As a member of the royal military the Duke was away from his estates during much of the
French Revolution and was not present for the death of his father, upon which he became the
Duc de Noailles. His absence spared him being arrested along with most of his relatives on orders of
Robespierre in May 1794. On 22 July that year, his 70-year-old mother (the dowager Duchess Françoise de Noailles), his wife (the
Duchess Anne-Louise-Henriette), their eldest daughter Louise (the Vicomte de Noaille, by virtue of marriage to her cousin
Marc Antoine de Noaille), and their second daughter,
Adrienne de La Fayette, were condemned to the
guillotine. All were executed except for Adrienne, who was spared at the last moment due to intervention by the future American president,
James Monroe (the then
U.S. Minister to France), because of her husband's efforts for America during the
American War for Independence) but only after her paternal grandmother, mother, and sister were beheaded within her sight. The Duke learned of their deaths weeks later. His family had lost many other members including two of his uncles (including
Philippe de Noailles, duc de Mouchy) and numerous cousins and in-laws during the Revolution. The Duke went into self-imposed
exile in Switzerland until the Bourbon Restoration, returning to France and his ravaged estates after
Napoleon and
the Directory restored some order. Through the efforts of his daughter Adrienne de La Fayette, whose husband's family also suffered greatly in the Revolution, some part of his once immense fortune was restored. ==Personal life==
