The Pirate Queen is a musical with music by Claude-Michel Schönberg, French lyrics by Alain Boublil and English lyric adaptations by Richard Maltby, Jr. and John Dempsey. The French book was written by Boublil and Schönberg and the English book adaptation was by Maltby, Jr. Based on Grania: She-King of the Irish Seas by Morgan Llywelyn, The Pirate Queen marks the first time Boublil and Schönberg have created a musical with American collaborators. It is based on the life and adventures of the 16th century Irish chieftain and pirate Gráinne O’Malley, who was one of the last Irish clan leaders to resist the English conquest of Gaelic Ireland. After a Chicago tryout production in 2006, the musical opened on Broadway on April 5, 2007 after 32 previews. It closed on June 17, 2007 after 85 performances.
