The Margraviate of Brandenburg (German: Markgrafschaft Brandenburg) was a major principality of the Holy Roman Empire from 1157 to 1806. Though initially an underdeveloped and economically modest territory, Brandenburg held electoral status within the Empire. Facing land division with Küstrin as recent as middle in the 16th century, it then quickly reunited and grew rapidly in importance after inheriting the Duchy of Prussia in 1618. Brandenburg came to play a pivotal role in both German and European history as the core of the Prussian kingdom.
Brandenburg developed out of the Northern March, founded in the territory of the Slavic Wends. It derived one of its names from this inheritance, the March of Brandenburg (Mark Brandenburg). Its ruling margraves were established as prestigious prince-electors in the Golden Bull of 1356, allowing them to vote in the election of the Holy Roman Emperor. The state thus became additionally known as Electoral Brandenburg or the Electorate of Brandenburg (Kurbrandenburg or Kurfürstentum Brandenburg).
The House of Hohenzollern came to the throne of Brandenburg in 1415. In 1417, Frederick I moved its capital from Brandenburg an der Havel to Berlin. By 1535, the electorate had an area of some 10,000 square miles (26,000 km2) and a population of 400,000. Under Hohenzollern leadership, Brandenburg grew rapidly in power during the 17th century and inherited the Duchy of Prussia. The resulting Brandenburg-Prussia was the predecessor of the Kingdom of Prussia, which became a leading German state during the 18th century. Although the electors' highest title was "King in/of Prussia", their power base remained in Brandenburg and its capital, Berlin.
The Margraviate of Brandenburg ended with the dissolution of the Holy Roman Empire in 1806. It was replaced after the Napoleonic Wars with the Prussian Province of Brandenburg in 1815. The Hohenzollern Kingdom of Prussia was the primary driving force behind the unification of Germany. The Prussian-dominated North German Confederation later transformed in 1871 into the German Empire; it was the legal predecessor of the united German Reich of 1871–1945, and as such a direct ancestor of the present-day Federal Republic of Germany,
Geography
The territory of the former margraviate, commonly known as the Mark Brandenburg, lies in present-day eastern Germany and western Poland. Geographically it encompassed the majority of the present-day German states of Brandenburg and Berlin, the Altmark (the northern third of Saxony-Anhalt), and the Neumark (now divided between Poland's Lubusz and West Pomeranian Voivodeships). Parts of the present-day federal state Brandenburg, such as Lower Lusatia and territory which had been Saxon until 1815, were not parts of the Mark. Colloquially but not accurately, the federal state Brandenburg is sometimes identified as the Mark or Mark Brandenburg.
The region was formed during the ice age, and characterized by moraines, glacial valleys, and numerous lakes. The territory is known as a Mark or march because it was a border county of the Holy Roman Empire (see also Margraviate of Meissen).
The Mark is defined by two uplands and two depressions. The depressions are taken up by rivers and chains of lakes with marsh and boggy soil along the shores; once used for peat collection, the riverbanks are now mostly drained and dry.
The Northern or Baltic Uplands of the Mecklenburg Lake Plateau have only minor extensions into Brandenburg. The approximately 230 km-long range of hills in the Mark's south begins in the Lusatian Highlands (near Żary (Sorau)) and continues past Trzebiel (Triebel) and Spremberg, then to the northwest through Calau, and ends in the bare and dry Fläming. The southern depression is generally to the north of this ridge and appears strikingly in the Spreewald (between Baruth/Mark and Plaue an der Havel). The northern depression, lying almost directly south of the Baltic uplands, is defined by the lowlands of the Noteć and Warta Rivers, the Oderbruch, the valley of the Finow, the Havelland moor, and the Oder River.
Between these two depressions is a low plateau that extends from the Poznań area westward to Brandenburg through Torzym (Sternberg), the Spree plateau, and the Mittelmark. From southeast to northwest, this plateau is intersected by the lowland of the Leniwa Obra and the Oder River below the confluence of the Lusatian Neisse, the lower Spree Valley, and the Havel Valley. Between these valleys rise a series of hills and plateaus, such as the Barnim, the Teltow, the Semmelberg near Bad Freienwalde (157 m, 515 ft), the Müggelberge in Köpenick (115 m, 377 ft), the Havelberge (97 m, 318 ft), and the Rauen Hills near Fürstenwalde (112 to 152 m, 367 to 499 ft).
