As European nations struggled for independence and identity through the 19th century, composers turned to folk music, national legends, and local landscapes for inspiration. Music became a political act — a way of asserting cultural identity against imperial powers.
The Czech Smetana wrote Má vlast (My Homeland) while his country was under Austrian rule. The Norwegian Grieg drew on folk melodies. The Russian "Mighty Five" (including Mussorgsky) rejected German musical dominance and built a distinctly Russian sound. Sibelius became a symbol of Finnish independence.
This era also produced some of the most immediately accessible music in the repertoire — Dvořák's New World Symphony, Grieg's Peer Gynt, Tchaikovsky's ballets — music that wears its heart on its sleeve.
