Earliest references to the family include a document from 1254 in which
Bernhardus de Bassewicze is mentioned. It is unknown whether the family was among the German families immigrating the Mecklenburg region since the 12th century in the course of the
German eastward expansion or whether the Bassewitz family was of Slavic origin. Slavic tribes (the
Wends) settled in the area since the 7th century. At the time of colonization, German families took the name of the place where they settled as their surname, while at the same time, Wendish families began to adopt German names. In the early 14th century, the Bassewitz family was already documented as being in possession of several estates in Mecklenburg. It therefore seems more likely that the family is of Wendish origin. Among the first estates owned by the family since the late Middle Ages and considered by it to be ancestral houses (Stammhaus) are Basse, Dalwitz, Hohen Luckow,
Prebberede, Levetzow and
Lühburg. The family is split into two branches – the
Mecklenburgian branch and the
Wendish branch. All legitimate male-line descendants of Count Henning Friedrich bear the name
Graf von Bassewitz (
Count von Bassewitz). Four descendants of Count Henning Friedrich von Bassewitz held the highest office (prime minister) in
Mecklenburg:
Count Carl Friedrich (1720
–1783)
— President of the Privy Council
Count Bernhard-Friedrich (1756
–1816)
– President of the Privy Council
Count Henning Karl Friedrich (1814
–1885)
– President of the Privy Council
Count Karl (1855
–1921)
– President of the State Ministry of Mecklenburg-Schwerin from 1901 through 1914. == Elevations and Additions to the Coat of Arms ==
