konkret has been the name of two German magazines.
konkret was originally the name of a magazine established by Klaus Rainer Röhl in 1957, that was an influential magazine on the German political left in the 1960s. The magazine was dissolved in 1973 as a consequence of Röhl's rejection of the leftist terrorism in Germany (in which his former wife Ulrike Meinhof took active part).
Since 1974, Hermann L. Gremliza has published a monthly magazine with the same name, self-described as a "magazine for politics and culture". The current magazine is significantly less influential than the original konkret magazine and part of the far-left fringe. It is described as leftist extremist by the Federal Office for Protection of the Constitution and also as Anti-German by the State Office for Protection of the Constitution in North Rhine-Westphalia.
In 1955, Klaus Rainer Röhl started the monthly Studentenkurier ("Student Messenger"), which was published until 1957. Due to the contributions of many authors as Werner Riegel, Peter Rühmkorf, Arno Schmidt, Kurt Hiller, it became a very influential magazine among students.
On the basis of the success of the Studentenkurier, Konkret was founded by Röhl in 1957. Until 1964, it had clandestine ideological and financial relations with the East German government. Innovative in its style, beautifully illustrated and printed on huge folio size heavy stock, its pages often ended up as posters on students' dorm walls and university campus fences. It had great influence on progressive intellectuals, both students and adults. In the high phase of the German student movement of the 1960s, it appeared biweekly and sometimes even weekly.
