List of Nations, Tribes, and Empires

Nations, otherwise known as Tribes or Empires, are the acting entities of Hearts of Iron IV. Each is controlled by a player or by AI and pursues its own national focus tree during a game as well as choosing various political Ideas, engaging in Diplomacy, Construction, Research, Production, and the command of its military units.

Each country belongs to one of four political Ideologies, which can change over a game, though there are in most cases no ways to increase the Non-Aligned ideology without modding.

Major Nations
Nations in HOI4 are either major nations or minor nations. In a war, a faction will only surrender when all its participating major nations capitulate. Major powers refer to ones with the highest number of factories, within the top 7 or 70% of the average of the top 7, updated monthly. Nations cannot lose their major status while at war.
