An idea that I had rolling around in my head from this thread
The national anthem of France - The song of Marseilles 'La Marseillaise' (even though apparently it comes from near Strasbourg) has become famous as a rousing call to arms "allons citoyens, formez battalions!" for instance. And yet, to my knowledge, besides the brief July Monarchy stint, after Napoléon I had it replaced with "Salut au Veillons" until well after the Paris Commune (1879), the anthem was banned.
What if the royalists had adjusted the lyrics somewhat, by toning down the republican polemic, and then adopted the anthem on Louis XVIII's restauration after the 100 Days?
