Faction

A faction is a coalition of nation states that are allied to each other.

Rules

A country may only create a new faction if the respective country rule is enabled. At the start of the game the three existing faction leaders  Germany, the  United Kingdom and the  Soviet Union, along with the  United States, have this rule. Other nations gain the capability to form their own factions through their national focus trees. Joining a faction is again limited by country rules. Depending on ideology and national spirits, countries need various amounts of world tension before they can join or ask someone to join a faction.

Faction members share military access with one another and see accurate intelligence in the diplomacy screen of their allies.

Factions rules can amend some country rules such as the ability to justify war goals on other countries of the same ideology or which actions are allowed in peace conferences.

Faction members can choose to leave a faction, but this causes a significant relations modifier faction traitor (-75 relations). A faction member cannot leave while fighting a war on the side of other members. The faction leader may kick another country out even while at war or disband the faction altogether if it contains no other members than themselves and their subjects. If the faction leader ceases to exist, the largest remaining member takes over.

If a country fights alongside major allies, it will only surrender once all of the majors in the faction have capitulated. For instance if Poland joined the Allies, it will not surrender before the United Kingdom and France capitulate, and will instead continue on as a government-in-exile.

Faction leader

A faction leader in HOI4 is the leader of a faction. The default faction leaders in-game are the  United Kingdom leading the Allies,  German Reich leading the Axis and the  Soviet Union leading the Comintern. They are usually joined by  Japan leading the Greater East Asian Co-Prosperity Sphere, and  China leading the Chinese United Front.

If the faction leader ceases to exist, the largest remaining member takes over.

Diplomatic Actions

The faction leader may kick another country out even while at war or disband the faction altogether if it contains no other members than themselves and their subjects.

Assuming Leadership

To be able to take over leadership in the faction they are in, a country must:

• Have more than twice the deployed manpower of the faction leader (subjects count, but at varying strength depending on autonomy)
• Have more than 150% of the factories of the faction leader
• Be in every war the faction leader is currently in
• Not having capitulated already

After paying 200 Political Power, the country can become faction leader, with all the benefits it entails.

Allies

The Allies are the main democratic faction, led by the United Kingdom.
