The Holy Roman Empire, also known as the Holy Roman Empire of the German Nation after 1512, was a polity in Central and Western Europe, usually headed by the Holy Roman Emperor. It developed in the Early Middle Ages and lasted for almost a thousand years until its dissolution in 1806 during the Napoleonic Wars.
A prince-bishop is a bishop who is also the civil ruler of some secular principality and sovereignty, as opposed to Prince of the Church itself, a title associated with cardinals. Since 1951, the sole extant prince-bishop has been the Bishop of Urgell, Catalonia, who has remained ex officio one of two co-princes of Andorra, along with the French president.
In the Holy Roman Empire, the collective term free and imperial cities, briefly worded free imperial city, was used from the 15th century to denote a self-ruling city that had a certain amount of autonomy and was represented in the Imperial Diet.
Fürst is a German word for a ruler as well as a princely title. Fürsten were, starting in the Middle Ages, members of the highest nobility who ruled over states of the Holy Roman Empire and later its former territories, below the ruling Kaiser (emperor) or König (king).
Graf is a historical title of the German nobility and later also of the Russian nobility, usually translated as "count". Considered to be intermediate among noble ranks, the title is often treated as equivalent to the British title of "earl".
An 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 the only authority above them was that of the Holy Roman Emperor. They were thus able to rule their territories with a considerable degree of autonomy.
The mediatised houses were ruling princely and comital-ranked houses that were mediatised in the Holy Roman Empire during the period 1803–1815 as part of German mediatisation, and were later recognised in 1825–1829 by the German ruling houses as possessing considerable rights and rank. With few exceptions, these houses were those whose heads held a seat in the Imperial Diet when mediatised during the establishment of the Confederation of the Rhine in 1806–07, by France in 1810, or by the Congress of Vienna in 1814–15. The mediatised houses were organised into two ranks: the princely houses, entitled to the predicate Durchlaucht, which previously possessed a vote on the Bench of Princes (Furstenbank); and the comital houses that were accorded the address of Erlaucht, which previously possessed a vote in one of the four Benches of Counts (Gräfenbank). Although some form of mediatisation occurred in other countries, such as France, Italy and Russia, only designated houses within the former Holy Roman Empire legally comprised the mediatised houses.
In the Holy Roman Empire, a prince-abbot was the cleric who headed a princely abbey. The prince-abbot had a seat and an individual vote in the Imperial Diet alongside the prince-bishops. They ranked higher than the imperial abbots and imperial abbesses who although they were also immediate, held only two collective votes in the Diet.
German mediatisation was the major redistribution and reshaping of territorial holdings that took place between 1802 and 1814 in Germany by means of the subsumption and secularisation of a large number of Imperial Estates, prefiguring, precipitating, and continuing after the dissolution of the Holy Roman Empire. Most ecclesiastical principalities, free imperial cities, secular principalities, and other minor self-ruling entities of the Holy Roman Empire lost their independent status and were absorbed by the remaining states. By the end of the mediatisation process, the number of German states had been reduced from almost 300 to 39.
The imperial ban was a form of outlawry in the Holy Roman Empire. At different times, it could be declared by the Holy Roman Emperor, by the Imperial Diet, or by courts like the League of the Holy Court (Vehmgericht) or the Reichskammergericht.
Prince of the Holy Roman Empire was a title attributed to a hereditary ruler, nobleman or prelate recognised by the Holy Roman Emperor.
Ellwangen Abbey was the earliest Benedictine monastery established in the Duchy of Swabia, at the present-day town of Ellwangen an der Jagst, Baden-Württemberg, about 100 km (60 mi) north-east of Stuttgart.
Princely abbeys and Imperial abbeys were religious establishments within the Holy Roman Empire which enjoyed the status of imperial immediacy (Reichsunmittelbarkeit) and therefore were answerable directly to the Emperor. The possession of imperial immediacy came with a unique form of territorial authority known as Landeshoheit, which carried with it nearly all the attributes of sovereignty.
The Free Imperial Knights were free nobles of the Holy Roman Empire, whose direct overlord was the Emperor. They were the remnants of the medieval free nobility (edelfrei) and the ministeriales. What distinguished them from other knights, who were vassals of a higher lord, was that they had been granted Imperial immediacy, and as such were the equals in most respects to the other individuals or entities, such as the secular and ecclesiastical territorial rulers of the Empire and the free imperial cities, that also enjoyed Imperial immediacy. However, unlike all of those, the Imperial knights did not possess the status of Estates (Stände) of the Empire, and therefore were not represented, individually or collectively, in the Imperial Diet. They tended to define their responsibilities to the Empire in terms of feudalized obligations to the Emperor, including personal service and strictly voluntary financial offerings paid to the Emperor himself.
The Prince-Bishopric of Bamberg was an ecclesiastical State of the Holy Roman Empire. It goes back to the Roman Catholic Diocese of Bamberg established at the 1007 synod in Frankfurt, at the behest of King Henry II to further expand the spread of Christianity in the Franconian lands. The bishops obtained the status of Imperial immediacy about 1245 and ruled their estates as Prince-bishops until they were subsumed to the Electorate of Bavaria in the course of the German Mediatisation in 1802.
The Princely Abbey of Kempten was an ecclesiastical principality of the Holy Roman Empire for centuries until it was annexed to the Electorate of Bavaria in the course of the German mediatization in 1803.
The Imperial Diet was the deliberative body of the Holy Roman Empire. It was not a legislative body in the contemporary sense; its members envisioned it more like a central forum where it was more important to negotiate than to decide.
Imperial Count was a title in the Holy Roman Empire. During the medieval era, it was used exclusively to designate the holder of an imperial county, that is, a fief held directly (immediately) from the emperor, rather than from a prince who was a vassal of the emperor or of another sovereign, such as a duke or prince-elector. These imperial counts sat on one of the four "benches" of Counts, whereat each exercised a fractional vote in the Imperial Diet until 1806. Imperial counts rank above counts elevated by lesser sovereigns.
