Konger is a Polish performance art group from Kraków, Poland, established in 1983 by a group of professional artists in protest against the imposition of Martial law in Poland. The artists boycotted all state galleries and took up performance art instead, an obsolete medium in the eyes of the official art critics. The Group was founded by Wladyslaw Kazmierczak, Artur Tajber, Marian Figiel and Marcin Krzyżanowski. Others included Kazimierz Madej and Peter Grzybowski. The activity was documented by Barbara Maroń.
