Nationalism is a political ideology that emphasizes the interests and culture of a particular nation, often promoting national unity and identity. Romanticism, on the other hand, is an artistic and intellectual movement that emerged in the late 18th century, emphasizing emotion, individualism, and the beauty of nature. These two concepts are interconnected as Romanticism often inspired nationalist movements by celebrating the unique cultural heritage, folklore, and history of nations, fostering a sense of pride and belonging among people.
