heraldry for a fuller account of the history, design, and regulation of coats of arms.''
A 'coat of arms' or 'armorial bearings' (often just 'arms' for short), in
European tradition, is a design belonging to a particular person (or group of people) and used by them in a wide variety of ways. Unlike
seals and
emblems, coats of arms have a formal description that is expressed as a
blazon.
Traditions and usage

The German Hyghalmen Roll, ca. late 15th century, illustrates the German practice of thematic repetition from the arms in the crest
In some heraldic traditions (i.e. Scottish, English), an individual (rather than a family) has a coat of arms. In those traditions, coats of arms are legal property transmitted from father to son, and are used only by a given person at any one time (other than the man's eldest son and his eldest son, both of whom would differentiate themselves with a label). Other children in these families would only use a form of their father's arms that are
differenced with a color change or the addition of a distinguishing
charge, once specifically approved.
Because of their importance as legal property, the use of arms as a distinguishing mark has necessitated their strict regulation (few countries continue in this today); this has been carried out by
heralds and the study of coats of arms is called "heraldry." In Scotland, the
Lord Lyon has criminal jurisdiction to enforce the laws of arms. In England, the use of arms is a matter of civil law. Some traditions (e.g. Polish) are less restrictive — allowing, for example, all members of a dynastic house or family to use the same arms, although one or more elements may be reserved to the Head of the House.
Today, the term "coat of arms" or "arms" is frequently applied in two different ways. In some uses, it may indicate a 'full achievement of arms' or 'heraldic achievement', which includes a variety of elements — usually a
crest sitting atop a
helmet, itself sitting on a
shield; other common elements include
supporters holding up the shield and a
motto (beneath in England, above in Scotland). Some people wrongly use "coat of arms" or "arms" to refer to the '
escutcheon' (i.e. the shield itself), or to one of several designs that may be combined in one shield. (Note that the crest is one specific part of a heraldic achievement and that "crest of arms" is a misnomer.) The "coat of arms" frequently are adorned with a device - a
motto,
emblem, or other mark used by a
Knight-errant to distinguish himself from others. If a motto is a part of the achievement, it sometimes has some punning allusion to his name. A device differed from a
badge or
cognizance primarily because it is a personal distinction, and not a badge borne by members of the same house successively.
The Japanese equivalents, called ''
kamon'' (often abbreviated "mon"), are family badges which often date back to the seventh century, and are still actively used in Japan today.

In the
Nordic countries, provinces, regions, cities and municipalities have a coat of arms. These are posted to the borders and shown in official documents advertising the area.
At a national level, "coats of arms" were generally retained by those states with constitutional continuity of more than a few centuries, including constitutional monarchies like
Denmark as well as old republics like
San Marino and
Switzerland. However, today, nearly every nation in every part of the world has its own "coat of arms", in many cases emblems that do not fully conform with European heraldric traditions. Since 1989, some of the ex-Communist states, such as
Romania, have resumed their former arms, often with only the symbols of monarchy removed.
The
Great Seal of the United States is often said to be the coat of arms of the
United States of America. Although the seal contains some armorial elements, it was not designed to be used as a coat of arms and does not fully conform with
European heraldic traditions. However, the main point of contention in this dispute is a matter of wording; the blazon is intentionally improper to preserve the number 13 in the symbolism. Nevertheless, the design of the Great Seal of the United States owes more to Roman civil government seals than to medieval European heraldry. The U.S. state of
Vermont, founded as the
Vermont Republic, follows the American convention of assigning use of a seal for authenticating official state documents, but also has the
coat of arms of Vermont. It is the only U.S. state to have authentic armorial bearings described in a
blazon.
Flags and banners
Note that not all personal or corporate insignia are heraldic, though they may share many features. For example,
flags are used to identify ships (where they are called
ensigns), embassies and such, and they use the same colors and designs found in heraldry, but they are not usually considered to be heraldic. A country may have both a national flag and a national coat of arms, and the two may not look alike at all. For example, the
flag of Scotland (St Andrew's Cross) has a white
saltire on a blue
field, but the
royal arms of Scotland has a red lion within a double tressure on a gold field.
