Indeed, very few dynastic marriages were happy and ended well -- but at least, MA and her sisters had children. Some did not have children at all so there was nothing for the spouses to work on the relationship. I think there were sadder cases than theirs....but that does not negate how bad I feel about what they had to go through.
Perhaps Mimi's love affair was 'not so serious' to threaten her marriage. Apparently, Maria Theresa knew about it but there was nothing in the book that said she was displeased with her favorite child, let alone punished her about it. It's sad that MT seemed to be so unfair to the rest with her scoldings, etc. yet be so lenient with her Mimi. Her punishment to her wild child, Amalia in Parma, seemed excessive to me (the banning of the letters). Later on, she would write Count Mercy in Paris (circa 1773) how sorry she was for her daughter (Amalia)..... with that fool of a husband but would not permit her to visit Vienna. Huh? She forced and forced her daughter to marry Ferdinand of Parma and when later on, she would (almost, but not quite in public) admit her daughter's 'excessive' behavior was 'understandable' with that sort of husband, but she wouldn't even grant her a visit? That was the sort of parenting she practiced on her children, and I, for one, completely sympathize with them for coping with their situation in whatever way they could....
In the book on Joseph by Derek Beales, it was said that when not combating and lecturing Joseph in Vienna, MT wrote (or rather scolded, a more apt term) her married children every week. She blamed Leopold for his coldness and reserve, Ferdinand for not making better use of his time, Amalia for her poor French and haughty ways, MA for her laziness, frivolousness, extravagance, and failure to turn every opportunity to conceive a child. Carolina was not mentioned in that section but I'm sure MT did not spare her. I'm sure the list of complaints went on and on. Now Mimi, MT did not seem to scold, take note...... she was certainly unfair to the rest -- and not only with regards to Mimi's love match. It seems to me that Mimi was the unpleasant child yet Mimi could do no wrong in MT's eyes. It is no wonder the rest rebelled in different degrees and ways.
I think the sisters were, in a way, glad to swap their over-controlling and unfair mother with husbands they themselves can control (albeit different degrees--- MA had less success in this matter than Carolina or Amalia). Their sister Elisabeth, left behind in Vienna, certainly complained of their mother's controlling nature --- she said such control over a daughter her age (she was in her 30s then, I think) was outrageous! MT did not think much of Marianne as well -- as she was an invalid and therefore not 'useful' in terms of Austria's foreign policy/alliances. It was said that MT was 'justified' in marrying off her children to cement alliances as she was Empress before Mother --- and I do agree up to a certain point. But as a parent, she didn't appear to be loving or at the very least, she did not know how to show her love in a constructive way that would bring about positive results---with her favoritism of Mimi, 'neglect' of Marianne, and her scolding ways/control over her other children, the perennial distrust (including sending spies on her children), her indiscretion (i.e. she cared not who knew of her battles with Joseph), and the way she would play off one child against the other and also complain to one about another. Very sad and quite nasty. I think we can all agree that she was truly preoccupied with her children, especially once they were married and ran into problems, writing letters full of advice and reproach until the early hours of the morning. She was indeed very preoccupied with MA, Amalia, and Carolina, and that definitely spiked up her stress levels and she suffered a great degree of distress over them. But her method seemed to be unyielding....Had she tried a different tack in guiding her children, things could have been very different and more positive. Certainly MA and Amalia could have benefited much from it.
I know only one portrait of Maria Amalia of Saxony, and a group one at that..... but you can see her quite clearly. Grace Angel, I can send it to you via PM if you're interested. I agree that Saxony's princesses then were not known for their beauty or glamor.
I agree that a low-profile, plain consort for Louis XVI would not likely arouse jealousy or spite at Versailles but....poor princess nevertheless.
