The first thing that happened is that the Crown went bankrupt and its authority disappeared. The King needed to regain legitimacy and for that he needed to share power more broadly. France had a growing ambitious bourgeoisie who was largely shut off from power and wouldn't let this opportunity slip.

The King lost control of the reform process but he was still a convenient lynchpin of the Constitution, which still gave him extensive veto powers.

The French were the ones to declare war on Austria, it's interesting to think of an alt history where cooler heads prevail and focus on internal regime consolidation rather than chasing the reactionary émigré nobles.

It's still a very difficult environment for the Revolution, after all the Austrians might end up declaring war themselves anyway.

@DiegoBeghin These kind of analyses are super interesting.

We see the revolutions of 1848 as mainly having been failures, but they actually democratized huge parts of Central and Eastern Europe's populace, and further catalysed the democratization process in France, Benelux, and Scandinavia. (I wrote my BA thesis on this).
