Major Barbara, written in 1905, is a thought-provoking play by George Bernard Shaw that tackles issues of morality, capitalism, and religion. The plot centers on Barbara Undershaft, a Salvation Army major, and her estranged father, Andrew Undershaft, a wealthy arms manufacturer. When the Salvation Army accepts donations from her father, Barbara is forced to reconsider her moral beliefs. Shaw’s witty dialogue and sharp social critique challenge simplistic notions of good and evil, offering a nuanced exploration of power, poverty, and philanthropy.
