Les Misérables (/leɪ ˌmɪzəˈrɑːb(əl), -blə/ lay MIZ-ə-RAHB(-əl), -⁠RAH-blə, French: [le mizeʁabl]), colloquially known as Les Mis or Les Miz (/leɪ ˈmɪz/ lay MIZ), is a sung-through musical with music by Claude-Michel Schönberg, lyrics by Alain Boublil and Jean-Marc Natel, and a book by Boublil and Schönberg, based on the 1862 novel of the same name by Victor Hugo. Set in early 19th-century France, Les Misérables tells the story of Jean Valjean, a French convict, and his desire for redemption. After stealing a loaf of bread for his sister's starving child, Valjean is imprisoned for 19 years and released in 1815. When a bishop inspires him with a tremendous act of mercy, Valjean breaks his parole and starts his life anew and in disguise. He becomes wealthy and adopts an orphan, Cosette. A police inspector named Javert pursues Valjean over the decades in a single-minded quest for "justice". The characters are swept into a revolutionary period in France, where a group of young idealists attempts to overthrow the government at a street barricade in Paris.

The French musical premiered in Paris in 1980 with direction by Robert Hossein. Its English-language adaptation, with lyrics by Herbert Kretzmer, produced by Cameron Mackintosh and directed by Trevor Nunn and John Caird, has been running in London since October 1985, making it the longest-running musical in the West End and the second longest-running musical in the world after the original off-Broadway run of The Fantasticks. Many other long-running productions followed on Broadway and around the world, and a film adaptation was released in 2012.
