Thank you Jonas. These helmets were used in the latter half of the 19th century. These were made in France for the Khedive, the de facto ruler of Egypt. The word essentially would be the same as "Viceroy" and was a term adopted by Muhammad Ali Pasha - who became the semi-autonomous (independent) ruler of Egypt yet still a vassal to the Ottoman Empire.
The backstory is that during Napoleon's invasion of Egypt the ruling Mamluk military caste was defeated - and the Ottoman's sent troops from the Balkans led by Muhammad Ali Pasha (a Muslim from Albania). Muhammad Ali seized control of the country, and declared himself ruler of Egypt, quickly consolidating an independent local powerbase. The Ottomans attempted to have him killed, but when that failed the Sublime Porte in Constantinople officially recognized Muhammad Ali as Pasha and Wāli (Governor) of Egypt. Muhammad Ali declared himself "Khedive," a title adopted by his successors and then recognized by the Ottomans.
So that is how the title and rule came about. Under the Khedive the semi-autonomous state of Egypt allowed the French and British to build the Suez Canal, and during this time Cairo became a more modern city. It had street lights before Paris, upgraded the sewers and generally was becoming more "European" influenced. With this influence from France the Khedive adopted more Western style uniforms and this included this style of helmet.
It was used from the 1860s to circa 1900.
