According to the historian Wolfram Siemann, there are several common features that were decisive, in varying degrees, for the European countries and regions. First, the uprisings of the "grassroots revolution" were mostly carried by those strata that were most affected by hunger, unemployment and lack of social prospects in the countryside and in the cities. Then, in the constitutional bodies newly created by the uprisings, the liberals' struggle to enshrine civil rights in state constitutions began.
The socio-economic crisis
The socio-economic crisis of pre-industrial, artisanal professions, based on the pre-March overpopulation of entire regions, favoured the incipient proletarianisation of the large cities as well as large parts of the rural areas. The old class order finally collapsed. Pauperism, the onset of industrialization, the market orientation of professions and classes, and the prolonged crisis of the crafts are terms that characterize the profound changes of the two pre-revolutionary decades. This crisis manifested itself in Luddism, persecutions of Jews, or demands for guild protection of the crafts from the competition of capital. The movement of 1848 - together with the peasant revolt often referred to as the basic revolution - was ambivalent in nature: it expressed itself both as a defensive crisis against the direct manifestations of early industrialization and as a struggle for emancipation of the politically uninfluential strata of the population.
Hunger crises
A second common feature is the crop failures and subsequent famine and dearth crises of 1845 and 1846, culminating in 1847. This was the last great famine in the industrialized countries of Europe, with tumults and a hugely increased wave of emigration in the second half of the 1840s. The worst pre-revolutionary hardship was in Ireland, but famines in German regions - not least Silesia - also had a great public resonance.
International economic crisis
An international economic crisis overlaid the preceding hunger crisis and led to a wave of strikes in German cities in April 1848. Many data confirm a profound process that already led Friedrich Engels in retrospect to the judgement that the world trade crisis of 1847 had been the real mother of the February and March revolutions (→ British railway crisis).
Struggle for law and constitution
A fourth European dimension lies in the systemic affinity of constitutional demands. Everywhere, internal political struggles developed into disputes over a new order based on a written constitutional document. It was about law and constitution - about civil rights and constitution. This was already the case in the July Revolution of 1830, but it happened even more strongly in the run-up to the Revolution of 1848, which received its initial impulse not from France but from Switzerland and Italy. The issue was always the revision or enactment of a constitution: example: At the center of the so-called "March Demands" circulating in Germany were constitutional demands: Fundamental rights, especially freedom of the press and assembly, jury courts, people's armament - in very different senses - and elections to a national parliament.
The crisis of the international system of 1815
Another European dimension lies in the character of traditional international politics, based on international treaties and relations. It was immediately clear to contemporary politicians, above all Metternich, who was still serving as foreign minister and state chancellor, that in the spring of 1848 the international system founded at the Congress of Vienna in 1815 was at stake. This was a matter of politics between European states, and the German Confederation, which had been created in 1815 as a subject of international law, counted as one of them. In 1848 it was called into question; finally it transferred all powers to the revolutionary Provisional Central Authority in Frankfurt. The initiative for this had come from the Frankfurt National Assembly. Its real purpose was to draft an imperial constitution for the whole of Germany. With its first great act the National Assembly reached far beyond this by establishing a national government. This was a revolutionary act. On June 28, 1848, the National Assembly established an imperial government consisting of an imperial administrator, a prime minister, and imperial ministers of foreign affairs, domestic affairs, finance, justice, commerce, and war. In the overall assessment, researchers today agree that the revolution and also the work of unification did not fail because of a fundamental resistance of the European powers to German unity. The revolution of 1848/49 came up against the edge of a possible great European war, which could have unleashed the breakthrough of the principle of nationality and anticipated a later development in the 19th century. The European powers, led by England and Russia, worked against this.
The politics of European persecution and exile
A repressive variant of this international policy was the concerted action of the counter-revolution. Here Austria, Russia, and from 1850 onwards France and Belgium also participated in police cooperation. This policy of European persecution - and the suppression of the European revolution - created a sixth dimension that corresponded to its European character: European exile. Switzerland and Alsace served as temporary protection, London developed into the central transit point, and the United States of America was the actual place of escape.
The European character of nationalism
A seventh dimension is related to the European character of nationalism. For many nationalities, the myth of the "unredeemed" nation was formed in the first half of the nineteenth century; this included first and foremost the Greeks, Italians, Hungarians, Poles, but also the Czechs and, according to the wording of some oppositional propaganda, the Germans. The roots of this nationalism lay in the French Revolution of 1789, which was the model for national symbols, colours and flags. In the Vormärz, under the system of the Restoration, the further myth of the "springtime of peoples" developed. In the 1820s it expressed itself throughout Europe in the movement of philhellenism, the enthusiasm for the Greek struggle for freedom, and in the 1830s, after the failed Warsaw Uprising of November 1830, in the common European wave of Polish friendship. This pre-March utopia collapsed in the face of the possibility, now suddenly visible in 1848, of transforming nationality into the state-nation. Hans Rothfels once aptly described the nationalities of the 19th century as "a kind of nation aspirants": as ethnic minorities striving for more independence and still seeking their political unity. "From the unity of the nation to the discord of nationalities" - this is the formula one could use to describe the dilemma that developed.
The Frankfurt National Assembly succeeded in finding an answer to the nationality question at home. The nationalism of 1848/49, based on the constitutional state, offered the protection of national minorities by respecting their native languages and religiosity. The Imperial Constitution of 1849 had assured this as a fundamental right in its Clause 188. A similar balance was achieved in the draft submitted by the Constitutional Committee of the Vienna Imperial Diet for the multi-ethnic state of the Habsburg Monarchy. Neither of these constitutions came into being in this form, but they did point the way to peaceful coexistence of different nationalities in a united state.
The pacifist internationalism
A last - eighth - European dimension has only recently been properly perceived. It is the "pacifist internationalism" (Dieter Langewiesche). In September 1848 a first international peace congress took place in Brussels, in August 1849 they met in Paris and a year later in the Paulskirche. The congresses called on the states to disarm, to abolish standing armies, to renounce interventions and not to finance wars of third powers.
