Like many other ATL, this takes place starting at Napoleon's time. What would have happened if he was victorious? How would this affect the rest of the world.
Instead of attacking Moscow in Winter, Napoleon had engaged a slower campagin, eventually taking the Russian capital in the following summer. The great country of Russia was then split into two rump states, Moscow, controlled by the royal family, and Ivanstead, a French-influenced democarcy, heavily controlled by the Napoleonic party.
Afterward, Napoleon would attack Great Britain, defeating the once mighty Empire once and for all. This would have grand consequences upon the Eurpoeon World, and even the Americas overseas.
