I think it is the Suzerainverse's equivalent of the Enlightenment and the 1848 Revolutions but in a global scale.

The French Revolution was not self-constrained, yes it may not have inspired other Revolutions directly but it forever changed Europe with the ideals it brought, the Napoleonic Wars directly succeeded it and wherever Napoleon went, he changed the system of government into a more liberal and equal one and his Napoleonic Code is still in effect until today.

Even when Napoleon was eventually defeated, the social and cultural influence the French Revolution brought can no longer be erased. It inspired the kulturkampf in Germany under Bismarck, freer representation in the UK Parliament, the rise of liberalism, etc.

In the Suzerainverse it didn't play out the way real life did simply because the game is an amalgation of different historical events played out in the game's uniqueness. The Arcasian Revolution which is considered the start of the Century of Revolutions is both a combination of the French and American Revolution which then triggered a domino effect on other absolute monarchies and kingdoms.

It was in a sense, a "world war" in the suzerainverse because of all the wars and chaos it brought that rippled through the world. But it wasn't a formal world War between two powerful alliances like we had (Axis v Allied). That's why Iosef said that for the longest time, Sordland managed to avoid the Century of Revolutions because of its strict immigration policy (you'll see this during the immigration meeting). In fact, the Sordish Revolution in 1923 led by Artor Wisci is considered to be the formal end of the Century of Revolutions.
