Shakespeare's audiences were familiar with the historical personages portrayed and the political situation in Europe relating to the setting and action of the play. Scholars suggest the play lost popularity as these historical and political portrayals of Navarre's court became dated and less accessible to theatergoers of later generations. The play's sophisticated wordplay, pedantic humour and dated literary allusions may also be cause for its relative obscurity, as compared with Shakespeare's more popular works. "Love's Labour's Lost" was rarely staged in the 19th century, but it has been seen more often in the 20th and 21st centuries, with productions by both the Royal Shakespeare Company and the National Theatre, among others. It has also been adapted as a musical, an opera, for radio and television and as a musical film.