The region is predominantly marked by dry, sandy soil, wide stretches of which have pine trees and erica plants, or heath. However, the soil is loamy in the uplands and plateaus and, when farmed appropriately, can be agriculturally productive.
Mark Brandenburg has a cool, continental climate, with temperatures averaging near 0 °C (32 °F) in January and February and near 18 °C (64 °F) in July and August. Precipitation averages between 500 mm and 600 mm annually, with a modest summer maximum.
History
Northern March
By the eighth century, Slavic Wends, such as the Sprewane and Hevelli (Havolane or Stodorans), started to move into the Brandenburg area. They intermarried with Saxons and Bohemians.
The Bishoprics of Brandenburg and Havelberg were established at the beginning of the tenth century (in 928 and 948, respectively). They were suffragan to the Archbishopric of Mainz; the Bishopric of Brandenburg reached to the Baltic Sea.
King Henry the Fowler started governing in the region in 928–929, allowing Emperor Otto I to establish the Northern March under Margrave Gero in 936 during the German Ostsiedlung. However, the march and the bishoprics were overthrown by a Slavic rebellion in 983; until the collapse of the Liutizian alliance in the middle of the 11th century, the Holy Roman Empire government through bishoprics and marches came nearly to a standstill for approximately 150 years, even though the bishopric was retained.
Prince Pribislav of the Hevelli came to power at the castle of Brenna (Brandenburg an der Havel) in 1127. During Pribislav's reign, in which he cultivated close connections with the German nobility, Germans succeeded in binding to the Holy Roman Empire the Havolane region from Brandenburg an der Havel to Spandau. The disputed eastern border continued between the Hevelli and the Sprewane, recognized as the Havel-Nuthe line. Prince Jaxa of Köpenick (Jaxa de Copnic) of the Sprewane lived in Köpenick east of the dividing line.
Ascanians
Early Ascanian rule
During the second phase of the German Ostsiedlung, Albert the Bear began the expansionary eastern policy of the Ascanians. From 1123 to 1125, Albert developed contacts with Pribislav, who served as the godfather for the Ascanian's first son, Otto, and gave the boy the Zauche region as a christening present in 1134. In the same year, Emperor Lothair III named Albert margrave of the Northern March and raised Pribislav to the status of king, although that was later rescinded. Also in 1134, Albert succeeded in securing for the Ascanians the inheritance of the childless Pribislav. After the latter's death in 1150, Albert received the Havolane residence of Brenna. The Ascanians also began to build the castle of Spandau.
In contrast to their leaders, who had accepted Christianity, the Havolane population still worshipped old Slavic deities and opposed Albert's assumption of power. Jaxa of Köpenick, a possible relative of Pribislav and a claim-holder to Brandenburg, controlled Brandenburg with Polish help, and ruled the land of the Stodorans. Older historical research dates this conquest to 1153, although there are no definite sources for the date. More recent researchers (such as Lutz Partenheimer) date it to spring 1157, as it is doubtful that Albert would have responded to Jaxa's actions for four years.
With bloody victories on 11 June 1157, Albert the Bear was able to reconquer Brandenburg, exile Jaxa, and found a new lordship. Because he already held the title of margrave, Albert styled himself as Margrave of Brandenburg (Adelbertus Dei gratia marchio in Brandenborch) on 3 October 1157, thereby beginning the Margraviate of Brandenburg.
Territorial expansion
The territorial limits of the original margraviate differed from the area of the current Bundesland Brandenburg, consisting merely of the Havelland and Zauche regions. In the following 150 years, the Ascanians succeeded in winning the Uckermark, Teltow, and Barnim regions east of the Havel and Nuthe, thereby extending the Mark to the Oder River. The Neumark ("New March") east of the Oder was acquired gradually through purchases, marriages, and aid to the Piast dynasty of Poland.
Settlement and administration
Because of the sandy soil prevalent in Brandenburg, the agriculturally meager principality was denigrated as "the sandbox of the Holy Roman Empire". Albert invited colonists to settle the new territory, many of whom came from the Altmark ("Old March", a later name for the original Northern March), the Harz, Flanders (hence the Fläming region), and the Rhineland. After the capture of territory along the Elbe and Havel Rivers in the 1160s, Flemish and Dutch settlers from flooded regions in Holland used their expertise to build dikes in Brandenburg. Initially, the Ascanians protected the country by settling knights in villages; castles fortified with knights were mostly located in the border region of the Neumark. After a 14th century decline in imperial power, however, knights began constructing castles throughout the principality, granting them more independence.
