Crown of Illyria
伊利里亚的王冠
About this mod Machine translation
A mod I made for myself. Contains primarily Croatian content, a formable Illyrian Empire (ILY), as well as Adriatic/Balkan region situations, disasters, events, situational actions, reforms, progression, units, modifiers and related settings. (With the help of AI)
Feedback would be greatly appreciated, this is my first mod.
content
Government Reforms: 4 Croats - 6 Illyrian Empires
Country Progress: 15 Croatian Themes - 45 Illyria
Unique buildings: 5
Units: 3 Croatian Army - 22 Illyrian (13 Army/9 Navy)
Events: 41 (32 Croatian chains + 9 Illyrian empires) - 10 reforms - 13 Croatian disasters - 10 Illyrian disasters - 31 situational events - 105 total scripted country events
Update May 17, 2026: Made many new events for Illyria, reworked many Croatian events, added bureaucracy to the Illyrian Empire, and applied the Phoenix's fate mechanic to the Illyrian Empire.
New situation:
Illyria Overextension - Triggered when ILY's stability and legitimacy is low, war fatigue, core control is weak, or the ruler is uneasy. Neighbors can apply timed "pressure" debuffs within a fixed radius; you need to pay to remove these debuffs.
Battle for Illyria - When Croatia and Serbia were contenders for independence (Bosnia, Albania and the holders of the Albanian region were also among them). Situational actions and events drive the fight to unite the region under one crown; this can end when an ILY is formed, Croatia's relationship with Hungary is as defined by the mod, or after a long timeout.
Battle for Dalmatia - Coastal Croatia faces competition from Venice (CRO needs to compete with Venice). Croatia won by controlling Zadar, Split and Dubrovnik. Venice wins by controlling Kenin and Senye (if Venice exists). Otherwise, the situation could end in 100 years.
Illyricum's Religious Front - Active when an independent Christian ILY (or any Illyrian subject) borders a level 2+ Muslim nation. Ends when this border situation clears; can be restarted at a later date (based on the usual monthly generation roll) if the border reoccurs.
New Disasters: • Rupture of the Illyrian Crown - One-time crisis for ILY: weak core, war stress, or disloyal subjects; heavy fines on the palace and estates until conditions for restoration are met. • Crisis of the Croatian Crown - A one-off crisis for the Kingdom of Croatia: disputed crown within the Hungarian Union or within the country; facing pressure on stability and legitimacy until final inspections are completed. Should be compatible with version 1.2.
Install & use Install: follow the bundled instructions
- Unzip the archive from playbuff and read the bundled readme / instructions first.
- There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
- Place the files exactly as the readme says; mods with listed dependencies need those installed too.
- Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.
Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
