Spahis () were light-cavalry regiments of the French army recruited primarily from the Arab and Berber populations of Algeria, Tunisia and Morocco. The modern French Army retains one regiment of Spahis as an armoured unit, with personnel now recruited in mainland France. Senegal also maintains a mounted unit with spahi origins as a presidential escort: the Red Guard. Etymology The name is the French form of the Ottoman Turkish word , a word derived from New Persian , meaning "army", or "horsemen"; or from , meaning "warriors". Early history Following the French occupation of Algiers in 1830, detachments of locally recruited irregular horsemen were attached to the regiments of light cavalry assigned to North African service. These auxiliaries were designated as chasseurs spahis. Between 1834 and 1836 they were organised into four squadrons of regular spahis. In 1841 the 14 squadrons by then in existence were brought together in a single corps of spahis. Finally, in 1845 three separate Spahi regiments were created: the 1st of Algiers; the 2nd of Oran and the 3rd of Constantine. The spahi regiments saw extensive service in the French conquest of Algeria, in the Franco-Prussian War, in Tonkin towards the end of the Sino-French War (1885), in the occupation of Morocco and Syria, and in both World Wars. A detachment of Spahis served as the personal escort of Marshal Jacques Leroy de Saint Arnaud in the Crimean War and were photographed there by Roger Fenton. A contingent of Spahis also participated in the North China campaign of 1860. During the Franco-Prussian War of 1870-71 one detached squadrons of Spahis formed part of the forces defending Paris, while a provisional regiment comprising three squadrons was attached to the Army of the Loire. A serious uprising against French rule in Algeria during 1871–72 was sparked off by a mutiny of the 5th squadron of the 3rd Spahis, who had been ordered to France to reinforce those units already there. Under the Third Republic, between 1871 and 1914 Spahi units saw active service in Indochina, Tunisia, Morocco, Senegal and Madagascar. While a visually conspicuous presence in any French military force, the Spahis usually served in small detachments as scouts, skirmishers and escorts. An exception was the Battle of Isly (Morroco) in 1844 when the 1st and 2nd Spahis fought successfully as full regiments. Recruitment basis Prior to 1914 there were four regiments of Spahis in the French
