Traditions
American Tradition
As the use of coats of arms may be seen as a custom of royalty and nobility, it had been debated whether the use of arms is reconcilable with American republican traditions. Families from English, Scottish, Irish, Welsh, German, and other European nations with a heraldic tradition have retained their familial coat of arms in the United States. Several founding fathers also employed personal arms and a great number of Americans continue to do so.
Canadian Tradition
Derived mainly from heraldic traditions in France and the United Kingdom, Canadian heraldry also incorporates distinctly Canadian symbols, especially native flora and fauna, references to the First Nations, Inuit and other aboriginal peoples of Canada, and uniquely Canadian elements such as the Canadian pale, derived from the Canadian flag. A unique system of cadency is used for daughters inheriting arms, and a special symbol for United Empire Loyalists.
Iberian Tradition
The most common shape of heraldic shield used in Spain and Portugal is the Iberian style (also referred as "Peninsular", "Spanish" or "Portuguese") which has a simple shape, square on top and round at the bottom. The charges shown on Iberian armorial bearings can depict historical events or deeds of war. They are also characterized by a widespread use of orles and borders around the edge of the shield. In addition to borders, Spain and Portugal marshal arms more conventionally by quartering. The Iberian heraldry also allows words and letters on the shield itself, a practice which is considered incorrect in northern Europe. Crests and helmets are also common in Spain and Portugal.
