, ancestral seat of the House of Schaumburg, circa 1800. The Schaumburgs were named after
Schauenburg Castle, near
Rinteln on the
Weser, where the owners started calling themselves
Lords (from 1295
Counts) of Schauenburg.
Adolf I probably became the first
Lord of
Schauenburg in 1106. In 1110,
Adolf I, Lord of Schauenburg was appointed by
Lothair, Duke of Saxony to hold
Holstein and
Stormarn, including
Hamburg, as
fiefs. Holstein was occupied by
Denmark after the
Battle of Stellau (1201), but was reconquered by the Count of Schauenburg and his allies in the
Battle of Bornhöved (1227). After the death in 1640 of
Count Otto V without children, the House of Schaumburg became extinct. The County of Holstein-Pinneberg was merged with the
Duchy of Holstein. The County of Schaumburg proper was partitioned among the Schaumburg heirs into three parts, one incorporated into the ducal
Brunswick and Lunenburgian Principality of Lüneburg, the second becoming the County of
Schaumburg-Lippe and the third continuing the name
County of Schaumburg, ruled in
personal union by
Hesse-Cassel. ==List of states ruled by the House of Schaumburg==
