Interwar Germany was subject to intense political unrest. August Sander’s monumental photographic project ‘People of the 20th Century’ provides an invaluable source of historical documentation of some of the political trends of the time. Recording the atmosphere of social conflict and upheaval, Sander’s pictures illustrate the activities and events of those affiliated with both the political right and the left. This picture is one of a series of photographs that Sander took of street musicians. It is from the portfolio entitled ‘The Street and Street Life’, within the sixth group, ‘The City’. It shows a protest march by a group of people identified as part of ‘Der Rote Frontkämpferbund [Red Front Fighting League]’, the paramilitary arm of the German Communist Party founded in 1924 to counter the increasing power of National Socialist paramilitary groups. It was banned by the Prussian Ministry of the Interior in 1929, two years after this photograph was taken.
