Duke of Swabia

The Ottonian dynasty was a Saxon dynasty of German monarchs (919–1024), named after three of its kings and Holy Roman Emperors named Otto, especially its first Emperor Otto I. 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, after its earliest known member Count Liudolf and one of its most common given names. The Ottonian rulers were successors of the Germanic king Conrad I, who was the only Germanic king to rule in East Francia after the Carolingian dynasty and before this dynasty.

The House of Zähringen was a dynasty of Swabian nobility. The family's name derived from Zähringen Castle near Freiburg im Breisgau. The Zähringer in the 12th century used the title of Duke of Zähringen, in compensation for having conceded the title of Duke of Swabia to the Staufer in 1098. The Zähringer were granted the special title of Rector of Burgundy in 1127, and they continued to use both titles until the extinction of the ducal line in 1218.

Henry II, called the Wrangler or the Quarrelsome, a member of the German royal Ottonian dynasty, was Duke of Bavaria from 955 to 976 and again from 985 to 995, as well as Duke of Carinthia from 989 to 995.

Conrad I, called the Younger, was the king of East Francia from 911 to 918. He was the first king not of the Carolingian dynasty, the first to be elected by the nobility and the first to be anointed. He was chosen as the king by the rulers of the East Frankish stem duchies after the death of young King Louis the Child. Ethnically Frankish, prior to this election he had ruled the Duchy of Franconia from 906.

Frederick I before 21 July was Duke of Swabia from 1079 to his death, the first ruler from the House of Hohenstaufen (Staufer).

Rudolf of Rheinfelden was Duke of Swabia from 1057 to 1079. Initially a follower of his brother-in-law, the Salian emperor Henry IV, his election as German anti-king in 1077 marked the outbreak of the Great Saxon Revolt and the first phase of open conflict in the Investiture Controversy between Emperor and Papacy. After a series of armed conflicts, Rudolf succumbed to his injuries after his forces defeated Henry's in the Battle on the Elster.

Judith of Bavaria, a member of the Luitpolding dynasty, was Duchess consort of Bavaria from 947 to 955, by her marriage with Duke Henry I. After her husband's death, she acted as regent of Bavaria during the minority of her son Henry the Wrangler in 955-972.

Otto I was the Duke of Swabia from 973 and Duke of Bavaria from 976. He was a member of the Ottonian dynasty, the only son of Duke Liudolf of Swabia and his wife Ida, and thus a grandson of the Emperor Otto I and his Anglo-Saxon wife Eadgyth. His sister Mathilde was the abbess of Essen Abbey.

The Duchy of Swabia was one of the five stem duchies of the medieval German Kingdom. It arose in the 10th century in the southwestern area that had been settled by Alemanni tribes in Late Antiquity.

The War of the Three Henries was a brief rebellion of three German princes, all called Henry, against Emperor Otto II in 976–977, with a final peace imposed in 978.

Burchard III, a member of the Hunfriding dynasty, was the count of Thurgau and Zürichgau, perhaps of Rhaetia, and then Duke of Swabia from 954 to his death.

Otto I, traditionally known as Otto the Great, or Otto of Saxony, was East Frankish king from 936 and Holy Roman Emperor from 962 until his death in 973. He was the eldest son of Henry the Fowler and Matilda of Ringelheim.
