I am inclined to think that Maria Elisabeth never favored her mother´s (and Joseph´s) attitude towards Maria Amalia. It´s only a presumption, but ME seems to have had a "mind of her own" (her sharp tongue, her tantrums, her prolongued silences), even if she wasn´t given much importance within her family or at the Viennese court (Leopold seems to have been more benevolent towards her, increasing her allowance when he became Emperor). Liesl and Mali were only 2 and a half years apart, and the closest sister the latter had in age (aside from the baby Maria Carolina -the second of the three with that name- who died at birth; Joanna Gabriela was four years younger than Maria Amalia). Maria Christina was only a year older than Maria Elisabeth, but seems to have been more independent, more "mature" (with her many talents). She seems to have been placed more in the lot of the elder children (Marianne and Joseph), while the more frivolous Elisabeth seems to have been often paired with Amalia (possibly close to Charles and Leopold, although the boys must have had a different education and a more masculine environment). Sad that no letter from Maria Elisabeth seems to have survived (that I know of) to see what she really thought of Maria Amalia´s ostracism. The very warm reception she gave her younger sister in 1783 clearly indicates she was not in favor of it. I wonder what did she think of Marie-Antoinette, of Maria Christina (according to Kutschera, citing a letter of Leopold, it seems they abhorred each other...), etc. By the way, I just saw a fantastic exhibition at the Metropolitan Museum in New York, called "Vienna, 1780", showing the fabulous "second silver table service" of Maria Christina and her husband, Duke Albert of Saxe-Teschen, that they used while being Governors of the Low Countries. The exhibition is only open until this November 7 (reason why I dashed to see it), but there is a very informative (and beautifully illustrated) hard-cover catalogue, that anyone can acquire online.
