Jobst paid very little attention to Brandenburg, and the period was used by many of the noble families to enrich themselves at the expense of the poorer and weaker towns, to plunder traders, and to carry on feuds with neighbouring princes.
Brandenburg was ravaged impartially by both parties, and in 1627 George William attacked his brother-in-law, Gustavus Adolphus of Sweden, who was using Prussia as a base of operations for his war against Poland.
The Brandenburg troops then assisted the Swedes until after the death of Gustavus in 16 3 2, and the Swedish defeat at NOrdlingen in 1634, when the elector assented to the treaty of Prague, which was made in May 1635 between the emperor Ferdinand II.
Bishopric of Brandenburg was a diocese established by Otto the Great in 948, including the territory between the Elbe on the west, the Oder on the east, and the Black Elster on the south, and taking in the Uckermark to the north.
The disturbances of 983 practically annihilated it; bishops continued to be named, but they were merely titular, until the downfall of the Wends in the twelfth century and the German settlement of that region revived the bishopric.
Bishop Wigers (1138–60) was the first of a series of bishops of the Premonstratensian order; which chose the occupants of the see until 1447; in that year a bull of Nicholas V gave the right of nomination to the elector of Brandenburg, with whom the bishops stood in a close feudal relation.
