The challenge is to create a PoD that leads to France being the premier European empire by 1900. Simply put, France must be in the role that England was OTL by this time, and must have an empire of similar or larger size than England had in 1900. The PoD may be at any point in history and be whatever sort of event desired so long as it leads to the required outcome in a plausible manner.

Bonus points: If you think you can, try to complete this AHC using Sweden, Denmark, Norway, or Germany instead of France, without being overly implausible.
