"What if Germany had won World War 1?"

The Kaiserreich 4 Team are proud to announce that the most popular alternate history mod for Hearts of Iron II & Darkest Hour has now come to Hearts of Iron IV!

The Hearts of Iron IV version of Kaiserreich is still in alpha and yet it already contains thousands of events and dozens of focus trees so inevitably there will be mistakes, please report them here: https://github.com/Zankoas/kaiserreich/issues?utf8=%E2%9C%93&q= in as detailed a way as possible. Please don't report them anywhere else, it makes our lives much easier when all bug reports are in one place.

Unofficial, though with our support, translation efforts are under way in many languages. Help is wanted for all teams and we would love to open new teams as well.

Is it just me or Mongolian focus tree breaks if Ma Clique accepts to become your puppet? Cause I can't annex them and any other conquest foci require Ma Clique to not exist.

That is a Change.
For Austria Dualism Restored doesn't do anything and neither does the ones above it. Has this changed since the last version, since I used to remember them uniting all the puppets?

@The Fighter Pilot
you almost assuredly have a mod that does that, say the black and white mod
