Misalliance is a play written in 1909–1910 by George Bernard Shaw. The play takes place entirely on a single Saturday afternoon in the conservatory of a large country house in Hindhead, Surrey in Edwardian era England. It is a continuation of some of the ideas on marriage that he expressed in 1908 in his play, Getting Married. It was also a continuation of some of his other ideas on Socialism, physical fitness, the Life Force, and "The New Woman": i.e. women intent on escaping Victorian standards of helplessness, passivity, stuffy propriety, and non-involvement in politics or general affairs. Misalliance is an ironic examination of the mating instincts of a varied group of people gathered at a wealthy man's country home on a summer weekend. Most of the romantic interest centers on the host's daughter, Hypatia Tarleton, a typical Shaw heroine who exemplifies his lifelong theory that in courtship, women are the relentless pursuers and men the apprehensively pursued.
