What helps spread nationalistic feelings throughout Europe in the early 1800s

The conquest of Napoleon Bonaparte
The social warfare programs of auto von Bismarck
The influence of the pope
The unification of the German confederation

The conquest of Napoleon Bonaparte and the unification of the German Confederation helped spread nationalistic feelings throughout Europe in the early 1800s. Napoleon's conquests and the subsequent actions taken by various European powers to resist and ultimately defeat him helped foster a sense of national identity and unity among the people of these countries. The creation of the German Confederation and eventual unification of Germany under Otto von Bismarck also played a significant role in promoting nationalist sentiments, as it brought together various German states under a single unified nation. The influence of the Pope and Bismarck's social welfare programs were not as directly related to the spread of nationalistic feelings during this time period.
