Document 3: Caesar and Cleopatra (play): Caesar and Cleopatra is a play written in 1898 by George Bernard Shaw that depicts a fictionalized account of the relationship between Julius Caesar and Cleopatra. It was first published with "Captain Brassbound's Conversion" and "The Devil's Disciple" in Shaw's 1901 collection "Three Plays for Puritans".

Document 4: John Bull's Other Island: John Bull's Other Island is a comedy about Ireland, written by George Bernard Shaw in 1904. Shaw himself was born in Dublin, yet this is one of only two plays of his where he thematically returned to his homeland, the other being "O'Flaherty V.C." The play was highly successful in its day, but is rarely revived, probably because so much of the dialogue is specific to the politics of the day.
Document 5: How He Lied to Her Husband: How He Lied to Her Husband is a one-act comedy play by George Bernard Shaw, who wrote it, at the request of actor Arnold Daly, over a period of four days while he was vacationing in Scotland in 1904. In its preface he described it as "a sample of what can be done with even the most hackneyed stage framework by filling it in with an observed touch of actual humanity instead of with doctrinaire romanticism." The play has often been interpreted as a kind of satirical commentary on Shaw's own highly successful earlier play "Candida" (which one of the characters gets tickets to see).
Document 6: The Doctor's Dilemma (play): The Doctor's Dilemma is a play by George Bernard Shaw first staged in 1906. It is a problem play about the moral dilemmas created by limited medical resources, and the conflicts between the demands of private medicine as a business and a vocation.
Document 7: The Devil's Disciple: The Devil's Disciple is an 1897 play written by Irish dramatist George Bernard Shaw. The play is Shaw's eighth, and after Richard Mansfield's original 1897 American production it was his first financial success, which helped to affirm his career as a playwright. It was published in Shaw's 1901 collection "Three Plays for Puritans" together with "Captain Brassbound's Conversion" and "Caesar and Cleopatra". Set in Colonial America during the Revolutionary era, the play tells the story of Richard Dudgeon, a local outcast and self-proclaimed "Devil's disciple". In a twist characteristic of Shaw's love of paradox, Dudgeon sacrifices himself in a Christ-like gesture despite his professed Infernal allegiance.
Document 8: Candida (play): Candida, a comedy by playwright George Bernard Shaw, was written in 1894 and first published in 1898, as part of his "Plays Pleasant". The central characters are clergyman James Morell, his wife Candida and a youthful poet, Eugene Marchbanks, who tries to win Candida's affections. The play questions Victorian notions of love and marriage, asking what a woman really desires from her husband. The cleric is a Christian Socialist, allowing Shaw—himself a Fabian Socialist—to weave political issues, current at the time, into the story.

Document 10: The Importance of Being Earnest: After the success of Wilde's plays Lady Windermere's Fan and A Woman of No Importance, Wilde's producers urged him to write further plays. In July 1894 he mooted his idea for The Importance of Being Earnest to George Alexander, the actor - manager of the St James's Theatre. Wilde spent the summer with his family at Worthing, where he wrote the play quickly in August. His fame now at its peak, he used the working title Lady Lancing to avoid pre-emptive speculation of its content. Many names and ideas in the play were borrowed from people or places the author had known; Lady Queensberry, Lord Alfred Douglas's mother, for example, lived at Bracknell. There is widespread agreement among Wilde scholars that the most important influence on the play was W.S. Gilbert's 1877 farce Engaged; Wilde borrowed from Gilbert not only several incidents but, in Russell Jackson's phrase ``the gravity of tone demanded by Gilbert of his actors ''.
