Unification of Germany

The process symbolically concluded when most of south German states joined the North German Confederation with the ceremonial proclamation of the German Empire i.e. the German Reich having 25 member states and led by the Kingdom of Prussia of Hohenzollerns on 18 January 1871; the event was later celebrated as the customary date of the German Empire's foundation, although the legally meaningful events relevant to the accomplishment of unification occurred on 1 January 1871 (accession of South German states and constitutional adoption of the name "German Empire") and 4 May 1871 (entry into force of the permanent Constitution of the German Empire).


Despite the legal, administrative, and political disruption caused by the dissolution of the Holy Roman Empire in 1806, the German-speaking people of the old Empire had a common linguistic, cultural, and legal tradition. European liberalism offered an intellectual basis for unification by challenging dynastic and absolutist models of social and political organization; its German manifestation emphasized the importance of tradition, education, and linguistic unity. Economically, the creation of the Prussian Zollverein (customs union) in 1818, and its subsequent expansion to include other states of the Austria (under Austrian Empire)-led German Confederation, reduced competition between and within states. Emerging modes of transportation facilitated business and recreational travel, leading to contact and sometimes conflict between and among German-speakers from throughout Central Europe. The model of diplomatic spheres of influence resulting from the Congress of Vienna in 1814–1815 after the Napoleonic Wars endorsed Austrian dominance in Central Europe through Habsburg leadership of the German Confederation, designed to replace the Holy Roman Empire. The negotiators at Vienna took no account of Prussia's growing strength within and declined to create a second coalition of the German states under Prussia's influence, and so failed to foresee that Prussia (Kingdom of Prussia) would rise to challenge Austria for leadership of the German peoples. This German dualism presented two solutions to the problem of unification: Kleindeutsche Lösung, the small Germany solution (Germany without Austria), or Großdeutsche Lösung, the greater Germany solution (Germany with Austria or its German-speaking part), ultimately settled in favor of the former solution in the Peace of Prague.


Historians debate whether Otto von Bismarck—Minister President of Prussia—had a master plan to expand the North German Confederation of 1866 to include the remaining independent German states into a single entity or simply to expand the power of the Kingdom of Prussia. They conclude that factors in addition to the strength of Bismarck's Realpolitik led a collection of early modern polities to reorganize their political, economic, military, and diplomatic relationships in the 19th century. Reaction to Danish and French nationalism provided for expressions of German unity. Military successes—especially those of Prussia—in three regional wars generated enthusiasm and pride that politicians could harness to promote unification. This experience echoed the memory of mutual accomplishment in the Napoleonic Wars, particularly in the War of Liberation of 1813–1814. By establishing a Germany without multi-ethnic Austria (under Austria-Hungary) or its German-speaking part, the political and administrative unification in 1871 at least temporarily solved the problem of dualism.


Despite undergoing in the later years several further changes of its name and borders, overhauls of its constitutional system, periods of limited sovereignty and interrupted unity of its territory or government, and despite dissolution of its dominant founding federated state, the polity resulting from the unification process continues its existence, surviving until today in its contemporary form known as the Federal Republic of Germany.

Dissolution of the Old Empire[edit]

Invasion of the Holy Roman Empire by the First French Empire in the War of the Second Coalition (1798–1802) resulted in crushing the Empire and allied forces by Napoleon Bonaparte. The treaties of Lunéville (1801) and the Mediatization of 1803 secularized the ecclesiastical principalities and abolished most free imperial cities and these territories along with their inhabitants were absorbed by dynastic states. This transfer particularly enhanced the territories of Württemberg and Baden. In 1806, after a successful invasion of Prussia and the defeat of Prussia at the joint battles of Jena-Auerstedt 1806 during the War of the Third Coalition, Napoleon dictated the Treaty of Pressburg which included the formal dissolution of the Holy Roman Empire and the abdication of Emperor Francis II from the nominal reign over it. Napoleon established instead a German client state of France known as the Confederation of the Rhine which, inter alia, provided for the mediatization of over a hundred petty princes and counts and the absorption of their territories, as well as those of hundreds of imperial knights, by the Confederation's member-states. Several states were promoted to kingdoms such as the Kingdom of Bavaria, the Kingdom of Saxony or the Kingdom of Hanover.^[5] Following the formal secession from the Empire of the majority of its constituent states, the Emperor dissolved the Holy Roman Empire.^[6] In his abdication, Francis released all former estates from their duties and obligations to him, and took upon himself solely the title of Emperor of Austria, which had been established since 1804.^[7]
