[1] The family has its roots in the Altmark region, descending from Herebord von Bismarck (d. 1280), the first verifiable holder of the name, mentioned about 1270 as an official (Schultheiß) at the city of Stendal in the Margraviate of Brandenburg.
Herebord's great-grandson, Nicolaus (Klaus) von Bismarck, mentioned in 1328 and 1377, was a councillor and a loyal supporter of the Wittelsbach margrave Louis I, over which he fell out with the revolting Stendal citizens and was compensated with the manor and estate of Burgstall in 1345.
The estate of Krevese was sold in 1819, and the estate of Schönhausen II in 1830. Notable members of the Crevese-Briest branch of the family were Levin Friedrich von Bismarck (1703–1774) and his son August Wilhelm von Bismarck (1750–1783), both Prussian ministers (of Justice and Finances) under Frederick the Great.
In 1815, the Prussian Junker family's most notable member, Otto von Bismarck, was born in the manor of Schönhausen I.
As Prime Minister of Prussia since 1862, he gained the comital title (Graf) of Bismarck-Schönhausen in 1865 and the hereditary princely status of a Fürst von Bismarck after the Franco-Prussian War in 1871, followed by the Proclamation of the German Empire on 18 January 1871.
Two ships of the German Imperial Navy (Kaiserliche Marine), as well as a battleship from the World War II era, were named after Otto von Bismarck.
