La bohème is based on Henri Murger's novel, Scènes de la vie de bohème, a collection of vignettes portraying young bohemians living in the Latin Quarter of Paris in the 1840s. Although usually called a novel, it has no unified plot. Like the 1849 play by Murger and 
Théodore Barrière, the opera's libretto focuses on the relationship between Rodolfo and Mimì, ending with her death. Also like the play, the libretto combines two characters from the novel, Mimì and Francine, into the single character of Mimì. Early in the composition stage Puccini was in dispute with the composer Leoncavallo, who said that he had offered Puccini a completed libretto and felt that Puccini should defer to him. Puccini responded that he had had no idea of Leoncavallo's interest and that having been working on his own version for some time, he felt that he could not oblige him by discontinuing with the opera. Leoncavallo completed his own version in which Marcello was sung by a tenor and Rodolfo by a baritone. It was unsuccessful and is now rarely performed.
