Because of its location at the confluence of three rivers and near the geographic center of the United States, Fort Wayne has from its earliest days been an important marketplace—first as a fur-trading post and now as the headquarters of major corporations. The outpost for "Mad" Anthony Wayne during the Indian struggles after the Revolutionary War and later the resting place of John Chapman, known also as Johnny Appleseed, the city figures prominently in the history of the settling of the western frontier. Fort Wayne, three times honored as an All-American City, is Indiana's second-largest city and the seat of Allen County.
