The premiere production of Le ca√Įd by the Op√©ra-Comique was conducted by Th√©ophile Tilmant and directed by Ernest Mocker.  The opera received very favourable reviews and was Thomas's first major popular success.  The work evinced a vogue for all things Algerian in the colonial power of France, which had conquered Algeria in 1830.  It was revived by the Op√©ra-Comique on 31 August 1851, when it was given its 100th performance with Caroline Miolan-Carvalho as Virginie.  It was last revived by the Op√©ra-Comique on 16 February 1911, receiving a total of 422 representations by that company,  and was revived at the Ga√ģt√©-Lyrique on 18 May 1931.  Its most recent revival was in November 2007 when it was staged at the Op√©ra-Th√©√Ętre in Metz in a production designed and directed by Adriano Sinivia and conducted by Jacques Mercier. 
Outside France the opera was first performed in Brussels on 26 August 1849,  in London at St. James's Theatre on 8 February 1850,  and in New Orleans at the Th√©√Ętre d'Orl√©ans on 18 April 1850.  It was given in English at the Haymarket Theatre in London on 18 June 1851 (as The Cadi, or Amours among Moors  ) and in Manchester on 8 December 1880. It was performed in German in Vienna in 1856, Berlin in 1857, and Prague in 1860, and in Italian in Milan in 1863, Barcelona in 1865, Florence in 1877, and Naples in 1889.

Aboul-y-far, the ca√Įd of an Algerian town under French control, is regularly beaten up by his subjects in protest against the taxes and fines that he imposes on them. Birotteau, a French hairdresser with a shop in the town, approaches the ca√Įd with the offer of a "secret talisman" which will protect him from the depredations of his subjects. The price is 20,000 boudjous. The ca√Įd, a notorious miser, offers him his daughter Fathma's hand in marriage instead. Birotteau is flattered by the proposal and accepts the offer, forgetting that he is already engaged to Virginie, who owns a millinery shop in the town.
Meanwhile, the ca√Įd's steward and factotum, Ali-Bajou, has a different plan afoot to protect his master. He fosters a passionate romance between Fathma and Michel, the drum-major of the occupying French army. When Michel and Virginie hear of Birotteau's deal with the ca√Įd, they are furious. Faced with Virginie's vow of vengeance and Michel's threat to cut his ears off, Birotteau refuses to marry Fathma in exchange for the "secret talisman" after all. The ca√Įd reluctantly pays Birotteau the 20,000 boudjous, only to discover that the talisman is a recipe for a hair pomade which purportedly cures baldness. In the end, Ali-Bajou becomes happily drunk on French wine. Virginie are Birotteau are married, as are Fathma and Michel. Michel becomes the ca√Įd's bodyguard, and the ca√Įd's only regret is that whole affair has cost him 20,000 boudjous.
The opera was admired by the French composers Hector Berlioz and Georges Bizet. as well as the French poet Th√©ophile Gautier.   Some other taste-setters had some reservations. F√©lix Cl√©ment and Pierre Larousse in their 1869 Dictionnaire lyrique described Le ca√Įd as follows:
It cannot be denied that this work is amusing and the music very agreeable. Nevertheless, in our view, the whole has a touch of vulgarity about it, a familiarity and parody which is not part of the opera-buffa. nor of the old op√©ra-comique. The score teems with charming melodies. In the harmony, under a piquant exterior, lie the purest and most learned forms; the instrumentation is ravishing. So from where does this impression come that we have spoken of above? It is likely due to the disparity of costume and theatrical genre, that people of taste saw with pain ever increasingly popular in France, pieces in which no true sentiment is taken seriously, and the spectator finds no respite from the buffooneries and stunts [cascades ] of the actors. A continual alliance of the most noble of the arts with the weak sides of human character seems to us regrettable.
