The Haymarket Theatre opened in late 1720, only to struggle financially for its first several years. In the 1730s, Henry Fielding staged a series of satires parodying prime minister Robert Walpole. These pieces drew audiences, but they also enraged Walpole sufficiently to prompt him to engineer passage of the Stage Licensing Act of 1737, which initiated the censorship of British drama that continued through most of the twentieth century.
