Michel Le Tellier, marquis de Barbezieux, seigneur de Chaville et de Viroflay (19 April 1603 – 30 October 1685) was a French statesman.
Le Tellier was born in Paris to a Parisian magistrate and his wife. He entered the public service and became maître des requêtes, (a higher level lawyer, or 'procureur') in 1631 for Louis XIII of France. In 1640 le Tellier was appointed Intendant of Justice for the French military stationed in Piedmont, Italy. In 1643, owing to his friendship with the head French minister Cardinal Jules Mazarin, he became Secretary of State for Military Affairs (known as 'Secretary of State for War' during that era), and was known as being an efficient administrator. He was active in the troubles associated with the aristocratic Fronde uprising, remaining loyal to Cardinal Mazarin and to the state.
In 1677 he was made Chancellor of France. One of his major contributions as chancellor included his transformation of the royal army into a considerably larger, more professional force that helped impose the absolute rule of Louis XIV, helping to ensure France's dominance of Europe. As Chancellor, he also reestablished, in April 1679, the teaching of Civil Law at the University of Paris after Pope Honorius III had prohibited it on May 11, 1219.
Le Tellier, who despised Protestantism, was one of those who influenced Louis XIV to revoke the Edict of Nantes which had previously provided religious freedoms to them. He further encouraged the persecution of the Huguenots. He died in Versailles, 15 days after the revocation had been signed by Louis XIV and himself.
