Anacharsis Cloots

Jean-Baptiste du Val-de-Grâce, baron de Cloots (24 June 1755 – 24 March 1794), better known as Anacharsis Cloots (also spelled Clootz), was a Prussian nobleman who was a significant figure in the French Revolution. He was nicknamed "orator of mankind", "citoyen de l’humanité" and "a personal enemy of God".

Born near Kleve, at the castle of Gnadenthal, he belonged to a noble Prussian family of Dutch origin. The young Cloots, heir to a great fortune, was sent to Paris at age eleven to complete his education, and became attracted to the theories of his uncle the abbé Cornelius de Pauw (1739–1799), philosophe, geographer and diplomat at the court of Frederick II of Prussia. His father placed him in the military academy of Berlin, but he withdrew at the age of twenty and travelled through Europe, preaching his revolutionary philosophy and spending his money as a man of pleasure.

On the breaking out of the Revolution, Cloots returned in 1789 to Paris, thinking the opportunity favorable for establishing his dream of a universal family of nations. On June 19, 1790 he appeared at the bar of the National Constituent Assembly at the head of thirty-six foreigners, and, in the name of this embassy of the human race, declared that the world adhered to the Declaration of the Rights of Man and of the Citizen. After this, he was known as the orator of the human race, by which title he called himself, dropping that of baron, and substituting for his baptismal names the pseudonym of Anacharsis, from the famous philosophical romance of the abbé Jean-Jacques Barthélemy.
