The term "Angry Young Men" refers to a group of British writers and playwrights in the 1950s who expressed discontent with societal norms and the establishment. They often portrayed the struggles of the working class and critiqued the complacency of post-war British society. Notable figures include John Osborne, Kingsley Amis, and Alan Sillitoe. These writers used their works to voice frustration over issues like class inequality and lack of opportunity. Their literature often featured protagonists who were disillusioned and rebellious, reflecting a broader cultural shift towards questioning authority and traditional values in the wake of World War II.
