The existing repertoire of Scottish-themed plays included John Home's "Douglas" (1756) and Ramsay's "The Gentle Shepherd" (1725), with the last two being the most popular plays among amateur groups. Scott was keenly interested in drama, becoming a shareholder in the Theatre Royal, Edinburgh. Baillie's Highland themed "Family Legend" was first produced in Edinburgh in 1810 with the help of Scott, as part of a deliberate attempt to stimulate a national Scottish drama. Scott also wrote five plays, of which "Hallidon Hill" (1822) and "MacDuff's Cross" (1822), were patriotic Scottish histories. Adaptations of the Waverley novels, largely first performed in minor theatres, rather than the larger Patent theatres, included "The Lady in the Lake" (1817), "The Heart of Midlothian" (1819), and "Rob Roy", which underwent over 1,000 performances in Scotland in this period. Also adapted for the stage were "Guy Mannering", "The Bride of Lammermoor" and "The Abbot". These highly popular plays saw the social range and size of the audience for theatre expand and helped shape theatre-going practices in Scotland for the rest of the century.
