De Maistre to Blacas, quoted by E.
In 1810 his wife died, and in 1811 d'Avaray died, his place as favourite being taken by the comte de Blacas.'
His concessions to the reactionary and clerical party of the emigres, headed by the comte d'Artois and the duchesse d'Angouleme, aroused suspicions of his loyalty to the constitution, the creation of his Maison militaire alienated the army, and the constant presence of Blacas made the formation of a united ministry impossible.
After the Hundred Days, during which the king was forced to flee to Ghent, the dismissal of Blacas was made one of the conditions of his second restoration.
An attempt on the part of the Ultras to regain their ascendancy over the king, by conniving at the sudden return of Blacas from Rome to Paris, 3 ended in failure.
His position was more passive than active, and consisted in giving his support as far as possible to the 1 Pierre-Louis-Casimir, comte (afterwards duc) de Blacas d'Aulps, was as rigidly royalist as d'Avaray, but more able.
3 It is as yet not proved that Blacas returned from his embassy in response to a summons from the Ultras.
