Sir Robert Chiltern, Baronet, Under-Secretary for Foreign Affairs
Sir Robert Chiltern is the protagonist of the play, a forty-year-old politician in the House of Commons, caught in a blackmail plot to ruin him. As a young man he was secretary to Lord Radley and sold information to Baron Arnheim allowing him to make a fortune on the Suez Canal. The Baron tempted him with a philosophy of power, and Sir Robert could not get into politics without money, so he took a bribe and got rich. Now he is quite famous and respectable, and when Mrs. Cheveley wants him to support the Argentine Canal scheme he is about to give in to her demand until his wife forces him to refuse her. He denounces the scheme thinking he will be exposed as a fraud, but he is saved by his friend, Lord Goring. Sir Robert is nervous and tense. He takes his career seriously as a liberal politician bent on reform. He is practical, however, and believes there is nothing morally wrong with making deals to get power. He is in love with his wife and afraid of losing her love and regard over his secret past.
Lord Goring, Sir Robert’s friend Arthur, is a thirty-four-year-old society bachelor who is idle and enjoys his full-time social life. He was once engaged to Mrs. Cheveley and though she tries to blackmail him into marrying her to save Sir Robert, he counter blackmails her by threatening to have her arrested for the theft of the diamond brooch she wears. Arthur is a good friend of the Chilterns and gives wise advice to them in their crisis. Though he seems an idle fool, he is balanced and practical, knowing how to negotiate with the world on its own terms.

They do not take life too seriously, yet he is the one who preaches love, forgiveness, and tolerance.
