 Form Irish Nation

For decades England has attempted to subjugate the Irish population and take control of the island. To unite the Irish lands under a sole flag may be our only chance to repel them.

Potential requirements

  Ireland does not exist.
The country:

If the country is AI-controlled,

  • it can not be a custom nation.
  • it can not be a former colonial nation.
  • it must have at least 3 cities.

The country:


The country:

  • changes to   Ireland.
  • gets   kingdom rank if the country is duchy rank.
  • gains  10 prestige.
  • gets the modifier “Increased Centralization” for 20 years with the following effects:
    •   −0.05 Monthly autonomy change
    •   +1 National unrest
  • removes all its provinces from the HRE if it is a member of the HRE but not the emperor or an elector.
  • gets the   event ‘New Traditions & Ambitions’ if it does not have custom ideas.


Offaly is a difficult nation to play as, because as soon as   England has recovered 60% of its manpower, it will gain claims on all of Ireland. This will usually happen after the initial Surrender of Maine and war with France and after the war of the roses.

Initially there are two different choices. Try to stay in Ireland or try to flee to the new world. If you plan on staying in Ireland, prioritize annexing as many Irish provinces as possible and chose military ideas. If you plan to flee to the new world, take colonization ideas, discover America, and colonize less than five provinces in a colonial region. This is very important, as otherwise, it will form a Colonial Nation.

For the Spanish Fly achievement, forming Ireland or any other tag will not prevent the achievement, but instead only hide its conditions. The easiest way to get it is to take a single province from Spain with another tag's core (e.g. Asturias), release it as a vassal, use the "place dynasty on throne"   subject interaction, annex them, return their core via the province button, claim their throne, and declare war with restoration of the Union CB and enforce the union.


Own and have cores on the British Isles as an Irish nation.
Starting as Offaly, secure a Personal Union over an Iberian nation.
