The Provinces of Prussia () were the main administrative divisions of the Kingdom of Prussia from 1815 to 1947. Provinces constituted the highest level of administration in the Kingdom and its successor, the Free State of Prussia, until Nazi Germany established de facto direct rule over provincial politics in 1933. The provinces were abolished along with Prussia itself in 1947 following World War II.
The provinces were established after the Congress of Vienna granted Prussia significant new territories in 1815. Initially they were ruled by an appointed governor and an estates-based parliament, but beginning in 1876, self-administration and democratic participation were broadened. During the Weimar Republic, the provincial parliaments were further democratized, and the provinces gained a voice in the Prussian parliament through the introduction of the Prussian State Council. All traces of democracy were lost under Nazi rule.

German Confederation (1815–1866)
thumb|381x381px|Map showing Prussia's expansion from 1807 to 1871
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)
In the 1866 Austro-Prussian War, Prussia defeated Austria to become the predominant state in German-speaking Europe. The German Confederation collapsed with Austria's defeat and was replaced by the Prussia-dominated North German Confederation, which had a total of 22 states. Prussia annexed three of the north German states that had supported Austria in the war – the Kingdom of Hanover, the Electorate of Hesse and the Duchy of Nassau – along with the Duchies of Schleswig and Holstein; they became the Prussian provinces of Hanover (1868), Hesse-Nassau (1868) and Schleswig-Holstein (1867). The state of Prussia required them to establish provincial representative bodies (Provincial Estates) on the same estates-based lines as the existing provinces.thumb|right|300px|Prussia with the outlines of its provinces in the [[German Empire, 1914]]
Prussia's victory in the Franco-Prussian War led to the foundation of the German Empire in 1871. It comprised what had been the North German Confederation, three new states in southern Germany plus the imperial territory of Alsace–Lorraine; Prussia's boundaries did not change. With two-thirds of the Empire's territory and three-fifths of its population, Prussia dominated the new state.
A major change to the administrative structure of Prussia's provinces took place beginning in 1876. The Provincial Ordinance of 29 June 1875 divided the provinces into a state (Prussian) administrative district – the province itself – and a coterminous local self-governing body called the Provincial Association (). It strengthened self-administration in the provinces by putting specific areas such as road building and social welfare under the responsibility of the provincial associations. The ordinance became effective on 1 January 1876 in Brandenburg (except for Berlin), Pomerania, Silesia and Saxony. Similar ordinances specific to single provinces followed in Hanover (1884), Hesse-Nassau (1885), Westphalia (1886), the Rhine Province (1887) and Schleswig-Holstein (1888). Posen was the only province in which the structural change was not enacted. In an unrelated development, Berlin withdrew from Brandenburg and became an independent city in 1881.
Some territorial changes were decided by plebiscites. Northern Schleswig voted on 10 February 1920 in favor of annexation to Denmark, and eastern Upper Silesia went to Poland even though 60% of voters in the 1921 Upper Silesia plebiscite chose to remain part of Germany.
In 1920 Berlin, an independent city not part of any province, was extended considerably at the expense of Brandenburg through the Greater Berlin Act.
The Free State of Waldeck-Pyrmont was the only territory Prussia gained during the Weimar Republic. The Pyrmont district voted to join Prussia (the Province of Hanover) in a 1921 plebiscite. Waldeck followed with its own plebiscite in 1929 and became part of the Prussian Province of Hesse-Nassau.

The Free State promoted the democratisation of the provinces, resulting in the provincial Landtags being elected directly by the voters. The 1920 Prussian Constitution provided for a State Council similar to the national Reichsrat to represent the interests of the provinces at the state level. Its members were elected by the provincial Landtags, with the number of members from each province proportional to its population. The provinces were also represented in the national Reichsrat. Unlike in all other states of the Weimar Republic, whose Reichsrat representatives had to be members of the state's ministry, half of Prussia's representatives were appointed from among provincial administrative authorities.
Nazi Germany (1933–1945)
Following the Nazi seizure of power in 1933, the Law on the Reconstruction of the Reich was enacted on 30 January 1934. It de-federalized the German Reich and created a centralized state. Prussia and its provinces formally continued to exist, but the state Landtag and provincial parliaments were abolished and governance was placed under the direct control of a Reichsstatthalter (Reich governor). In addition, the Law on the Abolition of the Reichsrat of 14 February 1934 ended the participation of the state and its provinces in the Reich legislative process. The Prussian State Council, however, continued to exist until 1945 in a much altered form.
Beginning in 1934, Posen-West Prussia came under the de facto administration of Brandenburg, and on 1 October 1938, it was officially dissolved. Its lands were subsequently incorporated into the neighbouring provinces of Pomerania, Brandenburg and Silesia.
Two provinces, Saxony and Hesse-Nassau, underwent significant changes in July 1944. The Erfurt region of Saxony was ceded to Thuringia, while the remainder of the province was divided into the Province of Magdeburg and the Province of Halle-Merseburg. At the same time, Hesse-Nassau was partitioned into the Province of Kurhessen with its capital at Kassel and the Province of Nassau with its capital at Wiesbaden.
Abolition
Following World War II, Prussia fell into all four of the Allied occupation zones, with the eastern portions in the Soviet zone and the largest share of the western part in the British zone. The provinces were abolished at different times depending on which zone, or zones, they were in. Brandenburg, which was dissolved on 6 February 1947, was the last to go. Prussia itself was formally abolished on 25 February 1947 by order of the Allied Control Council, the governing authority of occupied Germany.
