The French state declared bankruptcy in 1788 and it was a slow motion disaster. The calling of the Estates General to agree a new constitutional settlement was not the Crown’s preferred way of dealing with the necessity to share more power to get agreement to pay more taxes but they knew a new constitutional settlement was going to happen. The last attempt to keep things somewhat under royal control was the 1787 Assembly of Notables[1]. But even then it was obvious that there was going to be a radical change in government. A great deal more democracy was going to arrive in France, 25 years of war in Europe or no.
