Why did eminent critics sharply reject some war poems? Why did critics and war poets mention opposition between the home and the battle front? Why was the mass of war veterans so disquieted after the war to stand behind the swift of diverse Fascist movements in various European countries?

Why did war poems question the received notions of the socially acceptable? This study explores change in its most abrupt form, which spared nothing raising from the ashes of the unrepentant Belle Epoque positivism. From gender relations to societal fabric and emotional, financial and bodily integrity: the foundation of European civilization was at stake.
