Rheinmetall is a “champion partner” of Dortmund, and the company’s banners are displayed on advertising boards during matches. The agreement has caused friction among supporters of different stripes, with some Dortmund fans going so far as to withdraw their support for the club.
Founded in 1889 as “Rheinische Metallwaaren- und Maschinenfabrik Actiengesellschaft,” Rheinmetall was one of the largest arms manufacturers in Germany during both World Wars. It used forced labor during the Second World War.
