Adrienne de Lafayette died on December 25, 1807, after years of impaired health following imprisonment during the French Revolution. She had survived the Terror, when several close relatives were executed, and later voluntarily shared her husband's confinement at Olmütz with two of their daughters. The conditions of that imprisonment damaged her health, and accounts say that she never fully recovered. After release she returned with the family to France, where her later life centered on the household and the effort to restore a measure of stability after prolonged political upheaval. Her final decline is linked in the biographical tradition to that earlier suffering, but the material consulted does not establish a precise modern diagnosis or a complete sequence of symptoms and treatment. It would be misleading to convert the general connection with imprisonment into a confirmed specific infection. Her husband survived her, and she was buried in the Picpus Cemetery, where members of her family killed during the Terror also lay in a mass grave. Those associations explain the emotional and historical setting of the burial. Her own death, however, followed a prolonged failure to regain health rather than execution. The exact final medical mechanism and bedside exchanges remain less securely documented than the course from imprisonment to continuing frailty and death in 1807.
