Following the dissolution of the Holy Roman Empire in 1806 and the Congress of Vienna in 1815, the various German states gained nominal sovereignty. However, the reunification process that culminated in the creation of the German Empire in 1871, produced a country that was constituted of several principalities and dominated by one of them, the Kingdom of Prussia after it had ultimately defeated its Austrian rival. Its territory covered some 60 percent of the territory that was to become the German Reich.
The German Confederation was established at the Congress of Vienna in 1815 and the Kingdom of Prussia was a member until the dissolution in 1866 following the Austro-Prussian War. The Prussian state was initially subdivided into ten provinces. The Prussian government appointed the heads of each province known as Oberpräsident. The Oberpräsident represented the Prussian government in the province, and was busy with implementing and supervising central prerogatives of the Prussian government. The provinces of Prussia were further subdivided into government districts, subject to the High Commissioner. As to self-rule each province also had a provincial diet, the members of which were elected in indirect election by county councillors and city councillors of the constituent rural counties and independent cities. Western Provinces:
In 1829 the Province of Prussia was created by the merger of East Prussia and West Prussia, lasting until 1878 when they were again separated. Congruent with the Kingdom of Prussia proper, its territory, like the province of Posen, was not part of the German Confederation.
Province of Prussia ; regions: Danzig, Gumbinnen, Königsberg and Marienwerder
In 1866, following the Austro-Prussian War, Prussia annexed several German States that had been allied with Austria and, together with previously occupied Danish territory, organized them into three new provinces:
Schleswig-Holstein ; regions: Holstein and Schleswig; in 1876 Saxe-Lauenburg, a separate German state, was merged in.
German Empire
The outcome of the Austro-Prussian War put an end to the aspirations of a grand unified state consisting of all German-speaking states. Instead the North German Confederation was created under Prussian leadership. Following the Franco-Prussian War and the incorporation of the southern states of Bavaria, Baden and Württemberg into the confederation, the German Empire was proclaimed in 1871. From 1875 the provinces were bodies combining regional home rule through representatives delegated from each rural and urban district, forming the provincial diet with a 6-year term, which elected from its midst a head of this self-administration, the Landesdirektor, and a provincial government as well as part of the superordinated overall Prussian royal administration, supervising - on a provincial range - the self-governing municipalities and counties as well as each governorate. For this purpose the respective Prussian minister of interior affairs appointed a High Commissioner to each province, who fulfilled his task with the help of a Prussian government-appointed provincial council. In 1881 the final province of the Kingdom of Prussia was established when Berlin was separated from Brandenburg.
Berlin carried out the duties of a Landesdirektor in the other provinces, while the city council doubled as the provincial committee. The Prussian government-appointed chief of police

Weimar Republic
After the fall of the German Empire the Kingdom of Prussia was reconstituted with a republican government as the Free State of Prussia. The Free State promoted the democratisation of the provinces, the provincial parliaments were elected in direct elections by the voters, unlike before when elected county councillors chose from their midst members for the provincial parliaments. Prussia had to cede virtually all territory belonging to the provinces of Posen and West Prussia to the newly created state of Poland and the League of Nations mandate of the Free City of Danzig. Smaller areas had been ceded to Belgium, Czechoslovakia, Denmark, the League of Nations mandate of the Memel Territory, Poland, and the Mandatory Saar . Prussia and its provinces formally continued to exist even though political control was eventually taken over by the National Socialist German Workers Party following their rise to power in 1933. The following is a summary of the changes in the Prussian provinces between 1919 and 1945:
Berlin
Brandenburg ; regions: Frankfurt and
East Prussia ; regions: Allenstein, Gumbinnen, Königsberg and West Prussia
Hanover ; regions:, Hanover,, Lüneburg, and Stade
Hesse-Nassau ; regions: Kassel and Wiesbaden. In July 1944, the province was partitioned into two new provinces along the lines of its regions: the Province of Kurhessen ; region: Kassel; and the Province of Nassau ; region: Wiesbaden.
Rhineland ; regions:, Cologne, Düsseldorf, Koblenz and Trier
Saxony ; regions:, Magdeburg and. In July 1944, the province was partitioned along the lines of its regions. Erfurt was ceded to Thuringia, while the bulk of the province was divided into the Province of Magdeburg and the Province of Halle-Merseburg
Westphalia ; regions: Arnsberg, Minden and Münster
Prussia did not survive the defeat and the division of Germany following the end of World War II in 1945 and was formally abolished in February 1947. Several of its provinces attained statehood or became a part of other post-war states in East Germany and West Germany.
