A '''subject empire''' is an [[Empire]] that has a special [[diplomacy|diplomatic relationship]] with another empire of superior strength. In the default galaxy map mode subjects have the same color as their overlord.

An empire can become a subject either forcefully through {{icon|casus belli}} wargoals or willingly, though the latter requires both a superior {{iconify|relative power}} and a positive [[attitude]] towards the superior party. If an empire becomes a subject willingly it brings a temporary {{green|+30}} {{iconify|Opinion}}. If it becomes a subject forcefully it brings a temporary {{red|-30}} {{iconify|Opinion}}

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

== Subject types ==
{{SVersion|3.3}}
There are a number of types of subjects available depending on the overlord's government. Most of them have to pay a certain tribute to the overlord.

If an empire switches its authority to or from {{iconify|Corporate}}, its subjects' types remain unchanged.

Subjects of an empire with the {{Iconify|Feudal Society}} civic may expand even if their subject type normally is not allowed to (e.g. vassals).

== Subject actions ==
{{SVersion|3.3}}
Subject empires have their attitude towards their overlord replaced by loyalty, expressing how content they are living under their Overlord’s rule. If a subject becomes disloyal they refuse any deal with the overlord and have a chance to start a war for independence, always waiting for an opportunity when something depletes the overlord's relative power (a taxing war, a larger uprising, a crisis, etc.). The loyalty is determined by the subject's opinion of the Overlord, which aside from the normal factors is also affected by the total military strength of all the subjects relative to the Overlord as well as that of those who support their independence.

An Empire is able to {{icon|support independence}} support the independence of another Empire's vassal. Doing this will count the supporting empire's fleet for the "relative power of subjects" opinion modifier, causing the subject to rebel if they stand a good chance of victory. If they do, the Empire supporting them automatically joins their war for independence. 

Subject empires do not suffer from border friction and can therefore in some cases be utilized as buffer states between two empires that otherwise would have significant border friction issues.

The opinion penalty from Relative Power is reduced by {{green|50%}} with the {{iconify|Feudal Society}} civic and by {{green|33%}} with the {{iconify|Franchising}} civic.

== Integration ==
{{SVersion|3.3}}
Vassals and Protectorates that an empire possess for longer than {{Hover box|10 years|3 600}} {{icon|time}} days can be peacefully '''{{iconify|integrate}}d''' by paying {{iconify|influence}}, at a rate of 5 {{iconify|influence}} a month. The base cost is 50, increased by 1 for each pop and 10 for each planet. Empires with the {{iconify|Shared Destiny}} ascension perk benefit from a {{green|-50%}} {{iconify|influence}} cost to integrating subjects. Only one subject can be integrated at a time. 

Once the integration is completed, all planets and ships of the subject are transferred to the overlord; the ships and starbases retain their graphic type. All leaders, resources and armies are removed; new scientists are required for their science ships.

Warning! If the player's empire is integrated by another empire the game is automatically lost!

== Releasing as a vassal ==
A player can create a vassal from their own territory by releasing one of their sectors as a vassal from the "Sectors" tab by clicking the "Create Vassal" button next to the sector they want to release. The player can then transfer additional systems to their vassal through the Trade option "Transfer System" if they so choose. 

Sometimes it is preferable to conquer systems and then release them as a vassal since this will create a vassal that shares the overlord's ethics and government. Notably, the vassal will be granted all its overlord's technology. The option to release a vassal is not available to {{iconify|Machine Intelligence}}s (except when you have no robot pops in the sector), {{icon|Undesirables}} Genocidal empires, species with {{icon|raiding}} Stellar Culture Shock, or the {{iconify|Hive-Minded}} and {{iconify|Nerve Stapled}} traits.
