Is The Étude Op 10 No 12 in C minor by Frédéric Chopin nicknamed Revolutionary because it started a major upheaval in Paris in 1820?

No, Chopin's Étude Op. 10, No. 12 in C minor is nicknamed the "Revolutionary Étude" due to its intense and dramatic character, not because it started a major upheaval in Paris in 1820. The piece was composed in 1831, not 1820, and its title reflects the turbulent political climate during that time in Poland, Chopin's homeland.
