Les Misérables (; French pronunciation: [le mizeʁabl(ə)]), colloquially known in English-speaking countries as Les Mis (), is a sung-through musical adapted from French poet and novelist Victor Hugo's 1862 novel of the same name by Claude-Michel Schönberg (music), Alain Boublil and Jean-Marc Natel (original French lyrics), and Herbert Kretzmer (English lyrics). The original French musical premiered in Paris in 1980 with direction by Robert Hossein. Its English-language adaptation by producer Cameron Mackintosh 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.
Set in early 19th-century France, Les Misérables is the story of Jean Valjean, a French peasant, and his desire for redemption after serving nineteen years in jail for having stolen a loaf of bread for his sister's starving child. Valjean decides to break his parole and start his life anew after a bishop inspires him by a tremendous act of mercy, but he is relentlessly tracked down by a police inspector named Javert. Along the way, Valjean and a slew of characters are swept into a revolutionary period in France, where a group of young idealists attempt to overthrow the government at a street barricade.
