Jargon theatre developed during the 19th century in the urban centers of Europe and flourished around the turn of the 20th century. Performed in a Yiddish-tinged mixed language, it provided popular entertainment on the basis of a specific humor that addressed social conflicts in the light of progressing modernization of the lebenswelt (world of lived experience). A paradigmatic example of jargon theatre was the theatre of the Herrnfeld brothers in Berlin.
