教宗国（英文：Papal State） 是神权时代（教宗时代）教宗力量的体现。1444年游戏开局时， 教宗国拥有省份罗马，安科纳，翁布里亚，罗马涅和阿维尼翁以及附庸 乌尔比诺。相对于北意大利地区的其他国家， 教宗国体量相当之大。尽管如此，在游戏早期它仍然会遭到来自邻国的入侵，如 佛罗伦萨， 普罗旺斯也会因为对其相邻的内陆孤立省份阿维尼翁有领土诉求而入侵。 那不勒斯由于开局处于联合统治状态而不会有任何威胁，但是如果它脱离 阿拉贡的联合统治，它将会试图征服教宗国。
Advantages of the Papal State
The Papal State is virtually guaranteed maximum prestige. Their unique government type gives +1 prestige and their national ideas give another +1 prestige and -1 prestige decay. With another +1 possible from 100 Devotion the Papal State's prestige drifts to 100 with little player intervention. This provides another -10% aggressive expansion impact and a +50% Better Relations Over Time bonus in addition to the -10% aggressive expansion impact from the national ideas.
On top of this, the Papal State has a -20% cost to fabricate claims bonus. Claimed provinces are easier to core and start with lower local autonomy—autonomy that will quickly drop thanks to the Papal State's government type.
On top of these bonuses, 100 devotion, high clergy estate influence and one of the Papal ideas can provide a total of +65% global tax modifier in a region with high tax base.
The papacy government type is also a fixed rank Kingdom tier government, thus granting the unique ability to join the HRE while keeping the Kingdom Rank, even without an electorate. Like all the theocracies the Papal State does not suffer a stability hit on monarch death, nor regencies. The Papal State is similar to other theocracies in not being allowed to turn their ruler into a general, though The Papal State does not choose an heir.
The Papal State has several unique events and decisions that provide several permanent perks:
- The Vatican library grants -5% technology cost and the player's choice of -2 national unrest, +1 diplomatic reputation or +5% discipline, all of which stack with the national ideas bonus.
- The Sistine Chapel decorated by Michelangelo, possible only if the Sistine chapel is built but not yet decorated in between 1465 and 1564, offers a -5% idea cost.
- The Swiss Guard may give +10% global manpower modifier if the player has good relations with 瑞士.
- The Papal State can also form the Kingdom Of God, which provides another +10% manpower on top and additional prestige and devotion, and disables the curia.
The Papal State also has a very influential Clergy estate that does not require any amount of provinces to remain loyal to the Pope. This means that the Papal State is the only Catholic nation that can keep all its estates loyal while assigning a mere 10% of his development to the nobility. It will also grant the ability to demand support from the Church often, for frequent administrative power gains. Given that the Papal State can obtain notable reductions on technology and idea costs and that it rarely loses stability at all, it will never lack precious administrative power, even when actively annexing and coring considerable amounts of land.
Lastly, since the yearly papal influence gained by Catholic nations is based on the Papal State relation score with them, all the Catholic nations will try to keep their relationship maxed, avoiding cases of the Papal State being unable to ally a Catholic nation because his own opinion toward said nation is negative. This also means that Catholic nations who become hostile or rival towards the Papal State will rarely gain control of the curia and are going to lose most of the perks of the Catholicism, thus granting the Papal State an automatic advantage toward enemies and rivals in the Catholic world.
All of this means that as soon as the Papal State negotiates the opening stages of the game, perhaps by appeasing 奥地利 and joining the Holy Roman Empire, is set to become a very offensive player in the European scenario, capable of expanding fast with minimal negative repercussions.
The Papal State starts small, surrounded by acquisitive opponents. The right combination of alliances should forestall aggression, but the fact that almost all the northern Italian states are in the HRE will hinder expansion. The Shadow Empire event in 1490 may remove the Italian princes from the HRE. 威尼斯 and 那不勒斯 are potential non-HRE rivals. As with all theocracies, the Papal State cannot have royal marriages or personal unions, and since it is not a monastic order cannot make its leader a general. Unlike other theocracies it cannot become an Empire, and cannot change or reform its fixed government type. The fixed rank and government type also fix the number of possible states to a maximum of 15 before technology and idea bonus, that will be somewhat lacking after the conquest of the Italian peninsula.
