The importance of being earnest was the last play written by Oscar Wilde. It was known as “A Trivial Comedy for Serious People”. First performed on 14 February 1895 at St. James's Theatre in London, the play is a ridiculous comedy in which the protagonists keep fictitious characters in order to escape of their obligations.
Jack Worthing, the play’s protagonist, lives in Hertfordshire, where he is guardian to Cecily Cardew. Jack lives a double life, in the country he assumes a serious attitude for the benefit of Cecily, and goes by the name of Jack, while he says he must worry about an irresponsible brother named Ernest in London. In the city he assumes the identity of the libertine Ernest. In fact, no one but Jack knows that he is Ernest.
