Early history King
Henry the Fowler in 929 marched against the
Polabian Slavs settling east of the
Elbe River and defeated them in a battle near
Lenzen. Occupying the eastern riverbank, Henry had a fortification built on a hill above the
Havel tributary, near its mouth into the Elbe. His son Otto I continued the expeditions and in 936/37 established the
Saxon Eastern March (
Marca Geronis) on the conquered territories. In 948 he founded the dioceses of Havelberg and
Brandenburg, initially suffragans to the
Archbishops of Mainz, from 968 to the newly established Archdiocese of Magdeburg. Part of the
Northern March from 968, Havelberg diocese was occupied by revolting
Lutici tribes in the
Great Slav Rising of 983 and the bishops remained far from their see. Not until 150 years later, King
Lothair III of Germany re-occupied Havelberg in 1130; the eastern Elbe bank was finally reconquered by the
Ascanian margrave
Albert the Bear in 1136/37. In 1140 the northern part of the see was annexed to the newly formed
Bishopric of Cammin. Originally built as a Romanesque basilica, the Cathedral was severely damaged by fire in 1279 and then converted to the Gothic style. The complex eventually grew to include a priory, deanery, brewery, oast house, hospital, school, and residences for the canons. The diocesan and secular territory were already separated in 1151. However, the bishops held no secular rights in the town of Havelberg itself, which was enfeoffed to the Brandenburg margraves. A charter issued by Emperor
Frederick Barbarossa to declare the residence an episcopal city was never carried out, and in the following centuries, the Havelberg bishops gradually moved their residence to their
Amt Wittstock about to the northeast. In 1383 the
Holy Blood of Wilsnack became a famous pilgrimage site, while
Dietrich Man was bishop. In 1395, Bishop Johann III Wöplitz incorporated St. Nicholas' Church at Wilsnack into his episcopal household so that two-thirds of the income flowed directly to the bishopric.
Luther and others criticized it as providing an incentive for church officials to encourage dubious shrines. From the 14th century onwards, the Havelberg bishops also used
Plattenburg Castle as a summer residence. After long-lasting quarrels with the mighty Brandenburg
prince-electors, the Premonstratensian chapter finally gave in to transform Havelberg into a
collegiate church (
Stift). From 1514 onwards the
deans of the cathedral were appointed by the Margraves of Brandenburg. In the course of the Protestant Reformation, the Bishopric of Havelberg turned
Lutheran and from 1554 was administrated by
Joachim Frederick of Hohenzollern, son of Elector
John George of Brandenburg. The Bishopric was finally secularised and incorporated into Brandenburg in 1571. Its annexation was complete, when Joachim Frederick succeeded his father as Brandenburg elector in 1598. ==Bishops==
