The work is generally regarded as a major contribution towards the development of Czech music.  It was composed during the period 1863–66, and first performed at the Provisional Theatre, Prague, on 30 May 1866 in a two-act format with spoken dialogue.    is a '"festival opera" in three acts, with music by Bedřich Smetana.  The libretto was originally written in German by Josef Wenzig, and was then translated into Czech by Ervin Špindler.  In Czech historical myth, Libuše, the title character, prophesied the founding of Prague.  The opera was composed in 1871–72 for the coronation of Franz Josef as Czech king.  This did not happen and Smetana saved "Libuše" for the opening of the National Theatre in Prague, which took place nine years later on 11 June 1881.  After the destruction of the National Theatre in a fire, the same opera opened the reconstructed theatre in 1883.  The first US performance was reported to have occurred March 1986, in a concert version at Carnegie Hall with Eve Queler and the Opera Orchestra of New York.

The Prague Provisional Theatre (, ] ) was erected in 1862 as a temporary home for Czech drama and opera until a permanent National Theatre could be built.  It opened on 18 November 1862 and functioned for 20 years, during which time over 5,000 performances were presented.  Between 1866 and 1876 the theatre staged the premieres of four of Bedřich Smetana's operas, including "The Bartered Bride".

While it is often presented as a single work in six movements and – with the exception of "Vltava" – is almost always recorded that way, the six pieces were conceived as individual works.  They had their own separate premieres between 1875 and 1880; the premiere of the complete set took place on 5 November 1882 in Žofín Palace, Prague, under Adolf Čech, who had also conducted two of the individual premieres.
