"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! Originally thought up by Sarmatia in 2005, the mod has since developed into one of the most in-depth alternate history mods, with thousands of new events, new graphics, new countries and even new mechanics! Rewrite history (again), but this time in Hearts of Iron IV!
So onwards all and enjoy!

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.

Loading the game with Kaiserreich enabled causes a crash with a file exception error in the D:\jenkins\workspace\HOI4-Live-R-Stream-Windows\clausewitz_hoi4\pdx_core\virtualfilesystem.cpp. If anyone could tell me what exactly that means and how I could fix it I'd much appreciate it.

They broke up the 0.7 so South America could be focused on, cleaned up of bugs and then for them to progress to North America. Canada won't be part of the fix to North America, but they may add in features.

What can we be expecting with the next update? I've heard some talk about North America, and if that's the case, what can be expanded on? I mean, Canada was pretty fun to play and so was the U.S.A with it's civil war. So, what's next?
