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.

The Viennese premiere of Orfeo was extremely well received, and Gluck decided to revise the opera as Orphée et Eurydice for Paris in 1774, with the French adaptation and additions provided by Pierre Louis Moline. The role of Orpheus was lowered slightly for an haute-contre singer (a male operatic voice type more in line with an alto range), adhering to French preferences. The opera was lengthened, to create a more magnificent spectacle, with extra arias, ensembles, and instrumental numbers. Gluck also modified the orchestration to accommodate the orchestra at the Académie Royale de Musique. This version, Orphée et Eurydice, became one of the most popular operas in France.

Sacchini’s first opera for the French stage was Renaud. Although he had the support of Marie Antoinette, Sacchini quickly learned that foreign (especially Italian) composers in Paris faced difficulties. The premiere of Renaud was intentionally delayed in an attempt to highlight Sacchini’s privilege with the queen, and the opera did not enjoy immediate success, even from Piccinni’s supporters. However, Renaud went on to be performed frequently, appearing as late as 1815.
