A number of cross symbols were developed for the purpose of the emerging system of heraldry, which appeared in Western Europe in about 1200. This tradition is partly in the use of the Christian cross an emblem from the 11th century, and increasingly during the age of the Crusades. Many cross variants were developed in the classical tradition of heraldry during the late medieval and early modern periods. Heraldic crosses are inherited in modern iconographic traditions and are used in numerous national flags.
History The Christian cross emblem (Latin cross or Greek cross) was used from the 5th century, deriving from a T-shape representing the gibbet (stauros, crux) of the crucifixion of Jesus in use from at least the 2nd century. The globus cruciger and the staurogram is used in Byzantine coins and seals during the Heraclian period (6th century). Under the Heraclian dynasty (7th century), coins also depict simply crosses potent, patty, or pommy.
The cross was used as a field sign by the Christian troops during the Crusades. In 1188, Kings Henry II of England and Philip II of France agreed to launch the Third Crusade together, and that Henry would use a white cross and Philip a red cross. The red-on-white cross came to be used by the Knights Templar, and the white-on-red one by the Knights Hospitaller (also white-on-black); the Teutonic Order used a black-on white version. Early cross or spiral-like shield decorations, not necessarily with Christian symbolism, are already found on depictions of shields of the 11th century.Round Shield Designs (vikingage.org): "simple cross": Bayeux Tapestry, "flared cross" Arras, BM MS 559 (435), vol. 1 (c. 1000–1050).
Heraldry emerged in western Europe at the start of the 13th century out of earlier traditions. The basic variants of the red-on-white (termed the Cross of Saint George) and the white-on-red crusaders' cross were continued independently in the flags of various states in the 13th and 14th century, including the Duchy of Genoa, the Electorate of Trier, the Bishopric of Constance and the Kingdoms of England and Georgia, which last two had special devotions to St George on one hand;Red crosses seem to have been used as a distinguishing mark worn by English soldiers from the reign of Edward I (1270s). Perrin (1922) concludes that the introduction of the Cross of St George as a "national emblem" is originally due to Edward I. By 1300, there was also a greater "banner of St George", but not yet in a prominent function; the king used it among several banners of saints alongside the royal banner. "Among the greater banners that of St George was not as yet supreme; it was indeed only one of four, for when the Castle of Carlaverock was taken in the year 1300: [...]" Perrin 1922, p. 37 "The first step towards the promotion of St George to a position of predominance seems to be due to Edward III, who in gratitude for his supposed help at the Battle of Cregy founded the Chapel of St George at Windsor in 1348." Perrin 1922, pp. 37f. Perrin (1922), British Flags, p. 37 and Savoy, the war flag of the Holy Roman Empire and (possibly from the latter) Switzerland and Denmark on the other.
The cross appears as heraldic charge in the oldest rolls of arms, from about 1250. A roll of arms of the 13th century (the reign of Henry III of England) lists the coats of arms of various noblemen distinguished by crosses of different tinctures: (viz. red on gold); (white on red): this is attributed, Peter's funerary monument displays an eagle on his shield; (red on white). Glover's Roll (British Library Add MS 29796), a 16th-century copy of a roll of arms of the 1250s has depictions of various heraldic crosses, including the or a cross gules of the earl of Norfolk, gules, a cross argent of Peter of Savoy, argent a cross gules of Robert de Veer, gules a cross flory vair of Guillaume de Forz, Comte d'Aumale, gules a cross fleury argent of Guillaume Vescy, gules a cross saltire engrele of Fulke de Escherdestone, argent a cross fleury azure of John Lexington, azure three crosses or of William de Sarren, or a cross gules, five scallops argent of Ralph Bigod, gules a cross fourchy argent of Gilbert de Vale, argent a cross fleury sable of John Lamplowe, or a cross saltire gules, a chief gules of Robert de Brus, gules a cross saltire argent of Robert de Neville, or a cross voided gules of Hamond (Robert) de Crevecoeur, and azure a cross or, four lions rampant or of Baudouin Dakeney. In addition, the Glover Roll has semy of crosses crosslet as a tincture in several coats of arms.
The desire to distinguish one's coat of arms from others led to a period of substantial innovation in producing variants of the basic Christian cross by the early 14th century (in England, the reign of Edward II).
The great number of variants of crosses, and the deep history of such variants (going back to the 14th century or earlier) results in confusing and often contradictory terminology."heraldic writers have in their ingenuity multiplied the forms. In giving a summary of the chief forms only we are met with the difficulty of many synonyms occurring, for practically the same form is often much varied by incorrect drawing, and much confusion has arisen from blunders of heraldic writers in misreading or misunderstanding the terms employed. The French terms are more varied still than the English, and the correlation of the two series can only be attempted approximately." James Parker, A Glossary of Terms Used in Heraldry (1894)
In the heraldry of the Holy Roman Empire, the cross is comparatively rare in the coats of arms of noble families, presumably because the plain heraldic cross was seen as an imperial symbol (for the same reason, the eagle was rarely used as a charge because it represented the empire), but in the 14th century the plain cross is used in the seals and flags of several prince-bishoprics, including Trier, Constance and Cologne.The 14th-century Zürich armorial has no family coats of arms with crosses, but shows plain crosses in the flags of several cities, including Constance, Speier, Trier and Mainz.
