Madame de Nemours had amongst other possessions the sovereignty of Neufchatel. As soon as she was dead, various claimants arose to dispute the succession. Madame de Mailly laid claim to it, as to the succession to the principality of Orange, upon the strength of a very doubtful alliance with the house of Chalons, and hoped to be supported by Madame de Maintenon. But Madame de Maintenon laughed at her chimeras, as they were laughed at in Switzerland.
M. le Prince de Conti was another claimant. He based his right upon the will of the last Duc de Longueville, by which he had been called to all the Duke’s wealth, after the Comte de Saint Paul, his brother, and his posterity. In addition to these, there were Matignon and the dowager Duchesse de Lesdiguieres, who claimed Neufchatel by right of their relationship to Madame de Nemours.
Matignon was an intimate friend of Chamillart, who did not like the Prince de Conti, and was the declared enemy of the Marechal de Villeroy, the representative of Madame de Lesdiguieres, in this affair. Chamillart, therefore, persuaded the King to remain neutral, and aided Matignon by money and influence to get the start of the other claimants.
The haughty citizens of Neufchatel saw then all these suitors begging for their suffrages, when a minister of the Elector of Brandenbourg appeared amongst them, and disputed the pretensions of the Prince de Conti in favour of his master, the Elector of Brandenbourg (King of Prussia), who drew his claim from the family of Chalons. It was more distant; more entangled if possible, than that of Madame de Mailly. He only made use of it, therefore, as a pretext. His reasons were his religion, in conformity with that of the country; the support of the neighbouring Protestant cantons, allies, and protectors of Neufchatel; the pressing reflection that the principality of Orange having fallen by the death of William III. to M. le Prince de Conti, the King (Louis XIV.) had appropriated it and recompensed him for it: and that he might act similarly if Neufchatel fell to one of his subjects; lastly, a treaty produced in good form, by which, in the event of the death of Madame de Nemours, England and Holland agreed to declare for the Elector of Brandenbourg, and to assist him by force in procuring this little state. This minister of the Elector was in concert with the Protestant cantons, who upon his declaration at once sided with him; and who, by the money spent, the conformity of religion, the power of the Elector, the reflection of what had happened at Orange, found nearly all the suffrages favourable. So striking while the iron was hot, they obtained a provisional judgment from Neufchatel, which adjudged their state to the Elector until the peace; and in consequence of this, his minister was put into actual possession, and M. le Prince de Conti saw himself constrained to return more shamefully than he had returned once before, and was followed by the other claimants.
