Cellamare conspiracy

The Prince of Cellamare and his embassy wanted to depose Philippe d'Orléans and make Philip V the Regent for his nephew.

The plan was greatly supported by some of Philippe d'Orléans's most notorious enemies, namely Louis Auguste, Duke of Maine and his wife, Louise Bénédicte de Bourbon.

The baroness's memoirs said that the duke and duchess of Maine had wanted to call a meeting of the États généraux on the matter.

The Duke of Richelieu was imprisoned in the Bastille where he was later visited by his lover, Charlotte Aglaé d'Orléans, dressed in disguise.

On 9 January 1719, France declared war on Spain, following in the footsteps of Great Britain who had done so a couple of weeks earlier, on 27 December 1718.
