In the 19th century, the development of nationalism was significantly influenced by the Romantic movement, which prioritized emotions, intuition, and cultural heritage over reason and scientific understanding. Romantic artists and poets aimed to foster a collective national identity through their works. For instance, figures like Johann Gottfried Herder emphasized folklore as a means to capture the essence of a nation, advocating that true culture could be found in the everyday lives of the common people. This perspective led to the collection of folk songs, stories, and dances as vital to nation-building. In Poland, artistic expressions were crucial in maintaining national sentiments amidst foreign rule, as exemplified by Karol Kurpinski's operatic works. The section underscores how music, language, and art became tools for expressing national feelings and mobilizing popular support for independence and unity across Europe.
