His plays deal with social and political issues
Shaw's major works from the first ten years of the twentieth century focused on moral, social, and personal themes. Man and Superman (1902), which presents Shaw's explanation of creative progress in a combination of theater and accompanying printed material, differs from the others in both content and treatment. Shaw's novel The Occupation of Cashel Byron, which includes the dramatic blank verse The Admirable Bashville (1901), focuses on the imperial connections between Britain and Africa. Although it was immensely popular at the time, John Bull's Another Island (1904), which hilariously portrayed the popular relationship between England and Ireland, was later removed from the standard repertory.
Major Barbara (1905) poses ethical issues in a novella that challenges the notion that the Salvation Army, when compared to a weapons manufacturer, always holds the moral high ground. Shaw referred to the play The Doctor's Dilemma (1906), which dealt with medical ethics and moral decisions regarding the distribution of limited resources for medical care. He was challenged by Archer to present a death on stage despite his reputation for playing improbable characters, which he achieved by staging a death scene in bed for the character of the anti-hero.
