The Enlightenment brought also a revival of the Polish national theater. Polish language plays were initiated at Warsaw's main theater, upon Stanisław August's efforts, from 1765 (often French plays adapted or reworked by Franciszek Bohomolec and later Franciszek Zabłocki). The first full-fledged Polish plays were the patriotic "The Return of the Deputy" by Julian Ursyn Niemcewicz (1790) and the folklore-inspired "Krakowiacy and Górale" (names of ethnographic (folk) groups of southern Lesser Poland) by the long-term theater director Wojciech Bogusławski. The latter was staged as an innovative and uplifting opera spectacle right before the outset of the Kościuszko Insurrection.
