Who was all associated with Maria Theresa except?

Maria Theresa, the only female ruler of the Habsburg dominions, was associated with several key figures, including her husband, Francis I, Holy Roman Emperor, and her children, such as Joseph II and Marie Antoinette. She also collaborated with advisors like Wenzel Anton von Kaunitz, who played a crucial role in her foreign policy. However, notable figures such as Frederick the Great of Prussia were not allies but rather rivals during her reign, particularly during the War of the Austrian Succession.
