Duchy of Swabia in the context of "Alamannia"

The Hohenstaufen dynasty (/ˈhoʊənʃtaʊfən/, US also /-staʊ-/, German: [ˌhoːənˈʃtaʊfn̩]), also known as the Staufer, was a noble family of German origin that rose to rule the Duchy of Swabia from 1079, and to royal rule in the Holy Roman Empire during the Middle Ages from 1138 until 1254. The dynasty's most prominent rulers – Frederick I (1155), Henry VI (1191) and Frederick II (1220) – ascended the imperial throne and also reigned over Italy and Burgundy. The non-contemporary name of 'Hohenstaufen' is derived from the family's Hohenstaufen Castle on Hohenstaufen mountain at the northern fringes of the Swabian Jura, near the town of Göppingen. Under Hohenstaufen rule, the Holy Roman Empire reached its greatest territorial extent from 1155 to 1268.

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.

A stem duchy (German: Stammesherzogtum, from Stamm, meaning "tribe", in reference to the Franks, Saxons, Bavarians and Swabians) was a constituent duchy of the Kingdom of Germany at the time of the extinction of the Carolingian dynasty (death of Louis the Child in 911) and through the transitional period leading to the formation of the Ottonian dynasty. The Carolingians had dissolved the original tribal duchies of the Empire in the 8th century. As the Carolingian Empire declined, the old tribal areas assumed new identities. The five stem duchies (sometimes also called "younger stem duchies" in contrast to the pre-Carolingian tribal duchies) wereBavaria, Franconia, Lotharingia (Lorraine), Saxony and Swabia (Alemannia). The Salian emperors (reigned 1027–1125) retained the stem duchies as the major divisions of Germany, but the stem duchies became increasingly obsolete during the early high-medieval period under the Hohenstaufen, and Frederick Barbarossa finally abolished them in 1180 in favour of more numerous territorial duchies.

The term Stammesherzogtum as used in German historiography dates to the mid-19th century, and from the beginning was closely related to the question of national unification. The term's applicability, and the nature of the stem duchies in medieval Germany, consequently have a long history of controversy.The overly literal or etymologizing English translation "stem duchy" was coined in the early 20th century. While later authors tend to clarify the term by using the alternative translation "tribal", use of the term "stem duchies" has become conventional.

The Margraviate of Baden (German: Markgrafschaft Baden) was a historical territory of the Holy Roman Empire. Spread along the right banks of the Upper Rhine in south-western Germany, it was named a margraviate in 1112 and existed until 1535, when it was split into the two margraviates of Baden-Durlach and Baden-Baden. The two parts were reunited in 1771 under Margrave Charles Frederick, even if the three parts of the state maintained their distinct seats to the Reichstag. The restored Margraviate of Baden was elevated to the status of electorate in 1803. In 1806, the Electorate of Baden, receiving territorial additions, became the Grand Duchy of Baden. The rulers of Baden, known as the House of Baden, were a line of the Swabian House of Zähringen.

Swabia is a cultural, historic and linguistic region in southwestern Germany. The name is ultimately derived from the medieval Duchy of Swabia, one of the German stem duchies, representing the historic settlement area of the Germanic tribe alliances named Alemanni and Suebi.

This territory would include all of the Alemannic German area, but the modern concept of Swabia is more restricted, due to the collapse of the duchy of Swabia in the thirteenth century. Swabia as understood in modern ethnography roughly coincides with the Swabian Circle of the Holy Roman Empire as it stood during the early modern period, now divided between the states of Bavaria and Baden-Württemberg.

Habsburg Castle (German: Schloss Habsburg, lit. 'Castle of the Hawk's hill', pronounced [ˌʃlɔs ˈhaːpsbʊʁk] ) is a medieval Swiss fortress located in what is now Habsburg, Switzerland, in the canton of Aargau, near the Aar River. At the time of its construction, the location was part of the Duchy of Swabia. Habsburg Castle is the original seat of the House of Habsburg, which became one of the leading imperial and royal dynasties in Europe. It is listed as a Swiss heritage site of national significance.

Henry III (German: Heinrich III, 28 October 1016 – 5 October 1056), called the Black (German: Heinrich der Schwarze) or the Pious, was Holy Roman Emperor from 1046 until his death in 1056. A member of the Salian dynasty, he was the eldest son of Conrad II and Gisela of Swabia.

Henry was raised by his father, who made him Duke of Bavaria in 1026, appointed him co-ruler in 1028 and bestowed him with the duchy of Swabia and the Kingdom of Burgundy ten years later in 1038. The emperor's death the following year ended a remarkably smooth and harmonious transition process towards Henry's sovereign rule, that was rather uncharacteristic for the Ottonian and Salian monarchs. Henry succeeded Conrad II as Duke of Carinthia and King of Italy and continued to pursue his father's political course on the basis of virtus et probitas (courage and honesty), which led to an unprecedented sacral exaltation of the kingship. In 1046 Henry ended the papal schism, was crowned Emperor by Pope Clement II, freed the Vatican from dependence on the Roman nobility and laid the foundation for its empire-wide authority. In the duchies, Henry enforced the sovereign royal right of disposition, thereby ensuring tighter control. In Lorraine, this led to years of conflict from which he emerged victorious. Another sphere of defiance formed in southern Germany from 1052 to 1055. Henry III died in 1056, aged only 39. Modern historians identify the final years of his reign as the beginning of a crisis in the Salian monarchy.
