Knight in the context of "Knight of the Round Table"

The equites (/ˈɛkwɪtiːz/; lit. 'horse' or 'cavalrymen', though sometimes referred to as "knights" in English) constituted the second of the property/social-based classes of ancient Rome, ranking below the senatorial class. A member of the equestrian order was known as an eques (Latin: [ˈɛ.kʷɛs]).

Sir Peter Paul Rubens (/ˈruːbənz/ ROO-bənz; Dutch: [ˈpeːtər pʌul ˈrybəns]; 28 June 1577 – 30 May 1640) was a Flemish artist and diplomat. He is considered the most influential artist of the Flemish Baroque tradition. Rubens' highly charged compositions reference erudite aspects of classical and Christian history. His unique and immensely popular Baroque style emphasised movement, colour, and sensuality, which followed the immediate, dramatic artistic style promoted in the Counter-Reformation. Rubens was a painter producing altarpieces, portraits, landscapes, and history paintings of mythological and allegorical subjects. He was also a prolific designer of cartoons for the Flemish tapestry workshops and of frontispieces for the publishers in Antwerp.

Rubens was born and raised in the Holy Roman Empire (modern-day Germany) to parents who were refugees from Antwerp in the Duchy of Brabant in the Southern Netherlands (modern-day Belgium) and moved to Antwerp at about 12. In addition to running a large workshop in Antwerp that produced paintings popular with nobility and art collectors throughout Europe, Rubens was a classically educated humanist scholar and diplomat who was knighted by both Philip IV of Spain and Charles I of England. Rubens was a prolific artist. The catalogue of his works by Michael Jaffé lists 1,403 pieces, excluding numerous copies made in his workshop.

The Paladins, also called the Twelve Peers (French: Douze Pairs), are twelve legendary knights, the foremost members of Charlemagne's court in the 8th century. They first appear in the medieval (12th century) chanson de geste cycle of the Matter of France, where they play a similar role to the Knights of the Round Table in Arthurian romance. In these romantic portrayals, the chivalric paladins represent Christianity against a Saracen (Muslim) invasion of Europe. The names of the paladins vary between sources, but there are always twelve of them (a number with Christian associations) led by Roland (spelled Orlando in later Italian sources). The paladins' most influential appearance is in The Song of Roland, written between 1050 and 1115, which narrates the heroic death of Roland at the Battle of Roncevaux Pass.

The legend is based on the historical Umayyad invasion of Gaul and subsequent conflict in the Marca Hispanica between the Frankish Empire and the Emirate of Córdoba. The term paladin is from Old French, deriving from the Latin comes palatinus (count palatine), a title given to close retainers.

Freiherr (German: [ˈfʁaɪˌhɛɐ̯]; male, abbreviated as Frhr.), Freifrau ([ˈfʁaɪˌfʁaʊ]; his wife, abbreviated as Frfr., lit. 'free lord' or 'free lady') and Freiin ([ˈfʁaɪ.ɪn], his unmarried daughters and maiden aunts) are designations used as titles of nobility in the German-speaking areas of the Holy Roman Empire, the Austro-Hungarian Empire and in its various successor states, including Austria, Prussia, Bavaria, Liechtenstein, Luxembourg, etc. Traditionally, it denotes the titled rank within the nobility above Ritter (knight) and Edler (nobility without a specific title) and below Graf (count or earl). The title superseded the earlier medieval form, Edelherr.

It corresponds approximately to the English baron in rank. The Duden orthography of the German language references the French nobility title of Baron, deriving from the Latin-Germanic combination liber baro (which also means "free lord"), as corresponding to the German "Freiherr"; and that Baron is a corresponding salutation for a Freiherr.

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.

Pedro Calderón de la Barca y Barreda González de Henao Ruiz de Blasco y Riaño (17 January 1600 – 25 May 1681) (UK: /ˌkældəˈrɒn ˌdeɪ læ ˈbɑːrkə/, US: /ˌkɑːldəˈroʊn ˌdeɪ lə -, - ˌdɛ lə -/; Spanish: [ˈpeðɾo kaldeˈɾon de la ˈβaɾka]) was a Spanish dramatist, poet, and writer. He is known as one of the most distinguished poets and writers of the Spanish Golden Age, especially for the many verse dramas he wrote for the theatre. Calderón has been termed "the Spanish Shakespeare", the national poet of Spain, and one of the greatest poets and playwrights in the history of world literature.

Calderón de la Barca was born into the minor Spanish nobility in Madrid, where he lived for most of his life. He served as soldier and a knight of the military and religious Order of Santiago, but later became a Roman Catholic priest. His theatrical debut was a history play about the life of King Edward III of England, was first performed on 29 June 1623 at the Royal Alcázar of Madrid, during the surprise visit to Spain of Charles, Prince of Wales to negotiate for a dynastic marriage alliance with the Spanish Habsburgs.

A knight-errant (or knight errant) is a figure of medieval chivalric romance literature. The adjective errant (meaning "wandering, roving") indicates how the knight-errant would wander the land in search of adventures to prove his chivalric virtues, either in knightly duels (pas d'armes) or in some other pursuit of courtly love.

An overlord in the English feudal system was a lord of a manor who had subinfeudated a particular manor, estate or fee, to a tenant. The tenant thenceforth owed to the overlord one of a variety of services, usually military service or serjeanty, depending on which form of tenure (i.e. feudal tenancy contract) the estate was held under. The highest overlord of all, or lord paramount, was the monarch, who due to his ancestor William the Conqueror's personal conquest of the Kingdom of England, owned by inheritance from him all the land in England under allodial title and had no superior overlord, "holding from God and his sword", although certain monarchs, notably King John (1199–1216) purported to grant the Kingdom of England to Pope Innocent III, who would thus have become overlord to English monarchs.

A paramount lord may then be seen to occupy the apex of the feudal pyramid, or the root of the feudal tree, and such allodial title is also termed "radical title" (from Latin radix, root), "ultimate title" and "final title". William the Conqueror immediately set about granting tenancies on his newly won lands, in accordance with feudal principles. The monarch's immediate tenants were the tenants-in-chief, usually military magnates, who held the highest status in feudal society below the monarch. The tenants-in-chief usually held multiple manors or other estates from the monarch, often as feudal barons (or "barons by tenure") who owed their royal overlord an enhanced and onerous form of military service, and subinfeudated most to tenants, generally their own knights or military followers, keeping only a few in demesne. This created a mesne lord – tenant relationship. The knights in turn subinfeudated to their own tenants, creating a further subsidiary mesne lord – tenant relationship. Over the centuries for any single estate the process was in practice repeated numerous times.

A military order (Latin: Ordo militaris) is a Latin Catholic religious order of knights. The original military orders were the Knights Templar, the Knights Hospitaller, the Order of the Holy Sepulchre, the Order of Saint James, the Order of Calatrava, and the Teutonic Knights. They arose in the Middle Ages in association with the Crusades – the Crusader states (mainly the Kingdom of Jerusalem in the Holy Land), the Baltics, and the Iberian peninsula; their members being initially dedicated to the protection of Christian pilgrims, and eventually to the defence of the Crusader states and the conquest of non-Christian or even non-Catholic lands. They are the predecessors of chivalric orders.

Most members of military orders were laymen who took religious vows, such as of poverty, chastity, and obedience, according to monastic ideals. The orders owned houses called commanderies all across Europe and had a hierarchical structure of leadership with the grand master at the top.
