[1.13]Ultra Historical Diplomacy
This mod aims to rebalance Diplomatic Interactions, Infamy, AI Diplomacy and Major Unifications.


Ultra Historical Diplomacy is the fourth mod of the Ultra Historical mod series.

- Quinine technology delayed to Tier 3
- Treaty Port war goal can only target unrecognized polities and colonial affairs institution is required to add it as wargoal
- Colonial Exploitation law requires Civilizing Mission technology
- Set initial colonial claims in Indonesia and Algeria
- Interrest tiers made more restrictive, so players must build more involvement before doing aggressive moves.
- Oregon Dispute Journal Entry reworked
These changes restricts heavily early colonisation, using existing vanilla system.
With this system, "Colonial Ressetlement" law represents earlier stages of colonial Empires. "Colonial Exploitation" law represents the real push for colonies in Africa and Asia.
Combined with a later access to Quinine, it leads to colonization occuring roughly within the historical timeline.
The restrictions on things you can do on lower interest tiers also forces to actualy be more "involved" in an area to justify its eventual conquest.

- Scandinavia is no longer a Major Unification, but a normal one
- Italian Unification rebalanced
- German Unification rebalanced
These simple changes makes Major Unifications more logical.
Scandinavian unification was never really a strong desire in modern history, so it was replaced by a normal one. Still accessible but lose the Major Unification mechanisms.
For Germany and Italy, the numbers of required states were adjusted so both can be formed with the states they historicaly had.
Extra conditions were added for countries that were historicaly against the very concept of German/Italian unity.
So Austria and Two-Sicilies cannot form Germany/Italy as easily as Prussia and Sardinia-Piedmont, unless they get radical political changes before.

- Max infamy from target’s population increased
- More infamy is removed when a wargoal is not enforced
- Taking homelands generates less infamy
- Reduced infamy taken by conquering unrecognized polities, especialy after Colonial Exploitation is activated.
- Conquering bigger unrecognized polities like Japan and Persia generate more infamy than conquering smaller ones
These changes makes conquest between recognized countries way more punishing, especialy for Great Powers, unless they get claims or target their own homeland / unify their nation.
It roughly represent early international order (Concert of Europe) and also discourage AI countries for mad conquest spree.
Conquest of minor unrecognized polities on the other hand generates very little infamy, allowing a proper colonial scramble once you get colonial exploitation law.
Conquering higher ranked unrecognized countries still generate enough infamy to punish a player/AI wanting to take a slice of Japan or puppet Persia, representing the fact those countries were partialy "recognized" as civilized nations.
Of course, a super aggressive player can ignore infamy system altogether to go for unlimited conquests, making all diplomacy irrelevant, this is not an encouraged behaviour for the loss of immersion and gameplay it causes.

– French
– German
– Spanish
– Portuguese
– Chinese (separated submod)
We plan to improve whatever new diplomatic feature Paradox is gonna implement in the future.
The game is currently missing some diplomatic aspects, yet we don’t plan to add heavily scripted systems (like Conference of Berlin, Concert of Europe, etc.) since those are in the scope of our brewing Flavour Mod.
