Vassalization request towards a Machine Intelligence empire

A subject is an empire that has a special diplomatic relationship with another empire, called the overlord. In the default galaxy map mode, subjects have the same color as their overlord.

An empire can become a subject willingly via diplomacy, the acceptance dependent on a number of factors, particularly relative power. Having an overall superior or overwhelming relative power enables an empire to use the Subjugation Diplomacy status casus belli holder.png casus belli to forcefully make another empire a subject.

Subjects receive a −50% penalty to their Diplomatic weight.png diplomatic weight. In addition, operation difficulty is reduced between subjects and their overlord.

If they have fleets available, subject fleets tend to follow the overlord's.

Loyalty[edit | edit source]

Subjects have a secondary opinion type towards their overlord called Trade cat loyalty.png Loyalty that ranges from −100 to 100. Subjects with negative loyalty have the Disloyal attitude, which prevents any diplomatic agreements; subjects with positive loyalty have the Loyal attitude, which increases acceptance of diplomatic agreements. Loyalty can also be used as part of trade deals between the overlord and the subject.

Loyalty is gained or lost monthly based on subject's Diplomacy opinion.png opinion and terms of agreements; ethic compatibility, relative power, and overlord holdings have a lesser impact as well. A Trade cat action.png Pledge of Loyalty can also be negotiated via trade, adding Trade cat loyalty.png +1.5 monthly loyalty for the duration of the trade deal; if the subject's Diplomacy opinion.png opinion of the overlord is at least 150, the Pledge of Loyalty adds Trade cat loyalty.png +2.5 monthly loyalty instead.

If an overlord has multiple subjects, each subject gains Trade cat loyalty.png −1 monthly loyalty for every other subject. This penalty can be removed by the Civic feudal realm.png Feudal Society civic, Civic franchising.png Franchising civic, or the Ap shared destiny.png Shared Destiny ascension perk.

Trade cat loyalty.png Loyalty also grants experience to specialized subjects. In addition, certain resolutions increase or reduce Trade cat loyalty.png monthly loyalty as well.

Terms of agreement[edit | edit source]

All subjects and overlords have an Agreement towards each other, which may include certain obligations for the subject or the overlord. Agreements may only be changed once every 5 years. Reforming the government to add the Civic feudal realm.png Feudal Society or Civic franchising.png Franchising civics will remove incompatible terms from all agreements. Many agreement terms are restricted by subject type, primarily Diplomacy istributary.png Tributary, or by the Suzerains and Sovereignty resolutions.

Subject types[edit | edit source]

There are four types of regular subjects and three types of specialized subjects. There are also six types of preset, non-negotiable subjects.

Negotiable subjects[edit | edit source]

Type Subject Requirements Description
Diplomacy isvassal.png Vassal
  • No.pngAuth corporate.png Corporate overlord
  • No.pngCivic inwards perfection.png Inward Perfection
  • Relative power icon.png Within 60% technological difference
A vassal is a subject of another empire, often with little to no self-rule. Having signed a pact with a foreign power, they are often at the whims and mercy of their overlord, forced to bend to whatever rules and regulations their liege wishes. For some weakened empires, this is the final stopgap before they are consolidated properly into the fold, as they are signing away their autonomy bit by bit.
Diplomacy isprotectorate.png Protectorate
  • Relative power icon.png More than 50% technological difference
  • Overlord Not converting to specialist subject
A protectorate is a subject that is considerably weaker than their overlord, reduced to the point where their vassalage is considered a boon to them. Protected from the dangers of the greater galaxy, they can stabilize and improve their homeland as their liege looks out for them.
Diplomacy istributary.png Tributary
  • No.pngAuth corporate.png Corporate overlord
  • Relative power icon.png Within 60% technological difference
A tributary is a fairly autonomous subject, still in charge of their own affairs both internally and politically. They pay a considerable amount of tribute for their overlord's protection, and as long as the money is flowing, they are mostly free to do whatever they want.
Diplomacy istributary.png Subsidiary
  • Auth corporate.png Corporate overlord
  • Relative power icon.png Within 60% technological difference
A subsidiary is a subject with a considerable amount of self-rule, free to attend to their own affairs. They have signed away some of their independence for a deal where both sides are expected to support and aid one another.

Specialized subjects[edit | edit source]

Specialized subjects cannot be integrated and have additional effects. They can gain experience to increase in tier and gain additional effects. To reach tier 2, they need 1200 experience, and to reach tier 3, they need 3600 experience. Experience is gained monthly at a value of a tenth of the subject's Trade cat loyalty.png loyalty. Empires with the Origins imperial fiefdom.png Imperial Fiefdom origin will become a specialized subject of their choice shortly after the game starts. Protectorates cannot be made into a specialized subject; any other regular type of subject can be turned into a specialized subject through the agreement screen.

Overlord effects do not stack if there are multiple specialized subjects of the same type. The Relay Network effects require a Hyper Relay connection between the overlord and subject's capital systems and only apply to overlord systems connected to the same Hyper Relay network.

Non-negotiable subjects[edit | edit source]

Non-negotiable types of subjects cannot be proposed by regular empires and have preset terms of agreement. They do not allow subject integration or holdings.

Integration[edit | edit source]

Subjects that have Integration Permitted in the terms of agreement can be integrated into the overlord empire after 10 years via a diplomatic action, transferring control of all systems and ships to the overlord. All leaders, resources, and armies are removed, and new scientists will be required for the new science ships. Only one subject can be integrated at a time. Integration costs Influence.png 5 influence per month and has a base cost with the following formula:

If the player empire is integrated, the game is automatically lost.

Holdings[edit | edit source]

Main article: Holdings

Overlord holdings are special buildings which can be constructed on subject's worlds. The max number of holdings across all of a subject's worlds depends on the Holdings Limit agreement term as well as the Bureaucratic Surveillance resolutions.
