The Age of Enlightenment drew European philosophers toward systematic rational inquiry, challenging inherited assumptions about knowledge, morality, and the nature of reality. Immanuel Kant, born on April 22, 1724, in Königsberg, was a German-language philosopher and a citizen of the Kingdom of Prussia who became associated with both that Enlightenment tradition and the movement known as German idealism. He was educated at the Collegium Fridericianum and subsequently at the University of Königsberg.

Kant's philosophical work took form across several substantial texts. He wrote the Critique of Pure Reason, the Groundwork of the Metaphysic of Morals, and the Critique of Practical Reason, as well as the Critique of Judgment and The Metaphysics of Morals. These works positioned him at the intersection of Enlightenment rationalism and the emerging current of German idealism, two intellectual traditions with which scholars have consistently associated his name.

Kant died on February 12, 1804, in Königsberg, the same city in which he had been born. His dual association with the Age of Enlightenment and with German idealism has been a recurring point of reference for scholars situating his philosophy within the broader intellectual life of eighteenth-century Europe.
