Representatives of the former included Jean-Jacques Rousseau, in Extrait du Projet de Paix Perpetuelle de Monsieur l'Abbe Saint-Pierre (1756), Immanuel Kant, in his Thoughts on Perpetual Peace, and Jeremy Bentham who proposed the formation of a peace association in 1789.

Sixteen peace petitions to Parliament were signed by members of the public, anti-war and anti-Pitt demonstrations convened and peace literature was widely published and disseminated. The first peace movements appeared in 1815–16. In the United States the first such movement was the New York Peace Society, founded in 1815 by the theologian David Low Dodge, and the Massachusetts Peace Society. It became an active organization, holding regular weekly meetings, and producing literature which was spread as far as Gibraltar and Malta, describing the horrors of war and advocating pacificism on Christian grounds.
