Léon Bouthillier, comte de Chavigny

Léon Bouthillier, comte de Chavigny (March 28, 1608 – October 11, 1652) was a Foreign Minister of France to Louis XIII.

He was associated with his father, Claude Bouthillier, who took him to all major courts of Europe, tutoring in diplomacy, from 1629 to 1632.

After the death of Louis XIII, he relinquished his office June 23, 1643 but he was sent as plenipotentiary in the negotiations of Munster.

In October 1652, just before his death he made a large donation to Anthony Singlin, Jansen, Director of Port Royal, who is even suspected of extortion on this occasion.

His son, Armand Jean le Bouthillier de Rancé, was the founder of the Trappist order.
