Since France is a monarchy again any chance of the white orleans banner, suplimenting the tricolor?
I'm so sorry, I wanted to expand on this a bit more, but was pressed for time. Right, so, after doing some basic research, I believe I know why the flag of France in TL-191 starting in 1931 is the way it is.
^^^ --- This particular flag is very representative of France in a way, especially in regards to French royalty and catholicism. The symbol of the Fleur-de-lis, as well as the colors of blue and yellow, are also used by the political faction Action Francaise. So, more than anything, this flag may be more representative as the political party's flag. They are far-right French nationalists that support a return of the monarchy in France --- but it should be noted that it seems they were
not in favor of a return of an
absolutist Bourbon monarch. And that's an important distinction to make in this case, especially in the case of France.
It seems that Action Francaise was primarily a pro-Orleanist faction. The Orleanists, way back in French history after the Napoleonic Wars, were in favor of a restoration of the monarchy, but as a
constitutional monarch, with the ideal candidate coming from the House of Orleans, with the king acting as a kind of political rallying point to steer the parliament in a general direction. A good example would be King Louis-Phillip I from 1830-1848.
The Orleanists, and by extension the House of Orleans, were very opposed to the the idea of a complete Bourbon restoration which was advocated for by the Legitimists --- supporters that were equally far-right, yet very ultra-royalist. The Legitimists wanted to completely restore the Ancien Regime of France --- that is to say they wanted the complete restoration of absolutism in France it seems, with all the privileges it allotted to the nobles. As such, they supported the House of Bourbon. Their primary colors to distinguish them were blue and white.
Its also important to note that both Legitimists and the Orleanists were passionately opposed to democracy and especially
republicanism in France, which they saw as a corrupting element to the country. Likewise for Action Francaise, they too would be opposed to this in their own way, since they advocated heavily for the return of a monarch.
And I think this is an important distinction to make. If the monarchy truly did return to France, it would be represented by the flag as well, but it would be important to the French as to which faction that supported monarchy was in charge. If their was a Bourbon on the throne, then the flag would very likely be the white flag.
But it this case its the flag of Action Francaise, a very pro-Orleanist faction, which would likely not raise the white flag that is so representative of the Bourbons, which they opposed.
Again, could be wrong on all of this, but I thought it was fascinating to learn.
