Perpetual Peace: A Philosophical Sketch by Immanuel Kant

Perpetual Peace: A Philosophical Sketch by Immanuel Kant is a political and philosophical essay about the conditions necessary for lasting peace among nations. Kant argues that peace should not be merely a temporary pause between wars, but a legal and moral order grounded in reason. He proposes principles such as republican government, respect for international law, and a federation of free states. The work also criticizes secret treaties, conquest, standing armies, and political practices that make future wars likely. Kant connects peace with human freedom, justice, and the gradual progress of moral civilization. The essay remains a foundational text in modern political philosophy and international relations.
