Hermann III (c.994/995 - April 1, 1012) was a member of the Conradine dynasty. He was Duke of Swabia from 1003 until 1012.
Hermann was the son of Herman II, Duke of Swabia and his wife Gerberga of Burgundy, daughter of Conrad I of Burgundy. [1] He had many illustrious relatives. Through his father, Hermann was descended from Henry the Fowler; through his mother from Louis IV of France, Alfred the Great and Charlemagne. [2] Hermann's sister, Gisela of Swabia, married Emperor Conrad II.
In 1003, when Hermann was about nine years old, his father died and Hermann inherited the duchy of Swabia. Since he was a minor, Hermann's reign as duke was effectively controlled by his cousin, the King of Germany, Henry II, who was his guardian. [3] Henry II was mistrustful of the Conradines. Herman III's father, Herman II, had opposed the election of Henry II as king of Germany in 1002, and promoted himself as a rival candidate for the throne. [4] Henry II thus used his position as Hermann's guardian to limit the power of the dukes of Swabia. He took control of key places in Swabia himself (including Hohentwiel, Breisach and Zürich), and replaced the ducal mint with a royal mint. He separated Alsace from the duchy of Swabia and gave control of Alsace to one of his relatives, Count Gerhard. [5] Henry's control over Swabia was still present when Hermann died, aged about eighteen, in 1012.
Hermann III did not marry and had no heirs. The male line of the Conradines of Swabia came to an end with his death. Henry II selected Ernest to succeed him; two years later, Ernest married Hermann's sister Gisela of Swabia.
The Salian dynasty or Salic dynasty was a dynasty in the High Middle Ages. The dynasty provided four kings of Germany (1024–1125), all of whom went on to be crowned Holy Roman emperors (1027–1125).
Conrad II, also known as Conrad the Elder and Conrad the Salic, was the emperor of the Holy Roman Empire from 1027 until his death in 1039. The first of a succession of four Salian emperors, who reigned for one century until 1125, Conrad ruled the kingdoms of Germany, Italy and Burgundy.
The Dukes of Swabia were the rulers of the Duchy of Swabia during the Middle Ages. Swabia was one of the five stem duchies of the medieval German kingdom, and its dukes were thus among the most powerful magnates of Germany. The most notable family to rule Swabia was the Hohenstaufen family, who held it, with a brief interruption, from 1079 until 1268. For much of that period, the Hohenstaufen were also Holy Roman Emperors. With the death of Conradin, the last Duke of Hohenstaufen, the duchy itself disintegrated although King Rudolf I attempted to revive it for his Habsburg family in the late 13th century.
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.

Gisela of Swabia, was queen of Germany from 1024 to 1039 and empress of the Holy Roman Empire from 1027 to 1039 by her third marriage with Emperor Conrad II. She was the mother of Emperor Henry III. She was regent of Swabia for her minor son Duke Ernest II of Swabia in 1015, although it seems at that time her husband Conrad was the one who held the reins of government, leading to the enmity between stepfather and stepson.
The Conradines or Conradiner were a dynasty of Franconian counts and dukes in the 8th to 11th Century, named after Duke Conrad the Elder and his son King Conrad I of Germany.

A royal election was held in the Kingdom of Germany after the death of childless Emperor Otto III. It was won by Duke Henry IV of Bavaria among accusations of uncustomary practices.
