Armide was premiered at the Paris Opéra on September 23, 1777, recalling the earlier success of Lully’s opera of the same name, which premiered nearly a century earlier on February 15, 1686. After collaborating on several reform operas with Calzabigi, Gluck revived the older dramatic tradition of Quinault (Lully's librettist) by setting the older text in the modern musical style. The seventeenth-century five act model requires more continuous music, with few distinct arias, as well as divertissements and spectacular effects. Gluck also respects the tragic conclusion endemic to the model, avoiding the modern practice of the lieto fine ("happy ending") in which misfortunes are reversed at the last possible moment.

Although he did not have a production planned, Gluck composed the music for Iphigénie en Aulide for Paris, with the intention (along with Roullet) of establishing himself at the Opéra. He initially had difficulties convincing the Academy of Music to arrange for the production, but with the support of Marie Antoinette, the opera was finally realized in 1773. Gluck revised Iphigénie for performances in 1775. The most significant change was the addition of Diana as a character, whose appearance serves as the deus ex machina of the plot. He also altered and expanded the divertissements.
