Formable countries
- See also: Formation decisions
A formable country is one 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. A reformable country is one that does start as an independent nation but if it ceases to exist, then other countries with similar culture may transform into it, adopting their flag, ideas, and identity. All the relevant formation decisions can be found in their respective country pages (unless otherwise stated). Generally, a nation must meet the following requirements to form most formables:
- Target formable does not exist
- At peace
- Admin tech level at least 10
- Is not a non-tributary subject
- Is not a Steppe Horde
- Own and core certain provinces
- Some provinces can also be owned by non-tributary subjects

Former colonial nations[edit]

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. Around half of 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.
Pirate nations[edit]
Some pirate nations (except for 
Tétouan who has a core in the 1444 start date and 
Palembang, 
Pattani or 
So which are playable in the 1444 start date) can only appear via special event which allows the player to either: to release said country as an independent nation, release it as a march, or play the country as a newly released independent nation.
Reformable countries[edit]
The following nations exist at the 1444 start, but can be reformed by other nations if they cease to exist:
End-game tags[edit]
Some countries are end game tags. These countries are not allowed to form other countries even if they otherwise meet the prerequisites.[1] Three exceptions are the last imperial reform creating the Holy Roman Empire, the Roman Empire restoration decision, and Yuan forming the Mongol Empire. However, you cannot restore the Roman Empire as the Holy Roman Empire or the 
The Papal State. The end-game tag restrictions can be lifted by disabling the option Limited Country Forming.
German regional tags[edit]
Some countries are German regional tags. These countries are not allowed to form other German countries even if they otherwise meet the prerequisites.[2] The decision to form Prussia is the only one of these that does not exclude German regional tags, so Prussia can be formed by the other nations on this list, but Prussia itself can't form the other countries.
Effects of formation[edit]
- 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 do not get the event this way.
- Formation of a new country changes "historical rival" attitudes regarding other countries. For example, if Christian
Ottomans form Roman Empire, they will no longer be historical rivals with 
Austria. This also applies inversely; if 
Burgundy form 
France, they will become historical rivals with Austria. - Although 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 the 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. - Nation formation and reformation can form part of a strategy for reducing core creation cost. Permanent claims given by formation decisions give valuable bonuses such as −25%
core creation cost and casus belli over a large area. Moreover, re-forming a destroyed nation allows cores to be conquered for no administrative power or diplo-annexed for no diplomatic power. - Forming another nation while being the
Emperor of China resets all reforms made as the previous nation. This is important to keep in mind if looking to form Qing or Yuan.
