Perpetual Peace: A Philosophical Sketch (German: Zum ewigen Frieden. Ein philosophischer Entwurf) is a 1795 book authored by German philosopher Immanuel Kant. In the book, Kant advances ideas that have subsequently been associated with democratic peace, commercial peace, and institutional peace.
Immanuel Kant (April 1724 – 12 February 1804) was a German philosopher and one of the central Enlightenment thinkers.[25][26] Born in Königsberg, Kant's comprehensive and systematic works in epistemology, metaphysics, ethics, and aesthetics have made him an influential figure in modern Western philosophy.
