Jean-Baptiste du Val-de-Grâce, baron de Cloots, better known as Anacharsis Cloots, was a Prussian nobleman who was a significant figure in the French Revolution. Perhaps the first to advocate a world parliament, long before Albert Camus and Albert Einstein, he was a world federalist and an internationalist anarchist. He was nicknamed "orator of mankind", "citizen of humanity" and "a personal enemy of God".

World federalism or global federalism is a political ideology advocating a democratic, federal world government. A world federation would have authority on issues of global reach, while the members of such a federation would retain authority over local and national issues. The overall sovereignty over the world population would largely reside in the federal government.
