Why did new nations arise in Europe during the mid-1800s?

National awakening also grew out of an intellectual reaction to the Enlightenment that emphasized national identity and developed a romantic view of cultural self-expression through nationhood. The key exponent of the modern idea of the nation-state was the German G. W. Friedrich Hegel. The French Revolution, although primarily a republican revolution, initiated a movement toward the modern nation-state and also played a key role in the birth of nationalism across Europe where radical intellectuals were influenced by Napoleon and the Napoleonic Code, an instrument for the political transformation of Europe. "Its twin ideological goals, nationalism and democracy, were given substance and form during the tumultuous events beginning at the end of the eighteenth century."[3] Revolutionary armies carried the slogan of "liberty, equality and brotherhood" and ideas of liberalism and national self-determinism. He argued that a sense of nationality was the cement that held modern societies together in the age when dynastic and religious allegiance was in decline. In 1815, at the end of the Napoleonic wars, the major powers of Europe met at the Congress of Vienna and tried to restore the old dynastic system as far as possible, ignoring the principle of nationality in favour of "legitimism", the assertion of traditional claims to royal authority. With most of Europe's peoples still loyal to their local province or city, nationalism was confined to small groups of intellectuals and political radicals. Furthermore, political repression, symbolized by the Carlsbad Decrees published in Austria in 1819, pushed nationalist agitation underground.
