Before the name of your tailor, the make and model of your car, or the size of your superyacht mattered, and before logo-laden handbags or even old school ties, the status symbol for the seriously superior European was the coat of arms. Nobility of birth is no longer required. Nobility of spirit is more important.
In the later Middle Ages, heraldic symbols identified knights in battle, their property, and the members of their private armies, eventually becoming part of a pan-European system of courtly ceremony. In the 15th century, Richard III incorporated the English heralds, who organised such matters, and installed them in the College of Arms. They ensured that heraldic symbols were unique, officially approved and registered, designed according to specific rules, and were only displayed by those properly entitled to them.
