Warrior in the context of "Spartan army"

Historically, cavalry (from the French word cavalerie, itself derived from cheval meaning "horse") are groups of soldiers or warriors who fight mounted on horseback. Until the 20th century, cavalry were the most mobile of the combat arms, operating as light cavalry in the roles of reconnaissance, screening, and skirmishing, or as heavy cavalry for decisive economy of force and shock attacks. An individual soldier in the cavalry is known by a number of designations depending on era and tactics, such as a cavalryman, horseman, trooper, cataphract, knight, drabant, hussar, uhlan, mamluk, cuirassier, lancer, dragoon, samurai or horse archer. The designation of cavalry was not usually given to any military forces that used other animals or platforms for mounts, such as chariots, camels or elephants. Infantry who moved on horseback, but dismounted to fight on foot, were known in the early 17th to the early 18th century as dragoons, a class of mounted infantry which in most armies later evolved into standard cavalry while retaining their historic designation.

Cavalry had the advantage of improved mobility, and a soldier fighting from horseback also had the advantages of greater height, speed, and inertial mass over an opponent on foot. Another element of horse mounted warfare is the psychological impact a mounted soldier can inflict on an opponent.

Chivalry, or the chivalric language, is an informal and varying code of conduct that developed in Europe between 1170 and 1220. It is associated with the medieval Christian institution of knighthood, with knights being members of various chivalric orders, and with knights' and gentlemen's behaviours which were governed by chivalrous social codes. The ideals of chivalry were popularized in medieval literature, particularly the literary cycles known as the Matter of France, relating to the legendary companions of Charlemagne and his men-at-arms, the paladins, and the Matter of Britain, informed by Geoffrey of Monmouth's Historia Regum Britanniae, written in the 1130s, which popularized the legend of King Arthur and his knights of the Round Table.

The code of chivalry that developed in medieval Europe had its roots in earlier centuries. It arose in the Carolingian Empire from the idealisation of the cavalryman—involving military bravery, individual training, and service to others—especially in Francia, among horse soldiers in Charlemagne's cavalry. Over time, the meaning of chivalry in Europe has been refined to emphasize more general social and moral virtues. The code of chivalry, as it stood by the Late Middle Ages, was a moral system which combined a warrior ethos, knightly piety, and courtly manners, all combining to establish a notion of honour and nobility.

Rājpūt (IPA: [ɾaːd͡ʒpuːt̪], from Sanskrit rājaputra meaning "son of a king"), also called Thākur (IPA: [ʈʰaːkʊɾ]), is a large multi-component cluster of castes, kin bodies, and local groups, sharing social status and ideology of genealogical descent originating from the northern part of the Indian subcontinent. However, the derivation from rājaputra is misleading because although many Rajputs belonged to some ruling clans, the majority of the Rajput community were common agricultural laborers whose main source of income was farming. The term Rajput covers various patrilineal clans historically associated with warriorhood: several clans claim Rajput status, although not all claims are universally accepted. According to modern scholars, almost all Rajput clans originated from peasant or pastoral communities.

Over time, the Rajputs emerged as a social class comprising people from a variety of ethnic and geographical backgrounds. From the 12th to 16th centuries, the membership of this class became largely hereditary, although new claims to Rajput status continued to be made in later centuries. Several Rajput-ruled kingdoms played a significant role in many regions of central and northern India from the seventh century onwards.

Xiang Yu (c. 232 – c. January 202 BC), born Xiang Ji, was a Chinese warlord who founded and led the short-lived kingdom-state of Western Chu during the interregnum period between the Qin and Han dynasties known as the Chu–Han Contention (206–202 BC). A nobleman of the former state of Chu, Xiang Yu rebelled against the Qin dynasty under the command of his uncle Xiang Liang, and was granted the title of "Duke of Lu" (魯公) by King Huai II of the restoring Chu state in 208 BC. The following year, he led an outnumbered Chu army to victory at the Battle of Julu against the Qin armies led by Zhang Han. After the fall of Qin, Xiang Yu divided the country into a federacy of Eighteen Kingdoms, among which he was self-titled as the "Hegemon-King of Western Chu" (西楚霸王) and ruled a vast region spanning central and eastern China, with Pengcheng as his capital.

Although a formidable warrior and tactician, Xiang Yu was poor in both diplomacy and strategy, especially after dismissing his own adviser Fan Zeng. He was later outcompeted by his main rival Liu Bang during the massive civil war among the rebel kingdoms, which concluded with his eventual defeat and suicide in a last stand at the Battle of Gaixia. The demise of Xiang Yu allowed Liu Bang to subsequently become the founding emperor of the newly established Han dynasty, which is widely regarded as a golden age in Chinese history.

Kshatriya (Sanskrit: क्षत्रिय, romanized: Kṣatriya) (from Sanskrit kṣatra, "rule, authority"; also called Rajanya) is one of the four varnas (social orders) of Hindu society and is associated with the warrior aristocracy. The Sanskrit term kṣatriyaḥ is used in the context of later Vedic society wherein members were organised into four classes: brahmin, kshatriya, vaishya, and shudra.

Camel cavalry, or camelry (French: méharistes, pronounced [meaʁist]), is a generic designation for armed forces using camels as a means of transportation. Sometimes warriors or soldiers of this type also fought from camel-back with spears, bows, or firearms.

Camel cavalry was a common element in desert warfare throughout history in the Middle East, due in part to the animals' high level of adaptability. They were better suited to working and surviving in arid environments than the horses of conventional cavalry. The smell of the camel, according to Herodotus, alarmed and disoriented horses, making camels an effective anti-cavalry weapon of the Achaemenid Persians in the Battle of Thymbra.
