Before his accession to the imperial throne, he had been kept, apparently not greatly against his will, in the background.

Nor, while his father lived, did he give any indications of a desire for power, or of any capacity for exercising it; but since he had been placed on the throne he had displayed great activity and energy, though he was still, in the opinion of many, more of a philosopher--a detractor might said more of a pedant--than of a statesman.

He studied theories of government, and was extremely fond of giving advice; and as both Louis and Marie Antoinette were persons who in many respects stood in need of friendly counsel, Mercy and Maria Teresa had both looked forward to his visit to the French court as an event likely to be of material service to both, while his sister regarded it with a mixed feeling of hope and fear, in which, however, the pleasurable emotions predominated.
She was not insensible to the probability that he would disapprove of some of her habits; indeed, we have already seen that he had expressed his disapproval of them, and of some of her friends, in the preceding year; and she dreaded his lectures; but, on the other hand, she felt confident that a personal acquaintance with the court would prove to him that many of the tales to her prejudice which had readied him had been mischievous exaggerations, and that thus he would be able to disabuse their mother, and to tranquilize her mind on many points.

She hoped, too, that a personal knowledge of each other by him and her own husband would tend to cement a real friendship between them; and that his stronger mind would obtain an influence over Louis, which might induce him to rouse himself from his ordinary apathy and reserve, and make him more of a man of the world and more of a companion for her.

Lastly, but probably above all, she thirsted with sisterly affection for the sight of her brother, and anticipated with pride the opportunity of presenting to her new countrymen a relation of whom she was proud on account of his personal endowments and character, and whose imperial rank made his visit wear the appearance of a marked compliment to the whole French nation.
High-strung expectations often insure their own disappointment, but it was not so in this instance; though the august visitor's first act displayed an eccentricity of disposition which must have led more people than one to entertain secret misgivings as to the consequences which might flow from a visit which had such a commencement.
