1724–1804 · Königsberg, Prussia (now Kaliningrad) · philosopher / professor
Immanuel Kant
Prussian philosopher whose 1795 essay 'Toward Perpetual Peace' became a founding text of liberal theories of peace through republican constitutions, law, and hospitality.
Context: Writing amid the French Revolutionary Wars, Kant addressed whether a durable peace between states was philosophically possible and under what legal conditions.
Ideas: Perpetual peace as a juridical condition, not merely an interval between wars.
Key works: Toward Perpetual Peace (1795); Critique of Pure Reason (1781); Metaphysics of Morals (1797)
Influence: Cited as an ancestor of democratic-peace theory, collective security, and cosmopolitan law. His 'preliminary articles' and 'definitive articles' are still taught in international-relations courses.
Criticism / competing readings: Historians debate whether Kant meant his federation of free states as a world government or a voluntary league; democratic-peace theorists stretch his claims further than the text warrants. His anthropology also contains views on race now widely condemned.
Documented factKant published 'Zum ewigen Frieden' in 1795 in Königsberg.
InterpretationScholars read the essay as both satire and serious constitutional proposal; the ironic inn-sign reference is widely discussed.
Competing interpretationWhether Kant endorsed eventual world republic or only a federation remains disputed among Kant scholars.

Influence: Helped turn Alfred Nobel's will toward a peace prize and modeled women's leadership in internationalism. Her correspondence with Nobel is documented by the Nobel organisation.

Documented factVon Suttner received the Nobel Peace Prize in 1905.
InterpretationHistorians credit her with influencing Nobel's thinking, while noting the exact weight of her influence is inferred from correspondence.
