The Holy Roman Empire was a political entity in Western, Central, and Southern Europe that developed in the Early Middle Ages and continued until its dissolution in 1806 during the Napoleonic Wars.
In the Holy Roman Empire, the collective term free and imperial cities, briefly worded free imperial city, was used from the fifteenth century to denote a self-ruling city that had a certain amount of autonomy and was represented in the Imperial Diet. An imperial city held the status of Imperial immediacy, and as such, was subordinate only to the Holy Roman Emperor, as opposed to a territorial city or town which was subordinate to a territorial prince – be it an ecclesiastical lord or a secular prince.
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, usually translated as "count". Considered to be intermediate among noble ranks, the title is often treated as equivalent to the British title of "earl".
Bremen-Verden, formally the Duchies of Bremen and Verden, were two territories and immediate fiefs of the Holy Roman Empire, which emerged and gained imperial immediacy in 1180. By their original constitution they were prince-bishoprics of the Archdiocese of Bremen and Bishopric of Verden.
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.
A prince-abbot is a title for a cleric who is a Prince of the Church, in the sense of an ex officio temporal lord of a feudal entity, usually a State of the Holy Roman Empire. The territory ruled by a prince-abbey is known as a princely abbey, a prince-abbacy or an abbey principality. The holder, however, does not hold the ecclesiastical office of a bishop.
German mediatisation was the major territorial restructuring that took place between 1802 and 1814 in Germany and the surrounding region by means of the mass mediatisation and secularisation of a large number of Imperial Estates. 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 into the remaining states. By the end of the mediatisation process, the number of German states had been reduced from almost 300 to just 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 as such 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 the fact 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.
Herzog is a German hereditary title held by one who rules a territorial duchy, exercises feudal authority over an estate called a duchy, or possesses a right by law or tradition to be referred to by the ducal title. The word is usually translated by the English duke and the Latin dux. Generally, a Herzog ranks below a king and above a count. Whether the title is deemed higher or lower than titles translated into English as "prince" (Fürst) has depended upon the language, country and era in which the titles coexisted.
In the Holy Roman Empire, the German term (das) Hochstift referred to the territory ruled by a bishop as a prince, as opposed to his diocese, generally much larger and over which he exercised only spiritual authority. The terms prince-bishopric and ecclesiastical principality are synonymous with Hochstift. Erzstift and Kurerzstift referred respectively to the territory (prince-archbishopric) ruled by a prince-archbishop and an elector-archbishop while Stift referred to the territory ruled by an imperial abbot or abbess, or a princely abbot or abbess. Stift was also often used to refer to any type of ecclesiastical principality.
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. In 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.
The dissolution of the Holy Roman Empire occurred de facto on 6 August 1806, when the last Holy Roman Emperor, Francis II of the House of Habsburg-Lorraine, abdicated his title and released all imperial states and officials from their oaths and obligations to the empire. Since the Middle Ages, the Holy Roman Empire had been recognized by Western Europeans as the legitimate continuation of the ancient Roman Empire due to its emperors having been proclaimed as Roman emperors by the papacy. Through this Roman legacy, the Holy Roman Emperors claimed to be universal monarchs whose jurisdiction extended beyond their empire's formal borders to all of Christian Europe and beyond. The decline of the Holy Roman Empire was a long and drawn-out process lasting centuries. The formation of the first modern sovereign territorial states in the 16th and 17th centuries, which brought with it the idea that jurisdiction corresponded to actual territory governed, threatened the universal nature of the Holy Roman Empire.
