context_page_description: A prince-bishop is a bishop who is also the civil ruler of some secular principality and sovereignty. Thus the principality or prince-bishopric ruled politically by a prince-bishop could wholly or largely overlap with his diocesan jurisdiction, since some parts of his diocese, even the city of his residence, could be exempt from his civil rule, obtaining the status of free imperial city. If the episcopal see is an archbishop, the correct term is prince-archbishop; the equivalent in the regular clergy is prince-abbot. A prince-bishop is usually considered an elected monarch.
  In the West, with the decline of imperial power from the 4th century onwards in the face of the barbarian invasions, sometimes Christian bishops of cities took the place of the Roman commander, made secular decisions for the city and led their own troops when necessary. Later relations between a prince-bishop and the burghers were invariably not cordial. As cities demanded charters from emperors, kings, or their prince-bishops and declared themselves independent of the secular territorial magnates, friction intensified between burghers and bishops.
context_section_description: Bishops had been involved in the government of the Frankish realm and subsequent Carolingian Empire frequently as the clerical member of a duo of envoys styled Missus dominicus, but that was an individual mandate, not attached to the see. Prince-bishoprics were most common in the feudally fragmented Holy Roman Empire, where many were formally awarded the rank of an Imperial Prince Reichsfürst, granting them the immediate power over a certain territory and a representation in the Imperial Diet (Reichstag).
  The stem duchies of the German kingdom inside the Empire had strong and powerful dukes (originally, war-rulers), always looking out more for their duchy's "national interest" than for the Empire's. In turn the first Ottonian (Saxon) king Henry the Fowler and more so his son, Emperor Otto I, intended to weaken the power of the dukes by granting loyal bishops Imperial lands and vest them with regalia privileges. Unlike dukes they could not pass hereditary titles and lands to any descendants. Instead the Emperors reserved the implementation of the bishops of their proprietary church for themselves, defying the fact that according to canon law they were part of the transnational Catholic Church. This met with increasing opposition by the Popes, culminating in the fierce Investiture Controversy of 1076. Nevertheless, the Emperors continued to grant major territories to the most important (arch)bishops. The immediate territory attached to the episcopal see then became a prince-diocese or bishopric (Fürstbistum). The German term Hochstift was often used to denote the form of secular authority held by bishops ruling a prince-bishopric with Erzstift being used for prince-archbishoprics.
  Emperor Charles IV by the Golden Bull of 1356 confirmed the privileged status of the Prince-Archbishoprics of Mainz, Cologne and Trier as members of the electoral college. At the eve of the Protestant Reformation, the Imperial states comprised 53 ecclesiastical principalities. They were finally secularized in the 1803 German Mediatization upon the territorial losses to France in the Treaty of Lunéville, except for the Mainz prince-archbishop and German archchancellor Karl Theodor Anton Maria von Dalberg, who continued to rule as Prince of Aschaffenburg and Regensburg. With the dissolution of the Holy Roman Empire in 1806, the title finally became defunct. However, in some countries outside of French control, such as in the Austrian Empire (Salzburg, Seckau, and Olomouc) and the Kingdom of Prussia (Breslau), the institution nominally continued, and in some cases was revived; a new, titular type arose.
  No less than three of the (originally only seven) prince-electors, the highest order of Reichsfürsten (comparable in rank with the French pairs), were prince-archbishops, each holding the title of Archchancellor (the only arch-office amongst them) for a part of the Empire; given the higher importance of an electorate, their principalities were known as Kurfürstentum ("electoral principality") rather than prince-archbishoprics:
  The suffragan-bishoprics of Gurk (established 1070), Chiemsee (1216), Seckau (1218), and Lavant (1225) sometimes used the Fürstbischof title, but never held any reichsfrei territory. The bishops of Vienna (established 1469) and Wiener Neustadt (1469–1785) didn't control any territory, nor did they claim a princely title.
