Before he participated in the Stuttgart 21 protests, Wagner had had no political involvement since his university days. Pictures showing Wagner injured, with two people assisting him, were published in many German newspapers. During later demonstrations, some protesters put red colour on their faces to symbolize Dietrich Wagner. Tristana Moore of
Time wrote that the photograph of his injury caused "a regional dispute over an unpopular building project instantly transformed into a national issue — and the political repercussions are now reverberating all the way to Berlin." According to the author
Jakob Augstein, the picture had a relevant impact on the March
2011 Baden-Württemberg state election, causing recently appointed Minister-President of Baden-Württemberg
Stefan Mappus to lose his position. In 2014 he visited the United Kingdom to ask
Theresa May, the
Home Secretary, to not authorise usage of water cannons. Wagner died on 28 June 2023, at the age of 79. ==References==
