Giuseppe Mazzini and the founding of Young Europe in Berne, 1833.
Germany, Italy, and Switzerland were divided into empires, duchies, and cantons whose rulers had their territories.
Aristocracy was the predominant segment of the continent politically and socially. Most people are made up of the peasantry. Industrialization began in England in the second half of the eighteenth century. New social groups have emerged: the population of the working class and the middle classes made up of industrialists, entrepreneurs, and professionals.
As conservative regimes tried to consolidate their power, liberalism and nationalism came to be increasingly associated with revolution in many regions of Europe such as the Italian and German states, the provinces of the Ottoman Empire, Ireland and Poland. These revolutions were led by the liberal-nationalists belonging to the educated middle-class elite, among whom were professors, schoolteachers, clerks and members of the commercial middle classes.
The first upheaval took place in France in July 1830. The Bourbon kings who had been restored to power during the conservative reaction after 1815, were now overthrown by liberal revolutionaries who installed a constitutional monarchy with Louis Philippe at its head.
