Italian Renaissance theatre flourished in the 15th and 16th centuries, marking a shift from medieval religious themes to secular subjects. Influenced by classical Greek and Roman texts, it reflected humanist ideals and the rise of the merchant class. Key figures like Ariosto and Machiavelli adapted classical comedies and wrote satirical works. The period saw the development of new theatrical spaces, innovative set designs, and the emergence of commedia dell'arte, shaping the future of European drama.