Decline and extinction of the dynasty
After Albert's death in 1170, his son succeeded him as Otto I, Margrave of Brandenburg. The Ascanians pursued a policy of expanding to the east and the northeast with the goal of connecting their territories through Pomerania to the Baltic Sea. This policy brought them into conflict with the Kingdom of Denmark. After the Battle of Bornhöved (1227), Margrave John I staked his claim to Pomerania, receiving it as a fief from Emperor Frederick II in 1231. The middle of the 13th century was a time of important developments for the Ascanian House, as it won Stettin (Szczecin) and the Uckermark (1250), although the former was later lost to the Duchy of Pomerania. Also around 1250 it took over Lubusz Land from then-fragmented Poland and subsequently conquered northwestern parts of the Duchy of Greater Poland in the late 13th century, moving the border east of the Oder river. Henry II, the last Ascanian margrave, died in 1320.
Succession conflict after 1319
The death of Margrave Waldemar in 1319 sparked a conflict between the neighbouring principalities of Brunswick-Lüneburg, Mecklenburg, Saxe-Wittenberg, Pomerania-Wolgast, Jawor, and Żagań, for control of different parts of the Margraviate.
The war was periodically fought between various factions due to the alliances formed, such as the Jawor-Pomeranian and Mecklenburg-Saxe-Wittenberg alliances, and the kings of Bohemia, Poland and Denmark also entered alliances with various parties.
In 1319, Wartislaw IV of Pomerania took control of the New March with Torzym Land, the Międzyrzecz castellany, annexed from Greater Poland by Brandenburg in 1297, and northern Lubusz Land, in the north-east, Henry II of Mecklenburg captured Prignitz in the north-west and Uckermark in the north, Rudolf I of Saxe-Wittenberg captured the Mittelmark, Teltow and Barnim, i.e. the central part, Otto the Mild of Brunswick-Lüneburg captured the Old March in the west.
In 1320, a large portion of the Lubusz Land passed to Duke Henry I of Jawor, who tried to reclaim it as a region lost by his grandfather Bolesław II the Horned, and afterwards its western outskirts and a portion of the Uckermark were occupied by Rudolf I of Saxe-Wittenberg. In 1320 the allied forces of Pomerania and Jawor clashed with Mecklenburg in the Uckermark, and war between Pomerania and Mecklenburg continued in 1321–1322 on the Oder River and in Mecklenburg.
By February 1322, the eastern outskirts of the Lubusz Land with Torzym and Sulęcin and the Międzyrzecz castellany were controlled by Duke Henry IV the Faithful of Żagań. After heavy fights between Pomerania and Saxe-Wittenberg around Küstrin in 1322–1323, a peace between the two parties was signed in December 1323.
Wittelsbachs
Having defeated the Habsburgs, the Wittelsbach Emperor Louis IV, an uncle of Henry II, formally granted Brandenburg to his oldest son, Louis I (the "Brandenburger") in 1323, although various portions of the margraviate were still controlled by various neighbouring principalities.
The emergence of a new, powerful rival prompted the previously warring parties to make peace with each other and cooperate. Bavarian forces soon entered the region, but in October 1323 Pope John XXII called Louis IV to annul the grant of Brandenburg to Louis V, declaring it unlawful.
As a consequence of the murder of Provost Nikolaus von Bernau in 1325, Brandenburg was punished with a papal interdict. Bavarian forces gradually seized the margraviate. King Władysław I Łokietek of Poland actively joined the ongoing war, invading Frankfurt (Oder) in 1326, and the Międzyrzecz castellany was ultimately reintegrated with Poland. From 1328 onwards, Louis was in war against Pomerania, which he claimed as a fiefdom and the conflict did not end before 1333. The rule of Margrave Louis I was rejected by the domestic nobility of Brandenburg, and, after the death of Emperor Louis IV in 1347, the margrave was confronted with the False Waldemar, an imposter of the deceased Margrave Waldemar. The pretender was recognized as Margrave of Brandenburg on 2 October 1348 by the new emperor, Charles IV of Luxembourg, but was exposed as a fraud after a peace between the Wittelsbachs and Luxembourgs at Eltville. In 1351, Louis gave the Mark to his younger half-brothers Louis II (the "Roman") and Otto V in exchange for the sole rule over Upper Bavaria.
