Bismark is a town in the Stendal district, in the historic Altmark region, which is located in the northern part of the state of Saxony-Anhalt, Germany. It is situated approximately 22 km (14 mi) west of Stendal in north-eastern Germany.
In the early 12th century, the area then under the rule of Albert the Bear was settled with peasants migrating from the Low Countries. The town's name is derived from the nearby river Biese (after Dutch: bies meaning rush plants); though it may also refer to the bishop's march, a possession of the Havelberg bishops mentioned in a 1209 deed issued by the Ascanian margrave Albert II. With the Altmark, Bismark was part of the Margraviate of Brandenburg until it was adjudicated to the Prussian Province of Saxony after the 1815 Congress of Vienna.
One Herbordus of Bismarck was mentioned holding the office of a Schultheiß in Stendal about 1270. His descendant Otto von Bismarck received the honorary citizenship of Bismark in 1895.
