Stem duchy in the context of "Bavaria"

An Imperial Estate (Latin: Status Imperii; German: Reichsstand, plural: Reichsstände) was an entity or an individual of the Holy Roman Empire with representation and the right to vote in the Imperial Diet (Reichstag). 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 system of imperial states replaced the more regular division of Germany into stem duchies in the early medieval period. The old Carolingian stem duchies were retained as the major divisions of Germany under the Salian dynasty, but they became increasingly obsolete during the early high medieval period under the Hohenstaufen, and they were finally abolished in 1180 by Frederick Barbarossa in favour of more numerous territorial divisions. From 1489, the Imperial Estates represented in the Diet were divided into three chambers, the college of prince-electors (Kurfürstenkollegium/den Kurfürstenrat), the college of imperial princes (Reichsfürstenrat) and the college of imperial cities. Counts and nobles were not directly represented in the Diet in spite of their immediate status, but were grouped into "benches" (Grafenbänke) with a single vote each.Imperial Knights and imperial villages had immediate status but were not represented in the Diet.

The Saxons, sometimes called the Old Saxons or Continental Saxons, were a Germanic people of early medieval "Old" Saxony (Latin: Antiqua Saxonia) which became a Carolingian "stem duchy" in 804, in what is now northern Germany, between the lower Rhine and Elbe rivers. Many of their neighbours were, like them, speakers of West Germanic dialects, including both the Franks and Thuringians to the south, and the coastal Frisians and Angles to the north who were among the peoples who were originally referred to as "Saxons" in the context of early raiding and settlements in Roman Britain and Gaul. To their east were Obotrites and other Slavic-speaking peoples.

The political history of these continental Saxons is unclear until the 8th century and the conflict between their semi-legendary hero Widukind and the Frankish emperor Charlemagne. They do not appear to have been politically united until the generations of conflict leading up to that defeat, before which they were reportedly ruled by regional "satraps". Previous Frankish rulers of Austrasia, both Merovingian and Carolingian, fought numerous campaigns against Saxons, both in the west near the Lippe, Ems and Weser, and further east, near Thuringia and Bohemia, including the area which later medieval sources referred to as "North Swabia". Charlemagne conquered all the Saxons after winning the long Saxon Wars (772–804 AD) and forced them to convert to Christianity, annexing Saxony into the Carolingian domain. Under the Carolingian Franks, Saxony became a single duchy, fitting it within the basic political structure of the later Holy Roman Empire. The early rulers of this Duchy of Saxony expanded their territories—and therefore those of the Holy Roman Empire—to the east, at the expense of Slavic-speaking Wends.

The title Duke (and Prince) of the Franks (Latin: dux (et princeps) Francorum) has been used for three different offices, always with "duke" implying military command and "prince" implying something approaching sovereign or regalian rights. The term "Franks" may refer to an ethnic group or to the inhabitants of a territory called Francia.

The first office was that of the mayors of the palace of the Merovingian kings of the Franks, whose powers increased as those of the kings declined. The second was that of the second-in-command to the early kings of France, the last incumbent of which succeeded to the throne in 987. This title was sometimes rendered as Duke of France (dux Franciae). The third instance was that of the rulers in East Francia (now Germany) of the so-called "tribal" duchy of Franconia.

Southern Germany (German: Süddeutschland, [ˈzyːtˌdɔʏtʃlant] ) is a region of Germany that includes the areas in which Upper German dialects are spoken, which includes the stem duchies of Bavaria and Swabia in present-day Bavaria, Baden-Württemberg, and the southern portion of Hesse and Rhineland-Palatinate that were part of the Duchy of Franconia.

German-speaking Switzerland, Austria, Liechtenstein, Alsace, and South Tyrol are also historically, culturally, and linguistically associated with the region.

The Ottonian dynasty (German: Ottonen) was a Saxon dynasty of German monarchs (919–1024), named after three of its kings and Holy Roman emperors, especially Otto the Great. It is also known as the Saxon dynasty after the family's origin in the German stem duchy of Saxony. The family itself is also sometimes known as the Liudolfings (Liudolfinger), after its earliest known member Count Liudolf (d. 866) and one of its most common given names. The Ottonian rulers were successors of Conrad I, who was the only German king to rule in East Francia after the Carolingian dynasty.

The Ottonians are associated with the notable military success that transformed the political situation in contemporary Western Europe: "It was the success of the Ottonians in molding the raw materials bequeathed to them into a formidable military machine that made possible the establishment of Germany as the preeminent kingdom in Europe from the tenth through the mid-thirteenth century." They are also associated with a notable cultural movement (especially new literary traditions) known as the Ottonian Renaissance.
