Conrad IV

His son, Conrad IV., a youth of twenty-one, was scarce to be dreaded in comparison, though Innocent cautiously waited for a while in Lyons before venturing into Italy.

In 1253, when Conrad IV. passed through Treviso to recover possession of his Sicilian kingdom, he appointed as his Lombard vicar-general Uberto Pallavicino, who soon became as obnoxious to the Church as Ezzelin himself; and, though Conrad died in 1254, and Innocent IV. seized Naples as a forfeited fief of the Church, Pallavicino’s power continued to increase, and he soon established relations with Manfred, Frederic’s illegitimate son, who wrested Naples from the papacy and became the chief of the Ghibelline faction.

Still further rewards were offered when personal ambition and vindictiveness were to be gratified in the crusade preached by Innocent IV. against the Emperor Conrad IV., after the death of Frederic II., when he granted a larger remission of sins than for the voyage to the Holy Land, and included the father and mother of the crusader as beneficiaries in the assurance of heaven.

Regained for the Hohenstaufen by Henry’s son, Frederick II., in 1214, the German kingdom passed to his son, Conrad IV., and when Conrad’s son Conradin was beheaded in Italy in 1268, the male line of the Hohenstaufen became extinct.

After a short apostasy, during which he supported Henry Raspe, landgrave of Thuringia, Conrad returned to the side of the Hohenstaufen and aided Conrad IV.
