What is the historical context of Spanish comic operetta?

Spanish comic operetta, known as 'opereta' in Spanish, flourished primarily during the late 19th and early 20th centuries (roughly 1880s-1930s). It emerged as a reaction against the more serious opera forms, seeking lighter entertainment. It coincided with a period of social and political change in Spain, often incorporating satirical elements to comment on contemporary events and societal norms. The rise of the middle class provided a larger audience for this form of entertainment, which was both accessible and engaging.
