The town was first mentioned in 1043 as "Scirnbeci". From 1180 on the Scharmbeck belonged to the Prince-Archbishopric of Bremen. The monastery in Osterholz was founded in 1182 and persisted until 1650, when Lower Saxony became mostly Protestant. In 1648 the Prince-Archbishopric was transformed into the Duchy of Bremen, which was first ruled in personal union by the Swedish and from 1715 on by the Hanoverian Crown. In 1823 the Duchy was abolished and its territory became part of the Stade Region in the Kingdom of Hanover.
