The Quaternion Eagle (German : Quaternionenadler; Italian : Aquila Quaternione), also known as the Imperial Quaternion Eagle (German : Quaternionen-Reichsadler) [1] [2] or simply Imperial Eagle (German : Reichsadler), [lower-alpha 1] was an informal coat of arms of the Holy Roman Empire.
Introduced around 1510 by Hans Burgkmair, the Quaternion Eagle mixed two pre-existing concepts: the Imperial Quaternions and the Imperial Eagle (double-headed eagle). [lower-alpha 1]
The so-called imperial quaternions (German : Quaternionen der Reichsverfassung, lit. 'quaternions of the imperial constitution'; from Latin : quaterniō , lit. 'group of four soldiers') were a conventional representation of the Imperial States of the Holy Roman Empire which first became current in the 15th century and was extremely popular during the 16th century. [3] [4]
Apart from the highest tiers of the emperor, kings, prince-bishops and the prince electors, the estates are represented in groups of four. The number of quaternions was usually ten, in descending order of precedence:
The list could be shortened or expanded, by the mid-16th century to as many as 45. [5] [6] [7] [8]
It is likely that this system was first introduced under Emperor Sigismund, who is assumed to have commissioned the frescoes in Frankfurt city hall in 1414. [9]
As has been noted from an early time, this representation of the "imperial constitution" does not in fact represent the actual constitution of the Holy Roman Empire, as some imperial cities appear as "villages" or even "peasants" [lower-alpha 2] and the Burggrave of Stromburg [lower-alpha 3] was an unknown entity even at the time. The representation of imperial subjects is also far from complete. The "imperial quaternions" are, rather, a more or less random selection intended to represent pars pro toto the structure of the imperial constitution.
Over its long history, the Holy Roman Empire used many different heraldic forms, representing its numerous internal divisions. One rendition of the coat of the empire was the Quaternion Eagle, printed by David de Negker of Augsburg after a 1510 woodcut by Hans Burgkmair. [2]
Named after the imperial quaternions, it showed a selection of 56 shields of various Imperial States in groups of four on the feathers of a double-headed eagle (the imperial eagle's remiges), supporting, in place of a shield, Christ on the Cross. [10] [2]
The top shields were those of the Prince Electors and the titular Prefect of Rome, being divided into two horizontal quaternions:
Twelve vertical quaternions were shown under them, as follows — eight dukes being divided into two quaternions called "pillars" and "vicars", respectively: [10]

