On his arrival in Spain Charles sent a courteous letter to Louise of Savoy, who was acting as regent during her son's absence. Louise in reply says: 'Monseigneur! By the letter which it has pleased you to write to me, I have learned the arrival of monseigneur the king, my son, in your country, and the goodwill and good disposition you entertain to treat him well, for which I know not how sufficiently to express to you my thanks and gratitude, humbly beseeching you, sir, to continue to act in this liberal manner, which so well befits your greatness and magnanimity. As for the rest, monseigneur, in pursuance of what you have required of me, I have given a safe conduct to your courier, desiring to do your pleasure in this and all other things, as I would for the said monseigneur, my son, the king, and this the Lord knows, whom I pray to give you a good and long life.--Your most humble LOYSE.'[103] [103] W. Bradford, _Correspondence of the Emperor Charles V._ On June the 25th, 1525, Charles wrote a long letter to his brother Ferdinand from Toledo, in which he says: 'As to the movement of the Lutherans, and the evil they have done, and to all appearance mean to do, it has annoyed, and does continue to annoy me bitterly. If it were in my power to remedy it speedily, I would spare neither my person nor my estates in the cause, but you see the difficulty there is in it, especially since I hope to be in Italy so soon, in order to take possession of my crowns[104] as I have already written you word. [104] The emperor's coronation at Bologna did not take place till February 1530, when he received the crowns of Lombardy and of the empire. 'When that is done, I mean to exert all my power in the extermination of this said sect of Lutherans....' Charles goes on to say, in answer to his brother's request that he would use his influence to get him (Ferdinand) elected King of the Romans, that for the present the matter had better be kept secret until he had been crowned emperor, as the electors 'would probably allege, and with truth, that at present I am myself, in fact, no more than King of the Romans, and that on this account the election of another ought to be deferred.... 'The King of France is now here. I have caused him to be placed in the castle of Patina, where he will be well treated. He has offered me certain articles of peace, which I send you a copy of, and has promised to do still better. I will let you know the result; and if it tends to my honour and advantage, and to the preserving of my friends, I will follow your advice in coming to terms, well knowing that it would be very propitious to my interests to make peace before I leave this for Italy. If the said peace cannot be concluded, I shall order the said King of France to be kept here in all safety, and will deliberate on the subject of a war for next year....
