How did Carmen become one of the world’s most popular operas after its difficult premiere?

Carmen initially faced harsh criticism and was condemned as immoral and vulgar by contemporary audiences, who were accustomed to light, moralistic works where virtue was rewarded. The opera’s focus on the lives of common folk—including Roma, smugglers, and factory workers—and its depiction of a sexually free woman who smoked and fought in public, shocked the sensibilities of the time.12

Despite this difficult premiere, Carmen became one of the world’s most popular operas due to its groundbreaking realism, which blazed a trail for the verismo school of opera. Its enduring success is driven by a combination of brilliant local color, direct emotional impact, fastidious craftsmanship, and a wealth of memorable melodies, such as the "Toreador Song" and "Habanera".123

While Georges Bizet died believing the work was a failure, his friend Ernest Guiraud was instrumental in popularizing the opera after the composer's death. The work eventually gained widespread acclaim, with figures like Pyotr Ilyich Tchaikovsky predicting its global popularity and Friedrich Nietzsche praising it as a vital "Mediterranean" antidote to the music of Richard Wagner.23
