Because Roger of Sicily had supported the antipope, Bernard had urged Lothar to make war on him. [See no. 91.] But Innocent had, in the meantime, without consulting the emperor, made a treaty with Roger and won his support by also granting him the royal title (1139). Conrad III was offended by this and protested against it. Conrad declared that the kingdom which Roger held, that is, Sicily and southern Italy, was a part of the empire, and therefore the pope had no right to recognize Roger as king there. Conrad regarded Roger as a usurper. He wrote a letter to Bernard complaining of the action of the pope. But Bernard had changed his sentiments since Roger had espoused the cause of Innocent and had received papal confirmation. In a somewhat curt manner he tells Conrad to obey the pope. I, unworthy person that I am, have received your letter and greeting with gratitude and devotion. The complaints of the king are ours also, especially in regard to the usurpation of the Sicilian. I have never desired the disgrace of the king nor the diminution of his realm; my soul hates such as do desire these things. But I read: "Let every soul be subject unto the higher powers; whosoever resisteth the power, resisteth the ordinance of God" [Rom. 13:1, 2]. Hearken to this admonition, I pray you, and show such reverence to St. Peter and to his vicar as you wish to be shown to you by the whole empire. There are certain other matters which I have thought better not to put in writing; perhaps it would be better to speak of them to you personally when I see you. 93. Letter of Conrad III to the Greek Emperor, John Comnenus, 1142. Otto Fris. Gesta Frid., I, c. 25; M. G. SS. folio, XX; Doeberl, IV, no. 12. Although the German and Greek emperors had not adjusted their conflicting claims to southern Italy and Sicily (see no. 58, introductory note), they were agreed in regarding the Normans as usurpers and a common enemy. In order to destroy them the emperors determined to make common cause against them, as is apparent from the following letter. John Comnenus, wishing to strengthen the alliance with Conrad, asked him to choose some German princess for his son, Manuel. Conrad chose his sister-in-law, Bertha von Sulzbach, who, at the time of her marriage with Manuel, assumed the name Irene. Conrad, by the grace of God emperor of the Romans, Augustus, to John, by the same grace emperor of Constantinople, greeting and fraternal love.
