Grand Burgher [male] or Grand Burgheress [female] (from German: Großbürger [male], Großbürgerin [female]) is a specific conferred or inherited title of medieval German origin and legally defined preeminent status granting exclusive constitutional privileges and legal rights (German: Großbürgerrecht), who were magnates and subordinate only to the Emperor, independent of feudalism and territorial nobility or lords paramount. A member class within the patrician ruling elite, the Grand Burgher was a type of urban citizen and social order of highest rank, a formally defined upper social class of affluent individuals and elite burgher families in medieval German-speaking city-states and towns under the Holy Roman Empire, who usually were of a wealthy business or significant mercantile background and estate. This hereditary title and influential constitutional status, privy to very few individuals and families across Central Europe, formally existed well into the late 19th century and early part of the 20th century. In autonomous German-speaking cities and towns of Central Europe that held a municipal charter, town privileges (German town law) or were a free imperial city such as Hamburg, Augsburg, Cologne and Bern that held imperial immediacy, where nobility had no power of authority or supremacy, the Grand Burghers (Großbürger) or patricians ("Patrizier") constituted the ruling class.
