Summary
On the 4th of March, 1152, Frederick Barbarossa, nephew of the late king and son of Frederick Duke of Suabia, was elected Emperor at the Diet of Frankfurt, and crowned in the same month at Aix-la-Chapelle. Allied through his mother to the Guelfs of Bavaria, and anxious to put an end to the enmity which existed between the families of Guelf and Hohenstaufen, he began his reign by promising to secure the Duchy of Bavaria for Henry the Lion, and by investing Henry's uncle, Count Guelf, with the Marquisate of Tuscany and the Duchy of Spoleto. Envoys were sent to Pope Eugenius III and to all Italy announcing his election, and, six months later, at the Diet of Wiirzburg, Robert of Capua, and other seigniors of Apulia, who had been despoiled of their territories by Roger of Sicily, presented themselves before the Emperor, beseeching justice and aid. Frederick promised to reinstate them, and ordered all the feudatories of the German kingdom to make ready to follow him to Italy, within two years at the furthest. In the autumn of 1154 he appeared on the plains of Roncaglia on the Po at the head of a great army.
It was a very ancient feudal custom that the kings of Italy should summon all the vassals of the kingdom to a parlamentum at Roncaglia.
