Marne was originally called Berlin due to the many German settlers in the area. It received a post office in 1852 and was platted in 1857. Due to anti-German sentiments during World War I, the name was changed in 1919 to Marne, to honor those soldiers who fought in the Second Battle of the Marne.[4] However, the name Berlin continues to manifest in many ways, including Berlin Baptist Church, the Berlin Fairgrounds, Berlin Fair Drive and the Berlin Raceway, where Johnny Benson Jr. raced.
