Perpetual Peace is an important essay by Immanuel Kant from 1795 which was originally published as Project for a Perpetual Peace. The original concept of perpetual peace is for peace to be a permanent fixture over a certain specific area or location. In modern times, the concept of world peace directly stems from this original idea of a perpetual peace. In this writing of Kant, he argues in favor of civil constitutions with Republican forms of government, world citizenship, free states, the abolishment of standing armies and for states not being able to use force to interfere with the constitutions or governments of another given state. This is an important work for those studying the idea of world peace and those interested in the writings of Immanuel Kant.
