Heraldry is the system of visual identification of rank and pedigree which developed in the European High Middle Ages,[2] closely associated with the courtly culture of chivalry, Latin Christianity, the Crusades, feudal aristocracy, and monarchy of the time.
[5] Heraldry developed in the high medieval period, based on earlier, "pre-heraldic" or "ante-heraldic", traditions of visual identification by means of seals, field signs, emblems used on coins, etc.
Prior to this, western military shields of the 11th to early 12th century did sometimes show simple decorations, but not apparently tied to the personal identification of the bearer.
[9] Similarly, an account of the French knights at the court of the Byzantine emperor Alexius I at the beginning of the twelfth century describes their shields of polished metal, utterly devoid of heraldic design.
[8][11] The 12th-century tradition is mostly preserved in the form of the equestrian seals popular at the time which show the nobleman as a fully armed warrior on horseback.
The equestrian seal of Enguerrand (Ingelram), count of Saint-Pol (1130s or 1140s) still shows a plain shield, but what would later become heraldic charges (in this case, sheaves of corn) are shown arranged around the horse.
A number of seals dating from between 1135 and 1155 appear to show the adoption of heraldic devices in England, France, Germany, Spain, and Italy.
[15] An equestrian seal of similar antiquity is that of Ottokar III of Styria, dated 1160, with an early form of the Styrian panther on his shield.
Shield designs are described in the Kaiserchronik (c. 1150–1170), such as the boar carried by the Romans, as well as, in isolated cases, in the Rolandslied (c. 1115), König Rother (c. 1150), Veldecke's Eneas (c. 1170), and Hartmann's Erec (c. 1185).
[23] At least two distinctive features of heraldry are generally accepted as products of the Crusades: the surcoat, an outer garment worn over the armor to protect the wearer from the heat of the sun, was often decorated with the same devices that appeared on a knight's shield.
Its slashed or scalloped edge, today rendered as billowing flourishes, is thought to have originated from hard wearing in the field, or as a means of deadening a sword blow and perhaps entangling the attacker's weapon.
[25] The origin of the term heraldry itself (Middle English heraldy, Old French hiraudie), can be placed in the context of the early forms of the knightly tournaments in the 12th century.
"[26] The term coat of arms in origin refers to the surcoat with heraldic designs worn by combatants, especially in the knightly tournament, in Old French cote a armer.
This heater-shaped form was used in warfare during the apogee of the Age of Chivalry, and it becomes the classic heraldic shield, or escutcheon, at about the time of the Battle of Crecy (1346) and the founding of the Order of the Garter (1348), when heraldry had become a fully developed system.
Coats of arms of the 13th century in some cases already include marks of cadency to distinguish descendants, but they mostly still do without division of the field to indicate descent from more than one lineage.
Prominent burghers and corporations, including many cities and towns, assumed or obtained grants of arms, with only nominal military associations.
[36] Heraldic devices were depicted in various contexts, such as religious and funerary art, and in using a wide variety of media, including stonework, carved wood, enamel, stained glass, and embroidery.
[38][39] Since the late nineteenth century, heraldry has focused on the use of varied lines of partition and little-used ordinaries to produce new and unique designs.
National coats of arms are however popular among both constitutional monarchies (like Denmark and Spain) as well as republics (like Finland, Iceland, Portugal, the Gambia, Nigeria, Sierra Leone, Singapore, Chile, Guyana, Trinidad and Tobago, and the United States).
