During the Middle Age there were many constitutional questions which had not been decided. On many points no theory had been formulated, and the practice varied. Thus it had not been clearly determined how far the pope might control the election of the German king. In 1125 Lothar had asked the pope to confirm his election; Frederick I merely informs the pope of his election and tells him the policy which he intends to pursue. Eugene III "approves" his election, but does not use the more technical word, "confirm." To his most beloved father in Christ, Eugene, pope of the holy Roman church, Frederick, by the grace of God king of the Romans, Augustus, [sends] filial love and reverence. ... Following the custom of the Roman emperors, we have sent to you as ambassadors, Eberhard, venerable bishop of Bamberg, Hillo, bishop elect of Trier, and Adam, abbot of Eberach, to notify you of our election and of the condition of the church and the realm. After the death of Conrad, king of the Romans, all the princes of the kingdom came together at Frankfurt, and on the day of their assembling elected us king. The princes displayed complete harmony in this election and the people received it with the greatest approval and delight. Five days later, just after the middle of Lent, we were anointed at Aachen by your beloved sons, the archbishop of Cologne, and other venerable bishops, and were raised to the throne with their solemn benediction. And now that we have been invested with the royal authority and dignity by the homage of the secular princes and the benediction of the bishops, we intend to assume the royal character, as set forth in our coronation oath; namely, to love and honor the pope, to defend the holy Roman church and all ecclesiastical persons, to maintain peace and order, and to protect the widows and the fatherless and all the people committed to our care. God has established two powers by which this world should be ruled, the papacy and the empire; therefore we are prepared to obey the priests of Christ, in order that, through our zeal, the word of God may prevail during our time, and that no one may disobey with impunity the laws of the holy fathers or the decrees of the councils, and that the church may enjoy her ancient honor and dignity and the empire be restored to its former strength. We know that you were greatly distressed at the death of our uncle and predecessor Conrad, but we assure you, beloved father, that we have succeeded him not only in the kingdom, but also in the love which he bore you. We undertake his work of defending the holy Roman church, and we intend to carry on the plans which he made for the honor and liberty of the apostolic see. Your enemies shall be our enemies, and those that hate you shall suffer our displeasure. 96. Answer of Eugene III, May 17, 1152. Jaffé, I, Wibaldi Epp., no. 382; Doeberl, IV, no. 25 e.
