I think there's already something like this on Reddit, but I want to make this anyway. These will be released more as an analysis on what happened to each nation during and after all four (so far) games. I'm starting with this.
4000 BC: Four great empires: the French, Venetian, Shoshone and Ethiopian Empires, are founded.
2000 BC: After numerous bids for renaming Moson Kahni, with possibilities such as River Place and Place Where Man He Put Bucket On Head, the Shoshone capital is renamed Mango Peepee. The Venetian capital Venice, meanwhile, is renamed Sandland, for the vast expanse of desert surrounding it.
1000 BC: Construction of the Pyramids is completed in Paris, France.
300 BC: The French city of Troyes is founded in the shadow of Uluru.
500 AD: The Ethiopians found the religion Eastern Orthodoxy.
550 AD: Holy Frenchism is founded in the holy city of Paris. It begins spreading to the four corners of the world.
700 AD: French Emperor Lewis I proposes the founding of a French city right outside Sandland. After the border disputes with the Shoshone over the city of Novenice Dogesu, Venetian King Duncan refuses, and the French Army mobilizes and goes to war.
1000 AD: The Venetian Empire falls to French domination as Robert E. Lee leads the Grande Armée to victory in Sandland. King Duncan is taken into French custody, and after surrendering at the point of a spear, he is suffocated to death when a baguette is forcibly shoved down his throat by French Emperor Lewis himself. In light of the successful invasion, the Shoshone back down and accept unquestionable French hegemony.
