A faction is a coalition of nation states that are allied to each other.
A country may only create a new faction if the respective country rule is enabled. At the start of the game only the three existing faction leaders Germany, the United Kingdom and the Soviet Union 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 have surrendered. For instance if Poland joined the Allies, it will not surrender before the United Kingdom and France surrender.
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.
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.
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.
The Chinese United FrontEdit
The Chinese United Front is a smaller faction that may be formed by Nationalist China in order to unite the Chinese against the Japanese invaders. Note that it does not exist in the 1936 start date. The United Front will be formed by China, which will annex the Warlords states (except Sinkiang) and People's Republic of China will annex Shanxi. With Waking the Tiger, the Chinese United front can be formed by both China and Communist China (With many different names depending of who forms it) and will not only include those two nations but also the Warlord cliques ( Shanxi, Xibei San Ma, Yunnan, Guangxi Clique and Sinkiang).
Greater East Asia Co-Prosperity SphereEdit
The Greater East Asia Co-Prosperity Sphere (formerly known as Daitoa Kyoeiken) is a faction formed by Japan after following the focus Purge the Kodoha faction and Greater East Asia Co-Prosperity Sphere. It's formed with the objective of creating a pan-Asian bloc led by Japan.

Other possible factionsEdit
All countries (except the British Raj with Together for Victory, though this may be an oversight) 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.
Novus Imperium RomanumEdit
- Possible members
The Berlin-Moscow AxisEdit
- Possible members
Asian Communist SolidarityEdit
The French Entente is a faction that can be formed by France with the 'Little Entente' National Focus. When this faction is formed, France won't join the Allies. Based on the real life alliance with the objective of preventing Hungary rearming and/or a Habsburg restoration in Austria.
- Possible members
Active with Poland's unique focus tree available through the free DLC with the 'Between the seas idea'. It will be formed by Poland and can be expanded to include the Baltic states. The faction has bases on the historical idea of the Intermarium, in polish Międzymorze, a plan created by politician Józef Piłsudski in which the eastern European countries that broke free from Russian control would create a federation between the Baltic and Black seas. In the game, however, the Międzymorze is only a military alliance.
- Possible members
Northern Sovereignty CoalitionEdit
( Together for Victory) If Canada chooses to become independent from the United Kingdom and become fascist it can either join the Axis or support fascism in Mexico and create the Northern Sovereignty Coalition. Doing this can give a favourable outcome in a war with the United States.
The South-West Pacific InitiativeEdit
Western Pacific SphereEdit
African People's UnionEdit
( Together for Victory) An independent, communist South Africa can form this faction. It has no default members and will have only South Africa at the game start, however, they can conquer colonies from Portugal; Belgium; United Kingdom and create puppets.
- Possible members
If the Little Entente has not been created but France backs Czechoslovakia in the Sudetenland crisis (or Yugoslavia in the ahistorical Slovenia crisis), and Britain does not, then France will create a faction called the French Alliance, and invite Czechoslovakia/Yugoslavia.
Pan-Slavic Worker's CongressEdit
( Death or Dishonor) If Yugoslavia becomes communist, it can invite Bulgaria and Albania into this faction. It should be noted that Albania isn't a Slavic country, although former communist head of state Enver Hoxha did fear a Yugoslavia annexation.
Pact of RomeEdit
Central European AllianceEdit
( Waking the Tiger) If Germany chooses to oppose Hitler and reestablish democratic elections, it will eventually create the Central European Alliance in opposition to the Soviets and eventually offer membership to a number of non-fascist, non-communist countries across Europe. Potential members include Austria, Czechoslovakia, Hungary, Yugoslavia, Romania, Netherlands, Belgium, Luxembourg, Norway, Sweden, Denmark, Estonia, Latvia, Lithuania, Poland, and Finland.
( Waking the Tiger) If Germany chooses to oppose Hitler and reestablish the German monarchy, then it will form this faction and attempt to restore Austria-Hungary and reestablish monarchy in Italy. The German Empire in this case will very likely attempt to regain its 1914 borders while Austria-Hungary will be going after its old imperial possessions in central Europe ( Czechoslovakia, Hungary and parts of Yugoslavia). All other Non-Aligned nations in Europe are eligible candidates for membership.
Mutual Assistance BlocEdit
( Waking the Tiger) If Communist China decides to go down the "Agrarian Socialism" route of its focus tree, they will eventually create this faction. Potential members are any communist nation in China, like Sinkiang.
If the Soviet Union attacks a signatory of the Anti-Soviet Pact, Germany can create a faction of the same name.
Government of National DefenseEdit
The New InternationalEdit
The Old AllianceEdit
( Waking the Tiger) If after Japan completes the focus "Rekindle the Old Alliance" the United Kingdom is not in a faction or not democratic, Japan will form this faction and invite the United Kingdom.
The People's FrontEdit
( Waking the Tiger) If the Soviet Union decides to support a warlord, Communist China doesn't accept defeat and they are separated by another country (typically Xibei San Ma), that country may support Communist China and form this faction.
Union of Communist SovietsEdit
West Pacific Treaty OrganizationEdit
Treaty of Reciprocal AssistanceEdit
British Communist AlternativeEdit
Commonwealth of NationsEdit
Community of NationsEdit
