The Mikado, a light opera by W. S. Gilbert and Arthur Sullivan, receives its first public performance at the Savoy Theatre in London.

The Mikado; or, The Town of Titipu is a comic opera in two acts, with music by Arthur Sullivan and libretto by W. S. Gilbert, their ninth of fourteen operatic collaborations. It opened on 14 March 1885, in London, where it ran at the Savoy Theatre for 672 performances, the second-longest run for any work of musical theatre and one of the longest runs of any theatre piece up to that time. By the end of 1885, it was estimated that, in Europe and America, at least 150 companies were producing the opera.

Sir William Schwenck Gilbert was an English dramatist, librettist, poet and illustrator best known for his collaboration with composer Arthur Sullivan, which produced fourteen comic operas. The most famous of these include H.M.S. Pinafore, The Pirates of Penzance and one of the most frequently performed works in the history of musical theatre, The Mikado. The popularity of these works was supported for over a century by year-round performances of them, in Britain and abroad, by the repertory company that Gilbert, Sullivan and their producer Richard D'Oyly Carte founded, the D'Oyly Carte Opera Company. These Savoy operas are still frequently performed in the English-speaking world and beyond.

Sir Arthur Seymour Sullivan was an English composer. He is best known for 14 operatic collaborations with the dramatist W. S. Gilbert, including H.M.S. Pinafore, The Pirates of Penzance and The Mikado. His works include 24 operas, 11 major orchestral works, ten choral works and oratorios, two ballets, incidental music to several plays, and numerous church pieces, songs, and piano and chamber pieces. His hymns and songs include "Onward, Christian Soldiers" and "The Lost Chord".