The depiction also appeared on the Imperial Eagle beaker.
An Imperial Eagle beaker (German: Reichsadlerhumpen), or eagle glass, was a popular drinking vessel from the 16th until the late 18th century in the Holy Roman Empire. The enamelled glass was decorated with a double-headed eagle, usually in the shape of a Quaternion Eagle. The Reichsadler means "Imperial Eagle" or double-headed eagle which was the emblem of the empire, while "humpen" refers to a cylindrical drinking glass. [11] [12] These beakers became the essential medium to represent the most popular explanatory model for the emergence of the Empire: the quaternion theory as represented by Hans Burgkmair.
The Imperial Eagle beakers showed the solidarity between the owner and the Empire and were very popular because of their decorativeness and luminous colors. But these drinking vessels were also valued for their generous size. Equally popular were the electors' beakers, which were decorated with illustrations of the emperor and electors as the most important representatives of the Empire.
Many good examples of Imperial Eagle beakers are on display in museums worldwide. At auctions well-preserved pieces achieve a selling price of up to several thousand euros.The prince-electors, pl. Kurfürsten, Czech: Kurfiřt, Latin: Princeps Elector) were the members of the electoral college that elected the ruler of the Holy Roman Empire.
The Holy Roman Emperor, originally and officially the Emperor of the Romans during the Middle Ages, and also known as the Roman-German Emperor since the early modern period, was the ruler and head of state of the Holy Roman Empire. The title was held in conjunction with the title of king of Italy from the 8th to the 16th century, and, almost without interruption, with the title of king of Germany throughout the 12th to 18th centuries.
Charles VII was Prince-Elector of Bavaria from 26 February 1726 and Holy Roman Emperor from 24 January 1742 to his death. He was also King of Bohemia from 1741 to 1743. Charles was a member of the House of Wittelsbach, and his reign as Holy Roman Emperor thus marked the end of three centuries of uninterrupted Habsburg imperial rule, although he was related to the Habsburgs by both blood and marriage.
Imperial Reform is the name given to repeated attempts in the 15th and 16th centuries to adapt the structure and the constitutional order of the Holy Roman Empire to the requirements of the early modern state and to give it a unified government under either the Imperial Estates or the emperor's supremacy.
The coat of arms of Germany displays a black eagle with a red beak, a red tongue and red feet on a golden field, which is blazoned: Or, an eagle displayed sable beaked langued and membered gules. This is the Bundesadler, formerly known as Reichsadler. It is one of the oldest coats of arms in the world, and today the oldest national symbol used in Europe.
An Imperial State or Imperial Estate was a part of the Holy Roman Empire with representation and the right to vote in the Imperial Diet. Rulers of these Estates were able to exercise significant rights and privileges and were "immediate", meaning that the only authority above them was the Holy Roman Emperor. They were thus able to rule their territories with a considerable degree of autonomy.
King in Prussia was a title used by the Prussian kings from 1701 to 1772. Subsequently, they used the title King of Prussia.
Hans Burgkmair the Elder (1473–1531) was a German painter and woodcut printmaker.
Imperial Count Heinrich von Bünau was a politician and historian from the Electorate of Saxony, now part of Germany.
An imperial vicar was a prince charged with administering all or part of the Holy Roman Empire on behalf of the emperor. Later, an imperial vicar was invariably one of two princes charged by the Golden Bull with administering the Holy Roman Empire during an interregnum.
The Reichsadler is the heraldic eagle, derived from the Roman eagle standard, used by the Holy Roman Emperors and in modern coats of arms of Germany, including those of the Second German Empire (1871–1918), the Weimar Republic (1919–1933) and Nazi Germany (1933–1945).

Johann Georg Estor, was a German theorist of public law, historian and book collector.
The Frankfurt Constitution or Constitution of St. Paul's Church (Paulskirchenverfassung), officially named the Constitution of the German Empire of 28 March 1849, was an unsuccessful attempt to create a unified German nation state in the successor states of the Holy Roman Empire organised in the German Confederation. Adopted and proclaimed by the Frankfurt Parliament after the Revolutions of 1848, the constitution contained a charter of fundamental rights and a democratic government in the form of a constitutional monarchy. King Frederick William IV of Prussia was designated head of state as "Emperor of the Germans", a role he rejected.

The chancellor of Germany, officially the federal chancellor of the Federal Republic of Germany, is the head of the federal government of Germany, and the commander-in-chief of the German Armed Forces during wartime. The chancellor is the chief executive of the Federal Cabinet and heads the executive branch. The chancellor is elected by the Bundestag on the proposal of the federal president and without debate.
German heraldry is the tradition and style of heraldic achievements in Germany and the Holy Roman Empire, including national and civic arms, noble and burgher arms, ecclesiastical heraldry, heraldic displays and heraldic descriptions. German heraldic style is one of the four major broad traditions within European heraldry and stands in contrast to Gallo-British, Latin and Eastern heraldry, and strongly influenced the styles and customs of heraldry in the Nordic countries, which developed comparatively late. Together, German and Nordic heraldry are often referred to as German-Nordic heraldry.
The Treaty of Grimnitz was the final settlement of a long-standing dispute between the House of Pomerania and the House of Hohenzollern regarding the legal status and succession in the Duchy of Pomerania. It renewed and amended the Treaty of Pyritz of 1493.
A Reichskrieg was a war fought by the Holy Roman Empire as a whole against a common enemy. After the Peace of Westphalia in 1648, a Reichskrieg was a formal state of war that could only be declared by the Imperial Diet.
