Arms
The custom of completely encasing knights in a suit of armour, thus rendering them indistinguishable, led to the practice of painting their insignia on their shield as a means of identification. The insignia were also embroidered on the knights surcoat or tabard and were called coats of arms. This term was retained even when displayed other than on the surcoat. Originally granted only to individuals, these insignia were afterward made hereditary by King Richard I during his crusade to the Holy Land. There are two classes of arms:
Public: kingdoms, provinces, bishoprics, corporate bodies, etc.
Private: private families.
Depending on the various methods for the grant of arms, these two classes are further subdivided as follows:
