The story
On 14 May 1881, Rudolph Karstadt founded his first store Tuch-, Manufaktur- und Konfektionsgeschäft Karstadt (Karstadt fabric, factory outlet and ready-to wear store) in Wismar. In 1884, a second store was opened in Lübeck. Soon, 24 stores had been opened in all of Northern Germany. In 1920, the business was turned into a joint stock company.
