Historical Project Mod

For Hearts of Iron IV

Inspired by the Victoria II mod of the same name, the Historical Project Mod (HPM) for HOI4 seeks to enhance the vanilla HOI4 experience by adding and tweaking historical events, decisions, and focuses without disrupting the core experience as designed by Paradox.

At the moment, HPM for HOI4 is basically a vanilla+ mod, rather than a full overhaul. Expect this version to be pretty close to vanilla but with some tweaks and a few new events. If you find any bugs while using the mod, please report them to me. Also, going down alternate history paths may break certain features as those things haven't been tested.

• Basic focus tree for Brazil
  
• Synthetic fuel refineries are 2x more powerful to compensate for Germany being cut off from Middle Eastern oil
  
• The 1941 Iraqi coup d'etat

• Free City of Danzig under British, French, and Polish protection
  
• German-Polish Non-Aggression Pact in place at game start

• Other minor diplomatic relations additions to better reflect the geopolitical situation in 1936
