From Veritas et Fortitudo
Jump to: navigation, search

Veritas et Fortitudo has completely reworked the vanilla vassal system. In Veritas et Fortitudo, a vassal progresses through a number of stages of integration each providing increasing control and benefits for the overlord.

Vassal Integration Stages

Stage I — Suzerainty
Stage II — Dependency
Stage III — Dominion
Stage IV — Vassal
Stage V — Integrated

Rebellious Vassal

A suzerainty which drops to 0% integration becomes rebellious, receiving a +50% to liberty desire for ten years; when this happens, foreign nations can support their independence. Their integration progress is locked at 10% for the duration of the liberty desire modifier; the modifier can be reapplied if it afterwards falls to 0% again.


Designated by a red shield, a suzerainty is a newly acquired vassal which enjoys signficant autonomy. Loyal suzerainties can conduct diplomacy with anyone who is not an enemy of their overlord and wage war against anyone not protected by them; disloyal ones can conduct diplomacy as they please. They are not required to fight on behalf of their overlord who only recieves 25% of the regular vassal tribute.


Designated by an orange shield, a dependency has become reliant on their overlord but still retains local autonomy. A dependency may only conduct diplomacy amongnst other subjects of the overlord. They will fight on behalf of their overlord who only recieves 50% of the regular vassal tribute.


Designated by a yellow shield, a dominion's political apparatus is reliant on the overlord in order to function. Dominions conduct no foreign policy and they will fight on behalf of their overlord who recieves 75% of the regular vassal tribute.


Designated by the traditional blue shield, a vassal is considered an extension of the overlord's realm. In addition to providing full tribute, only a vassal can be designated as a March of the overlord.

Integrated Vassal

A vassal subject which has reached 100% integration gives added bonuses to it's overlord and can be annexed.

Integration Modifiers

On a monthly basis, the following are applied to adjust the percentage of integration:

§R-0.1§! for 'ambitious vassals' (granted when the vassal ruler has a composite score greater than 10 and in some historical situations)\n\nIntegration can be accelerated when advancing to a new stage:\n 50% chance of §G+20%§! progress\n 40% chance of §G+30%§! progress\n 10% chance of §G+40%§! progress.

(*) An ambitious vassal is considered one where the ruler has a composite score greater than 10 and is also granted in some historical situations

Accelerate Vassal Integration

At each stage, you are given the option to accelerate the integration process for a cost in ducats and monarch points (Admin for the first 3 stages, Military for the 4th and Diplomatic for the 5th). This provides a random reduction according to the following table:

Chance Bonus
50% 3.3
40% 4.2
10% 5.0

Vassal Growth

For each province a vassal gains, it loses 50% of it's current integration and will revert to the prior stage or become rebellious if it reaches 0%. Integrated vassals can have one province added to the m without penalty before reverting to regular vassals and continuing the integration process.

Special Subject Types

These subject types have been added for Veritas et Fortitudo to designate special circumstances


Designated by a vassal symbol with the French flag on the shield, they represent most of France's subjects at the start of the game, these subjects will not integrate and are allowed to conduct war and other diplomacy amongst themselves; France cannot be forced to release them in any peace accord. Fealties will revert to the normal vassal system either when the Hundred Years War ends or if a fealty reaches 80% of France's military strength.

Papal States

Designated by the papal keys symbol. The sovereign cities nominally subject to Papal rule, while happy to enjoy the Pope's protection, have no intention of submitting to his authority. These subjects will not fight for independence but neither will they support the Pope in his wars nor pay him any form of tribute. Only military action will bring these states to heel.


The Hejaz subject starts under the protection of the Mamluk sultunate or Ottoman Empire. Hejaz will not fight in wars nor can it declare independence and it pays no tribute to it's overlord but does transfer trade power. Hejaz is responsible only for the maintenance of the Muslim holy cities and surrounding lands; it will refuse to administer any other territories. Hejaz can be released or transferred in a peace treaty; if released or if it's overlord weakens they may seek an independent path or a new overlord to protect them.

Russian Princes

The Russian princes are the tribute states of the Kipchak Horde; one of them (the Grand Prince) is the Enforcer for the horde overseeing most of the other princes. A prince who becomes large enough (either more provinces or a larger army than the enforcer) will be under the direct rulership of the horde and may challenge the Grand Prince for superiority. The Grand Prince can end the rulership of the Horde by defeating them (>60% warscore).

Swiss Confederate

The formal Switzerland tag (with the government of Swiss Confederation) can offer other Swiss states the opportunity to join their confederation if they have 200 relations and at least 90 trust. These subjects operate like vassals except that they do not go through the standard integration process, have a severely curtailed liberty desire, and can be annexed diplomatically with relative speed.

Hanseatic Union

A specialised personal union for the Hanseatic league where the member states share a ruler but cannot be integrated and pursue their own foreign policies.
