Nicolas de Saulx-Tavannes was born on 19 September 1690 in Paris to Charles-Marie de Saulx de Tavannes, Count of Buzançais, Marquis of Tavannes, and Marie-Catherine d'Aguesseau, Lady of Lux. He was the nephew of the
Chancellor d'Aguesseau and the cousin of the
Cardinal de Gesvres. Appointed
Bishop-Count of Châlons-en-Champagne by the Duke of Orléans, regent of the France, he was consecrated on 9 November 1721 at the
Theatines church in Paris by
André-Hercule de Fleury, former bishop of Fréjus, assisted by François-César Le Blanc, bishop of Avranches and François Honoré de Casaubon de Maniban, bishop of Mirepoix. He therefore became a
Peer of France. He was created Cardinal-priest during the
consistory of 5 April 1756 held by
Pope Benedict XIV. The Pope sent him the red bar with an apostolic brief dated 7 April 1756, but Nicolas de Saulx never went to Rome to receive the red hat and did not have the title of cardinal. He also did not participate in the conclave of 1758 which elected
Pope Clement XIII. He died on 10 March 1759 in Paris and is buried in the
Saint-Sulpice church without having a funeral memorial. == References ==
