This book analyses the perceptions and functions of heraldry in medieval urban societies by drawing on both English- and German-language sources from the late fourteenth to the early sixteenth centuries. Despite variations that point to socio-political differences between cities (and their citizens) in the relatively centralized monarchy of medieval England and the more independent-minded urban governments found in the less closely connected Holy Roman Empire, urban heraldry emerges as a versatile and ubiquitous means of multimedia visual communication that spanned medieval Europe. These urban heraldic practices defy assumptions about clearly demarcated social practices that belonged to 'high'/'noble' as opposed to 'low'/'urban' culture. Townspeople's perceptions of coats of arms paralleled those of the nobility, as they readily interpreted and carefully curated heraldic signs as visual expressions of identity. These perceptions allowed townspeople of all ranks, as well as noble outsiders, to use heraldry and its display - along with its defacement and destruction - in manuscripts, spaces (such as town houses, public monuments, halls, and churches), and performances (like processions and joyous entries) to address perennial problems of urban society in the Middle Ages. The coats of arms of burgesses, guilds, and cities were communicative means of individual and collective representation, social and political legitimization, conducting and resolving conflicts, and the pursuit of elevated status in the urban hierarchy. Likewise, heraldic communication negotiated the all-important relationship between the city and wider, extramural society - from the commercial interests of citizens to their collective ties to the ruler.
