'Marine-Brigade Ehrhardt' Arm Badge (Ärmelabzeichen). The Marinebrigade Ehrhardt, also known as the Ehrhardt Brigade, was a Freikorps unit of the early Weimar Republic. It was formed on 17 February 1919 as the Second Marine Brigade from members of the former Imperial German Navy under the leadership of Hermann Ehrhardt. The brigade was used primarily in the suppression of the Bavarian Soviet Republic and the First Silesian Uprising, both in the first half of 1919. In March 1920, faced with its imminent disbanding by orders of the government in Berlin, the Marine Brigade was one of the main supporters of the Kapp Putsch that tried to overthrow the Weimar Republic. After the putsch failed and the brigade was disbanded in May, many of the former members formed the secret Organisation Consul under Ehrhardt's leadership. Before it was banned in 1922, it carried out numerous assassinations and murders in a continuation of the attempts to overthrow the Republic. This is an arm badge as worn on the left arm of the men of the Marinebrigade Ehrhardt, this is the rarely seen smaller version (Prinzengröße) and measures approximately 54 x 36 mm. The badge is complete with its original cloth backing having a piece of patriotic black-white-red ribbon in the colours of the Imperial German Flag attached. The tombak badge is showing a fair amount of its original silver finish. Rare original Feikorps arm badge in good used condition!