Looking back on the Crusades as the foundational period of knighthood, the badge of the cross became strongly associated with the idealized Christian knight of romance, as expressed by Spenser (Faerie Queene book 1, canto 1): Retrieved February 27, 2016
The black-on-white cross worn by the Teutonic Knights was granted by Innocent III in 1205. The coat of arms representing the grand master (Deutschmeisterwappen)The offices of Hochmeister (grand master, head of the order) and Deutschmeister (Magister Germaniae) were united in 1525. The title of Magister Germaniae had been introduced in 1219 as the head of the bailiwicks in the Holy Roman Empire, from 1381 also those in Italy, raised to the rank of a prince of the Holy Roman Empire in 1494, but merged with the office of grand master under Walter von Cronberg in 1525, from which time the head of the order had the title of Hoch- und Deutschmeister. Bernhard Peter (2011) is shown with a golden cross fleury or cross potent superimposed on the black cross, with the imperial eagle as a central inescutcheon. The golden cross fleury overlaid on the black cross becomes widely used in the 15th century. A legendary account attributes its introduction to Louis IX of France, who on 20 August 1250 granted the master of the order this cross as a variation of the Jerusalem cross, with the fleur-de-lis symbol attached to each arm. While this legendary account cannot be traced back further than the early modern period (Christoph Hartknoch, 1684) there is some evidence that the design does indeed date to the mid 13th century.Helmut Nickel, "Über das Hochmeisterwappen des Deutschen Ordens im Heiligen Lande", Der Herold 4/1990, 97–108 (mgh-bibliothek.de).

"Die zeitgenössische Überlieferung verdeutlicht für dieses Wappen hingegen einen anderen Werdegang. Der Modelstein eines Schildmachers, der unter Hermann von Salza zwischen 1229 und 1266 auf der Starkenburg (Montfort) im Heiligen Land tätig war, und ein rekonstruiertes Deckengemälde in der Burgkapelle derselben Festung erlaubten der Forschung den Schluss, dass sich die Hochmeister schon im 13. Jahrhundert eines eigenen Wappens bedient hätten. Es zeigte ein auf das schwarze Ordenskreuz aufgelegtes goldenes Lilienkreuz mit dem bekannten Adlerschildchen. Die Wappensiegel des Elbinger Komturs von 1310 bzw. 1319, ein heute in Innsbruck aufbewahrter Vortrageschild des Hochmeisters Karl von Trier von etwa 1320 und das schlecht erhaltene Sekretsiegel desselben Hochmeisters von 1323 sind ebenfalls jeweils mit aufgelegtem goldenem Lilienkreuz ausgestattet." The black cross patty was later used for military decoration and insignia by the Kingdom of Prussia and gave rise to the cross patty in the German Reichskriegsflagge and the Iron Cross and Pour le Mérite orders.
The Nordic cross is an 18th-century innovation derived from cross flags adapted as swallow-tailed (or triple-tailed) pennons used as civil ensigns; the first official introduction of such a flag was in a regulation of 11 June 1748 describing the Danish civil ensign (Koffardiflaget) for merchant ships. The Danish design was adopted for the flags of Norway (civil ensign 1821) and Sweden (1906), both derived from a common ensign used during the Union between Sweden and Norway 1818–1844, Iceland (1915) and Finland (1917).
Ordinary cross
The blazon Cross without any addition signifies a heraldic ordinary, a pale and a fess of equal widths conjoined, the width being typically one-fifth of the shield (or one third of the shield when charges are placed on the cross).James Parker, A Glossary of Terms Used in Heraldry (1894). The four arms should be of equal length (forming a Greek cross), as far as possible within the shape of the shield, and they meet in the center (fesse-point) of the shield, except when it is abased (lowered) in the presence of a chief. The plain cross of gules in a field argent is termed Saint George's Cross.
The ordinary formed when the cross' arms are oblique, passing through the top corners of the shield, is referred to as a saltire.
The ordinary cross may further be modify in its flection (i.e. modification of its edges as engrailed (engreslée), embattled (bretessée), indented (denchée), invected (cannelée), wavy, (ondée), raguly (écotée), dancetty or dantelly (denché, émanchée), and so on. French heraldic terminology is even more diverse, with many synonyms leading to some confusion."we are met with the difficulty of many synonyms occurring, for practically the same form is often much varied by incorrect drawing, and much confusion has arisen from blunders of heraldic writers in misreading or misunderstanding the terms employed." Parker (1894).
The ordinary cross may also be varied in its tincture, it may be party, or chequy, compony, counter-compony, fretty, trellised, vair maçonnée and so on. It may also be of two tinctures, e.g. party per fesse, per pale, or per cross (equivalent to quarterly), mostly in connection with the partition of the field (i.e. counter-charged).
The term quarter-pierced (quarterly pierced) is used when the center of the cross has a separate tincture. Some heraldists have used quarter-voided or square-pierced for cases where the center of the cross is given the tincture of the field, or alternatively chequy of nine panes (French ). A cross quadrate has a square at the intersection point.
