Perpetual Peace

Immanuel Kant

Liberal internationalism

A foundational liberal text on peace, republican government, cosmopolitan right, and international order.

About the author

German philosopher (1724–1804), the central thinker of the Enlightenment. Perpetual Peace (1795) sketches the conditions for lasting peace among states: republican constitutions, a federation of free states, and a law of universal hospitality. It is the foundational text of the liberal-internationalist and cosmopolitan tradition, an enduring counterpoint to realism and the intellectual ancestor of later projects of international law and union.
