German nationalists, such as the Freikorps (see Marinebrigade Ehrhardt), used the old flag in protest against the Weimar Republic during the 1920s and 1930s. This included the 1920 attempt to overthrow the Weimar government, known as the Kapp Putsch. The national socialists of Adolf Hitler had a party flag based on the old colours.
