<P> Tristan und Isolde ( Tristan and Isolde , or Tristan and Isolda , or Tristran and Ysolt ) is an opera , or music drama , in three acts by Richard Wagner to a German libretto by the composer , based largely on the romance by Gottfried von Strassburg . It was composed between 1857 and 1859 and premiered at the Königliches Hof - und Nationaltheater in Munich on 10 June 1865 with Hans von Bülow conducting . Wagner referred to the work not as an opera , but called it `` eine Handlung '' ( literally a drama , a plot or an action ) , which was the equivalent of the term used by the Spanish playwright Calderón for his dramas . </P>
