Coats of arms of the Holy Roman Empire (Principia Moderni III Map Game)

Over its long history, the Holy Roman Empire has used many different heraldic forms, representing its numerous internal divisions.

Holy Roman Emperors
Starting with Albert II (reigned 1410 - present), each Emperor bore arms with an inescutcheon of his personal arms on the torso of a two-headed eagle. (Before 1410 the Emperors would have both a personal and an imperial coat of arms.) The arms of the High Offices of the Empire were borne as an augmentation to the office-holder's personal arms.
