In July, 1746, Philip V. of Spain died; and the event was followed immediately afterwards by the death of his daughter, the Dauphine of France. The new king, Ferdinand, was strongly desirous that the young French prince should espouse the sister of the late Dauphine; and the proposal was supported by a powerful party at the French Court, at the head of which were Noailles and Maurepas. The project was distasteful to Louis XV., and it was rejected, ostensibly upon religious grounds. It is suggested that d'Argenson's qualms were occasioned, not by an access of unwonted scrupulosity, but by the hope of repairing the disaster of Turin by the betrothal of the Dauphin to a daughter of the King of Sardinia.[367] Louis was favourable to the scheme, and negotiations were actively begun; but the determination of Sardinia to press her advantage in Italy led to their suspension. It was then resolved to demand in marriage the daughter of Augustus III. of Saxony. The enterprise proceeded with singular rapidity, and d'Argenson is proud to record it as the most striking of his diplomatic successes. Yet on the very day on which the marriage was celebrated at Dresden, the apparent author of it was disgraced. The reason is as remarkable as the fact itself. Throughout the negotiation there were two policies at work, one of which was entirely unknown to the French minister. D'Argenson had conceived certain bold and statesmanlike views with regard to the position of Saxony. He hoped to bring about an understanding between Saxony and Prussia, and by the combined influence of France and Prussia, to make the crown of Poland hereditary in the Saxon house. By so doing it might be possible to withdraw Augustus III. from his blind dependence upon Vienna and St. Petersburg. The first step in the realisation of this plan must be the ruin of the Saxon minister, Count Brühl, a sworn partisan of Austria. The other policy was that of Count Brühl himself. He proposed to take advantage of the French overtures in order to bring about an understanding between France and Austria, and so to use their combined forces for the destruction of the rising power of Prussia. The first step in furtherance of the scheme must be the ruin of the Marquis d'Argenson, a firm ally of Prussia.
