Yet the emperor seemed so little aware of his son's unpopularity, that he was at this very time making arrangements for securing to him the imperial crown. He had summoned a meeting of the electors and great lords of the empire, to be held at Augsburg, in August, 1550. There he proposed to secure Philip's election as king of the Romans, so soon as he had obtained his brother Ferdinand's surrender of that dignity. But Charles did not show, in all this, his usual knowledge of human nature. The lust of power on his son's account--ineffectual for happiness as he had found the possession of it in his own case--seems to have entirely blinded him. He repaired with Philip to Augsburg, where they were met by Ferdinand and the members of the German diet. But it was in vain that Charles solicited his brother to waive his claim to the imperial succession in favor of his nephew. Neither solicitations nor arguments, backed by the entreaties, even the tears, it is said, of their common sister, the Regent Mary, could move Ferdinand to forego the splendid inheritance. Charles was not more successful when he changed his ground, and urged his brother to acquiesce in Philip's election as his successor in the dignity of king of the Romans; or, at least, in his being associated in that dignity--a thing unprecedented--with his cousin Maximilian, Ferdinand's son, who, it was understood, was destined by the electors to succeed his father. This young prince, who meanwhile had been summoned to Augsburg, was as little disposed as Ferdinand had been to accede to the proposals of his too grasping father-in-law; though he courteously alleged, as the ground of his refusal, that he had no right to interfere with the decision of the electors. He might safely rest his cause on their decision. They had no desire to perpetuate the imperial sceptre in the line of Castilian monarchs. They had suffered enough from the despotic temper of Charles the Fifth; and this temper they had no reason to think would be mitigated in the person of Philip. [Sidenote: AMBITIOUS SCHEMES.] They desired a German to rule over them,--one who would understand the German character, and enter heartily into the feelings of the people. Maximilian's directness of purpose and kindly nature had won largely on the affections of his countrymen, and proved him, in their judgment, worthy of the throne.[40]
