Hohenschönhausen was affected by the Seven Years' War, and was plundered by Austrian and Russian troops after Frederick the Great's defeat at the Battle of Kunersdorf. From 1817 the village and the surrounding estates were under the control of the local state councillor, Christian Friedrich Scharnweber. Under his tenure and those of his successors, Hohenschönhausen began expanding along the road to Berlin. Apart from the settlements, at this point cereals were also widely grown and, after the easing of restrictions in 1810, milled on-site. As the 19th century progressed and Germany began to industrialise, Hohenschönhausen benefitted from investment in infrastructure, such as the opening of an electric tram line in 1899, and a brewery which opened in the early 1890s.
