Faction

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

Rules[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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

Other possible factions[edit | edit source]

All countries (except the British Raj with Together for Victory) can acquire the ability to create factions through their national focus tree. In general, these have no default name, with the player choosing a name when inviting the first member. Several specific factions, inspired by counterfactual history, do have pre-set names, however, and are listed below.

French Alliance[edit | edit source]

If France condemns German ambition in Czechoslovakia, they will automatically form this faction with Czechoslovakia.

Possible members

France (automatic)
Czechoslovakia (automatic)

Stresa Front[edit | edit source]

If France chooses the focus 'Ratify the Stresa Front', they can form the alliance with Italy and potentially the United Kingdom.

Possible members

Little Entente[edit | edit source]

The Little Entente is a faction that can be formed by France with the 'Strengthen the Little Entente' National Focus. When this faction is formed, France won't join the Allies. Based on the pre-WW2 alliance with the objective of preventing Hungary from rearming and/or a Habsburg restoration in Austria.

Possible members

Treaty of Reciprocal Assistance[edit | edit source]

If the United States takes the focus 'Hemisphere Defense', they will form this faction and automatically invite all Latin American nations of its ideology into it. Note that the nations invited will differ depending on what ideology the US is at the time it completes the focus.

The faction itself is likely based on the real-life Inter-American Treaty of Reciprocal Assistance, a treaty that was signed after World War 2. Unlike the real-life treaty, which merely invited countries based on their locations, the in-game faction will only invite Latin American countries of the same ideology as the US, meaning that Venezuela, Argentina, Paraguay, Brazil, Bolivia, Peru, Dominican Republic, El Salvador, and Mexico will not be invited if a Democratic US was to form the faction, despite having signed the treaty in the first year (although should a Fascist or Communist US be the one to form the faction, the countries belonging to those ideologies would be invited instead).
