Baron Carl Erik Mannerheim (1759–1837) was the son of Baron Johan Augustin Mannerheim. Born in Säter, Carl Erik was part of the Anjala League, an opposition movement during the reign of Gustav III of Sweden. However, he received an amnesty and emigrated to Finland, where he purchased Louhisaari manor in 1795. In 1805, he was elected Chairman of the Finnish Economic Society. At the beginning of Russian rule in Finland, he was chairman of the delegation accounting for matters in Finland to Tsar Alexander I. He served as Vice-President of the Senate of Finland's Economic Department (i.e., de facto head of government), and Governor of Turku and Pori provinces. He was also first Major of the Åbo province infantry regiment. He was given the hereditary title of Count (in Finnish Kreivi, in Swedish Greve) in 1824 and introduced in 1825. The title is inherited by the eldest son. The family was reintroduced in the Swedish nobility in 1947 and 1953. Members
