It was first produced at the Théâtre-Italien in Paris on 19 December 1828.
Clari was based on a popular novella, the storyline of which had already been set as an opera by Henry Bishop in London in 1823 (Clari, or the Maid of Milan - it included what came to be Bishop's most famous song, Home! Sweet Home!). There had also been a production of the story as Clari ou la promesse de mariage as a 'ballet-pantomime' in three acts at the Paris Opéra in 1820, with music by Rodolphe Kreutzer and designs by Cicéri and Louis Daguerre.
Halévy was chef de chant (vocal coach) at the Théâtre-Italien when he wrote the opera, his first in the Italian language. Clari's entrance aria in Act I, Come dolce a me favelli, had been in fact written by him in Italy some five or six years earlier as a fulfilment of his requirements when he had won the Prix de Rome.
Although Halévy was able to secure Maria Malibran for the title role, the work failed to please the public and was taken off after six performances. Fromental's brother, Ludovic, in his biography of the composer, however refers to Malibran's performance as 'so moving and dramatic'. A few further performances were given, of a revised version, in 1830.
The opera was not revived for nearly 180 years when Cecilia Bartoli took the role of Clari in a production given by the Opernhaus Zürich in 2008 in celebration of the centenary of Malibran's birth.
