In 1872, European Americans founded a modest settlement at what was called Missouri Crossing. It got its name because the Lewis and Clark Expedition crossed the river there on their journey to explore the Louisiana Purchase. The settlers named their new community Edwinton, after Edwin Ferry Johnson, an engineer with the Northern Pacific Railroad. Less than a year later, the name was changed to Bismarck, in honor of German Chancellor Otto von Bismarck, aiming to attract German immigrants.
