhappiness can be dangerous for even the strongest empires.

- 主條目：領土#省份首府
Every province has a 
省份首府（province capital） for each country that controls part of it, representing the center of the local administration. The 省份首府 gets significant bonuses and is generally the largest and most important territory in the province, determining who controls the province during a war and being one of the main recipients of 
enslaved pops. If desired, the 省份首府 can be moved during peacetime to a better location at the cost of province loyalty.
首都省份
The province with the country's capital is considered its capital province.
Every pop in the capital province has a 
+10% output modifier (stacking with the capital city and capital region modifiers). In addition, the capital province is fixed at 100 忠誠度 regardless of any province loyalty modifiers and so will never rebel.
The capital province is also where the special countrywide capital trade good surplus bonuses are gained. As the target of the 
capital trade routes modifier, which usually has contributions from the default commerce policy and country ranks as well as usually being the most populous province with a high population of 
nobles and 
citizens, this together means the capital province is usually the center of trade in a country with a large variety of imported trade goods.
省份投資

這部分內容可能已不適合當前版本，最後更新於1.5。 |
Provinces can be improved repeatedly with 省份投資（province investments） to improve the administration and infrastructure of the province. Province investments have a base cost of 
80 political influence each, modified by the specific province investment cost modifiers (
military provincial investment cost, 
civic provincial investment cost, 
oratory provincial investment cost, and 
religious provincial investment cost) that can be reduced by heritages and various inventions. There is also a cost of 
20 gold for every currently existing investment in the province, including others of a different type, which is not affected by the provincial investment cost modifiers. Each investment takes 6 months to prepare and reduces the output of the province by 1% during the process. The resulting effects are permanent as long as the province remains colonized and the owner isn't changed. Province investments cannot be cancelled once started, and only one investment can be made in a province at a time. Once a province investment is finished, a notification event will appear in the event queue.
It is also possible to get 
free province investments from forming nations and as a reward for certain missions, which allows a country to make a provincial investment without spending any political power or gold. Note that the 6-month duration to implement the investment still applies.
All 4 types of investments can be applied to the same province, unlimited amount of times.
- Install Provincial Procurators (Military): +0.01 Monthly Province Loyalty and +4% 人口產出
Promote Infrastructure Spending (Civic): 
+2.5% Population Capacity
Entice Business Investments (Oratory): 
+1 Local Import Routes
Make Religious Endowments (Religious): 
+1 City Building Slots
斯巴達 with the 
Magna Graecia DLC gets 2 unique investments for the military and religious slots, replacing the usual ones:
- Free Helots (Military):
+2% Integrated Culture Happiness, 
+5% Cohort Recruit Speed, and 
+6% Local Freemen Output - Commission Heroic Freize (Religious):
+4% Supply Limit and 
+3% Local Citizen Output
總督政策

|
這部分內容可能已不適合當前版本，最後更新於1.5。 |
Every province can have a 總督政策（governor policy） set which determines the priority of the province's administration. Governor policies allow a country to extract more from a province's population, deal with 不滿值 by increasing population happiness or cracking down on the population, build up the 
civilization value of the province's territories, and more.
When a governor is assigned, they chose a random policy based on the factors listed in the Chance column (with a base chance of 0). This includes directly reassigning a governor without having a vacancy first. As long as the region has a governor, the policy can be changed at a base cost of 10 political power, modified by the 
change governor policy cost modifier. Changing governor policy manually also gives 
tyranny based on the current ruler's popularity, scaling between 1.25 at 
0 ruler popularity to 0.25 at 100.
All policy effects are modified by the governor's 
Finesse, with the values below are given for the baseline level of 9 智略. Each point of the governor's 智略 above 9 increases the modifier by 10%, while each point below decreases it 10% to a minimum value of 10% of the base. This is described by the equation below:
- [math]\displaystyle{ \text{有效政策修正}=\frac{\text{总督智略} + 1}{10} \cdot \text{基础政策修正} }[/math]

這項政策將以省收入為代價，增加省份管理者的個人財富。一些惡毒的人物只對中飽私囊感興趣。 |

額外的機會每月改信人口，基於該總督的 |
激活時，這項政策會增加省份的不滿。 每個月都有機會讓非國教人口皈依你的國教。 同樣的，總督的熱枕會增加皈依幾率。 值得注意的是；總督皈依的人口的數量越多，他們獲得是聲譽也就越多。 為獲得最佳結果，最好讓政策持續激活一段時間。 通常情況下，檢查一個省是否仍然可以利用這一政策是有必要的。 |

該政策將使該省份中非國家主流文化人口每月都有幾率轉變為主流文化，同時提高省份叛亂度。你總督的智略將會提高同化幾率。 |

這項政策能大幅提高省份收入，但是會導致民眾時不時遷離該省，同時也會發生人口負增長。 |

這項政策每月給人民提供階級流動機會，旨在使公民、自由民和奴隸之間保持人口平衡。 |

儘管這可能會讓當地人口產生耗費，有時候處理不滿群眾的最好辦法，是展示我們的武力。 |

通過減輕該省人口的稅收和勞動義務，我們肯定會提高他們的滿意度。 |

通過着眼於基礎設施、文化傳播和學習，我們可以啟蒙這個省份內的人們。 一旦該省的文明度足夠，該政策還將在任何臨近的不可通行或不宜居住地形中的蠻族定居點傳播文明，緩慢安撫他們。 |
