The National Theatre (Teatr Narodowy) in Warsaw, Poland, was founded in 1765, during the Polish Enlightenment, by that country's monarch, Stanisław August Poniatowski.
Upon ascending the Polish throne in 1632, he built a theatre in his castle, and regular opera performances were produced there by an Italian company directed by Marco Scacchi.
From 1774 on, opera, theatre and ballet performances were held in the Radziwiłł Palace (today the official home of Poland's president).
[4] The first Polish opera was produced there on 11 July 1778, Maciej Kamieński's Poverty Made Happy, with Wojciech Bogusławski's libretto based on a comedy by Franciszek Bohomolec.
Also, at the National Theatre, from 1785 a troupe of His Majesty's Dancers (headed by ballet masters François Gabriel Le Doux of Paris and Daniel Curz of Venice) became active.
