Agitprop It gave rise to agitprop theatre, a highly politicized left-wing theatre that originated in 1920s Europe and spread to the United States; the plays of Bertolt Brecht are a notable example.[5] Russian agitprop theater was noted for its cardboard characters of perfect virtue and complete evil, and its coarse ridicule.[6] Gradually the term agitprop came to describe any kind of highly politicized art.
