In this mod, you will be able to experience interesting scenarios, such as the War of the Spanish Succession and the Great Northern War, famous for the legendary campaigns of Charles XII otherwise known as Carolus Rex. Whilst the combat of HOI4 would normally not make a lot of sense for a scenario in the early 1700s, the mod aims to bring a genuine ancient regime feel to the game, introducing retextured technologies, hundreds of unique portraits, a dozen new focus trees and many other events and national spirits.


Whilst Empire has been in the making for quite some time, work is never truly finished. This mod has been a mostly solo project for the last two years, but I can assure you that progress is being made every single day to make this mod into the ultimate 1700s experience.

“Help, the mod doesn’t work!”

Since 1.8 the new official Paradox launcher is known to have some serious issues with loading mods, often messing with the ‘descriptor file’. This is an issue that can unfortunately not be fixed until Paradox fixes their stuff, but generally reinstalling the mod, or simply reloading the launcher should do the trick.


“Help, the mod has crashed!

Crashes are quite rare in Empire, but they can happen. Most commonly, the game tends to freeze during a peace conference. In 99% of the cases, it get’s resolved by just waiting. To my personal experience, in the scenario where your game crashes, simply reloading your latest game always works without issues.
