The Making of Nationalism in Europe

If you look at the map of mid-eighteenth-century Europe you will find that there were no 'nation-states' as we know them today.
What we know today as Germany, Italy and Switzerland were divided into kingdoms, duchies and cantons whose rulers had their autonomous territories. Eastern and Central Europe were under autocratic monarchies within the territories of which lived diverse peoples. They did not see themselves as sharing a collective identity or a common culture. Often, they even spoke different languages and belonged to different ethnic groups. The Habsburg Empire that ruled over Austria-Hungary, for example, was a patchwork of many different regions and peoples. It included the Alpine regions
–the Tyrol, Austria and the Sudetenland - as well as Bohemia, where the aristocracy was predominantly German-speaking It also included the Italian-speaking provinces of Lombardy and Venetia. In Hungary, half of the population spoke Magyar while the other half spoke a variety of dialects. In Galicia, the aristocracy spoke Polish. Besides these three dominant groups, there 1also lived within the boundaries of the empire, a mass of subject peasant peoples – Bohemians and Slovaks to the north, Slovenes in Carniola, Croats to the south, and Roumans to the east in Transylvania. Such differences did not easily promote a sense of political unity. The only tie binding these diverse groups together was a common allegiance to the emperor.

How did nationalism and the idea of the nation-state emerge?
