Prior to the
Napoleonic Wars (1803–1815) and the end of the
Holy Roman Empire in 1806, the
Kingdom of Prussia was exclusively in the northeastern part of what would become Germany. The territories of
East Prussia,
Pomerania,
Silesia and
West Prussia all lay to the east of
Brandenburg, which was home to Prussia's capital,
Berlin. At the 1814–1815
Congress of Vienna, which redrew the map of Europe after Napoleon's defeat, Prussia was granted a significant amount of new territory, part of which brought its western border to the
Rhine. In the east, it lost some land to the
Russian Empire that it had taken during the
partitions of Poland, but it retained
Posen and gained
Swedish Pomerania and roughly half of
Saxony. Its additions in the west, which were geographically separate from the rest of the Kingdom, included parts of the
Duchy of Westphalia and the regions that became the
Grand Duchy of the Lower Rhine and the
Province of Jülich-Cleves-Berg. The Congress of Vienna also established the
German Confederation. The loose federal association initially comprised 39 states, of which the
Austrian Empire and the Kingdom of Prussia were the largest. The Prussian territories that had not been in the Holy Roman Empire – East and West Prussia and Posen – were not part of the Confederation. Prussia's province system was introduced during the
Stein-Hardenberg Reforms in 1815. The original ten provinces were Brandenburg, East Prussia, West Prussia, Posen, Pomerania, Silesia, Saxony, Westphalia, Lower Rhine and Jülich-Cleves-Berg. The Prussian government appointed the heads of each province, who were known as
Oberpräsidenten (governors). The governor represented the Prussian state in the province and was responsible for implementing and supervising the central prerogatives of the Prussian government. The provinces of Prussia were further subdivided into
governmental districts (
Regierungsbezirke) that were subject to the governor. The governmental districts were further divided into
Kreise and then into townships (
Gemeinden). Each province had a provincial parliament. Initially called "Provincial Estates" (), they were established in 1823 as representative bodies based on the
Prussian estates, such as nobility, high clergy and
burghers. Initially there was no Prussia-wide representation of the estates or the people of Prussia, which left the provincial assemblies as the highest-level parliamentary institutions. They had a largely advisory function, and where they were authorised to decide on provincial matters, they were subject to royal supervision. They did not have the right to legislate or authorise taxes. The provincial estates were summoned once in three years. Their meetings were not open to the public and their proceedings could not be published. Only landowners were eligible to be elected, and quotas by estate ensured that the nobility dominated. Representatives of the third and fourth estates elected representatives indirectly through electors. The system led to marked imbalances in representation. In the Rhineland, for example, where the nobility owned only four percent of the land, they were allotted one-third of the seats. Representatives from large industrial and commercial centers had up to 120 times more constituents than their counterparts from the nobility. The southwestern German
Province of Hohenzollern, created in 1850, was an exception to Prussia's provincial structure. It was subordinate overall to ministries in Berlin, although its district president was equal to the governors of the other Prussian provinces. Many of its administrative functions came under the responsibility of the nearby Rhine Province. In response to the
German revolutions of 1848–1849, King
Frederick William IV granted the Kingdom of Prussia a
constitution in 1848, which was
amended in 1850. It created a two-chamber Prussian parliament consisting of a non-elected
House of Lords and a
House of Representatives that gave the vote to adult Prussian men under a
three-class franchise. There was no specific reference to the provinces in the two constitutions, but with the introduction of the Prussian House of Representatives, the Provincial Estates were no longer the highest-level parliamentary institutions in the Kingdom. == North German Confederation (1866–1871) and German Empire (1871–1918) ==
