The spread of nationalistic feelings in Europe in the early 1800s was facilitated by various factors such as the defeat of Napoleon and the subsequent Congress of Vienna, which led to changes in borders and the creation of new nation-states. Additionally, the rise of romanticism and the emphasis on cultural and linguistic identity contributed to the growth of nationalistic sentiments. Other factors that helped spread nationalistic feelings included the development of mass media, the growth of industrialization and urbanization, and the emergence of nationalist leaders and movements.
