The famous playwright known for addressing political themes in their works is Bertolt Brecht. A significant figure in the 20th-century theater, Brecht's plays often critiqued societal norms and political ideologies. He is best known for developing the concept of epic theater, which aimed to provoke critical thought and social change by engaging the audience rather than simply entertaining them. Works like "Mother Courage and Her Children" exemplify his commitment to social justice and the power of the arts in political discourse.
