Marie De Rohan Montbazon Chevreuse, duchess de, a French woman celebrated for her beauty, wit, and intrigues, born in December, 1600, died at Gagny, near Chelles, Aug. 12, 1679). When scarcely 17 years old she married the duke de Luynes, grand constable of France, who died four years afterward. She next became the wife of Claude de Lorraine, duke de Chevreuse. A great friend of Anne of Austria, she incurred the hatred of Richelieu, and became so obnoxious to him that he determined to have her arrested; but, made aware of his project, she assumed man's attire, crossed the Somme by swimming, and tied to England. For years she was an exile from France, and Louis XIII. had been inspired by his minister with such fear of her uncontrollable spirit and cunning, that in his will he forbade her return to France. Anne allowed her to return, however, but the queen's coldness induced the duchess again to leave the court. Afterward she engaged in new plots against Mazarin, mostly acting in concert with the cardinal de Retz, and was once more compelled to leave France. Her intriguing spirit outlived her beauty, and she wandered through the Netherlands, Germany, and England, still plotting against her enemies.
