Polish opera may be broadly understood to include operas staged in Poland and works written for foreign stages by Polish composers, as well as opera in the Polish language.

The tradition reaches back to Italian language entertainments of the baroque. Romantic opera in Polish flourished alongside nationalism after the partition and is exemplified by the work of Stanisław Moniuszko. In the 20th century Polish opera was exported and composers such as Krzysztof Penderecki wrote operas in other languages (Ubu Rex, Die Teufel von Loudun) that were translated into Polish later.

Operas were first performed in Poland during the Baroque era in the reign of Sigismund III Vasa (1587-1632). The king himself had no interest in the arts, but his son Władysław IV (reigned 1632-1648) was an enthusiast and patron of opera while he was still a prince. In 1625 Francesca Caccini wrote an opera for Władysław when he visited Italy. This opera, La liberazione di Ruggiero dall'isola d'Alcina, was also performed in Warsaw in 1628; this is the earliest verified performance of an Italian opera outside of Italy.

Gli amori di Aci e Galatea by Santi Orlandi was also performed in 1628. When Władysław became king, he had operas staged in the hall of the royal castle and he invited Marco Scacchi's opera troupe to Poland. A dramma per musica (as serious Italian opera was known at the time) entitled Giuditta, based on the Biblical story of Judith, was performed in 1635. The composer was probably Virgilio Puccitelli. During the reign of Władysław IV a dozen or so operas were performed whose music has not survived.[1]

The next kings John II Casimir of Poland, Michał Korybut Wiśniowiecki and John III Sobieski were too busy fighting wars to show much concern for opera, although such works that did appear were highly esteemed. After the Elector of Saxony was voted King of Poland in 1697, the situation changed. The German ruler presided over a thriving operatic scene at his court in Dresden. The first public opera house in Poland was opened in 1724. The great moderniser of Polish opera was another Saxon, King August III. In 1748 he built an opera house in which works by Italian and German composers were regularly staged. A star of European opera, the composer Johann Adolf Hasse, also arrived in Poland. His work there increased opera's popularity amongst the nobility and raised the artistic standards of Polish opera to an international level. Hasse wrote the opera seria Zenobia, to a libretto by Pietro Metastasio, especially for Warsaw in 1761.

A high point of Polish opera occurred during the reign of the last king of Poland, Stanisław August Poniatowski, in spite of the political troubles that afflicted the country. During this time Poland was carved up by its neighbours, Prussia, Austria and Russia, in a series of three Partitions between 1772 and 1795, when the country disappeared off the map of Europe. Yet culture thrived, a National Theatre was opened in 1779, and it was probably during this era that the first operas in Polish were written, although not even the titles and authors of these pieces are known. In 1777 Franciszek Bohomolec wrote the text for a cantata, Nędza uszczęśliwiona (Poverty Made Happy). Wojciech Bogusławski quickly turned this into a libretto for an opera which was staged with music by Maciej Kamieński. It is the first known opera in the Polish language. The composer was a Polonised Czech; Bogusławski and Bohomolec were Polish noblemen. Bogusławski threw himself into writing drama, which later earned him the name of "the father of Polish theatre". Bogusławski wrote and staged the opera buffa Henryk IV na łowach (Henri IV Goes Hunting) with music by Jan Stefani. It was followed by Cud mniemany, czyli Krakowiacy i Górale (The Supposed Miracle, or the Krakowians and the Highlanders). The text of the latter was lost during the January Uprising of 1863 and only rediscovered in 1929 by Leon Schiller (who called it a "Polish national opera"). The premiere took place on 1 March 1794 to unprecedented applause. It occurred a few weeks before the Kościuszko Uprising against the foreign powers and the opera itself included pro-Kościuszko slogans. The authorities had the opera removed after four performances due to its unexpected popularity and anti-Partition allusions.

The fall of Poland did not stop operatic activity in the country. Wojciech Bogusławski was still at work. In the 1790s, Józef Elsner emerged in Lwów (Lviv, then Lemberg in the region conquered by Austria). Almost none of his many operas has survived, the most notable extant work being Amazonki, czyli Herminia (The Amazons, or Herminia). When Elsner took over the National Theatre in Warsaw, he began to write operas which made use of Polish folk music.

He began his work in Warsaw by composing an opera to a libretto by Bogusławski called Iskahar. However, he was doubtful of its success, since his knowledge of the Polish language was too limited for an adequate musical expression of the words. He was also concerned with the problem of the change of accents in the sung text, which could become unintelligible if they were muddled.
