It is assumed that the original Westheim is a western settlement, in contrast to the eastern settlement of Ostheim. For centuries, Kornwestheim was a prosperous and wealthy farming village that benefited from the fertility of its farmland and active trade. In 1303, the counts of Asperg sold Kornwestheim to the Dukes of Württemberg. At first, it belonged to the bureau of Cannstatt and since 1719 to the bureau of Ludwigsburg out of which emerged the county in 1938 and in 1973 the larger district of Ludwigsburg.
