Edwardian musical comedy is a genre of British musical theatre that thrived from 1892 into the 1920s, extending beyond the reign of King Edward VII in both directions. It began to dominate the English musical stage, and even the American musical theatre, when the Gilbert and Sullivan operas' dominance had ended, until the rise of American musicals by Jerome Kern, Rodgers and Hart, George Gershwin and Cole Porter following the First World War.
Between In Town in 1892 and The Maid of the Mountains, premiering in 1917, this new style of musical theatre proliferated across the musical stages of Britain and the rest of the English-speaking world. The popularity of In Town and A Gaiety Girl (1893), led to an astonishing number of hits over the next three decades, into the 1920s, the most successful of which included The Shop Girl (1894), The Geisha (1896), Florodora (1899), A Chinese Honeymoon (1901), The Earl and the Girl (1903), The Arcadians (1909), Our Miss Gibbs (1909), The Quaker Girl (1910), Betty (1914), Chu Chin Chow (1916) and The Maid of the Mountains (1917).
