A formable country is a country that does not exist at the beginning of the game (although it might in later historical starts) but can be formed if certain conditions are met. All the relevant formation decisions can be found in their respective country pages (unless otherwise stated).
All of these formation decisions require that the game is using the historical setup.
- Golden Horde
- Great Britain
- Holy Roman Empire
- Roman Empire
Former colonial nations
The following nations can only be formed by former colonial nations who have achieved independence. Unlike other formable nations, these can be formed in games using the random setup. A country can only form one of these nations during a scenario. Except for Brazil, Canada, Mexico, Quebec and the United States, these nations don't have unique ideas or events, so the formation decisions are mostly cosmetic, although they usually provide prestige and permanent claims on their respective regions.
The following nations can be reformed by other nations if they cease to exist.
Effects of formation
- Most formable countries have unique national ideas. An event triggered by the formation decision gives a choice between switching ideas or keeping the existing set. Note that custom nations cannot change ideas this way.
- Formation of a new country removes "historical rival" attitudes regarding other countries. For example, if Christian Ottomans form Roman Empire, they will no longer be historical rivals with Timurids.
- Although the diplomatic relations (alliances and rivalries) won't change, the attitude of other non-rival countries will temporarily become "unknown" (for a month or so). This can cause an ally to announce newly formed country as rival, if this ally is below the rivals limit. For example, if Morocco is allied to Granada and has fewer than 3 rivals, and Granada forms Andalusia, then Morocco will immediately rival Andalusia upon formation.
