Between 1920 and 1922 a monument in honour of the workers who were killed in the wake of the Kapp Putsch was erected in the Weimar central cemetery. The memorial was commissioned by the Weimar Gewerkschaftskartell (Union Cartel), which conducted a competition to select a design. It was built according to plans submitted by the architectural office of Walter Gropius. Although Gropius had said that the Bauhaus should remain politically neutral, he agreed to participate in the competition of Weimar artists at the end of 1920.
