This is my first ever Wiki post, apologies for any inaccuracies or procedural errors.
As far as I can see, and I'm NOT an expert in the field, the material seems factually accurate.
However, the English used in some sections seems quite poor.
The section titled "The diet of Besançon and the first differences" seems to need a re-write, as it contains some run on sentences and the like.
Also the opening section could use a better introduction, perhaps a very brief description of historical context, European powers and united modern states of the period, (If any) and an introduction into "The Imperial Idea".
All in all though, as far as I can tell, it is factually accurate.