Papal State is also locked into Catholicism, but cannot get the perks other Catholics get from spending papal influence and has to deal with the Reformation without the ability to adopt a more tolerant religion, starts the game with the Blasphemy Act modifier that grants +1% missionary strength, but also a -1 tolerance of heretics that stacks with the usual Catholic low heretic tolerance for a total of -4 tolerance of heretics at the start of the game. Provinces that convert during the Reformation will be locked out of conversion for 30 years, and that is a massive swing towards rebellion and due to the very low heretic tolerance, not even adopting the humanist idea group can prevent the Papal State from a loss in religious unity. Low religious unity will raise corruption, that will increase all monarch power costs up to intolerable amounts unless rooted out by investing time and an exorbitant amount of gold. Luckily the usually high stability will help in keeping rebellion and corruption under control, and the Papal State starts with a +25% religious unity modifier that will prevent things from getting truly nasty.
Other than that, the main problem is that after Italy is consolidated the Papal State is going to be surrounded by 法兰西, 奥地利, 匈牙利, and the 奥斯曼. Avoiding a direct border will help France remain friendly.
Influence Over the Curia
The Papal State starts the game as the Curia Controller, but since it can't gain papal influence it can't invest influence to keep its Curia Controller status.
Instead the Papal State has an automatic amount of influence invested in the curia controller election based on the number of the existing cardinals in the Catholic world, so struggling to keep the full 49 cardinal seats filled, when chance is given by event, will maximize the Papal State ability to be the next Curia Controller. Encouraging a hostile diplomatic game towards nations that gain several cardinal seats, with an intelligent use of rivalries, hostile diplomatic relationships and event choices, will eventually lower considerably their papal influence gains, thus reducing the influence over the Curia of the most active participants to the papal election.
A more uncommon way the Papal State has to improve its control over the Curia is the ability to willingly increase the death chance of the Pope to cause an immediate new election. A few events available to the papacy include choices that could result in the death of the Pope, so picking those choices when the Curia is under foreign control will give a chance for a new election. Due to the papacy government type there will be no stability hit on monarch death.
Reform Desire Control
Among all the Catholic Nations the Papal State is in the unique position of being actually capable of greatly lower the reform desire and slowing down the reformation process.
The Veneration of relics, Indulgences and Simony related events for the Papal State grant a choice between a small source of income for free and the banishment of said practices from the Catholic world at the cost of -1 stability. For each practice banished not only the reform desire is decreased by a notable -10%, but also the related event is permanently disabled for all the Catholic nations, thus putting a permanent stopgag to the most important sources of the reform desire itself.
Lastly the witch trial event can grant another -10% decrease to the global reform desire for no cost.
Needless to say, if the Papal State is willing to pick all the reform desire lowering choices the reform can be slowed to the point of being irrelevant for most of the game. Due to the Papal State abysmal heretic religion tolerance and the consequent rise in corruption due to low religious unity, this should be the preferred approach.
这个决议基本上是在北意大利的大部分土地被吞并时才可用。决议可用需要吞并几个意大利国家以及奥地利的核心省份特伦托。即使没有玩家的干预，获取奥利地的该领土也是容易的。因为特伦托在游戏开局属于威尼斯文化，且有两个开局不存在的国家拥有核心。然而，这个决议的作用是有争议性的：一方面，它提供+10% 人力，+1 威望，+1 奉献度，获得对整个意大利地区的永久宣称；另一方面，它会移除教廷与教监，削弱所有的天主教国家。通常而言，教宗国是无法获得或者投资教廷影响力的。但是，如果全部的49个枢机席位分散在欧洲的天主教国家中，那么教宗国成为教监的概率会高于平均水平。因此，完成这个决议的后果应该由玩家仔细权衡。
- Allying Austria and improving relations to maximum can allow the player to join the HRE.
- 威尼斯 is a tempting early target. The Papal State begins with 乌尔比诺 as a vassal, and Urbino has claims on Venetian territory. 奥地利 will usually rival Venice, so if they are allied they will be an enthusiastic participant.
- 那不勒斯 may be vulnerable if they break out of their personal union with 阿拉贡.
- 法兰西 can be powerful ally - at least until the player shares a border with them.
- Selling Avignon to France might be easier than trying to defend it, however 普罗旺斯 is a possible starting rival that owns an estuary city in the Genoa trade node - making it a profitable conquest. By excommunicating them first you might get rid of their allies, and you get a casus belli with reduced aggressive expansion impact.
- Influence has a lot of synergy with the Papal State's national ideas, while the core costs discount from Administrative is very helpful in the Italian region and synergize well with all the Papal State administrative power discounts and gains. Either of them should be the first idea group.
- Stacking discipline by completing offensive and quality idea groups and building the military version of the Vatican library will grant the Papal State one of the highest discipline bonus in the whole world (120%).
