Creation of a new alliance

The file governing starting alliances are found within history\diplomacy. You are looking for the "alliances" file.

Each relationship has four informations:

  • first =
  • second =
  • start_date =
  • end_date =

It does not matter, which country tag you put in first and which you put in second. The start date should be before the intented start date. Any date before 1836.1.1 is just for flavour, but if you intend the alliance to only count for the American Civil War scenario, use 1861.1.1 instead. The end date does not have an effect, so just use 1936.1.1.


alliance = {
first = PEU
second = BOL
start_date = 1836.1.1
end_date = 1949.1.1

This case creates the starting alliance between Peru and Bolivia.
