Cuirassiers (ˌkwɪrəˈsɪər; kɥiʁasje) were cavalry equipped with a cuirass, sword, and pistols. Cuirassiers first appeared in mid-to-late 16th century Europe as a result of armoured cavalry, such as men-at-arms and demi-lancers discarding their lances and adopting pistols as their primary weapon. In the later part of the 17th century, the cuirassier lost his limb armour and subsequently wore only the cuirass (breastplate and backplate), and sometimes a helmet. By this time, the sword or sabre had become his primary weapon, with pistols relegated to a secondary function. Cuirassiers achieved increased prominence during the Napoleonic Wars and were last fielded in the opening stages of World War I (1914–1918). A number of countries continue to use cuirassiers as ceremonial troops. The French term cuirassier means "one with a cuirass" ( cuirasse), the breastplate armour which they wore. The first cuirassiers were similar in appearance to the fully armoured Late Medieval man-at-arms. They wore three-quarter armour that covered the entire upper body as well as the front half of the legs down to the knee. The head was protected by a close helm, burgonet, or lobster-tailed pot helmet, usually worn with a gorget for the neck. The torso was protected by a breast and back plate, sometimes reinforced by a plackart. The arms and shoulders were fully armoured with pauldrons, rerebraces, elbow couters, and vambraces. Armoured gauntlets were often abandoned, particularly for the right hand, as they interfered with the loading of pistols. Long tassets, instead of a combination of short tassets with cuisses, protected the front of the thighs and knees, and riding boots were substituted for lower leg armour (greaves and sabatons). Weapons included a pair of pistols in saddle holsters (these were the primary weapons instead of a lance), a sword, and sometimes a "horseman's pick" (a type of war hammer). By the mid-16th century, Barding (horse armour) largely fell into dissue on the battlefield.
