About seven miles to the north-east of Stuttgart, in what is now the kingdom of Wurtemberg, is a small town called Waiblingen, where was once a stronghold, near the borders of Franconia and Suabia (or Alemannia), belonging to the Franconian dukes. Conrad, often called “the Salic,” head of that house, was raised to the throne of Germany and the Empire in 1024. His line held the imperial crown for just a century, in the persons of himself and three Henries, who are known as the second, third, and fourth, or third, fourth, and fifth, according as we reckon their places among Roman Emperors or German Kings; Henry III. (or IV.) being famous as the great opponent of Pope Gregory VII.; Henry IV. (or V.) interesting to us as the first husband of the daughter of Henry I. of England, renowned in English history as the Empress Maud. The last Henry died childless in 1125. But the Franconian line was not extinct. Half a century or so before, Bishop Otto of Freising tells us “a certain count, by name Frederick, sprung from one of the noblest families of Suabia, had founded a colony in a stronghold called Staufen.” Staufen, better known as Hohenstaufen, is a lofty hill about twenty miles from Waiblingen, and within the Suabian frontier. Frederick had been staunch to Henry IV. in his time of greatest difficulty, and received as his reward, together with the dukedom of Suabia, which the house of Zähringen had forfeited through disloyalty, the hand of the Emperor’s daughter Agnes. By her he had two sons, Frederick, who succeeded to his own duchy of Suabia, and Conrad, who received from his uncle Henry V. that of Franconia, including no doubt the lordship of Waiblingen. At Henry’s death Frederick and Conrad, being then thirty-five and thirty-three years old respectively, were the most powerful princes of the Empire. Henry had designated Frederick as his successor; but the electors thought otherwise. At the instance of the Archbishop of Mainz, between whom and the Hohenstaufen there was no love lost, and, as it would seem, not without pressure from Lewis VI. of France, whom Henry’s death had just saved from having to face an alliance between England and Germany, they chose Lothar, Duke of Saxony.
