Imajin, what is the fourth empire on your map, the one in North Africa?
Well, don't get your hopes up on it being a North African superpower- It's actually Austrian North Africa, though Austria is having one heck of a time holding it down. After the Great War breaks out, it basically gives up control of the region. However, later in the TL that massive territory in Asia becomes a world power..
The Four "Empires" are Prussia (A Kingdom, but it has one of the strongest militaries in the world so they don't care), Austria (Which has done a good job keeping it's minorities down in this TL, and actually has most trouble with Pan-Germanism), Russia (Most powerful nation in the world at this time), and America (Also powerful, but democratic rather than the more common Autocracy)
